How Many Years No Claims Bonus Can You Build? (UK Guide)

How many years no claims bonus can you build depends on your insurer, but most UK providers cap the discount at 9 years. A small number stop earlier, at around 5 years, while others let you keep accumulating up to 15 or even 20 years. After you reach the cap, you hold that maximum discount for as long as you stay claim-free.

• Most UK insurers cap your no-claims bonus at 9 years.
• Some insurers cap lower (around 5 years), others allow up to 15 or 20 years.
• Once capped, staying claim-free keeps your discount at its top level indefinitely.
• Building years beyond the cap still helps if you have no-claims bonus protection.

Where insurers set the limit

The majority of UK insurers set the maximum no-claims bonus at 9 years. Some cap it lower, at around 5 years, and a minority allow you to build up to 15 or 20 years before the discount stops growing. There is no single industry-wide rule, so the exact ceiling varies from one provider to the next.

The reason for a cap is straightforward. If a discount were added to your premium every year without limit, the cost of cover would eventually fall to a level the insurer could not sustain. Capping the bonus keeps premiums commercially viable while still rewarding long-standing claim-free drivers.

Because the limit differs between providers, it pays to compare. If you already hold a long claim-free record, an insurer that recognises more years can offer a larger discount on the same risk. You can read more on how a no-claims bonus works to understand the mechanics before you shop around.

What the discount is worth at each stage

A no-claims bonus typically starts at around 30% after one claim-free year and rises with each year you avoid a claim. A common progression is roughly 40% after two years, 50% after three, and 60% to 75% once you reach five or more years. The exact percentages are set by each insurer and most do not publish their full tables.

Figures are indicative and may change between insurers.

These percentages apply to the base premium before the discount, not to a fixed amount. As average premiums shift, the cash value of any given percentage moves with them. The ABI reported an average motor premium of £560 in Q1 2026, broadly stable on the previous quarter and £20 lower than Q1 2025. A larger discount remains useful, but a 60% bonus is worth less in pounds when the underlying premium falls.

What happens once you pass the cap

Once you pass your insurer’s cap, your discount stays at its maximum level for as long as you remain claim-free. Reaching 12 or 15 claim-free years with an insurer that caps at 9 will not earn you a bigger percentage. You hold the top discount and keep it by continuing to avoid claims.

Building a record beyond the cap is not wasted, though. A longer claim-free history can support your case as a low-risk driver and matters most if you hold no-claims bonus protection. If a single claim costs you a few years of bonus, having extra years banked means you are more likely to stay at or near the maximum tier afterwards.

It helps to keep your own proof of your claim-free years. Some renewal letters now state only a truncated figure, such as “9 or more” years, rather than your full record. Insurers can also verify your history through the Motor Insurers’ Bureau No Claims Discount Database, though not every insurer submits to it, so keeping documentation is sensible.

How you earn each year of bonus

You earn one year of no-claims bonus for every full 12-month policy you complete without making a claim. You must be the main policyholder to build it. Named drivers do not usually accrue a bonus of their own, although a small number of insurers now offer a named-driver no-claims scheme that records proof of claim-free driving.

A no-claims bonus only applies to one car at a time. If you take out a second policy, you cannot use the same bonus on both vehicles. Each policy builds its own record, so running two cars means two separate histories.

If you also drive a van, the rules work in a similar way but bonuses are not always transferable between car and van cover. Our guide on no-claims bonus on van insurance sets out how that works.

How long your bonus lasts if you stop driving

Most UK insurers will accept a no-claims bonus that is up to two years old. A minority stretch this to three years, but that is less common. If you go more than two years without a car insurance policy, you will usually have to start building your bonus again from scratch.

This matters if you sell a car, drive abroad for a while, or take a break from owning a vehicle. Keeping the gap under two years protects the years you have already earned. If you know a longer break is coming, it is worth checking each insurer’s specific rule before you let cover lapse.

When protecting your bonus makes sense

No-claims bonus protection is an optional add-on that lets you make a limited number of claims, usually one or two within a three to five year period, without losing your discount. Most insurers only offer it once you have at least four years of bonus built up. It preserves your discount percentage, not your overall premium.

That distinction matters. Even with protection, your insurer can still raise your base premium after a claim because your risk profile has changed. The protection keeps the discount intact, but the figure it applies to can rise. For drivers with several years banked, it can still soften the effect of an unavoidable claim.

Whether it is worth paying for depends on the cost of the add-on against the value of the bonus you are protecting. Our guide on no-claims discount protection walks through the trade-off in more detail.

Does building more years still pay off?

Building more claim-free years still pays off even once you hit the cap, because the value sits in your protection cushion rather than a bigger percentage. With premiums having eased over the past two years, the cash saving from a maximum bonus is smaller than it was at the December 2023 peak, but it remains a meaningful part of your price.

Younger drivers stand to gain the most from starting their record early. They typically have the fewest claim-free years and the highest premiums, so each year of bonus removes a larger share of a larger bill. Building a clean record from the first policy onwards compounds into a strong position by the time the cap is reached.
