Your no claims bonus is worth real money, so if you are taking a break from driving, selling your car or switching to a partner’s policy, one question matters: does no claims bonus expire? The short answer is that it can. A no claims bonus does not last forever once you stop holding a policy in your own name, and the time limit varies between insurers. This guide explains how the expiry works in the UK, how to check what you have, and how to avoid losing a discount you spent years building.
What a No Claims Bonus Actually Is
A no claims bonus (NCB), sometimes called a no claims discount, is the reduction insurers give you for each consecutive year of claim-free driving under a policy in your own name. The discount grows year by year up to a maximum set by each insurer, and it can reduce a premium substantially. Because the bonus belongs to you as the policyholder rather than to the car, you can move it between vehicles and between insurers, provided you can prove it. If you are new to the concept, our beginner’s guide to how car insurance works in the UK explains where the bonus fits into the price you pay.
Does No Claims Bonus Expire? The Typical Rule
With most UK insurers, a no claims bonus remains valid for around two years after your last policy ends. If you start a new policy within that window, you can usually apply the bonus in full. Leave it longer than the insurer’s limit, which is commonly two years but is not identical everywhere, and the bonus lapses: you start again from zero years, as if you were a new driver.
There are a few important qualifications:
- The limit runs from the end date of your last policy, not from when you stopped driving.
- Some insurers set a shorter or longer window, so always check the specific insurer’s terms before relying on the two-year figure.
- Bonus earned on a policy held abroad or on a company car scheme may be treated differently and may need extra evidence.
How to Prove Your No Claims Bonus
When you take out a new policy, the insurer will ask for proof of your bonus. The standard evidence is the renewal invitation or cancellation letter from your previous insurer, which states the number of years earned and the policy end date. Keep that document somewhere safe whenever a policy ends; insurers can usually reissue it, but requests take time, and time is exactly what an expiring bonus does not have. If your proof shows a gap in cover, expect questions: insurers want to confirm the bonus is still within its validity window.
Protected No Claims Bonus: What It Does and Does Not Do
Many insurers let you pay extra to protect your bonus once you have built up several years. Protection means that one or two claims within a set period will not reduce the number of bonus years you hold. It does not freeze your premium: your price can still rise after a claim because the claim itself changes your risk profile. Protection also does nothing to stop expiry. If you stop insuring altogether, the clock still runs, protected or not.
Common Ways People Lose Their Bonus
- A long gap without a policy. Working abroad, relying on public transport or being a named driver on someone else’s policy for several years is the most common cause.
- Being only a named driver. Named drivers do not usually earn their own bonus on someone else’s policy, though some insurers offer introductory discounts for named-driver experience.
- Letting proof documents go missing. Without evidence, a new insurer may refuse the bonus even if it is technically still valid.
- Assuming a partner’s bonus is shared. A bonus belongs to one policyholder. Couples with one car and one policy build one bonus, not two.
Some of the same factors that put a bonus at risk also push prices up generally; our article on why car insurance is so expensive in the UK explains the wider picture, and our guide to fully comprehensive car insurance shows how the level of cover interacts with your discount.
How to Keep Your Bonus Alive During a Break
If you expect a gap of more than a few months, plan for the expiry date rather than discovering it later. Options include insuring a cheap runabout in your own name to keep the policy line unbroken, checking whether an insurer will accept bonus that is slightly older in return for evidence of recent driving, and diarising the two-year anniversary of your last policy end date so you act before it passes. If you are returning to driving after a break, compare quotes widely: insurers treat returning drivers very differently, and a difference in how they view your lapsed bonus can be worth a significant sum. Drivers hiring a car in the meantime should note that hire arrangements never build bonus; our guide to rental car insurance in the UK explains how that cover works instead.
The Bottom Line
So, does no claims bonus expire? Yes, in practice it does: most UK insurers will only honour it for about two years after your last policy ends, and after that the years you earned are gone. The defence is simple: keep your proof documents, note the date your last policy ended, and restart a policy in your own name before the window closes if you plan to drive again. A bonus takes years to build and one missed deadline to lose, so it is worth a diary entry.
