Third-party car insurance covers damage or injury you cause to other people and their property. It does not pay anything towards your own vehicle or your own injuries. By law, it is the minimum level of insurance you must hold to drive on UK roads, under the Road Traffic Act 1988.
Short Summary
Third-party insurance pays out for damage you cause to other people's vehicles, property, and any injury claims made against you. It does not cover repairs to your own car or any losses you suffer personally.
There are three levels of car insurance available in the UK: third party only, third party fire and theft, and fully comprehensive. Third party only is the lowest level permitted by law.
Contrary to what many drivers assume, third-party-only insurance is not always the cheapest option. Insurers sometimes charge more for it because drivers who choose minimum cover are statistically more likely to make claims.
If you are involved in an accident that is not your fault, the other driver's insurance covers your costs regardless of what level of cover you hold.
What the three levels of car insurance cover
| Cover | Third party only | Third party, fire and theft | Fully comprehensive |
|---|---|---|---|
| Damage to other vehicles | Yes | Yes | Yes |
| Injury to others | Yes | Yes | Yes |
| Your vehicle stolen | No | Yes | Yes |
| Your vehicle catches fire | No | Yes | Yes |
| Damage to your own vehicle | No | No | Yes |
| Your own injuries | No | No | Often yes (varies) |
| Windscreen repair | No | No | Often yes |
What does third-party insurance pay for?
If you cause an accident, your insurer pays the other party's vehicle repair or replacement costs, any medical or compensation claims arising from injuries you cause, and any damage to third-party property such as garden walls, fences, or street furniture.
There is no limit on injury payouts under third-party liability. If you seriously injure another driver and they claim compensation, your insurer meets that cost in full. This is one of the most valuable protections the policy provides, even in its most basic form.
What does third-party insurance not cover?
Third-party insurance will not pay for any of the following:
- Repairs to your own vehicle after an at-fault accident
- Replacement of your vehicle if it is stolen or written off
- Your own medical costs after an accident
- Fire damage to your vehicle
- Vandalism or malicious damage to your vehicle
If your car is damaged in an at-fault accident, you pay for repairs out of your own pocket. If your car is older and low in value, this may be an acceptable trade-off in exchange for a lower premium. If your car is worth a meaningful amount of money, comprehensive cover is likely to be better value.
Is third-party insurance actually cheaper?
Not always. This surprises many drivers. Insurers use statistical data from the Association of British Insurers (ABI) to price policies, and drivers who choose third-party-only cover tend to be younger, less experienced, or higher-risk on average. This raises the risk profile for the insurer, which can push premiums up despite the lower level of cover.
Before assuming third-party-only insurance will save you money, always compare quotes across all three levels of cover. Many drivers find that comprehensive cover is only marginally more expensive, or occasionally cheaper, than third-party-only.
What is third party, fire and theft?
Third party, fire and theft adds two protections on top of standard third-party cover: your vehicle is covered if it is stolen, and if it catches fire. This is a popular middle-ground option. It is worth considering if your car has moderate value and you want some protection for your own asset without paying for full comprehensive cover.
What if the accident was not my fault?
If another driver causes an accident, their insurer pays for your vehicle repairs and any injury claim you make. This applies regardless of whether you hold third-party-only or comprehensive cover. However, claiming through the other driver's insurer can take time, particularly if liability is disputed. Comprehensive cover allows you to claim through your own insurer immediately, potentially faster, though your excess and no-claims bonus may be affected until fault is confirmed.
FAQ
Is third-party insurance the cheapest option?
Not necessarily. Comparison data consistently shows that some comprehensive policies are priced lower than third-party-only policies for the same driver. Always compare all three levels of cover before buying. Comparison sites such as Compare the Market, MoneySuperMarket, and GoCompare make this straightforward.
Does third-party insurance cover me driving other cars?
Some third-party policies include a "driving other cars" extension, which gives you third-party cover when driving a car you do not own with the owner's permission. This is not standard and varies by insurer; check your policy documents carefully before driving another vehicle.
Do I have to tell my insurer about an accident even if I do not claim?
Yes. Most UK insurance policies require you to notify your insurer of any accident, even if you do not intend to make a claim. Failing to do so can invalidate your policy. The Association of British Insurers recommends notifying your insurer promptly after any incident.
Can I drive without insurance if my car is not in use?
Only if you have made a Statutory Off Road Notification (SORN) with the DVLA and the vehicle is kept off the public road. Driving or keeping an uninsured vehicle on a public road is a criminal offence. The police use automatic number plate recognition (ANPR) cameras to detect uninsured vehicles.
What happens if an uninsured driver hits me?
You can claim compensation through the Motor Insurers' Bureau (MIB), which handles claims involving uninsured and untraced drivers. You do not need comprehensive insurance to make a claim through the MIB, though some conditions apply. Visit mib.org.uk for the full process.
