Claims Cooperation Clauses Explained
Reviewed by Matthew Bartlett, Director, Apex Insurance Brokers Limited · Last reviewed 2026-08-05
Most liability policies — professional indemnity, directors' and officers', public and employers' liability — contain a claims cooperation clause. It sits quietly in the conditions section until the day something goes wrong, and then it governs almost everything you do. Get it right and your insurer steps in to defend you. Get it wrong and you can hand the insurer grounds to reduce or decline an otherwise valid claim.
This guide explains what the clause actually requires of you, how it differs from a claims control clause, and the practical steps that keep you the right side of it.
What a claims cooperation clause requires
The wording varies by insurer, but the core obligations are consistent across the UK market. In broad terms, the clause asks you to:
- Notify promptly. Tell your insurer as soon as you become aware of a claim — and usually of any circumstance that might give rise to one — within the timeframe stated in the policy.
- Not admit liability. Do not admit fault, make an offer, or agree to settle or pay without your insurer's written consent.
- Preserve evidence. Keep relevant documents, correspondence, files and physical evidence intact rather than destroying or altering them.
- Provide information. Give your insurer the details, documents and statements it reasonably requests, honestly and without delay.
- Assist the defence. Cooperate with the insurer, its solicitors and loss adjusters — attend meetings, help take witness statements and support the conduct of the claim.
- Take reasonable steps to mitigate. Act to limit the loss where you sensibly can, rather than letting it worsen.
These duties are practical, not onerous. The insurer is funding your defence and carries the financial risk of the outcome, so it needs early sight of the facts and a free hand to manage the matter sensibly.
Why the clause matters: conditions precedent
Not every claims condition carries the same weight. Some are drafted as a condition precedent to liability, meaning the insurer's obligation to pay only arises if you have complied. Notification clauses in particular are often conditions precedent. Breach one and the insurer may be entitled to decline the claim outright — even if the underlying claim against you is genuine and covered.
The Insurance Act 2015 reshaped parts of this landscape but did not abolish conditions precedent. It did, however, limit the effect of breaching terms that are designed to reduce the risk of a particular type or timing of loss: an insurer generally cannot rely on such a breach if you can show the breach could not have increased the risk of the loss that actually occurred. Late notification of a claim, though, frequently does prejudice the insurer, so the practical safest course is simple — notify early and cooperate fully.
A note on notification: "As soon as reasonably practicable" and "within 30 days" are not the same test. Always check whether your policy sets a fixed deadline, and diarise it the moment a circumstance surfaces. Many valid claims are lost purely on timing.
Cooperation clause vs control clause
The two are easy to confuse but grant very different levels of authority. A claims cooperation clause obliges you to work with the insurer while you generally retain conduct of the claim. A claims control clause goes further, handing the insurer the right to take over and control the investigation, defence and settlement entirely.
| Feature | Claims cooperation clause | Claims control clause |
|---|---|---|
| Who conducts the claim | Usually the insured, with the insurer's involvement | The insurer takes full control |
| Your duty | Cooperate, inform and assist | Cooperate and defer to the insurer's decisions |
| Settlement authority | Not without insurer consent | Insurer decides |
| Common in | Many liability and PI policies | Reinsurance and some specialty covers |
If you are unsure which applies to you, check your schedule and wording — or ask your broker to confirm. It changes who is in the driving seat once a claim lands.
Practical steps when a claim arises
When a letter of claim, a complaint or a worrying circumstance lands on your desk, work through these steps:
- Stop and do not respond substantively. Acknowledge receipt if you must, but do not admit anything or make an offer.
- Notify your broker or insurer the same day. Put it in writing and keep proof of the date.
- Gather the file. Assemble the contract, correspondence, notes and any evidence, and preserve it exactly as it is.
- Route all contact through your insurer's team. Once solicitors or adjusters are appointed, let them lead on communication with the claimant.
- Keep cooperating. Respond to information requests promptly and honestly throughout the life of the claim.
The single most valuable thing you can do is tell someone early. A five-minute call to notify a circumstance protects cover in a way that no amount of later argument can.

Common questions
Can my insurer refuse a claim if I admit liability?
Potentially, yes. Most cooperation clauses prohibit admitting liability or settling without consent, so an unauthorised admission can prejudice your insurer and give grounds to reduce or decline the claim. If a claimant presses you, say only that you are passing the matter to your insurer.
What counts as a "circumstance" I need to notify?
A circumstance is any event or awareness that might reasonably lead to a claim — for example a client complaint, a mistake you have spotted, or a threat of legal action — even before a formal claim is made. Notifying circumstances during the policy period protects cover, so when in doubt, tell your insurer.
Does the Insurance Act 2015 protect me if I breach a claims condition?
To a degree. The Act limits an insurer's ability to rely on a breach of certain risk-mitigation terms where the breach could not have increased the actual loss. It does not, however, remove all notification deadlines or conditions precedent, so the reliable approach is still to notify promptly and cooperate fully.
