Comprehensive vs third party insurance: what is the difference?

Updated June 2026 7 min read

Quick verdict

Comprehensive insurance covers damage to other people plus your own car, while third party only covers damage or injury you cause to others. For most drivers, comprehensive is the better place to start because it covers far more and is often the same price or cheaper than third party.

Option A

Comprehensive

Comprehensive car insurance is the highest standard level of cover. It usually includes third party liability, fire and theft, and damage to your own car.

Option B

Third party

Third Party Only insurance is the legal minimum in the UK. It covers other people and their property, but not repairs to your own car.

Side-by-side comparison

Third party insurance is the legal minimum and covers damage or injury you cause to other people and their property. Comprehensive includes that cover and usually protects your own car too, even if an accident is your fault.

Cost examples

Newer family car

Comprehensive usually makes sense because damage to your own car could be expensive, and fire or theft cover matters.

Likely fit: Comprehensive

Low-value runaround

Third party may be worth checking if you would not repair the car after a fault accident, but compare comprehensive quotes too.

Key check: Compare both

Trying to cut premiums

Do not assume third party is cheaper. Insurers often price it higher because riskier drivers tend to choose basic cover.

Common surprise: Comprehensive can be cheaper

FAQs

What is the difference between comprehensive and third party insurance?

Third party insurance covers the damage and injury you cause to other people and their property, but not your own car. Comprehensive covers all of that plus damage to your own car, fire and theft, and usually extras such as windscreen cover.

Is comprehensive better than third party insurance?

For most drivers, yes. Comprehensive covers far more, and it is often the same price or even cheaper than third party. It is worth comparing quotes for both before deciding.

Why is comprehensive insurance sometimes cheaper than third party?

Higher-risk drivers are more likely to choose third party cover, so insurers often price the basic level higher to reflect that risk. This means the lower level of cover can end up costing more.

Does third party insurance cover my own car?

No. Third party only covers damage and injury you cause to others. If your own car is damaged in a fault or single-vehicle accident, you would have to pay for repairs yourself.

What is the difference between third party and third party fire and theft?

Third Party Only covers damage to others but nothing for your own car. Third Party, Fire and Theft adds cover if your own car is stolen or damaged by fire, sitting between basic third party and comprehensive cover.
