Business Insurance With a Claims History | UK 2026
Business Insurance With a Claims History: The Definitive UK Guide for 2026
Why does a claims history need specialist insurance treatment?
A claims history is the single most powerful number an underwriter sees before they decide whether to quote your business — and at what price. Every commercial proposal asks for it, every renewal is re-rated against it, and a poor one can quietly close the door at dozens of insurers before a human ever reads your file.
That is the problem we solve every week at Miller & Partner. A business with one large fire claim, a run of liability losses, or a string of small attritional claims is not uninsurable — but it is "non-standard". The automated panels behind comparison sites and direct insurers are built to decline non-standard risk on sight, because their loss models cannot price what they cannot categorise. The result is a frustrating loop of refusals that has nothing to do with whether the business is actually well run.
This guide explains exactly how a claims history is disclosed, scored, loaded and — crucially — rehabilitated. It sits alongside the two placement pages a loss record most often leads to — business insurance after insolvency, where the claims record sits behind a formal procedure, and business insurance with a CCJ, where adverse credit compounds the loss history — and our companion guides on insurance for businesses refused cover and choosing a specialist adverse-risk broker. Where those articles focus on the moment of refusal, this one is about the loss record itself: how to present it fairly under the Insurance Act 2015, how underwriters turn it into a loss ratio, and how to rebuild insurer confidence over a renewal cycle.
The market context matters in 2026. Capacity is broadly competitive and pricing on clean, well-controlled risks is flat to slightly down — but underwriters are sharpening their focus on loss-heavy segments and rewarding businesses that can demonstrate strong controls and a clean recent record. In a soft market, the gap between a well-presented adverse risk and a poorly-presented one is wider than ever. The presentation is the lever, and that is where a specialist broker earns their place.
Key facts at a glance
- Most commercial proposal forms ask for five years of claims experience; some ask for three — but the legal duty under the Insurance Act 2015 is wider than the question.
- Claims are visible on the Claims and Underwriting Exchange (CUE) for six years from the date the claim is closed — including incidents that never resulted in a payout.
- A single at-fault claim commonly influences rating for three to five years; large or repeat-pattern losses shape terms for longer.
- Under the Insurance Act 2015 you must disclose every material circumstance you know or ought to know — including incidents that did not become claims.
- For innocent non-disclosure, insurers now have proportionate remedies — not the old all-or-nothing right to void the policy.
- A fraudulent claim lets the insurer refuse it entirely, recover sums paid and terminate cover from the date of the fraudulent act (Section 12).
- The ABI reports insurers detected 84,400 fraudulent claims worth £1.1 billion in 2023 — which is why every loss record is now scrutinised.
How does a clean record compare to an adverse claims record at renewal?
The clearest way to understand the impact of a claims history is to see how the same business is treated with a clean versus an adverse record. The risk has not changed — the loss experience has. This is what shifts at renewal:
| Underwriting factor | Clean record (no claims 5 yrs) | Adverse record (multiple / large claims) |
|---|---|---|
| Market access | Full standard panel, comparison sites, direct insurers | Standard panel auto-declines; specialist MGAs and Lloyd's required |
| Premium | Base rate, often discounted in a soft market | Loaded 25%–200%+ depending on frequency and quantum |
| Excess / deductible | Standard policy excess | Increased and/or claim-specific excesses imposed |
| Policy terms | Standard wording | Warranties, conditions precedent, exclusions on loss-affected perils |
| Underwriting route | Largely automated / algorithmic | Individually referred to a human underwriter |
| Information required | Basic proposal | Full claims experience, root-cause notes, risk-improvement evidence |
| Renewal stability | Predictable year-on-year | Volatile until a clean run rebuilds confidence |
How does The Insurability Framework™ place a heavy loss record?
Placing a business with a difficult claims history is exactly what The Insurability Framework™ was built for. It is our structured method for turning a risk that standard markets reject into one a specialist underwriter can confidently quote. Here is how each of the four pillars applies to an adverse loss record.
Underwriter Intelligence
We know which insurers and MGAs have appetite for your sector and tolerate your specific loss pattern — and what evidence moves their decision from decline to quote. We present to the right desk first.
Difficult Risk Expertise
Heavy loss records, prior refusals and repeat claims are our core business, not an exception we shy away from. We place risks that standard panels decline on sight, via Lloyd's syndicates and specialist schemes.
Risk Assessment
We identify the hidden exposures behind the headline claims — the root cause, the controls now in place, the trends an underwriter fears — and build a fair presentation that addresses each one before it is asked.
Claims Advocacy
When the next claim comes, real people handle it — fairly and promptly. A well-managed claim protects your future loss ratio, which is the very thing that decides your renewal terms.
What must you disclose about past claims under the Insurance Act 2015?
This is the most important — and most misunderstood — part of insuring a business with a claims history. The Insurance Act 2015 replaced the old duty of disclosure with a duty of fair presentation. For commercial (non-consumer) policies, you must disclose every material circumstance you know or ought to know, in a manner that is reasonably clear and accessible, after a reasonable search of the information available to you.
A material circumstance is anything that would influence the judgement of a prudent insurer in deciding whether to take the risk and on what terms. Your claims and loss history is the textbook example. Critically, the duty is wider than the proposal form question. If the form asks for five years but you are aware of a relevant incident from six years ago that bears on the risk, the safe course is to disclose it.
What "claims history" actually includes
- Paid and outstanding claims — settled losses and any still open or reserved.
- Incidents and circumstances that did not become claims — a near-miss, a notified circumstance, a complaint that could escalate. These are routinely missed and routinely material.
- Losses regardless of whether they were insured — including uninsured losses and losses at a previous premises or under a previous trading name.
- Claims and convictions of directors, partners and key personnel — material facts extend to the people running the business, not just the business itself.
- Anything arising after a quote is issued — if a loss occurs between quote and inception, it must be disclosed for the insurer's further consideration.
From recent placement conversations
"The most avoidable problem I see is a business owner who 'forgets' an incident because it never turned into a claim — a small flood that was cleaned up, a slip that was dealt with informally, a dispute that fizzled out. They are not being dishonest. But under the Insurance Act 2015 a notified circumstance can be every bit as material as a paid claim."
"When we take a new client with an adverse record, the first thing we do is build a complete, honest loss summary together — including the awkward ones. It feels counter-intuitive to volunteer the bad news, but a fair presentation is what protects the next claim and, frankly, what gets the better underwriters to engage at all."
How do underwriters actually score a claims history?
Underwriters do not simply count claims. They read a loss record for three things, and a specialist broker builds the presentation to answer all three before the underwriter has to ask.
Frequency: how often do losses happen?
A pattern of small, repeated "attritional" claims often worries an underwriter more than a single large one. Frequency suggests a systemic control problem — something about how the business operates that keeps generating losses. Three £2,000 claims a year for three years is a harder story than one £80,000 claim caused by a one-off event that has since been engineered out.
Severity: how big is the worst loss?
Quantum tests whether the business's risk could produce a loss large enough to threaten the insurer's book. A single catastrophic claim is forgivable if its cause is clearly understood and addressed. What underwriters fear is severity and frequency together, or a severe loss with no convincing explanation.
Trend and root cause: is the risk improving or deteriorating?
This is where presentation wins or loses the case. An underwriter wants to see that you understand why each loss happened and what has changed since. Evidence of risk improvement — new procedures, training, equipment, accreditations — turns a static bad record into a credible recovery story. The same loss history with and without a root-cause narrative can produce wildly different terms.
What is a loss ratio and why does it decide your premium?
The loss ratio is the number that ultimately governs your renewal. It is the proportion of premium an insurer pays back out in claims, expressed as a percentage: claims incurred divided by premium earned. If you pay £10,000 in premium and the insurer pays £6,000 in claims, your loss ratio is 60%.
As a rough industry guide, an account that consistently runs a loss ratio above roughly 70%–80% is unprofitable for the insurer before their own costs are even added. That is the threshold that drives the decisions you feel at renewal: a premium increase, a higher excess, restricted terms, or non-renewal. Understanding your own loss ratio is the single most useful thing you can do before approaching the market — it tells you how an underwriter will see you.

How long do claims stay on the CUE database and your record?
The Claims and Underwriting Exchange (CUE), run by the Motor Insurance Bureau, is a central database of incidents and claims reported to insurers across motor, home, travel and personal-injury lines. Entries are held for six years from the date the claim is closed. Insurers check it to verify what you disclose and to detect undisclosed claims.
Two points matter for commercial buyers. First, CUE records incidents even where no payout was made — so a reported event you never claimed on can still appear. Second, where a commercial line is not on CUE, insurers maintain their own internal records and increasingly share data through sector-specific exchanges. The practical effect is the same: assume any past loss is discoverable, and disclose it. If an insurer finds an undisclosed claim on a database, your current claim can be rejected and your fair presentation called into question.
Does a claim ever fully "disappear"?
For rating purposes, claims fade rather than vanish. Most proposals ask for three to five years, and a claim's influence on price typically tapers over the same period. After the relevant window it stops being a routine rating factor, though insurers may still hold internal records beyond six years where fraud or disputes were involved. The combination of the proposal window and the CUE six-year retention is why a focused, well-timed recovery plan works.
Why do standard insurers decline a business with prior claims?
A decline rarely means a business is genuinely uninsurable. It usually means the risk does not fit the narrow, automated appetite of a standard insurer. The common reasons are mechanical rather than moral:
- Algorithmic underwriting. Comparison panels and direct insurers price by model. A loss record outside set parameters triggers an automatic referral or decline — no human reads the context.
- Appetite, not affordability. The insurer has simply decided not to write your sector-plus-loss-pattern combination this year. It is a portfolio decision, not a judgement on your business.
- Poor presentation. When information lacks context, underwriters default to caution. A bare list of claim figures with no root-cause narrative invites a decline that a fuller presentation would have avoided.
- No appeals process. Unlike a rejected claim, there is no formal route to challenge an underwriting decline. The only remedy is to re-present the risk to a market with the right appetite — which is precisely a broker's job.
If your business has already been turned away, our dedicated guide on insurance for businesses refused cover walks through the re-presentation process in detail, and our guide for businesses with CCJs covers the adjacent issue of adverse credit.
Renewal readiness: have you prepared your claims presentation?
Tick each item you have ready before approaching the market. The more you can present, the better the terms a specialist underwriter can offer. A green check is a point in your favour; an empty box is a gap to close.
What happens to your cover if a past claim was fraudulent?
The Insurance Act 2015 draws a sharp line between innocent error and fraud, and the consequences are very different. For an innocent failure to fairly present the risk, insurers now have proportionate remedies under Section 8: the insurer is put in the position it would have been in had the risk been fairly presented. If it would have charged more, the claim may be scaled down proportionately; if it would have declined, it can avoid the policy. The old all-or-nothing right to void for any non-disclosure is gone for genuine mistakes.
A fraudulent claim is treated entirely differently. Under Section 12, where an insured makes a fraudulent claim the insurer is not liable to pay it, may recover any sums already paid in respect of it, and may treat the contract as terminated from the date of the fraudulent act — keeping the premium. Earlier legitimate claims are protected, but everything from the fraudulent act onward falls away. This is why the ABI's figure of 84,400 detected fraudulent claims worth £1.1 billion in a single year matters to honest businesses too: it is the reason every loss record is now scrutinised, and the reason a clean, fully-disclosed presentation is so valuable.

How do you rehabilitate an adverse claims record over a renewal cycle?
An adverse claims history is a temporary state, not a permanent label. The businesses that recover fastest treat insurability as something they actively manage rather than something done to them once a year. The mechanics are predictable, and a specialist broker builds a multi-year plan around them.
Let the rating window do its work
Because rating is calculated over a rolling three-to-five-year window, every clean month moves an old claim closer to dropping out of the calculation. The most expensive renewal is usually the one immediately after a bad year; each subsequent renewal improves automatically as the loss ratio falls — provided no new claims replace the old ones. Timing your market approach to fall just after a claim ages out of the window can produce a noticeably better result.
Convert losses into a control narrative
The difference between a static bad record and a credible recovery is evidence. Every loss should be paired with a documented change: a near-miss reporting system, refreshed training, new equipment, an accreditation, a maintenance regime. Underwriters reward demonstrable risk improvement because it changes the forward-looking probability of loss — which is what they are actually pricing.
Manage the next claim well
Future loss ratio is built one claim at a time. Prompt notification, good documentation and active claims management keep individual claims smaller and cleaner, which protects the ratio that decides your next renewal. This is the practical face of the Insurability Framework's Claims Advocacy pillar — and a reason to have a broker who handles claims rather than a call centre that processes them.
Related regulatory and product considerations
Depending on your sector, an adverse record can intersect with other specialist covers. Businesses recovering from a major loss often need robust liability cover rebuilt carefully; those that suffered a data incident should review cyber insurance as a separate rating line, reporting breaches to the ICO where required; and any business that extends credit to customers may pair its recovery with trade credit insurance to protect against the knock-on effect of a customer's insolvency.
What drives the cost of insuring a business with a claims history?
Pricing an adverse record is not a single number — it is the sum of a dozen rating factors, each of which you can influence. The table below sets out the main drivers and the practical mitigation for each.
| Rating factor | Why it raises premium | Mitigation |
|---|---|---|
| Claim frequency | Repeated losses signal a systemic control problem | Document the control change behind each fixed cause; show a declining trend |
| Claim severity | A large loss threatens the insurer's profitability on the account | Evidence the root-cause fix; demonstrate the catastrophe cannot recur |
| Recency | A claim last month rates harder than one four years ago | Time the market approach to follow a clean spell where possible |
| Loss ratio | Above ~70% the account is unprofitable as-is | Know your figure; approach the market once it has fallen |
| Open / reserved claims | Uncertain ultimate cost forces a cautious reserve | Push for prompt, clean settlement of open claims before renewal |
| Sector loss profile | Some trades carry an inherently worse book-level record | Use a broker with the right MGA and Lloyd's appetite for your trade |
| Quality of presentation | No context = underwriter defaults to caution | Provide a full fair presentation with root-cause notes up front |
| Prior refusals / cancellations | A decline or cancellation is itself a material fact | Disclose and explain it; never conceal it |
| Director history | Prior insolvencies or claims of key people are material | Present openly with context on what has changed |
| Sums insured & limits | Higher limits magnify the cost of an adverse rate | Right-size limits to genuine exposure, not arbitrary round numbers |
| Excess level | A low excess transfers more attritional loss to the insurer | Accept a higher voluntary excess to signal confidence and cut premium |
| Risk-management evidence | Absence of controls is priced as worst-case | Supply training records, procedures, maintenance logs, accreditations |
From recent broker conversations
"Clients are often surprised how much a higher voluntary excess can move a premium on an adverse account. Taking the first £2,500 of any claim yourself tells the underwriter you genuinely expect not to claim — and it strips out the attritional losses that were dragging your loss ratio up in the first place. On the right risk it can be the single most effective lever we pull."
Three real claim case studies: how a claims history plays out
These fictionalised but realistic examples show how an adverse record is created, presented and recovered. Names and details are illustrative; the patterns are ones we see regularly.
Case study 1 — "Drayton Joinery": the attritional-frequency trap
Situation: A 14-staff joinery contractor accumulated four small Public Liability claims over three years — minor damage to client property on fit-outs, none over £6,000. Individually trivial; collectively a red flag.
Claim type: Public Liability (frequency, not severity).
The numbers: Total claims paid £19,400. At the next renewal the incumbent insurer non-renewed; three comparison-panel insurers declined automatically on the four-claim count.
What changed it: We presented a root-cause review showing every claim stemmed from one issue — inadequate dust and damage protection on site — now fixed with a mandatory site-protection checklist and toolbox-talk training. A specialist contractor MGA quoted with a £1,000 each-and-every-claim excess.
Lesson: frequency frightens underwriters more than a single big loss. A documented systemic fix turns "unreliable" into "improved".
Renewal impact: first renewal +48% on the original premium; second renewal, after a clean year, −22% as one claim aged out of the window.
Case study 2 — "Harbourside Bistro": the severity claim with a story
Situation: A seafront restaurant suffered a serious kitchen fire caused by a poorly-maintained extraction duct, with significant building damage and a four-month closure.
Claim type: Property (fire) plus Business Interruption.
The numbers: Buildings and contents £214,000; business interruption £61,000; total £275,000. The following year the restaurant could not place cover on the open market.
What changed it: We built a presentation around the post-fire works — new fire-suppression system over the range, a contracted quarterly duct-cleaning regime with certificates, and updated staff fire training. The cause was demonstrably engineered out. A Lloyd's-backed hospitality scheme quoted with a fire-protection warranty.
Lesson: a single severe loss is forgivable when the cause is understood and provably fixed. Underwriters price the future, not the past.
Renewal impact: +85% at first post-claim renewal with a fire-suppression warranty attached; settling toward +30% over the open market by year three as confidence rebuilt.
Case study 3 — "Meridian Surveying Ltd": the claims-made PI disclosure gap
Situation: A surveying firm received a complaint about a valuation that hinted at a future claim, but did not notify it as a circumstance. The following year they switched insurer for a cheaper premium. When the complaint became a formal Professional Indemnity claim, the new insurer examined disclosure.
Claim type: Professional Indemnity (claims-made; notified-circumstance dispute).
The numbers: Claim valued at £140,000 plus £28,000 defence costs. Because the circumstance pre-dated the new policy and had not been notified, coverage was contested.
What changed it: The position was salvaged only because the original (lower) defence-and-settlement could be argued back to the prior insurer's period — an expensive, avoidable dispute. We now run a structured circumstance-notification review with all PI clients at renewal.
Lesson: on claims-made PI, a notified circumstance is as material as a paid claim. Chasing a cheaper premium while sitting on an un-notified circumstance is the costliest false economy in commercial insurance.
Renewal impact: +60% and a £25,000 each-claim excess once the dispute was on record; the firm now treats circumstance notification as a board-level renewal task.
How do you manage a claim to protect your future insurability? (8 steps)
How you handle a claim today directly shapes the loss ratio that prices your next renewal. Follow these steps to keep each claim as clean and contained as possible.
- Notify immediately. Tell your broker or insurer as soon as you are aware of an incident or circumstance — even if you are unsure whether you will claim. Late notification can prejudice the claim and breach policy conditions.
- Preserve evidence. Photograph damage, keep receipts and damaged items, and record witness names before the scene changes.
- Make the situation safe. Take reasonable steps to prevent further loss (a policy duty) — but do not dispose of anything or admit liability.
- Do not admit liability. Report facts only. Admitting fault can prejudice the insurer's position and your defence; leave liability decisions to the claims handler.
- Document the root cause. Record what caused the loss and start a corrective action. This becomes your risk-improvement narrative at the next renewal.
- Cooperate with the loss adjuster. Respond promptly and fully. A clean, well-evidenced file settles faster and smaller.
- Track the claim to settlement. Stay engaged until it closes. Open and reserved claims rate harder than settled ones.
- Update your fair presentation. Add the claim and the corrective action to your loss summary so it is ready to disclose accurately at renewal and to any new insurer.

Glossary: claims-history and adverse-risk insurance terms
- Adverse risk
- A risk that falls outside standard insurer appetite — often due to claims history, prior refusal, insolvency or sector — requiring specialist placement.
- Attritional claims
- Frequent, relatively small losses. A high frequency of attritional claims often concerns underwriters more than a single large loss.
- Claims-made basis
- A policy (typically Professional Indemnity) that responds to claims first made during the policy period, making notified circumstances highly material.
- CUE (Claims and Underwriting Exchange)
- A central UK database of reported incidents and claims, held for six years from claim closure, used by insurers to verify disclosure.
- Duty of fair presentation
- The Insurance Act 2015 obligation on commercial buyers to disclose every material circumstance they know or ought to know, clearly and accessibly.
- Each-and-every-claim excess
- An excess applied separately to every individual claim, as opposed to once per policy period.
- Loss ratio
- Claims incurred divided by premium earned, as a percentage. Above roughly 70%–80% an account is unprofitable for the insurer.
- Material circumstance
- Anything that would influence a prudent insurer's decision to take a risk or set its terms — including claims history.
- MGA (Managing General Agent)
- A specialist intermediary with delegated authority to underwrite on an insurer's behalf, often serving niche or adverse risks.
- Notified circumstance
- An event reported to an insurer that may give rise to a future claim. On claims-made policies it is as material as a claim itself.
- Proportionate remedy
- Under the Insurance Act 2015, the insurer's response to innocent non-disclosure — placing it in the position it would have held had the risk been fairly presented, rather than voiding outright.
- Reserved claim
- An open claim for which the insurer has set aside an estimated amount. Uncertain ultimate cost makes reserved claims rate harder than settled ones.
- Root-cause narrative
- A documented explanation of why each loss occurred and what has been changed to prevent recurrence — central to a strong presentation.
- Loading
- An increase applied to a base premium to reflect elevated risk, commonly expressed as a percentage uplift.
