What is third-party car insurance?

Third-party insurance is the most basic level of car insurance you can get – and the legal minimum you need to drive on UK roads.

It offers cover if you damage another person’s car or injure someone while you’re driving.

But you won’t be covered for your own injuries or any damage to your car if an accident is your fault. You’ll need to foot the bill for this yourself.

What does third-party insurance cover?

Typically covered

  • Damage to someone else’s car in a road accident

  • Damage to another person’s property – for example, if you crash your car into a neighbour’s wall

  • Injury to a passenger or driver of another car

  • Injury to a passenger in your car

Not typically covered

  • Damage to your own vehicle (if the accident was your fault)

  • Repair or replacement costs if your car is stolen, broken into or damaged by fire

  • Medical costs if you’re injured, such as physiotherapy

How much does third-party insurance cost?

According to our data, third-party car insurance typically costs2:

£1,302
a year

Keep in mind that the cost of your premium will depend on your personal circumstances, including:

  • How old you are

  • Where you live

  • The make and model of your car

  • What insurance group it’s in

  • How much the car's worth

  • How many miles a year you drive.

Is third-party car insurance cheaper than comprehensive?

People often assume third-party insurance will be the cheapest as it offers the least cover, but that often isn't the case.

As shown above, third-party cover can be expensive. By comparison, third-party, fire and theft typically costs £962, while comprehensive cover costs £593 per year2.

Third-party cover might be more expensive because:

  • Higher-risk drivers choose third-party cover to try and save money, but those drivers are then priced more expensively by providers, or

  • With fewer third-party policies sold nowadays, the market is less competitive and therefore more expensive.

Some people just automatically assume third party cover is cheaper than comprehensive, because it's not as comprehensive as comprehensive cover. But that's not always the case.

So it's just worth trial and error checking just to see what's cheapest for you. Adding safety features or security features, maybe a dashcam for example, that could sometimes bring the price down, as well as obviously adding to the security and safety of your motor. So that's worth checking.

What happens if I’m involved in an accident with third-party cover?

If the accident is your fault

You’ll need to claim on your insurance policy so your provider can settle a pay-out with the other person’s insurance provider.

This could include the cost of fixing damage to the other person’s car or personal injury claims. You could also lose your no-claims discount unless it’s protected under your policy.

If the accident isn’t your fault

You should be able to claim money back from the other driver’s car insurance policy or get it to repair your motor.

Your no-claims bonus shouldn’t be affected because you’re not claiming on your own insurance policy.

What’s the difference between third-party and comprehensive insurance?

Comprehensive insurance

  • tick

    Comprehensive insurance is the highest level of cover available

  • tick

    It covers damage to your own vehicle, as well as damage to someone else’s car

  • tick

    It can also cover damage to the personal belongings in your car, and injury to you and other people

  • tick

    Comprehensive insurance gives you more cover than you legally need

Third-party insurance

  • tick

    Third-party insurance gives you the minimum level of cover

  • tick

    You must have at least third-party car insurance by law, whereas comprehensive cover is optional

  • cross

    You won’t get any payout if your car is damaged or you’re injured

When is third-party insurance a good option?

If your car isn’t worth very much, you might want the most basic insurance cover possible.

This is because the cost of fixing your car might be more than it’s worth, making the repairs not worth bothering with. Alternatively, the cost of repairs may be so low that you’re able to cover the expense yourself.

Another instance when third-party insurance might make more sense is for drivers who don’t drive their car very often.

Is third-party cover right for me?

It’s important to weigh up the pros and cons before deciding if third-party insurance is right for you.

Potential benefits

Third-party insurance may be right for you if:

Your car is older and isn’t worth very much

If the cost of fixing your car is more than it’s worth, it might make sense to find a cheap third-party car insurance policy.

You don’t drive your car very often

Having the most basic level of cover to legally drive in the UK might be perfectly fine for your needs.

Potential disadvantages

Potentially, there are financial risks if you only have third-party cover:

It won’t cover damage to your car

If you cause an accident, you’ll have to pay for repairs yourself.

You won’t be covered for injuries

If the accident is your fault, third-party car insurance won’t cover any medical bills.

It can be more expensive

Drivers with third-party only cover are often considered higher risk. You may find that you’ll pay more for third party insurance than for a comprehensive policy.

Check the cost of third-party insurance against comprehensive cover and third-party, fire and theft insurance. Although third party is the most basic type of policy, it’s often not the cheapest.

What our expert says...

“Third-party cover is the minimum level of car insurance that drivers legally need. It typically covers the cost of damage to another person’s vehicle, as well as any compensation costs for injuries caused to other people. Drivers with third-party cover tend to pay more as they’re likely to be younger, high-risk drivers.

"When you come to renew your car insurance, it’s always worth shopping around and comparing different types of policy. This will help you get a great deal with the right amount of protection.”

What added extras can you get with third-party cover?

Courtesy car cover

No-claims discount protection

If you’ve built up a decent no-claims discount, you can protect it by adding this cover.

Just remember that add-ons can bump up the price of your premium, so only buy an extra cover if you really need it.

Some comprehensive policies may include additional cover as standard. Comprehensive insurance could work out cheaper than a third-party policy with a range of extras added on.

FAQs

Does third-party only insurance cover you for theft?

No, third-party insurance doesn’t cover theft. But you could be covered if you choose third-party, fire and theft, or comprehensive car insurance.

Is it legal to drive with third-party insurance?

Yes, third-party insurance is the legal minimum you need to drive in the UK. It will also cover you to drive your car in most European countries.

However, you usually won’t be insured to drive other cars. Before driving someone else’s car, it’s best to be added to their insurance as a named driver.

What is third-party, fire and theft cover?

Third-party, fire and theft insurance offers the same cover as third-party insurance, but also covers you if your car is stolen or damaged by fire.

Third-party, fire and theft could be an option if your car is relatively cheap and straightforward to repair.

It’s a good idea to compare the cost of third-party, fire and theft cover with comprehensive insurance, because basic policies aren’t necessarily the cheapest.

Is it cheaper to pay for third-party cover monthly or annually?

It’s usually cheaper to pay for your car insurance annually, in one lump sum. That’s because you’ll typically be charged interest if you pay monthly.

Drivers typically pay £509 when paying annually, compared to £734 when paying monthly3.
