Claims inflation is the rate at which the cost of settling claims rises, above the general cost of living. It is the main reason premiums climb even when the number of claims stays flat. Insurers pay more for parts, labour, and care, and those rises pass through to the price you pay at renewal. Understanding the drivers explains why your premium moves and why some years jump more than others.
What claims inflation is not
Do not confuse it with the number of claims. A quiet year for accidents can still see costs rise if each claim costs more to fix. Claims inflation measures the average cost per claim, not the count. Our guide to how insurance settlements and payouts work explains what makes up that cost.
The main cost drivers
Several forces push the average claim cost up at once.
- Vehicle repair: modern cars carry sensors and complex panels, so a minor bump costs more to put right.
- Parts and labour: shortages and wage pressure raise the bill for both.
- Medical and care costs: injury and liability claims rise with the price of treatment.
- Supply chains: global delays stretch the time a claim stays open and the cost of替代 parts.
- Reinsurance: when global catastrophe losses rise, the cost of backing UK claims follows.
For households, weather is the wildcard. A wet year of escape-of-water and storm claims lifts the average home claim, as our analysis of home insurance claims data shows.
How it shows up in the market
The effect is visible in the published figures. ABI data for early 2026 showed motor repair payouts near record levels and a combined ratio above 100%, meaning insurers paid out more than they took in. Our briefing on motor claims costs and the combined ratio covers that quarter, and our analysis of UK motor premium trends tracks how the rise reached the price.
When claims inflation runs ahead of premium income, insurers raise prices or tighten terms to restore balance. That is the mechanism that turns a cost rise in the body shop into a rise on your renewal.
Why it matters to you
Claims inflation is the part of your premium you least control. You can shop around and cut your own risk, but the average cost of a claim is set by the wider market. The Financial Conduct Authority watches that pass-through to make sure it is fair, and the Consumer Duty expects firms to show the value behind the price.
The pattern also varies by product. Motor and home feel it most, because both depend on physical repair and supply chains. Our guide to why home insurance premiums are moving and our motor premium trends analysis break down each line.
