What Is a No-Claims Bonus?

If you have ever insured a car, you will have seen it on the quote: a "no-claims bonus" or "no-claims discount" that quietly knocks money off your premium for every year you have driven without claiming. It is one of the most valuable features in motor insurance — and one of the most misunderstood. People are unsure how it builds, what happens if they have a bump, and whether paying to "protect" it is money well spent. This guide explains the no-claims bonus in plain English, including how much it can save and the catch that surprises many drivers when they finally do claim.

This article is general information about no-claims bonuses, not financial advice. The exact rules, percentages and protection terms vary between insurers, so always check your own policy.

What a no-claims bonus is

A no-claims bonus (NCB), also called a no-claims discount, is a reduction in your insurance premium that you earn for each consecutive year you go without making a claim. It is most common in car insurance, though similar discounts exist on some other policies.

The logic is simple: insurers price on risk, and a driver who has gone several years without claiming looks, statistically, like a safer bet than one who claims often. The NCB rewards that record with a discount that grows over time, giving you a financial incentive to drive carefully and to think twice before making small claims.

Crucially, the NCB is yours — it follows you, not the car or the insurer. When you switch providers, you can carry your earned years across, usually by providing proof from your previous insurer.

How it builds up

You earn one year of no-claims bonus for each full policy year in which you make no claim that affects it. The discount climbs step by step, and the percentage saving typically rises with each claim-free year before levelling off at a maximum — often after around five or more years.

The exact figures vary by insurer, but the shape looks something like this:

By the time you reach the maximum, a no-claims bonus can take a large slice off your premium — which is exactly why it is worth understanding and guarding. It rewards the same patient, long-term thinking that pays off elsewhere in personal finance, much like the way compound interest rewards leaving savings untouched.

Your no-claims bonus is one of the biggest long-term savings in motor insurance. Treat the years you have built up as an asset worth protecting.

What happens when you claim

This is where many drivers get caught out. Making a claim can reduce or reset your no-claims bonus — but not every claim does, and not by the same amount.

• At-fault claims (or any claim where the insurer cannot recover its costs) usually cut your NCB. Depending on the policy, several years of bonus can be lost from a single claim.
• Non-fault claims where your insurer recovers everything from the other side may leave your NCB untouched, because the cost ultimately falls on the at-fault party's insurer.
• Some specific claims, such as a glass-only windscreen claim, may not affect the bonus at all, depending on the policy wording.

Because an at-fault claim can wipe out years of accumulated discount, the true cost of a small claim is not just the excess — it is the excess plus the higher premiums you will pay for years afterwards as your bonus rebuilds. That is why a minor prang is sometimes cheaper to pay for yourself. Before you decide, it is always worth understanding how the claims process works and how a particular claim would be treated.

Protecting your no-claims bonus

For an extra fee, most insurers let you protect your no-claims bonus. This caps how far your bonus can fall: typically, a set number of claims within a period will not reduce your accumulated NCB.

It sounds like a guarantee against rising costs, but there is an important catch that often surprises people:

• *Protection preserves your discount, not your premium.* Even with a protected NCB, your insurer can still re-rate you as a higher risk after a claim, so the base premium the discount is applied to can rise. In other words, protection stops you losing the bonus years, but it does not freeze the total price you pay.

Whether protection is worth it depends on the size of your premium, how big your bonus is, and how likely you think you are to claim. For a driver with a large maximum bonus and a high premium, protecting it can make sense; for someone with a small bonus, the extra cost may not be justified. It is a judgement call, and a sensible one to weigh as part of understanding car insurance overall.

Common misunderstandings

A few points trip people up:

• One bonus, one policy. You generally cannot use the same NCB on two cars at the same time; it is tied to a single vehicle and policy.
• It can expire. If you go without insurance for a long period (for example, you stop driving for a couple of years), some insurers may no longer recognise the bonus, so check the time limits.
• Named-driver experience is different. Being a named driver may help you in other ways, but it is not the same as building your own no-claims bonus as a policyholder.
• Honesty matters. Always declare claims accurately when asked; insurers check, and misrepresentation can void cover.

The bottom line

A no-claims bonus is a discount you earn for each consecutive claim-free year, and over time it becomes one of the most valuable parts of your insurance — capable of cutting a premium substantially once it reaches the maximum. The flip side is that an at-fault claim can erase years of it, so the real cost of claiming includes the discount you lose, not just the excess you pay. Protecting your bonus caps that loss but does not stop your premium rising, so weigh the extra fee against your own circumstances.
