Comprehensive car insurance combines the legal third party cover, protecting others if you cause an accident, with extensive protection for your own vehicle, regardless of who is at fault. The terms “fully comprehensive” and “comprehensive” mean the same thing.
Most comprehensive policies also include windscreen cover, personal accident benefits, medical expenses, limited cover for personal belongings stolen from your car (typically £100 to £500), EU driving cover, and audio equipment protection.
There are three levels of car insurance in the UK. Fully comprehensive offers the widest protection, covering damage to your own car as well as third party liability. Here is exactly what each level includes.

| Accidental damage to your car | |||

It sounds counter-intuitive, but fully comprehensive car insurance is often cheaper than third party only. Here is why.
The reason is straightforward: lower-risk drivers tend to choose comprehensive cover, which brings the average premium down. Higher-risk drivers, particularly younger and less experienced drivers, are more likely to take out third party only to save money, which pushes the average cost of third party policies up. The result is that for many drivers, especially those over 25 with a few years of no claims discount, fully comprehensive is the same price or less than third party.
Note: This does not mean third party is always more expensive. For very young drivers or those with a poor claims history, third party may still be cheaper. The only way to know for certain is to compare quotes for all three levels via Brumble.

One of the most common misconceptions about fully comprehensive insurance is that it automatically covers you to drive other cars. This is not true for most policies. Some comprehensive policies include a "driving other cars" (DOC) extension, but many insurers have removed it in recent years. Even where DOC is included, it typically only provides third party cover on the other vehicle, not comprehensive protection.
Look at your certificate of motor insurance, not just the policy document. If DOC is included, it will be listed as an extension on your certificate. If it is not listed, you are not covered to drive other cars.
Even with DOC, you are only covered at third party level on the other vehicle. This means damage to the other car is not covered. Only damage you cause to other people or their property is insured.
DOC extensions usually only apply to the policyholder (not named drivers), only cover cars that are already insured by someone else, and often exclude drivers under 25. Business use is also typically excluded.
If you regularly need to drive a car that is not your own, consider a separate short-term policy. See our temporary car insurance page for options.
With comprehensive insurance, you pay an excess towards any claim. This has two parts: a compulsory excess set by your insurer (typically £100 to £350), and a voluntary excess you choose on top of that.
Scenario: Your car is damaged in an accident. The repair costs £2,500.
£0 voluntary excess
(£350 compulsory)
£250 voluntary excess
(£350 compulsory)
£500 voluntary excess
(£350 compulsory)
Worked example for illustration only. Compulsory excess of £350 used as an example. Actual compulsory excess varies by insurer and policy. Voluntary excess is chosen by you when setting up the policy.
A higher voluntary excess typically reduces your premium but increases what you pay out of pocket if you claim. Choose an amount you could comfortably afford. There is no point setting £500 voluntary excess if an unexpected claim would cause financial difficulty.
Understanding what happens when you need to claim helps you make informed decisions about your cover. Here are four common scenarios and how comprehensive insurance responds.
Comprehensive insurance covers theft. Report the theft to the police and get a crime reference number, then contact your insurer. If the car is not recovered, the insurer will pay out the market value of the car minus your excess.
Most comprehensive policies include windscreen cover as standard, often with a lower excess (typically £75 for repair, £150 for replacement). You can usually arrange the repair directly via your insurer approved provider without it affecting your no claims discount.
If another driver is at fault, your insurer will handle the claim and recover costs from the other driver insurer. Your no claims discount should not be affected once the claim is settled as non-fault, though this can take time.
This is an at-fault claim. Comprehensive cover will pay for the damage to both cars, but you will need to pay your excess and it will affect your no claims discount. Always leave your details or report it to the police within 24 hours, as failing to do so is a criminal offence.
Even with comprehensive cover, there are important exclusions to be aware of. Always read the policy documents before you buy.
| Not Covered | Why |
|---|---|
| Driving under the influence | Drink or drug driving invalidates all cover |
| Uninsured drivers using your car | Only named or permitted drivers are covered |
| Deliberate damage | Intentional damage to your own vehicle is excluded |
| Wear and tear or mechanical breakdown | Normal deterioration and breakdowns are not insurance matters |
| Business use (unless declared) | Standard policies cover social, domestic and pleasure only |
| Driving other cars | Check your certificate, as this is not automatic on all policies |
Comprehensive cover bundles several features as standard but treats others as optional extras. Here is how it typically breaks down.
Standard and optional features vary by insurer and policy. Always check your policy schedule to confirm exactly what is included in your cover.
Comparing quotes is the single most effective step, but there are several other ways to reduce your comprehensive car insurance premium.
Compare multiple quotes. Prices vary by hundreds of pounds between insurers for identical cover. Never accept a renewal without comparing via Brumble first.
Build your no claims bonus. Each claim-free year reduces your premium. Insurers typically offer significant discounts for long claim-free records. Read more in our no claims bonus protection guide.
Choose a lower insurance group car. Small, reliable cars in groups 1 to 10 are significantly cheaper to insure than performance models.
Increase security. Thatcham-approved alarms, immobilisers, and trackers can reduce premiums. A dash cam also provides evidence in disputed claims.
Park in a garage or driveway. Secure overnight parking reduces both theft risk and your premium.
Limit your annual mileage. Lower mileage means lower risk. Accurately estimating your annual mileage can reduce your quote.
Pay annually. Monthly payments add interest, typically at 15 to 20 per cent of the total premium. Paying in full saves a significant amount over the year.
Consider telematics. Safe drivers could see significant savings with a black box policy, especially if you are under 25.
