What is a 'no-claims' bonus or discount?
A no-claims bonus - also known as a no-claims discount - is a percentage discount that your insurer shaves off your insurance premium to reward you for not having made a car insurance claim in the previous year.
So if, for example, you had a no-claims bonus of 30%, you’d pay £700 where you would otherwise have paid £1,000.
For each consecutive year that you don’t make any claims, the discount increases. So your insurer might award you 30% for one year without claims, but five claims-free years under your belt might net you 60%.
No-claims discounts are just one of several ways to get cheap car insurance.
What’s the maximum no-claims bonus I can get?
As you build up more claims-free years, you progress along a no-claims bonus scale, which might look something like the example below.
Eventually, you’ll reach the number of claims-free years required to net the maximum discount your insurer will offer.
How no-claims discounts build up
Each insurer's no-claims bonus scheme is different - from the size of discounts to the number of claims-free years it takes to achieve them.
Maximum discounts range from around 40% to 80%, while the number of claims-free years you need before you’re at the top of the scale ranges from around five to 15 years.

What is a no-claims bonus worth?
By itself, a no-claims bonus doesn’t really say much about how much you’ll pay - you need to know what the premium is to work out how much of a saving it represents.
Suppose there are two insurers. Both have a base premium of £1,000, to which the discount is applied. With insurer A, your no-claims bonus is 75%, and with Insurer B, 60%. In this case, insurer A is clearly the cheapest.
But when the base premiums are different - as they’re likely to be in the real world - the comparison changes. If insurer A’s base premium is £1,500 and Insurer B’s, £900, for instance - then Insurer B is cheaper.
|Insurer A||Insurer B|
|Premium with discount||£250||£400|
|Premium with discount||£375||£360|
Some insurers will make a point of awarding generous no-claims bonuses in their marketing, but it's important to compare the final quote - with any discounts included - to determine which is the best deal. Read our guide on how to find an insurer with a lower premium.
The reason it’s worth keeping your no-claims bonus in mind is that you can lose it if you make a claim, meaning you'll pay higher premiums than you otherwise would have.
How can a claim affect my no-claims bonus?
If you make a car insurance claim, you may lose some of your no-claims bonus according to where you are on the insurer’s ‘step-back’ scale.
This basically bumps the discount back down to what it was in previous years. Insurers have different step-back scales.
In the example below, the driver has spent five years building their no-claims bonus up to 60%.
When they make a claim, that five-year discount reduces to a three-year discount - so at renewal they only get 40% off and have to spend two years building their no-claims bonus back to what it was.
What claims don't affect my no-claims bonus?
There are certain types of claim that won't erode your no-claims bonus. Generally, insurers will leave your no-claims bonus alone if your claim was not a 'fault' claim.
This means they were able to recover their repair costs in full from the party at fault. Similarly, many insurers will disregard non-fault claims where the other driver was uninsured.
It's also quite common for insurers to make exceptions with claims for glass damage.

Should I protect my no-claims bonus?
No-claims bonus protection is an added extra that you can buy with your insurance.
It will prevent a limited number of claims (two or three claims over a three-year period is common) from having an impact on your no-claims bonus.
No-claims bonus protection will certainly save you money if you make a claim. However, you'll need to pay extra for it (around £60 is fairly typical), so its value depends on how much discount you’d stand to lose by claiming.
Insurers don’t make this easy to find out - but they do have to show how much discount, on average, their customers were awarded for each year of no claims.
So this should give you a starting point in working out whether to pay for no-claims bonus protection.
As a general rule of thumb, the bigger your no-claims bonus the more you stand to lose through making a claim, and therefore the greater the value of the protection.
How does no-claims bonus protection work?
A fairly common misconception about bonus protection is that it stops your premiums from rising because of a claim.
Unfortunately, this isn’t true. If you make a claim and, as a result, the insurer thinks you’re more likely to make future claims, it will increase your premium. After this, it will apply whatever discount you have.
So, suppose your discount is 60% and you’re paying £400 instead of the base premium of £1,000. Then you make a claim - protected under the added extra you've paid for.
At the following renewal your insurer could then increase that base premium to £1,300. With the same 60% discount in place, you’d now be paying £520.

Can I transfer my no-claims bonus to a new policy?
Yes. When you apply for car insurance, the insurer will ask and check how much no-claims bonus you’re entitled to.
In some cases, you’ll be asked to supply evidence from your previous insurer to back this up. This allows you to carry over the benefits of your accumulated claims record without having to start from scratch each time you switch insurer.
You’ll not always see perfect continuity, though - as insurers each have their own no-claims bonus schemes and will apply their own rules.
For example, some insurers may not recognise no-claims bonus you’ve accrued as a named driver on someone else’s policy, and if you’ve not been insured for a few years, the previous no-claims bonus will lapse.
Do I need proof of my no-claims bonus?
In many cases, you won’t be asked for proof of your no-claims bonus, but you should always assume that you will and have it in order.
Insurers will often check online databases first to corroborate the no-claims bonus entitlement you've stated in your application.
Your no-claims bonus should also be stated in your paperwork from the insurer you’re leaving.
Where this isn’t available, you can write to your insurer and ask it to supply you with a letter detailing your number of claim-free years.
