Gas Safety and Your Insurance: Why a Missing CP42 Can Void Your Claim

Your gas safety certificate probably isn't mentioned anywhere in your insurance policy. That won't stop your insurer from using it to refuse your claim.

Most UK commercial insurers don't individually list the CP42 as a named condition in their base wordings. Operators read this as irrelevant to their cover. Insurers enforce gas safety compliance through three separate mechanisms, and any one of them can be grounds for refusing a claim.

The three routes to a denied claim

The reasonable precautions clause. Present in every commercial policy wording we examined, this clause requires you to comply with your statutory obligations. The Gas Safety (Installation and Use) Regulations 1998 require maintenance of gas appliances in workplaces. A lapsed CP42 is evidence that you haven't met that obligation. Your insurer doesn't need to mention gas safety by name: the reasonable precautions clause imports the statutory obligation wholesale.

RSA (now Intact) is among the most prescriptive major insurers for hospitality businesses. Their kitchen equipment conditions cover thermostat servicing and ducting cleaning, and their enforcement clause is explicit: "Where material to the loss, failure to comply with any of these requirements will result in Us not paying Your Property Damage claim." Zurich takes the broadest approach, with a clause that makes all policy terms conditions precedent to liability.

Your Statement of Fact. When you took out the policy, you or your broker declared what compliance certificates you held and what maintenance schedules you followed. If those answers assumed a current gas safety certificate and you don't have one, the factual basis of your cover is wrong. Under the Insurance Act 2015, an insurer can avoid a policy entirely if the misrepresentation was deliberate or reckless, or adjust the terms to reflect what they would have offered had they known the truth.

In Financial Ombudsman decision DRN-4521043, HDI voided a food business's policy after a fire because the cover had been bought on wrong answers about electrical testing and kitchen duct cleaning. The complaint was not upheld. The ombudsman found the insurer was entitled to treat the policy as void.

Bespoke risk survey conditions. After a property survey, insurers impose specific compliance requirements that become binding on your individual policy. These conditions appear in your policy schedule or endorsements, not in the base wording your broker might have summarised for you. The loss adjuster asks for the certificate. If you can't produce one, the endorsement gives the insurer its answer.

How this plays out in practice

Court cases and Financial Ombudsman decisions follow a consistent pattern. After an incident, you file a claim and the loss adjuster asks for your compliance paperwork. If the paperwork is missing or doesn't match what you declared at underwriting, the insurer invokes one of the routes above.

In Zurich v Coralpeak Ltd [2016] CSOH 43, fire destroyed a Glasgow school and Zurich refused to pay, arguing the insured had breached the reasonable precautions clause by failing to act on fire risk assessments. The court held the clause was a condition precedent, and that the cause of the fire would not matter once a breach was proved. Whether the clause had actually been breached was left for a further hearing.

In Cuckow v AXA [2023] EWHC 701, failure to retain and produce documentation required under the policy breached conditions precedent, and AXA got a complete defence. In Bluebon Ltd v Ageas [2017] EWHC 3301, a hotel was destroyed by fire. The electrical inspection warranty hadn't been satisfied. Cover was suspended for the entire period of non-compliance.

These cases involved fire risk assessments, electrical certification, and installation paperwork, not gas safety certificates. No published gas-specific claim dispute has reached the courts. But the contractual mechanism is the same: a reasonable precautions clause or a compliance warranty operates identically whether the missing document is an EICR or a CP42.

When the Insurance Act 2015 won't help you

Section 11 of the Insurance Act 2015 limits an insurer's ability to rely on a breach to deny a claim if the non-compliance "could not have increased the risk of the loss which actually occurred." A lapsed gas certificate can't be used to deny a flood claim or a theft claim. The breach and the loss must be connected.

For gas-related losses, this protection is unlikely to help. If the claim follows a kitchen fire traced to a faulty appliance or a gas explosion, the connection between a lapsed CP42 and the loss is direct. Section 11 was not designed to protect policyholders in that situation.

Financial Ombudsman decision DRN-3903608 illustrates the distinction. Hubener declined a restaurant fire claim over electrical testing and waste removal conditions. The ombudsman found it unfair to rely on either one: the testing had been done, and the waste played no part in the fire. The claim had to be reconsidered without those conditions. The line between protection and exposure turns on one question: does the lapsed paperwork connect to what actually went wrong? If your missing gas certificate contradicts your original Statement of Fact, the insurer can pursue a fair-presentation remedy regardless of whether the breach caused the loss. Section 11 only helps when the breach is genuinely unconnected.

The broker gap

Your broker probably didn't check your CP42. Most brokers operate on a declaration basis. They ask questions on proposal forms and rely on your answers. They don't verify original documents or chase renewals.

This creates a gap that only surfaces at claim time. You obtain cover while unknowingly breaching its conditions. Nobody checks until a loss adjuster starts asking for paperwork.

Specialist hospitality underwriters work differently. NBS Underwriting builds compliance into quoting: they require EICR status, fire alarm type, food hygiene rating, and extraction cleaning frequency before they'll price a policy. If you don't know which type of underwriter backs your policy, ask your broker. The answer determines how exposed you are.

Where the exposure surfaces

Expired CP42 certificates (more than 12 months old, the interval insurers and engineers work to) are a common trigger. The distinction the courts have drawn in the cases above runs along one line: voluntary disclosure of a lapse, made before a claim, is treatable as a fair-presentation correction under the Insurance Act 2015. Misrepresentation discovered during a claim is not.

Bespoke conditions imposed after a risk survey appear in policy schedules and endorsements, separate from the base wordings brokers typically summarise. Loss adjusters enforce them independently of whether the policyholder has read them. Statements of Fact made at underwriting bind the policy to the compliance picture declared; any answer that assumed a current certificate no longer held is the kind of misrepresentation Section 11 does not cure.

The evidentiary point is the certificate itself, with the Gas Safe registration number of the signing engineer. In Cuckow, the documents had once been in the insured's hands. They were lost or disposed of, and when the insurer asked for them, nobody could produce what the policy required.

A CP42 starts at around £150, and costs more for multi-appliance kitchens. In a Fire Protection Association analysis of 4,782 major UK fires between January 2009 and December 2019 where the loss reached at least £100,000, the mean loss was £657,074. A denied claim on that scale is not a fine; it is the full cost of the loss, uninsured. Loss adjusters ask for the certificate before the insurer pays out.
