Being involved in a car accident is stressful enough without worrying about your insurance. But what actually happens to your policy, your premiums and your no claims bonus once a claim is made? This guide walks you through everything you need to know, from how fault is decided to what you can do to keep costs down after an accident.
Quick Summary
In This Guide
A fault claim is one where your insurer pays out and cannot recover the full costs from another party. A non-fault claim is one where your insurer recovers all costs from whoever was responsible. This distinction is important because it directly affects your no claims bonus and your future premiums.
It is worth knowing that the word "fault" here does not always mean you caused the accident. If another driver hits you but drives off without leaving their details, your insurer has nobody to recover costs from. That means the claim is recorded as a fault claim on your record, even though you did nothing wrong.
| Scenario | Claim Type | Effect on NCB |
|---|---|---|
| Another driver hits you and their insurer accepts full liability | Non-fault | NCB should not be affected |
| You cause an accident and your insurer pays out | Fault | NCB will be reduced or lost |
| You hit an animal on the road and claim for repairs | Fault | NCB will be reduced or lost |
| Your car is damaged by an unidentified driver (hit and run) | Fault | NCB will be reduced or lost |
| Both drivers are partly to blame (split liability) | Fault (partial) | NCB may be reduced |
| Windscreen chip repaired under comprehensive cover | Usually excluded | NCB should not be affected |
If you are unsure about the difference between cover levels and how they affect what you can claim for, our guide to third party vs fully comprehensive insurance explains everything in plain English.

Always tell your insurer about any accident you are involved in, even if you do not plan to make a claim. Failing to disclose an incident can invalidate your policy and could mean a future claim is rejected. For more on what can go wrong, read our guide on what to do if your car insurance claim is rejected.
There is no single figure for how much your car insurance goes up after an accident. The increase depends on several factors, including whether the claim was your fault, how much the insurer paid out, the severity of any injuries, your overall driving history and your insurer's own risk model. A fault claim can lead to a significant premium increase, but the exact amount will vary from driver to driver and insurer to insurer.
Non-fault claims can also nudge your premium up, although the impact is usually much smaller. Insurers look at statistical patterns and find that drivers who have been involved in any kind of accident are more likely to be involved in another one in the future, even if they were not to blame. That said, a single non-fault claim is unlikely to have a dramatic effect on what you pay.
The size of the claim matters too. A minor bump with a small repair bill will have less impact on your next renewal than a serious collision involving injury payouts. According to the ABI, UK motor insurers paid out £11.9 billion in claims during 2025 across 2.5 million claims, with vehicle repairs accounting for 63% of that total. Repair costs have been rising steadily because modern cars are packed with sensors, cameras and electronics that are expensive to fix or replace.
ABI - Motor Insurance Claims Data, Feb 2026To understand what the average UK driver is currently paying and how that has changed, take a look at our guide to car insurance costs in 2026.
Why Are Repair Costs So High?
Modern vehicles are fitted with advanced systems, sensors and cameras that make even minor repairs more specialised and costly. A simple wing mirror replacement now involves actuators, motors, lights and sensors. The ABI reports that vehicle damage repairs totalled nearly £7.5 billion in 2025, and a shortage of skilled technicians is adding further pressure to repair times and costs.
ABI - Motor Insurance Claims Data, Feb 2026Your no claims bonus (NCB) is a discount you earn for every year you drive without making a fault claim. It is one of the most valuable tools for keeping your car insurance affordable. According to the ABI, a five-year no claims bonus can reduce your premium by up to 60%.
ABI - No Claims Bonuses and DiscountsIf you make a fault claim, you will typically lose some or all of your no claims bonus. How much you lose depends on your insurer and the number of years you have built up. Some insurers reduce your bonus by two years per fault claim, while others may reset it entirely.
| Years of NCB | What Happens to Your Discount |
|---|---|
| 0 years | No discount - you pay the full premium |
| 1 year | Discount of up to 30% |
| 2-4 years | Discount increases each claim-free year - exact percentages vary between insurers |
| 5+ years | Discount of up to 60% - most insurers cap the maximum between 5 and 9 years |
If you make a non-fault claim, your no claims bonus should not be permanently affected, provided your insurer is able to recover all costs from the other party. However, your NCB may be temporarily reduced while the claim is being investigated. Once liability is confirmed and costs are recovered, your full bonus should be restored.
No claims bonus protection is an optional add-on that usually costs between £20 and £60 per year. It allows you to make one or two claims within a set period, typically three to five years, without losing the discount you have built up. Most insurers only offer protection once you have at least four years of no claims.
ABI - No Claims Bonuses and DiscountsThere is one important thing to understand: NCB protection only preserves your discount percentage. It does not freeze your overall premium. After a fault claim, your base premium may still increase because insurers see you as a higher risk. But the discount is still applied on top of that new base price, so the increase is less severe than it would be without protection.
For a full breakdown of whether NCB protection makes financial sense for your situation, read our guide on no claims bonus protection.
Most car insurance claims stay on your record for five years. During that time, the claim can affect the price you are quoted when you renew or switch insurer. Most insurers ask you to declare any claims from the past five years when you apply for a new policy, although some may ask about a three-year window.
The good news is that the impact of a claim tends to fade over time. A claim from four years ago will usually have less effect on your premium than one from last year, assuming you have not been involved in any further incidents. Keeping a clean record after an accident is the single most effective way to bring your premiums back down.
Brumble Top Tip
When comparing car insurance quotes, always declare all claims within the period your insurer asks about. If they discover undeclared claims through the CUE database, your policy could be invalidated and future claims rejected.
The Claims and Underwriting Exchange (CUE) is a central database run by the Motor Insurers' Bureau (MIB) where UK insurers record details of incidents reported to them. It holds around 34 million records covering motor, home, travel and personal injury insurance. Every incident you report to your insurer is logged on CUE, whether or not it resulted in a claim.
Motor Insurers' Bureau (MIB) - CUEWhen you apply for car insurance or make a claim, your insurer can check your history on CUE. This means they can see any previous claims, reported incidents and how much was paid out. If the information you provide when getting a quote does not match what is on CUE, your insurer may increase your premium, reject your application or even invalidate your policy.
CUE records are kept for six years from the date a claim is closed. This is slightly longer than the five years most insurers ask about, so there can be occasions where an older incident is still visible on the database even if you are no longer required to declare it. For a full list of the key terms you will come across when dealing with insurers, our car insurance glossary breaks everything down in simple language.
Motor Insurers' Bureau (MIB) - CUENot always. Whether it is worth making a claim depends on the cost of the damage, your excess and the potential impact on your premiums and no claims bonus. In some cases, it can be more cost-effective to pay for repairs yourself.
For example, if the repair cost is close to or only slightly above your excess, claiming may not give you much financial benefit. You would still pay the excess, and the claim would sit on your record for five years, potentially pushing up your premiums at every renewal during that period.
| Situation | Claiming May Be Worth It | Paying Yourself May Be Better |
|---|---|---|
| Repair cost vs excess | Repair costs significantly more than your excess | Repair costs close to or just above your excess |
| NCB at risk | You have NCB protection or a short bonus | You have a long unprotected bonus worth hundreds |
| Third party involved | Another party is injured or their vehicle is damaged | Single-vehicle minor cosmetic damage |
| Vehicle write-off | Yes - this is what insurance is for | Not applicable |
Even if you decide not to claim, you must still report the accident to your insurer. Failing to do so could be treated as non-disclosure and may affect your cover. You can tell your insurer you are reporting the incident "for information only" and that you do not wish to make a claim.
Knowing what to do immediately after a car accident can protect your safety, your legal position and your insurance claim. Here is a step-by-step guide to follow at the scene and in the days afterwards.
What If the Other Driver Is Uninsured?
If you are hit by an uninsured driver, check whether your policy includes an "uninsured driver promise". Many comprehensive policies will waive your excess and protect your no claims bonus in this situation. If not, you can contact the Motor Insurers' Bureau (MIB) for help with compensation. The MIB exists to support victims of uninsured and untraced drivers.
Even after an accident, there are practical steps you can take to bring your car insurance costs back down. None of these are quick fixes, but together they can make a real difference over the following months and years.

Compare Car InsuranceDoes car insurance go up after an accident that was not my fault?
It can, yes. Even after a non-fault claim, some insurers increase premiums slightly because statistics show drivers involved in any accident are more likely to claim again. However, the increase is usually much smaller than after a fault claim, and your no claims bonus should not be permanently affected.
How long do I need to declare an accident to my car insurance company?
Most insurers ask you to declare claims from the past five years when applying for a new policy. The CUE database holds records for six years from the date a claim is closed. Always check what your specific insurer asks for, as some may request a shorter or longer declaration period.
Will my insurance go up if I report an accident but do not claim?
It is possible. Even incidents reported "for information only" are logged on the CUE database and may be visible to insurers when you apply for a new policy. However, the impact is usually minimal compared to making a full claim, and not reporting an accident could invalidate your policy.
Can I keep my no claims bonus if someone else was driving my car?
If a named driver on your policy causes an accident and a fault claim is made, your no claims bonus will be affected because the bonus belongs to the policyholder, not the driver. The named driver does not build up their own NCB on your policy either.
Is it worth claiming for minor damage after an accident?
Not always. If the repair cost is close to your excess, it may be cheaper in the long run to pay for it yourself. Making a claim adds it to your record for five years and could push up your premiums at every renewal during that time. Weigh up the repair cost against the potential increase in premiums over several years.
Does a dash cam help with car insurance claims after an accident?
Yes, a dash cam can be very helpful. It provides clear video evidence of what happened, which can speed up the claims process and help prove you were not at fault. Some insurers offer small discounts for drivers who have a dash cam fitted.
What happens to my car insurance if my car is written off?
If your car is written off, your insurer will pay you the market value of the vehicle at the time of the accident, minus any excess. Your policy will then end for that vehicle. The claim will be recorded on your history, and you will need to take out a new policy for your replacement car. Your no claims bonus will be affected if it was a fault claim.
Can I switch car insurance after making a claim?
Yes, you can switch insurer at renewal even if you have a recent claim. In fact, comparing quotes after a claim is one of the best ways to avoid overpaying, as different insurers weigh claims history differently. You must declare the claim to your new insurer, and your current insurer will provide proof of your no claims bonus.
