Yes, telecoms contractors can usually get insurance after a cable strike claim, but expect closer questioning and possibly tighter terms at first. A strike on a power cable, gas main, water pipe or another operator's duct is one of the most common liability claims in fibre and telecoms work, so underwriters see them regularly. What they want to know is why it happened and whether it is likely to happen again. Insurers who have paid a strike claim may raise the underground services excess, add conditions about plans and locating equipment, or decline to renew. Specialist and Lloyd's markets will often consider the risk if you can show the precautions you took, the findings of your own investigation, and the practical changes you have made since. A clear, honest presentation through a specialist broker is the single biggest factor in getting cover back on workable terms.

Key facts at a glance

  1. Strikes are common, not fatal. Underwriters expect them in this sector and look at how you manage the risk.
  2. Underground services terms vary. Policies may exclude, sub-limit or apply a higher excess to buried services damage.
  3. Conditions can decide a claim. Some covers depend on plans being obtained and CAT and Genny being used.
  4. HSG47 is the benchmark. Insurers judge your digging procedure against HSE guidance on avoiding underground services.
  5. Evidence beats explanation. Records of plans, scans, permits and training carry more weight than assurances.

What counts as a cable or utility strike claim?

A cable or utility strike claim arises when your work damages buried or concealed apparatus belonging to someone else, such as electricity cables, gas or water pipes, or another operator's fibre and duct. The asset owner may claim repair costs and, depending on the circumstances, other losses. Injury claims can follow where live services are struck.

Strikes happen during excavation, moling, coring, drilling and rodding. The claim may arrive months later, and the excess and policy wording decide how much falls on you.

How do underground services exclusions and excesses work?

Contractor liability policies treat buried services in different ways. Some exclude the damage altogether, some cover it only with an underground services extension, and many apply a separate, higher excess to each strike. Cover can also depend on conditions such as obtaining plans and using locating equipment, so the exact wording matters.
ApproachWhat it means for you
Full exclusionNo cover for damage to underground services. Unsuitable for anyone who digs.
Extension with conditionsCover applies only if set precautions are followed, such as plans, scanning and hand digging.
Separate higher excessEach strike carries its own excess, often higher than the standard one.
Sub-limitA lower maximum for underground services than the main liability limit.

After a claim, expect a higher excess or stricter conditions. Failing to meet a condition could leave a future strike uninsured.

What do HSG47, CAT and Genny mean for your insurance?

HSG47 is HSE guidance on avoiding danger from underground services. It sets out planning, locating and safe digging practice. A CAT is a cable avoidance tool and a Genny is the signal generator used with it. Insurers use HSG47 as the benchmark when judging whether your procedures were adequate.

In broad terms, HSG47 expects you to plan using available records, locate and mark services with suitable equipment used by trained people, and dig safely near them, including hand-dug trial holes. CAT and Genny are not guarantees: plastic pipes may not be detected and plans can be wrong, so underwriters look at the whole system. Our guide to street works and civils insurance for fibre rollout covers digging risks in more depth.

Why do permits, plans and records matter?

Records show an insurer, and the asset owner's claims team, that the precautions were actually taken. Without them, it is hard to defend a claim or argue that a condition was met. A simple permit-to-dig system, with plans, scan results and sign-off kept for each job, makes both claims and renewals easier.
  • Utility plans obtained before work starts, with the date requested.
  • A permit to dig, signed by a competent supervisor.
  • CAT and Genny scan records, with operator names and calibration dates.
  • Marked-up photos of service positions and trial holes.
  • Training records for every operative, including subcontractors.

How should you present a cable strike claim to new insurers?

Present it fully, factually and with evidence. Explain what happened, what precautions were in place, what your investigation found and what you have changed. Never leave a claim off a proposal: non-disclosure can lead to a policy being voided. A broker can package the facts so underwriters can assess them quickly.
  1. Describe the incident. Date, location, service struck, type of work and who was involved.
  2. Show the precautions. Plans, scans, permits and the method used at the time.
  3. Explain the cause. For example, an unrecorded service or a missed step in the procedure.
  4. Set out the outcome. Claim status and any amount paid or reserved, as confirmed by your insurer.
  5. Evidence the improvements. Retraining, new equipment, revised procedures and supervision checks.

If your previous insurer cancelled or declined, our guides to insurance cancelled by an insurer and business insurance with a claims history explain the next steps, and policy voided for non-disclosure shows why full disclosure matters.

What improvements help you get cover again?

Practical, documented changes help most: refresher CAT and Genny training, a written permit-to-dig procedure, closer supervision of new starters and subcontractors, and regular audits. Accepting a higher excess for a period can also open markets. Each change should address the cause of the original strike.

A clean record usually brings terms back towards normal over time. Our fibre and telecoms contractor insurance page explains the wider programme, and the Insurability Framework™ shows how we rebuild difficult risks. Splicing firms working in chambers should also read our fibre splicing and jointing subcontractor guide.

Frequently asked questions

Usually not. Strikes are common in telecoms and civils work. Specialist and Lloyd's markets will often consider the risk if you can explain what happened and show improvements, although terms may be tighter at first.

Insurers often raise it after a strike claim to share more of the cost of future strikes. Claim-free years and improved procedures can help bring it down.

Yes. Disclose all claims the proposal asks about, whatever the outcome. You can explain the circumstances, but leaving a claim off could invalidate cover.

No. Using locating equipment may be a condition of cover, but the full policy terms still apply. Keep records of scans and training so you can show the condition was met.

HSG47 is HSE guidance on avoiding danger from underground services. It covers planning, locating services and safe digging practice, and insurers use it as a benchmark for contractor procedures.

No. Vans and other road vehicles are insured separately under motor policies.

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.
