How Long Can a Car Insurance Claim Stay Open in the UK?

By Alice T · ClaimPilot editorial team

You reported an accident, the insurer opened a claim, and weeks — maybe months — went by. You've chased, they've promised, the file is still "open". So how long can this actually last? There's no legal cap on the day count, but there are hard rules on how a UK insurer must behave while a claim is open, and a strict clock on when you lose your right to escalate. This guide explains what "open" really means, the timelines that apply, and how to move a stalled claim towards a decision.

The short answer

• There's no fixed maximum on how long a car insurance claim can stay open in the UK. A claim stays open until the insurer settles it, formally declines it, you withdraw it, or a third-party insurer accepts liability and pays.
• The FCA's ICOBS 8 rules require insurers to handle claims "promptly and fairly" and to settle them promptly once the amount is agreed. A claim left open with no substantive activity is a conduct issue you can complain about.
• Simple own-damage claims (comprehensive repair, no injury, no liability dispute) commonly close within weeks.
• Third-party or split-liability claims typically close in months — quicker if the other insurer accepts liability early, slower if liability is contested.
• Personal injury claims can stay open for one to three years or more, because the medical prognosis has to be stable before the value is agreed.
• You have hard time limits to enforce your rights. Six months to take an insurer to the Financial Ombudsman after their final response, six years to sue on the contract in England and Wales (five in Scotland), and three years to bring a personal injury claim in court from the accident or from the date of knowledge.

"Open", "closed", "settled", "declined" — the words matter

An open claim is one the insurer has recorded but has not yet resolved. That resolution can look like:

• Settled — insurer agreed the payout and paid, or authorised the repair, or covered the third party's loss.
• Declined — insurer refused to pay, either wholly or in part, and issued a decision letter.
• Withdrawn — you asked the insurer to close the file without a payout (common on small windscreen or "notification only" incidents, or when you decide to pay for the damage yourself).
• Closed for inactivity — the file is closed administratively because you stopped responding. This is not the same as settled and it can be reopened.

Only the first two — settled or declined — are true resolutions. If your file is "closed for inactivity" and you still believe the claim is valid, you can normally ask for it to be reopened, and you should insist the insurer treats it as a live claim under the same complaint route.

Also worth naming: an open claim marked "fault pending" or "liability under investigation" is typically priced at renewal as if it's a fault claim until resolved — a real reason to keep pushing rather than accepting an open-ended wait. Our guide on how long a claim stays on car insurance in the UK explains the record side.

What the rules actually say about claim handling speed

There is no statute in the UK that says "an insurer must close a motor claim within X days". What there is:

• The Financial Conduct Authority's Insurance Conduct of Business Sourcebook (ICOBS 8.1) requires insurers to handle claims promptly and fairly, provide reasonable guidance to the policyholder, not unreasonably reject a claim, and settle claims promptly once the amount is agreed.
• The FCA's fair value and consumer duty rules apply to the whole claims journey — insurers must act to deliver good outcomes for retail customers, which explicitly includes timely resolution.
• The Insurance Act 2015 governs what an insurer can rely on to decline; it doesn't set claim-handling timeframes, but it limits the grounds on which a claim can be held up.
• The Consumer Insurance (Disclosure and Representations) Act 2012 (CIDRA) governs disclosure at inception, not claim handling, but insurers sometimes reopen disclosure questions during a claim — which is a common cause of long delays.

None of this gives you a stopwatch. All of it gives you the vocabulary to complain when a claim drifts.

Typical open-claim timelines in the UK motor market

These are patterns, not promises — the actual duration turns on liability, the type of loss, and how quickly evidence lands.

• Own-damage comprehensive claim, no injury, no liability dispute: weeks, not months, from notification through engineer's assessment to repair or write-off payment.
• Third-party claim with the other insurer accepting liability early: repairs authorised in weeks; hire car / uninsured losses recovered over one to three months.
• Split-liability or disputed-fault claim: three to twelve months while insurers exchange evidence.
• Personal injury under the Official Injury Claim (OIC) portal: several months for straightforward soft-tissue cases below £5,000.
• Personal injury above the OIC limit: commonly 12–36 months, because the medical prognosis has to stabilise before final valuation.
• Uninsured or untraced driver claims through the Motor Insurers' Bureau: typically months, sometimes longer.

If your claim is materially outside these bands with no explanation, that's a signal — not proof — the file has stalled.

Why claims stay open longer than they should

Common causes, in the order you're likely to meet them:

1. Liability is disputed. Your insurer and the third-party insurer haven't agreed who was at fault. Nothing else moves until that's resolved.
2. Evidence is missing. Police references, dashcam footage, engineer's reports. Insurers often wait for the other side rather than chasing.
3. The injury isn't stable. In PI claims, the medical expert needs to say the prognosis is settled before a final offer.
4. A subrogated recovery is running. Your insurer paid out and is recovering from the other insurer; your file stays open until they get paid.
5. A CIDRA / non-disclosure question was raised mid-claim. The insurer has paused while it checks the original application.
6. Staff churn or admin drift. The unglamorous cause — claims handler changed, chase emails went to a dead inbox.

The first five are legitimate reasons a claim can properly stay open for months. The sixth is not, and the ICOBS 8 handling standard exists precisely for cases like it.

What to do when your claim has been open too long

A staged approach, in this order:

1. Ask for a written status update and a target date. Not "any update?" but: "Please confirm in writing the current status of claim reference [X], the specific action awaited, who owns that action, and the target date for the next decision." Insurers respond differently to specific written requests than to phone chases.

2. Ask for a subject access request under UK GDPR if you suspect the file is not being worked. You are entitled to see the correspondence, notes and evidence held on your claim. This concentrates minds.

3. Raise a formal complaint under the insurer's complaints procedure, using the words "formal complaint about claim handling under ICOBS 8". The FCA requires the insurer to send an acknowledgment within days and a final response within eight weeks. If the eight weeks pass without a final response, or you receive one and disagree, escalate.

4. Escalate to the Financial Ombudsman Service (FOS). You have six months from the date of the insurer's final response letter to refer the case, and generally within six years of the event or three years of when you knew (or should have known) of the problem. FOS is free to consumers and its decisions bind the insurer if you accept them.

5. Consider court proceedings for the contract claim. In England and Wales the limitation period is six years from breach for a simple contract claim, and three years from the date of the accident or from the date of knowledge for personal injury. In Scotland the contract limit is five years. Court is a last resort and worth taking legal advice on — but the clock is real. Our guide to documenting an insurance claim covers the paper trail you'll want if it gets that far.

If the file was declined rather than stalled, take the appeal route: our guide on appealing a rejected UK insurance claim walks through appeal, complaint and FOS steps in order. If you'd rather not do the chase yourself, ClaimPilot can pursue an open motor claim on your behalf — written status requests, formal complaint drafting, FOS escalation and the paperwork to reopen an administratively closed file.

What a long-open claim does to your renewal

While a claim is open, most insurers treat it as fault pending until liability is resolved. Your renewal is likely priced as if it were a fault claim, your No Claims Discount is usually stepped back provisionally (protected NCD shields the discount, not the base premium), and the standard quote-form question — "any claims or incidents in the last five years?" — must be answered "yes", because "open" counts.

If the claim later closes non-fault, go back to the insurer that repriced you and ask them to recode the claim and refund the difference. That request has to be made; it isn't automatic. Keep the settlement letter.

FAQ

Is there a legal maximum time a UK insurer can leave a car insurance claim open? No. There is no statutory limit on claim duration. The FCA's ICOBS 8 rules require prompt, fair handling, and the Financial Ombudsman can order redress if that standard is breached — but there is no single "you must close within X days" rule.

How long does a UK insurer have to respond to a complaint about a stalled claim? Under FCA DISP rules, insurers must send a prompt written acknowledgment and issue a final response within eight weeks. If they miss that deadline, or you disagree with the response, you can refer the complaint to the Financial Ombudsman Service.

How long do I have to sue an insurer for a car insurance claim in the UK? For a breach-of-contract claim on an insurance policy, the limitation period is six years from the breach in England and Wales, five in Scotland. For a personal injury claim in court, it's three years from the accident or from the date of knowledge of the injury. These are backstops — most claims resolve well inside them, but the clock is real.

What if my insurer closed my claim as "inactive" but I never agreed? Ask in writing for the file to be reopened, cite ICOBS 8 handling standards, and log a formal complaint if they refuse. An administrative closure is not a settlement or a decline, and it should not be treated as either.

Does an open claim have to be declared when I switch insurer? Yes. Standard quote-form questions ask about claims and incidents in the last five years, "regardless of fault" and regardless of whether the file is open or closed. Under CIDRA 2012, a "no" that should have been "yes" is a misrepresentation and can be used to void the policy later.
