Dictionary EntryCosts & ClaimsUK / Commonwealth: No Claims Discount (NCD)
No Claims Bonus (NCB / NCD)
A cumulative discount applied to your renewal premium for each consecutive year you hold a policy without filing a claim.
Actuarial & Contractual Mechanics
In the UK, Australia, EU, and commonwealth markets, the No Claims Bonus (NCB) or No Claims Discount (NCD) is one of the most powerful determinants of motor and home insurance pricing. For every 12 months you drive without submitting a claim against your comprehensive policy, insurers grant an incremental discount—often 30% after 1 year, reaching 60% to 75% after 5 or more consecutive claim-free years. Policyholders can also purchase 'NCB Protection' riders, permitting up to 2 at-fault claims in a 3-to-5 year window without stepping down their discount tier.
Real-World Dollar Scenario
In London, a driver with zero claims bonus faces an annual motor premium of £1,400. After building 5 years of verifiable No Claims Discount, their insurer applies a 65% discount, reducing their annual premium to just £490 for identical comprehensive coverage.
Wallet Risk: What Happens If You Get This Wrong?
Filing small claims (such as a £250 scratch or minor bumper ding) can erase 2 to 3 years of hard-won NCB tiers, leading to premium hikes that cost far more over subsequent years than paying for the minor repair out-of-pocket.
Quick Knowledge Check
If you have 5 years of NCB and file a minor £300 claim without NCB Protection, what is typically the financial consequence?
•Your policy is immediately cancelled and you are blacklisted from UK insurers.
Incorrect. A claim simply steps down your discount tier; it does not lead to contract cancellation.
You lose 2 years of your NCB discount tier, significantly raising your renewal premiums for several years.
Correct! Standard 'step-back' rules reduce your NCB by 2 years per claim, often wiping out hundreds of pounds in renewal savings.
•Nothing happens as long as the claim amount is under £500.
Incorrect. Any at-fault claim paid by an insurer affects your NCB unless you have paid for protected NCB cover.
•The insurer doubles your statutory compulsory excess.
Incorrect. Excess is a separate policy parameter set at inception.
