Car insurance: third party, third party fire and theft or comprehensive?

Q: Car insurance: third party, third party fire and theft or comprehensive?

Third party is the legal minimum in the UK. It pays for damage or injury you cause to other people, their vehicles and their property, but nothing towards your own car. Third party, fire and theft also covers your car if it is stolen or damaged by fire. Comprehensive also pays for damage to your own car, including when the accident is your fault, minus your excess. A higher level of cover is not always more expensive, so get prices for all three. The right choice depends mainly on what your car is worth, how much you could afford to pay yourself if something went wrong, and how you use the car.

The cheapest policy isn't always the one with the least cover. Compare before you choose.

The answer in 2 lines. Third party is the legal minimum in the UK. It pays for damage or injury you cause to other people, their vehicles and their property, but nothing towards your own car. Third party, fire and theft also covers your car if it is stolen or damaged by fire. Comprehensive also pays for damage to your own car, including when the accident is your fault, minus your excess. A higher level of cover is not always more expensive, so get prices for all three. The right choice depends mainly on what your car is worth, how much you could afford to pay yourself if something went wrong, and how you use the car.

The 4 steps

Work out roughly what your car is worth today, not what you paid for it. If it is written off or stolen, insurers normally pay its market value.
Ask yourself how much you could pay yourself if the car were destroyed or stolen tomorrow.
Get prices for all three levels of cover. Third party only can cost more than comprehensive, depending on your claims history and where you live (MoneyHelper).
Compare the policies line by line: excess, exclusions, courtesy car, windscreen cover and what happens if the car is written off.

Stop: danger

Never drive without insurance, even for a short trip. Police can give you a £300 fixed penalty and 6 penalty points. In court the fine has no upper limit, you can be banned, and the police can seize the car (GOV.UK).
Never give false details to get a lower price (who drives the car, where it is kept, modifications, convictions). Your insurer can refuse to pay a claim or cancel the policy.
A car you own and keep on the road needs insuring even if you don't drive it. You only stop needing insurance once it is declared off the road with a SORN (MoneyHelper).

What each level usually covers

Cover	Third party	Third party, fire and theft	Comprehensive
Injury to other people, and damage to their vehicles and property	Yes, the legal minimum	Yes	Yes
Your car stolen	No	Yes	Yes
Your car damaged by fire	No	Yes	Yes
Damage to your car in an accident you caused	No	No	Yes, minus your excess
Vandalism	No	Usually not	Usually yes
Windscreen, courtesy car, personal injury cover for you	Depends on the policy	Depends on the policy	Often included or available as an extra: check

The names of the levels and exactly what they include vary between insurers. Only your policy documents tell you what you are covered for.

How to choose

New, expensive or financed car: comprehensive is usually the safer choice. If the car is on finance or a lease, read the agreement, which may require it. MoneyHelper explains GAP insurance, an optional extra that can cover the gap between what the car is worth and what you still owe.
Older car worth very little: third party, fire and theft may be enough, but get a comprehensive price too. The difference is sometimes small, and sometimes comprehensive is cheaper.
Parked on the street: read the theft and vandalism terms closely, including any conditions about locks or where the car is kept overnight.
Little money put aside: ask yourself whether you could replace the car without help from an insurer.
In every case: compare excesses. A comprehensive policy with a very high excess protects you less than it seems. MoneyHelper explains how compulsory and voluntary excess work.

What not to do

Comparing prices only, without reading the excess and the exclusions.
Assuming comprehensive pays for everything: the excess and policy limits still apply, and a write-off is paid at market value.
Keeping an expensive comprehensive policy on a car that is now worth very little, without checking the alternatives at renewal.
Assuming any policy lets you drive other people's cars. Many do not, so check your documents before you borrow a car.
Leaving the policy to auto-renew without checking the new price and the cover.

Where you live in England

Your postcode is one of the things insurers use to set the price, along with the car, your driving history and how you use the car. Two policies at the same level can cost very different amounts in different parts of a city. Give the address where the car is really kept overnight. The legal rule is the same across the UK, including Wales and Scotland. In Northern Ireland the official guidance is on nidirect, but third party is the minimum there too.

If something goes wrong

Your insurer: the claims and complaints contacts are in your policy documents.
Hit by an uninsured or untraced driver: GOV.UK explains how to claim compensation. Follow the steps on that page and keep the police reference.
Disagreement with your insurer: make a formal complaint first. If you get no final response within 8 weeks, or you are unhappy with it, you can go to the Financial Ombudsman Service. The service is free, and you need to contact it within 6 months of the final response. You can complain online or call 0800 023 4567.

Good to know

If someone else causes an accident and they are identified, their insurer should pay for the damage to your car, even if you only have third party cover.
You can change your level of cover at renewal. Changing during the year may mean fees, so read your policy first.
For a first car or a young driver, see our guide to young driver car insurance.

Graham has a 14-year-old hatchback worth very little, kept on his drive in Norwich. He has had comprehensive cover since he bought it. At renewal he asks for all three prices. Comprehensive is barely more than third party, fire and theft, but its excess would cancel out most of any payout on a car worth so little. He picks the option with the excess he can afford, reads the theft terms and makes a note to check again next year.

Sources, verification, confidence

Verified on 6 November 2026, for England. Confidence: high for the legal minimum and the penalties for driving uninsured (GOV.UK); high for what each level generally covers (MoneyHelper) and the ombudsman's time limits; medium for what an individual policy includes, because this varies by insurer. This guide gives general rules. It does not replace reading your policy or getting personal advice, and Bobby does not recommend any insurer.
