Why has my car insurance gone up in 2026?

Two separate things are pushing your renewal up

The market-wide answer is claims inflation. Insurers do not price on what cars cost to buy; they price on what cars cost to fix. The average accidental damage claim reached £3,699 in Q1 2026, an 8% rise in three months, and total vehicle repair claims hit £1.9bn, up 3% on the previous quarter. Repair materials such as paint are up around 16% in a year, repair-trade wage inflation is running near 4.2%, and modern cars carry sensors, cameras and driver-assistance systems that turn what used to be a cheap job into an expensive one — a windscreen replacement on a camera-equipped car can cost roughly three times more than on a basic model because the system needs recalibrating afterwards. Forecasters expect overall claims inflation of 8–10% across 2026.

The individual answer is usually something else entirely. The FCA’s price-walking ban has applied since January 2022, so your insurer is not allowed to raise your renewal above the equivalent new-business price simply because you are loyal. That means if your price jumped sharply while the market moved only a few pounds, the cause is almost always a change on your own record: a claim (even a non-fault one), a new endorsement, a house move, a change of car, a lapsed no-claims year, an added driver, or switching from annual to monthly payment. Work through the checklist below before assuming you have been treated unfairly.

Nine reasons your own price jumped

If your renewal rose by far more than the few pounds the market moved, work down this list. In our experience one of these explains almost every large individual increase:

1. You made a claim — including a non-fault one. Non-fault claims still raise premiums, because statistically drivers who have been hit are more likely to be involved again. An at-fault claim typically adds 20–50% for three to five years.
2. You lost or paused a no-claims year. NCD is the biggest discount most drivers hold. Breaking the run — through a claim, or by not being insured for a period — removes a large percentage discount all at once.
3. A conviction landed. DVLA endorsements must be declared for five years, or eleven for drink-driving codes such as DR10. Even a single SP30 typically adds around 5%.
4. You moved house. Postcode is priced at full postcode level, so a move of a few streets can cross into a higher-rated sector. London averages £833 against £480 in South West England.
5. You changed car. A higher insurance group, a costlier parts supply chain or a model with a poor theft record all move the price. Newer models are also rated under Thatcham’s Vehicle Risk Rating, which scores repairability and security explicitly.
6. You added or removed a driver. Removing an older experienced driver can raise a premium as much as adding a young one.
7. You switched to paying monthly. This is credit at typically 20–30% APR — roughly £138 a year on a £600 policy. The insurance did not get more expensive; you borrowed the premium.
8. You let it auto-renew. The price-walking ban means your insurer cannot penalise loyalty specifically, but it does not oblige them to match the cheapest price in the whole market.
9. You aged into or out of a band. Prices fall steeply to about 21 and flatten through middle age — but they begin rising again past 75.

What to do about it, in order of return: shop the whole market 21–26 days before renewal (buying that far ahead is commonly worth 20–30% versus buying on the day); pay annually if you can; check your mileage and job description are accurate rather than pessimistic; consider a higher voluntary excess you could genuinely afford; and run comprehensive alongside third-party cover, because comprehensive frequently quotes lower.
