Comprehensive vs third party car insurance explained
The three tiers of car insurance cover
UK car insurance is offered at three main levels: third party only (TPO), third party fire and theft (TPFT), and comprehensive. Each tier covers more than the last.
Third party only
Covers damage you cause to others — their vehicles, property, and personal injury claims against you. It does not cover damage to your own vehicle, theft, or fire damage to your own car.
Third party, fire and theft (TPFT)
All of the above, plus cover if your own vehicle is stolen or damaged by fire. Does not cover other damage to your own vehicle.
Comprehensive
All of the above, plus cover for damage to your own vehicle — whether from an accident, weather, vandalism, or other covered events. Usually includes windscreen cover, personal accident cover, and other additional benefits.
When might TPFT be appropriate?
TPFT may be worth considering if: your car is older and its market value is modest; you could replace it from savings without financial hardship; and the premium saving over comprehensive is meaningful. Use our comprehensive vs TPFT calculator to compare the numbers over your ownership period.
When comprehensive may be worth considering
Comprehensive cover may be worth considering if: your vehicle has significant market value; you could not easily replace it from savings; you park in areas with a higher risk of vandalism or accidental damage; or the premium difference is small. It is also worth noting that comprehensive premiums are not always significantly more expensive than TPFT — sometimes the gap is small.
Factors affecting the comparison
Depreciation matters. A car losing value over time means the potential comprehensive payout also falls each year. Factor in how quickly your vehicle is likely to depreciate when comparing the options over a multi-year period.
Frequently asked questions
TPFT is typically cheaper, but not always. For older, lower-value cars the price difference can be small. For newer or higher-value vehicles, comprehensive is usually significantly more expensive but covers your own vehicle damage.
The minimum legal requirement in the UK is third party only (TPO) — which covers damage you cause to other people, their vehicles, and their property. TPFT adds fire and theft cover for your own vehicle. Comprehensive adds own-damage cover.
It depends. If the market value of your car is low, the potential payout from a comprehensive policy for damage to your own vehicle is also low. Whether comprehensive is worth the extra cost depends on the premium difference and whether you could replace the car from savings.
