Every car used or kept on a public road in the UK must be insured, and the law has been enforced automatically since 2011: the DVLA compares its vehicle records with the Motor Insurance Database, and an uninsured car that is not declared off the road with a SORN attracts a fixed penalty without anyone ever pulling you over. That makes motor insurance the one product almost every driver buys every year, and the one most of us buy without reading. This section is here to fix that.
- Cover comes in three levels. Third party only is the legal minimum, third party fire and theft adds cover for your own car being stolen or burnt, and comprehensive adds damage to your own car from any cause, including your own fault.
- Your price is built from rating factors: your age, licence length and claims history, where the car is kept, what it is (its insurance group), how it is used and how many miles it does, plus the excess you agree to pay.
- Since January 2022 the FCA has banned the loyalty penalty: an insurer may not quote a renewing customer more than it would charge a new customer for the same policy through the same channel. Renewal quotes can still rise, but not simply because you stayed.
- Insurance Premium Tax of 12 per cent is added to every motor premium, and every policy sold at a distance carries a 14-day cooling-off period.
What the three levels actually cover
Third party only pays for injury to other people and damage to their property and vehicles. It pays nothing towards your own car. It is the legal minimum under the Road Traffic Act 1988, and it is rarely the cheapest option in practice, because insurers price it for the drivers who choose it. Third party, fire and theft adds cover if your own car is stolen, damaged in an attempted theft or damaged by fire. Comprehensive adds accidental damage to your own car regardless of fault, and usually a bundle of extras such as windscreen cover, personal accident cover and driving other cars with third-party cover only, which is the extension most people misunderstand. The complete guide walks through each level and the small print that comes with it.
What decides the price
Insurers do not price the car; they price the risk of you, in that car, on that road, for a year. The factors that matter most are the ones that predict a claim: your age and years of licence, any convictions or points, your claims and no-claims history, the postcode where the car sleeps, the car's insurance group from 1 to 50, the annual mileage you declare, whether the car is used for commuting or business, who else drives it, and the voluntary excess you choose on top of the compulsory one. Two policies with identical cover can differ by hundreds of pounds because one driver declared the details accurately and one guessed. How excesses work and how the no-claims discount is earned, protected and lost are the two levers you control directly.
Reading a policy before you need it
You will receive four documents, and only one of them is proof of insurance. The certificate is the legal document that shows who is covered to drive what. The schedule lists your personal details, the excesses and any endorsements. The policy wording is the contract, with the exclusions. The Insurance Product Information Document is the standardised one-page summary the FCA requires. When a claim goes wrong, it is almost always because of something in the wording or the schedule that was never read: an undeclared modification, a mileage limit, a named-driver condition or a security requirement. Our guides on modifications you must declare and fronting cover the two disclosure failures that most often void a policy.
When something goes wrong
A claim is a negotiation you can prepare for. Know your excess before you ring, understand that a total loss is settled at market value rather than what you paid, and check whether your car sits in a write-off category that lets you buy it back. If you bought the car on finance or brand new, the gap between the payout and what you owe is exactly what GAP insurance exists for, and the FCA's 2024 intervention changed how it can be sold. If your circumstances change mid-term, temporary cover exists for the awkward gaps: short-term policies are priced by the hour and the day.
The special cases
Some situations have their own rules. Young and new drivers are usually offered telematics policies, which trade privacy for price. Anyone with penalty points on their licence needs to know exactly what to declare and for how long, because the rules for insurers are not the rules for the DVLA. And electric cars are priced differently again, because their repair costs and battery values behave differently from petrol and diesel cars.
