How the No-Claim Bonus Works (and How to Protect It)

A no-claim bonus, sometimes called a no-claim discount, rewards you with a lower car insurance premium for each year you do not claim. It builds up over time, recognising that a claim-free driver is a lower risk. Understanding how it works helps you protect it and avoid throwing away years of savings on a small claim.

How it works

Each claim-free year, your insurer applies a growing discount to your premium. The longer you go without claiming, the larger the discount can become, up to the insurer's maximum. Make a claim, and the bonus can be reduced or reset, which pushes your premium back up. Every insurer structures this differently, so ask how yours works.

How to protect it

• Do not claim for small amounts you could comfortably pay yourself. If a repair costs close to your excess, claiming may cost you more in lost bonus than you gain.
• Ask about bonus protection. Some insurers let you protect your no-claim bonus for an extra premium, so one claim does not wipe it out.
• Drive carefully and secure your car to avoid claims in the first place.

Does it transfer if you switch insurers?

Sometimes. Some insurers recognise your claim-free history from a previous insurer, while others rate you fresh. If you are thinking of switching, ask the new insurer whether they will honour your record before you move, and keep proof of your claim-free years.

Is it worth chasing?

A no-claim bonus is valuable, but it should not stop you claiming for a genuine, larger loss, that is what insurance is for. The trick is to self-fund the small stuff and claim the big stuff. Our how to lower your premiums guide covers this balance.

The bottom line

A no-claim bonus quietly lowers your premium the longer you stay claim-free, so protect it by skipping small claims and asking about bonus protection. When you compare cover, ask how each insurer treats your claim-free history. Get a car insurance quote and compare.
