What is comprehensive car insurance?

Comprehensive car insurance offers the highest level of cover for you and your car. Unlike other policies, comprehensive cover can pay out if you damage or write off your car, even if you're at fault.

It's sometimes known as ‘fully comprehensive’ or ‘fully comp’ insurance, but these terms can be misleading as no insurance policy covers all eventualities.

Car insurance policies will vary depending on the provider you choose, so always check the terms and conditions to see what is and isn’t covered.

What’s the difference between comprehensive and other types of car cover?

Comprehensive isn’t the only kind of car insurance you can get. Here's how it compares to the two other options – third party only and third party, fire and theft:

Comprehensive

  • tick

    The highest level of cover you can get

  • tick

    Covers damage and injuries to others and their property

  • tick

    Usually covers you for theft and fire damage

  • tick

    Covers repairs to your car after an accident, even if you’re at fault

  • tick

    Can pay out if your car is written off

  • cross

    Doesn’t automatically let you drive other cars

  • cross

    Won’t always cover theft – for example, if you leave your car unlocked

Third-party only

  • tick

    Third-party car insurance is the minimum level of cover required by law

  • tick

    Covers you for damage to another vehicle or person in an accident

  • cross

    Won’t cover any damage to you or your car

Third-party, fire and theft

  • tick

    Third-party, fire and theft insurance offers the same cover as third-party, plus protection if your car is stolen or fire damaged

  • tick

    Could be useful if you don't drive often or your car isn't worth much

  • cross

    Won’t cover the costs of repairing or replacing your car if it’s damaged or written off in an accident that you caused

What affects the price of comprehensive car insurance?

The cost of your premium depends on a range of factors, including your age, driving history, address and where you keep your car at night.

Insurance providers will consider all the above to determine how likely you are to make a claim. The level of risk will be reflected in the price of your policy.

Why is comprehensive car insurance cheaper than third-party?

Comprehensive car insurance is often cheaper because drivers who opt for full cover may be considered lower risk by insurance providers.

It shows that you’re careful, responsible and likely an experienced driver, as young and new drivers tend to choose third-party policies. Less experienced drivers are seen as riskier to insure, meaning higher premiums.

What does comprehensive car insurance cover?

Compensation costs if someone claims against you for an injury you’ve caused

Personal injuries that you sustain following an accident

Some cover for personal belongings that are damaged or stolen while in your car

The full cost of repairing your car after an accident

What add-ons can I get with comprehensive car insurance?

You can tailor a comprehensive policy to you. Some policies include extra features as standard, while others offer them as optional add-ons for an additional cost..
Car icon

Courtesy car cover

This provides you with a courtesy car while yours is being repaired after an accident. This may come in handy if you need your car to get to work or take the kids to school, for example.

Breakdown icon

Breakdown cover

Breakdown cover offers roadside assistance if your car breaks down. It can also include recovery to a garage for repairs if the problem can’t be fixed there and then.

Windscreen

Windscreen cover

Windscreen insurance could cover the cost of repairing or replacing a broken windscreen, as well as side and rear windows.

Gavel icon

Motor legal expenses

Motor legal protection could cover expensive legal fees if an accident you’re involved in ends up in court. It could also help recoup losses, such as lost earnings or medical costs.

Work bag icon

Personal belongings cover

Most comprehensive policies offer some standard cover for the things you take in your car. You may be able to up your cover limits by paying a little extra.

Percentage in circle icon

No claims bonus protection

Building up your no claims discount (NCD) could get you a cheaper quote on your car insurance. NCD protection can help you keep your NCD if you make a claim.

Location pin icon

Driving in Europe

All car insurance policies in the UK must include at least the minimum TPO cover needed to drive in Europe. But this cover is usually only provided for a limited period.

Hospital icon

Personal accident cover

Personal accident insurance could provide compensation if you or your passengers suffer a life-altering injury or are killed in a car accident.

Car keys

Key cover

If you lose your car keys or they’re stolen, key cover could help replace them and reprogramme your alarm and immobiliser.

Fuel pump

How can I get cheap comprehensive car insurance?

Though some factors may be out of your control, there are a range of things that could help you reduce the price of your cover.

Broadband speed icon

Reduce your mileage

Driving less could make you seem lower risk to insurance providers. Therefore, fewer miles could lead to a cheaper quote.

People icon

Add a responsible driver to your policy

People typically save £158 on their annual car insurance by adding a named driver to the policy3.

However, don’t be tempted to say that someone is the main driver if they’re not. This is called fronting, and it's a type of insurance fraud.

Hand with coins icon

Pay upfront

Insurance providers usually charge interest on monthly instalments, so paying for the whole year upfront could work out cheaper.

In fact, we've seen that people typically pay £500 for annual comprehensive cover, compared with £714 when they pay monthly3.

Hand with coins icon

Increase your voluntary excess

This is the amount you’ll agree to pay towards a claim. Choosing a higher voluntary excess can bring your premium down.

But you may have compulsory excess as well – not all policies have this, but most do. That’s the amount you have to pay towards a claim, which is set by the provider.

Just be sure you can afford to pay both, should you need to claim.

Car with shield

Choose a car in a lower insurance group

Cars with smaller, less powerful engines tend to sit in lower insurance groups and are typically cheaper to insure. For example, small cars with a less than 1.0-litre engine cost £532 to insure, while 2.0-2.4 engines cost £6803.

Unsure which group your car is in? Use our quick insurance group checker to find out.

Padlock icon

Boost your car's security

Adding extra security features, such as an immobiliser or steering lock, can lower your risk of theft and potentially bring your premiums down.

Car and repair garage

Park your car safely overnight

Parking on a driveway overnight rather than the street typically saves drivers £247 a year on car insurance4.

If you don’t have a driveway, try to park as close to your home as possible, ideally on a well-lit residential road. But if that’s not possible, other safe options could include:

  • A private car park if you live in a block of flats and have access to resident parking

  • Secure public car parks

  • A locked compound.

Choose a telematics policy

You can get comprehensive cover with telematics – also known as a black box. It’s a small device or app that tracks your driving style and shares that information with your insurer.

Proving you’re a safe driver could reward you with cheaper insurance when it’s time to renew.

Build up your no-claims discount

The longer you stay claim-free, the higher your no-claims discount (NCD) will normally get. Providers tend to reward drivers with a big NCD with a lower premium.

According to our data, drivers with six years' NCD typically pay up to £476 less than drivers with just one year4.

FAQs

If I have comprehensive car insurance, can I drive any car?

No, you can’t just drive any car with comprehensive cover. Typically, comprehensive cover only allows you to drive someone else’s car in emergency situations. Also, it will likely only cover third-party damage.

Check your policy wording so you know what cover you have. And if you’re unsure, speak to your insurance provider.

If you want to drive someone else’s car, ask whether you can be added as a named driver to their car insurance policy. Or, if you only need to drive someone else’s car for a short time, consider temporary car insurance.

Does comprehensive insurance cover other people to drive my car?

No, comprehensive car insurance does not insure other people to drive your car. You’ll need to add them as a named driver to your car insurance.

Is it worth getting comprehensive car insurance?

It could be worth getting comprehensive car insurance. It offers the most extensive cover and is often cheaper than other policy types.

When you use Compare the Market, you can compare different cover levels from a range of providers. So you can easily see the different options for your needs, situation and budget.

What does fully comp mean?

Fully comp is just another name for comprehensive car insurance. It’s short for fully comprehensive, but we don’t use that term because it could be misleading.

Comprehensive car insurance offers the most extensive level of protection you can get. But it doesn’t cover absolutely everything. Policies vary depending on which insurance provider you choose.

That’s why we advise reading the terms and conditions of any policy carefully before you buy, so you can understand exactly what’s included and what’s not.

Does comprehensive car insurance cover engine failure?

Yes, comprehensive car insurance typically covers engine failure if it's caused by an accident, vandalism or natural disaster.

You won't usually be covered for engine failure caused by wear and tear.
