General information — not advice. This guide explains how the law on non-disclosure and avoidance generally works. It is not legal advice or personalised insurance advice, and it does not take account of your own circumstances. If your policy has been avoided you should take specialist legal or broking advice on your specific facts.

What does it mean when an insurer voids your policy?

Voiding — properly called avoidance — means the insurer treats the policy as if it never existed. Not cancelled from today: unwound from inception. Every claim is refused, including ones already paid, and you are retrospectively uninsured for the whole period. But here is what most businesses are never told: since the Insurance Act 2015, avoidance is no longer the automatic remedy for non-disclosure. The insurer must show your breach was deliberate or reckless, or that it would not have written the risk at all on any terms. In every other case the law requires a proportionate remedy instead.

Key facts at a glance

  1. The Insurance Act 2015 abolished avoidance as the single remedy for breach of the disclosure duty in commercial insurance, for contracts entered into from 12 August 2016. It replaced it with a system of proportionate remedies set out in Schedule 1.
  2. Avoidance with the premium retained is only available where the breach was deliberate or reckless. That is a high bar, and the burden of proving it sits with the insurer.
  3. Where the breach was careless, the insurer can only avoid if it can show it would not have entered into the contract at all on any terms — and even then it must return the premium.
  4. If the insurer would still have written the risk but on different terms, the policy stands and is simply treated as though those terms had applied. It is not avoided.
  5. If the insurer would have charged a higher premium, the claim is reduced proportionately. If the premium would have been double, the claim is halved — but the policy remains in force.
  6. The insurer must produce evidence of what the actual underwriter would have done. This puts the underwriter's contemporaneous position front and centre, and it is frequently where an avoidance is weakest.
  7. "Basis of contract" clauses were abolished for commercial insurance by the Act, so an insurer can no longer convert every proposal answer into a warranty and treat a minor inaccuracy as fatal to the policy.

Few things frighten a business owner more than a letter saying the policy has been avoided. It usually arrives at the worst possible moment — after a fire, a serious injury claim, or a theft — and it says, in effect, that the protection you have been paying for was never there. The instinct is to assume the insurer must be right and start counting the cost.

That instinct is often wrong. The law changed materially in 2016 and a great deal of the sector's folk memory has not caught up with it. Under the old regime an innocent, immaterial error could genuinely destroy a policy. Under the current regime it cannot. An insurer that reaches for avoidance has to justify it against a statutory framework that, in most careless cases, points to a lesser remedy.

This guide explains what avoidance actually is, what the insurer has to prove, where avoidances are commonly vulnerable, and — because this is what most readers need — how cover gets re-placed afterwards. It sits in our adverse risk hub alongside guides on cover refused elsewhere and insurance with a claims history.

12 Aug 2016 Insurance Act 2015 in force — proportionate remedies replaced automatic avoidance
Insurer Carries the burden of proving deliberate or reckless breach, not you
Ab initio Avoidance unwinds the policy from inception, not from the date of discovery
Premium back Must be returned where the breach was careless rather than deliberate or reckless

How does the Insurability Framework apply after avoidance?

An avoided policy is one of the hardest disclosures in commercial insurance — harder than a large claim, and in some markets harder than an insolvency, because it goes to trust rather than to loss. The Insurability Framework™ is how we present it so the risk is underwritten on what actually happened and what changed, rather than on the word "avoided" in a proposal form.

The Miller & Partner Method

Four pillars applied to every post-avoidance placement. The objective is to present the full circumstances and the corrective action — because an avoidance disclosed properly with context is placeable, and one that surfaces later on a search is not.

01

Underwriter Intelligence

Markets differ sharply on avoidance. Some decline outright; others distinguish carefully between a careless omission and a deliberate misstatement, and will write the former. Knowing which is the difference between a placement and a trail of declines that then have to be disclosed in turn.

02

Difficult Risk Expertise

Businesses whose policy has been avoided, who have an unresolved coverage dispute running, who were let down by a previous broker's proposal handling, or who are carrying an avoidance alongside a claim or a CCJ. These are ordinary submissions here rather than reasons to stop.

03

Risk Assessment

We work out what was actually not disclosed and why, whether the avoidance itself looks sound under the Act, and — critically — what has changed in how the business presents risk. That last part is what a new underwriter is buying.

04

Claims Advocacy

Where a claim is caught up in the avoidance, the two run together. We handle the insurer relationship, make sure the proportionate-remedy question is actually asked, and coordinate with your legal advisers rather than leaving you to argue it alone.

Is avoidance still the automatic remedy for non-disclosure?

No — and this is the single most important thing to understand. For commercial policies entered into from 12 August 2016, the Insurance Act 2015 replaced the old all-or-nothing rule with proportionate remedies. Avoidance survives only in defined circumstances: where the breach was deliberate or reckless, or where the insurer can prove it would not have written the risk at all had the true position been presented. Anything else calls for a lesser remedy.

Before the Act, English insurance law operated on "utmost good faith" and a single, brutal consequence. If you failed to disclose something material — even innocently, even trivially — the insurer could unwind the entire policy. That produced outcomes most people would recognise as unjust: a business losing all cover over an error that would have made no difference to the underwriting decision.

The Act deliberately dismantled that. Two changes matter most:

  • Proportionate remedies. The insurer's remedy now depends on what the underwriter would actually have done had the risk been presented fairly. If they would have charged more, the claim is reduced by that proportion. If they would have imposed different terms, those terms are read into the policy. The cover survives in both cases.
  • Basis of contract clauses abolished. Insurers can no longer convert every answer on a proposal form into a warranty, so a minor inaccuracy on a peripheral question can no longer be used to bring down the whole contract.

The practical consequence is that an avoidance letter is a position, not a verdict. It may be entirely correct. It may also be an insurer reaching for the strongest remedy when the Act points to a weaker one. The only way to know is to ask what the underwriter would have done — which is precisely the question the Act requires to be answered.

One important boundary These proportionate remedies apply to non-consumer (business) insurance under the Insurance Act 2015, and to contracts entered into or varied from 12 August 2016. Consumer policies are governed by separate but broadly parallel rules under the Consumer Insurance (Disclosure and Representations) Act 2012. If your policy predates August 2016, or if the arrangement is a personal rather than a business one, the analysis differs — take advice on your specific facts.

What are the proportionate remedies under the Insurance Act 2015?

Four outcomes, and only the first two involve losing the policy. Deliberate or reckless → avoidance, all claims refused, premium retained. Careless and the insurer would not have written it at all → avoidance, but premium returned. Careless and different terms would have applied → policy stands on those terms. Careless and a higher premium would have been charged → claim reduced in proportion, policy stands.

What the insurer must show Remedy available Does the policy survive?
Breach was deliberate or reckless Avoid the contract, refuse all claims, keep the premium No
Careless — insurer would not have written the risk on any terms Avoid the contract, refuse all claims, return the premium No
Careless — insurer would have written it on different terms Policy treated as though those terms applied from the start Yes
Careless — insurer would have charged a higher premium Claim reduced proportionately (premium ×2 → claim halved) Yes
Both different terms and higher premium would have applied Both remedies can apply together — terms read in and claim reduced Yes
Breach not material, or insurer not induced by it No remedy — there is no qualifying breach at all Yes

Two things follow from that table which are worth sitting with. First, most of the possible outcomes leave your policy intact. Second, the difference between "avoided, premium kept" and "claim reduced by 40%" is not a matter of degree — it is the difference between a business-ending event and a painful but survivable one, and it turns on a characterisation of your state of mind at proposal.

How is deliberate or reckless breach different from careless?

Deliberate means you knew the information was material and knew you were not disclosing it. Reckless means you did not care whether it was material or not. Careless is everything else — forgetting, misunderstanding a question, assuming something was irrelevant, relying on a broker who did not ask. The insurer bears the burden of proving deliberate or reckless conduct, and it is a genuinely high bar.

This distinction decides the outcome, so it is worth understanding what tends to fall on each side of the line.

Typically treated as careless:

  • Forgetting a claim from several years ago, particularly a small one that was closed without payment
  • Misunderstanding what a proposal question was asking — for example whether "any director" included a dormant company directorship
  • Assuming a fact was not relevant because nobody asked about it directly
  • Relying on a broker to elicit the right information and not being asked the right question
  • An honest error in a sum insured, a turnover figure or a headcount
  • Not realising an incident was reportable because no claim was ever made

More likely to be argued as deliberate or reckless:

  • Answering "no" to a direct, unambiguous question about a matter you plainly knew about
  • A pattern of non-disclosure across several renewals rather than a single omission
  • Concealing something after being specifically asked about it in correspondence
  • Disclosing to one insurer but not another, where the difference looks calculated
  • Non-disclosure of something that would obviously be material to any underwriter — a recent unspent conviction, a large open claim, a previous avoidance
From recent placement conversations The conversation I have most often after an avoidance is with someone who is convinced they have done something terrible. They usually have not. What has typically happened is that a proposal form asked a broad question, they answered it the way any reasonable person would read it, and an underwriter has since taken a different view of what the question covered. That is the definition of careless rather than deliberate, and under the Act it points towards a proportionate remedy rather than avoidance. The reason it does not get argued is that nobody tells the business owner the argument exists. They get the letter, they assume it is final, and they start again from nothing.

On what grounds can you challenge an avoidance?

Four main lines. Materiality — would a prudent underwriter actually have cared? Inducement — did this insurer genuinely rely on it in writing the risk? Characterisation — was the breach really deliberate or reckless rather than careless? And the counterfactual — can the insurer actually evidence that it would have declined the risk outright, rather than merely charged more?

Each of these is a question the insurer has to be able to answer, and in practice they are not always answered well.

Materiality

Information is material only if it would influence the judgement of a prudent insurer in deciding whether to take the risk and on what terms. Not everything omitted is material. An insurer asserting materiality should be able to say specifically why this fact mattered to this class of risk.

Inducement

Beyond materiality in the abstract, the insurer must have been actually induced — it must show that this underwriter would have acted differently. If the underwriting file shows the same terms were applied to comparable risks that did disclose the fact, inducement becomes difficult to sustain.

Characterisation of the breach

Since deliberate or reckless conduct unlocks the harshest remedy, insurers have an incentive to characterise breaches that way. The burden of proof is theirs. Evidence of an honest, explicable misunderstanding — particularly a broad or ambiguous proposal question — pushes hard the other way.

The counterfactual

This is frequently the weakest link. To avoid on a careless breach the insurer must prove it would not have written the risk at all, on any terms. That is a strong claim. Many risks that look unattractive would still have been written at a higher premium or with a tighter excess — and if that is what the underwriter would have done, the remedy is proportionate, not avoidance.

Where to take a challenge A dispute can be raised through the insurer's own complaints process first. Beyond that, micro-enterprises and small businesses meeting the eligibility criteria may be able to refer a complaint to the Financial Ombudsman Service, which can consider whether the outcome was fair and reasonable, not only whether it was legally available. Larger businesses generally need to pursue it through solicitors. Time limits apply in both routes, so take advice early rather than after months of correspondence.

What to do next — by situation

Select the position you are actually in. This is general information about the options rather than advice on your case — for that, see our adverse risk guides or speak to us directly.

    Avoidance response self-check

    Tick what you have already done. The unticked items are usually where a position is lost — not through the original non-disclosure, but through how the aftermath was handled.

    • You have the avoidance letter in writing, stating exactly what was not disclosed and which remedy is being applied
    • You have asked whether the breach is treated as deliberate, reckless or careless — the answer determines everything
    • You have asked what the underwriter would have done had the risk been presented fairly — terms, premium, or decline
    • You have retrieved the original proposal or statement of fact and can see the exact wording of the question at issue
    • You have kept all broker correspondence from the placement — what you were asked and what you told them
    • You have confirmed whether the premium has been returned — it must be, unless the breach was deliberate or reckless
    • You have arranged replacement cover — being uninsured while you argue is a separate and worse exposure
    • You have checked whether employers' liability was involved, since a gap there is a legal problem as well as a commercial one
    • You have raised a formal complaint with the insurer if you think the remedy is wrong, starting the clock properly
    • You have taken advice on eligibility to refer to the Financial Ombudsman Service if you are a micro-enterprise or small business
    • You have documented what has changed in how you gather and present information for future proposals
    • You are prepared to disclose the avoidance at your next placement rather than hope it is not asked about
    0 of 12 done Start with the top three. Whether the insurer has characterised your breach as careless rather than deliberate is the question that decides which remedy the law actually permits.

    Re-placement difficulty assessor

    An indicative view of how a new market is likely to receive your business. This is general information only — not personalised advice, not a recommendation and not a quotation.

    What happens to your business after a policy is voided?

    Four things follow, and only the first is obvious. You are retrospectively uninsured for the whole policy period. Any claims already paid can be reclaimed by the insurer. You must disclose the avoidance at every future placement, effectively indefinitely. And if employers' liability was part of the avoided policy, you have a compliance problem as well as a commercial one, because that cover is a legal requirement.

    The retrospective element is what people find hardest to absorb. Cancellation stops cover from a date forward; avoidance removes it from the beginning. If a claim was paid eight months ago under a policy avoided today, the insurer can seek that money back. If a contract required you to hold cover throughout, you were technically in breach of it for the whole term.

    The consequences worth planning for:

    • Contractual breach. Most commercial contracts, leases and framework agreements require insurance to be maintained. Retrospective removal can put you in breach of every one of them for the relevant period, which may need disclosing to counterparties.
    • Employers' liability exposure. Employers' liability is compulsory for most UK employers. A retrospective gap is not simply an uninsured period — it engages a statutory obligation, and any employee injury during that window sits directly with the business.
    • Reclaimed settlements. Claims paid under the avoided policy can be recovered by the insurer, sometimes long after the money has been spent.
    • Disclosure obligations going forward. Proposal forms routinely ask whether any insurer has avoided, cancelled or refused cover. The answer is yes, and it stays yes.
    • Market perception. Avoidance reads differently from a claim. A claim says something happened to you; an avoidance implies something about how you present information. That is why the corrective-action evidence matters so much.
    • Cost. Expect a narrower panel, a higher premium and often a larger excess for a period afterwards.
    Deal with employers' liability first If the avoided policy included employers' liability and you have staff, that is the priority above the dispute, above the premium, above everything else on this page. Replacement EL cover should be in force before you do anything else, because the exposure is not only financial — it is a legal duty owed to your employees.

    Do you have to disclose a voided policy to future insurers?

    Yes — and failing to do so is far more dangerous than the original non-disclosure. Proposal forms ask directly whether cover has ever been avoided, cancelled, refused or made subject to special terms. Concealing an avoidance is exactly the pattern that makes a future breach look deliberate or reckless rather than careless — which is the difference between a reduced claim and a second avoidance with the premium retained.

    This is the single most consequential decision after an avoidance, and it is one people get wrong out of fear rather than dishonesty. The reasoning goes: the first insurer was unfair, disclosing it will make cover impossible, nobody will find out. All three assumptions are unsafe.

    Why disclosure is the right call, practically as well as ethically:

    • It is discoverable. Underwriters share information about avoidances and refusals through industry databases and market intelligence. It surfacing later, during a claim, is the worst possible sequence.
    • A pattern is fatal. One careless non-disclosure is explicable. A second, concealing the first, is very hard to characterise as anything but deliberate — and unlocks the harshest remedy available.
    • It is placeable when disclosed. Specialist markets write avoided risks routinely. What they will not write is one that arrives without warning.
    • Context travels with it. Disclosed properly, with an explanation and evidence of corrective action, an avoidance is a fact to be underwritten. Discovered, it is a credibility problem that cannot be repaired.

    How to disclose well. A short written account works better than a one-word answer: what the insurer said was not disclosed, why it happened, whether the premium was returned — which itself signals the breach was treated as careless — what the outcome was, and what has changed in how you now gather information before a proposal goes out. Three or four sentences, factual, no defensiveness.

    From recent placement conversations Every so often someone tells me halfway through a submission that there was an avoidance they had not mentioned, usually because a previous broker advised them it did not need declaring. It always comes out, and the damage is never the avoidance itself — it is that we are now presenting a business whose first instinct was to leave something out. I would far rather start with a client saying "this happened, here is the letter, here is what I have changed". That submission goes to market as an explicable problem with a fix attached. The other one goes nowhere, and the client cannot understand why the answer keeps being no.

    Was it your broker's fault rather than yours?

    Sometimes, and it is worth establishing early. A broker has a professional duty to elicit the information the insurer needs and to present it fairly. If you told them something and it never reached the insurer, or they never asked a question they should have asked, the failure may be theirs — and brokers carry professional indemnity cover for precisely this. That does not undo the avoidance, but it can determine who bears the loss.

    Two distinct situations, and they resolve differently:

    You disclosed and it was not passed on. If you told the broker about a claim, a conviction or a change in the business and it did not appear in the presentation to the insurer, the non-disclosure originated with them. Evidence matters here — emails, notes of calls, completed questionnaires. This is a straightforward professional negligence position.

    The broker never asked. Harder, but still meaningful. Brokers are expected to ask the questions their market will care about, and a broker who ran a placement without ever enquiring about claims history or previous refusals has arguably fallen short of the standard. Whether that carries depends on the facts and on what you might reasonably have volunteered unprompted.

    What to do: request the broker's placement file, put the complaint in writing so their PI insurer is on notice, and take advice if the sums justify it. Where the broker is a smaller firm and you are a micro-enterprise or small business, a complaint may be referable to the Financial Ombudsman Service subject to eligibility. Our guide to professional indemnity after a claim explains how PI responds from the other side of that conversation.

    What does cover cost after an avoidance?

    More than before, from a smaller panel — but the range is wide and driven by what was not disclosed and whether it looks careless or deliberate, far more than by your trade or turnover. Nothing here is a quotation or an indication of what you would pay. What consistently improves terms is a documented account of what happened and evidence of what changed.

    Factor Why it moves the outcome What helps
    Characterisation of the breach Careless is underwritable; alleged deliberate concealment narrows the panel severely. Evidence the breach was treated as careless — a returned premium is a strong indicator.
    What was not disclosed A forgotten small claim reads very differently from an undisclosed conviction. State it plainly with context rather than minimising it.
    Whether a claim was involved An avoidance that refused a live claim carries more weight than one with no loss attached. Explain the claim separately from the disclosure issue.
    Time elapsed Weight decays. Two or three clean years materially changes how it is read. Maintain continuous cover and a clean record; do not let anything lapse.
    Corrective action The main thing a new underwriter is actually buying. Document how information is now gathered and checked before any proposal.
    Other adverse history Avoidance plus CCJs or insolvency compounds rather than adds. See our CCJ and poor credit guide and insurance after insolvency.
    Number of avoidances One is an incident. Two is a pattern, and very few markets will look at it. Nothing repairs this quickly — continuity and time are the only levers.
    Broker presentation Adverse risks are placed on the quality of the submission more than any other class. Use a broker with genuine adverse market access rather than a panel.
    Sector An avoidance in an already-cautious sector compounds the difficulty. Specialist and Lloyd's markets where the mainstream panel has closed.
    Whether it is disclosed at all Concealment turns a placeable problem into an unplaceable one permanently. Disclose. Always.

    The shape is consistent: a careless omission with no claim attached, disclosed properly with evidence of a changed process, generally finds a home at a manageable loading. An alleged deliberate concealment, or an avoidance sitting alongside insolvency and CCJs, narrows the panel to specialists and prices accordingly. In both cases the submission does more work than the risk itself.

    Real avoidance scenarios and how they resolved

    The three scenarios below are illustrative composites written for this guide. They are not real clients and not actual claims, and the figures are indicative examples rather than outcomes we have handled. They show how the same statutory framework produces very different results depending on characterisation and evidence.

    Scenario 1 — Avoidance reduced to a proportionate remedy

    The situation: A manufacturing business suffered a £340,000 fire. During investigation the insurer found that a small water damage claim from four years earlier, settled at £3,800 under a previous policy, had not been declared. The proposal asked about claims "in the last five years". The director had genuinely forgotten it; the business had changed accountants and the paperwork sat with the previous firm. The insurer avoided the policy and refused the claim.

    What changed the outcome: The business asked two questions in writing — was the breach treated as deliberate, reckless or careless, and what would the underwriter have done had the claim been disclosed. The insurer's own file showed comparable risks with a single small water claim written at a modest loading. It could not sustain the argument that it would have declined the risk on any terms.

    Resolution: The insurer withdrew the avoidance and applied a proportionate remedy instead. The claim was reduced by 15%, reflecting the higher premium that would have been charged. Settlement £289,000 rather than nil. Professional fees in getting there, £14,000.

    Lessons: The avoidance was not sound under the Act, and it took two written questions to establish that. Nobody would have asked them if the business had accepted the letter at face value.

    Scenario 2 — Avoidance upheld, and the cost of concealing it

    The situation: A contractor's policy was avoided after the insurer discovered an undisclosed unspent conviction for a fraud offence. The proposal had asked the question directly and unambiguously. The premium was retained, indicating the insurer treated the breach as deliberate. No claim was outstanding, so the immediate loss was limited to the premium.

    What made it worse: At the next renewal the business answered "no" to a question about whether cover had ever been avoided. That policy was placed, ran for seven months, and was then avoided in turn when the first avoidance surfaced during an unrelated claim enquiry. The second avoidance refused a £62,000 claim.

    Resolution: The first avoidance was sound and was not challenged. The second was also sound — and considerably harder to argue against, because the concealment of the first made a deliberate characterisation straightforward. Both premiums retained. Net cost approximately £71,000, and a market position that took three years to rebuild.

    Lessons: The original conviction was placeable — specialist markets write disclosed convictions routinely. The concealment was not. The second decision cost far more than the first.

    Scenario 3 — Broker error rather than client non-disclosure

    The situation: A care provider's liability policy was avoided after the insurer found that a change of registered activity — the addition of a second site — had not been notified mid-term. The provider had emailed their broker about the new site six weeks before it opened and received an acknowledgement. The information never reached the insurer.

    What changed the outcome: The email chain was retrievable and unambiguous. The provider had disclosed; the broker had not passed it on. The complaint was put to the broker in writing, which put their professional indemnity insurer on notice.

    Resolution: The insurer maintained the avoidance, which was correct as against the presentation it had received. The loss shifted to the broker's PI insurer, which met the refused claim of £118,000 and the cost of arranging replacement cover at the loaded rate for two years, a further £9,400.

    Lessons: Where a broker sits between you and the insurer, the question is not only whether the information was disclosed but to whom. Keep the paper trail — that email chain was the entire case.

    How should you respond to an avoidance notice?

    Two things run in parallel and must not be allowed to block each other: testing whether the avoidance is actually sound, and getting replacement cover in force. Businesses that wait for the dispute to resolve before re-insuring frequently spend months uninsured — a larger exposure than the one they are arguing about.

    1. Do not respond substantively straight away. Acknowledge receipt, say you are taking advice, and do not admit anything about your state of mind at proposal. An avoidance letter is the insurer's position, not a determination.
    2. Ask for the characterisation in writing. Is the breach treated as deliberate, reckless or careless? This single answer determines which remedies the Insurance Act 2015 permits, and it should be stated plainly rather than implied.
    3. Ask what the underwriter would have done. Declined outright, applied different terms, or charged a higher premium? If the honest answer is either of the last two, avoidance is not the correct remedy for a careless breach.
    4. Retrieve the original proposal and the broker file. Read the exact question at issue. Broad, ambiguous or compound questions materially support a careless rather than deliberate characterisation.
    5. Check the premium. If it has been returned, the insurer has effectively accepted the breach was not deliberate or reckless — which narrows the remedies available to it and is useful to note.
    6. Arrange replacement cover immediately and in parallel. Employers' liability first if you have staff. Disclose the avoidance and note that it is disputed if it is.
    7. Put a formal complaint in if the remedy looks wrong. Use the insurer's complaints process, which starts the clock properly, and take advice on eligibility to refer to the Financial Ombudsman Service.
    8. Document what has changed. Whatever the outcome, the corrective action is what you present at every future renewal — and it is the thing that makes the avoidance underwritable rather than disqualifying.

    Glossary of terms

    Avoidance
    Treating an insurance contract as if it never existed, from inception. The formal term for what is commonly called "voiding" a policy.
    Ab initio
    From the beginning. Avoidance operates ab initio, which is why it removes cover retrospectively rather than from the date of discovery.
    Basis of contract clause
    Wording that converted every proposal answer into a warranty, so any inaccuracy could void the policy. Abolished for commercial insurance by the Insurance Act 2015.
    Careless breach
    A breach of the disclosure duty that was neither deliberate nor reckless. Attracts proportionate remedies rather than automatic avoidance.
    Deliberate or reckless breach
    Knowing the information was material and that you were not disclosing it, or not caring whether it was material. The only route to avoidance with the premium retained. The insurer bears the burden of proof.
    Duty of fair presentation
    The commercial policyholder's obligation under the Insurance Act 2015 to disclose every material circumstance it knows or ought to know, in a reasonably clear and accessible manner.
    Financial Ombudsman Service
    The independent body that can consider complaints from eligible consumers, micro-enterprises and small businesses about financial firms, including whether an outcome was fair and reasonable.
    Inducement
    The requirement that the insurer actually relied on the misrepresentation or non-disclosure in writing the risk. Without inducement there is no qualifying breach.
    Insurance Act 2015
    The legislation governing disclosure in UK commercial insurance for contracts entered into from 12 August 2016. Introduced proportionate remedies and abolished basis of contract clauses.
    Material circumstance
    Information that would influence the judgement of a prudent insurer in deciding whether to take the risk and on what terms.
    Misrepresentation
    An inaccurate statement of fact made to the insurer, as distinct from non-disclosure, which is a failure to state something at all.
    Proportionate remedy
    The remedies available for a careless breach — different terms read into the policy, or the claim reduced in proportion to the additional premium that would have been charged.
    Qualifying breach
    A breach of the duty of fair presentation which, but for the breach, would have caused the insurer to act differently. Only qualifying breaches attract a remedy.
    Rescission
    The unwinding of a contract from the beginning. Used interchangeably with avoidance in an insurance context.
    Voided policy
    Everyday term for an avoided policy. Distinct from a cancelled policy, which ends cover from a date forward rather than retrospectively.

    Frequently asked questions

    Voiding — properly called avoidance — means the insurer treats the policy as if it never existed, unwound from inception rather than cancelled from today. Every claim is refused, including any already paid, which the insurer can seek to recover. You are retrospectively uninsured for the whole period, which can also put you in breach of contracts, leases and framework agreements that required cover to be maintained. It is materially more serious than cancellation, which only ends cover from a date forward.

    Only in limited circumstances. Since the Insurance Act 2015 an insurer can avoid for a careless breach only if it can prove it would not have entered into the contract at all, on any terms — and even then it must return the premium. If it would have written the risk on different terms, those terms are simply read into the policy. If it would have charged more, the claim is reduced proportionately. In both of those cases the policy survives. Automatic avoidance for an innocent error was the old law and no longer applies to commercial policies entered into from 12 August 2016.

    Deliberate means you knew the information was material and knew you were not disclosing it. Reckless means you did not care whether it was material. Careless is everything else — forgetting, misreading a question, assuming something was irrelevant, or relying on a broker who never asked. The distinction decides the remedy: deliberate or reckless allows avoidance with the premium retained, while careless points towards proportionate remedies. The insurer bears the burden of proving deliberate or reckless conduct, and it is a high bar.

    Yes, and avoidances are challenged successfully more often than most businesses realise. The main lines are materiality — would a prudent underwriter actually have cared; inducement — did this insurer genuinely rely on it; characterisation — was the breach really deliberate rather than careless; and the counterfactual — can the insurer evidence that it would have declined the risk outright rather than merely charged more. That last point is frequently the weakest, because proving a risk would not have been written on any terms is a strong claim. Start with the insurer's complaints process and take advice early, as time limits apply.

    It depends on the characterisation, and the answer tells you something useful. If the breach was deliberate or reckless, the insurer can avoid the policy and keep the premium. If it was careless, the insurer must return the premium even where it is entitled to avoid. So a returned premium is a meaningful indicator that the insurer has treated the breach as careless rather than deliberate — which in turn narrows the remedies legally available to it. If you have been told the policy is void but the premium has been returned, that is worth pointing out.

    Yes. Proposal forms ask directly whether cover has ever been avoided, cancelled, refused or subjected to special terms, and the answer is yes indefinitely. Concealing it is far more dangerous than the original non-disclosure, because a second breach that hides the first is exactly the pattern that makes deliberate or reckless conduct straightforward to argue. Avoidances are also discoverable through industry information sharing. Disclosed with context and evidence of corrective action, an avoidance is placeable; discovered during a claim, it is not.

    Yes. Specialist and Lloyd's markets write avoided risks routinely, though the panel is narrower and the premium higher. What matters most is not the avoidance itself but how it is presented: a short factual account of what was not disclosed and why, whether the premium was returned, the outcome, and — most importantly to an underwriter — what has changed in how you gather and check information before a proposal goes out. Businesses that present that clearly are underwritten on the facts. Those that hope the question is not asked are not.

    That materially changes the picture and is worth establishing early. Brokers have a professional duty to elicit the information the insurer needs and present it fairly. If you told them something and it never reached the insurer, or they never asked a question they should have asked, the failure may be theirs — and brokers carry professional indemnity cover for exactly this. Retrieve every communication from the placement, request the broker's file, and put any complaint in writing so their PI insurer is on notice. The avoidance may stand, but the loss can shift.

    The insurer can seek to recover them. Because avoidance operates from inception rather than from the date of discovery, payments made under the policy were made under a contract now treated as never having existed. In practice this can mean a demand for repayment of a settlement received months earlier and already spent. It is one of the reasons avoidance is so much more serious than cancellation, and one of the reasons it is worth testing whether the avoidance is legally sound rather than accepting it.

    No, and the difference matters a great deal. Cancellation ends cover from a specified date forward, so the period before it remains insured and claims arising in that window stand. Avoidance unwinds the contract from inception, so there was never any cover at all and every claim falls away. Cancellation is also usually a commercial decision — non-payment, a change in appetite — whereas avoidance is a legal remedy for a breach of the disclosure duty. Both must be disclosed to future insurers, but they read very differently to an underwriter.

    There is no formal expiry. Proposal questions about avoidance are usually framed as "ever", so it remains disclosable indefinitely. In practice the weight it carries decays: an avoidance three or four years old, followed by continuous cover and a clean record, reads very differently from one that happened last month. What accelerates that is evidence — a documented change in how information is gathered, and an unbroken run of properly presented renewals since. What prevents it is any gap in cover or any suggestion the matter was not disclosed somewhere along the way.

    Look for one who asks what actually happened before quoting anything, who knows the difference between a careless and a deliberate breach and will ask the insurer to state which it is, and who has genuine access to specialist and Lloyd's markets rather than a mainstream panel that will simply decline. Miller & Partner approaches every placement through the Insurability Framework — underwriter intelligence, difficult-risk expertise, risk assessment and claims advocacy — which is what allows an avoided policy to be presented as an explicable event with a fix attached.

    About this guide This guide is general information about how the law on non-disclosure and avoidance works in UK commercial insurance. It is not legal advice, not personalised insurance advice, not a personal recommendation and not an offer of cover, and it does not take account of your own circumstances. If your policy has been avoided you should take specialist legal or broking advice on your specific facts. Cover is subject to insurer acceptance, underwriting criteria and the full terms, conditions, limits and exclusions of the policy issued. The scenarios in this guide are illustrative composites written for explanation; they are not real clients and not actual outcomes, and the figures are indicative examples. Legislation and regulatory positions are as at the date of publication and may change. Our full regulatory status and complaints information are set out in the footer of every page.

    Where the information comes from

    Our articles are compiled from a range of sources: regulators and public bodies such as the FCA, the Civil Aviation Authority, the Health and Safety Executive and Companies House; government publications and legislation; industry and trade bodies; insurer and market documentation; and published research and news reporting. Not everything stated originates from Miller & Partner. Where information comes from a third party we believe it to be accurate at the date of publication, but we haven't independently verified every external source and we don't warrant its accuracy or completeness. Where a point matters to a decision you're making, go to the original source and check it.

    Figures, examples and case studies

    Premium ranges, cost figures, limits and worked examples are illustrative only. They are not quotations, not offers of cover, and no cover is provided or implied on the basis of them. What you're actually charged depends on underwriting, and what you're actually covered for depends on the policy wording issued to you. Where an article includes a claim example, scenario or case study, it is illustrative unless we say otherwise — such examples are typically composites written to show how a policy section responds, and they don't describe an identifiable client, claim or settlement.

    Interactive tools

    Any calculators, cover checkers, risk assessors or similar tools on our site produce general guidance from the small number of answers you give them. They can't see your business, and their output is not a personal recommendation, an assessment of your actual risk, or a quotation.

    Rules and market conditions change

    Law, regulation, tax treatment, insurer appetite and policy wordings all change, sometimes at short notice. Content is accurate to the best of our knowledge on the date shown on the article and we don't undertake to update it as things move. An article you're reading some time after publication may be out of date.

    References to insurers, underwriters, trade bodies, software, training providers or other organisations are for information only. They don't imply endorsement, recommendation, partnership or affiliation in either direction unless stated. We're not responsible for the content of external websites we link to.

    Not legal, tax or accounting advice

    Nothing here is legal, tax, accounting or regulatory advice. Where an article discusses statutory duties, contract terms or compliance obligations, take advice from an appropriately qualified professional on your own position before acting.
