## Quick answer

UK law requires at least third-party motor insurance. Comprehensive cover adds fire, theft and damage to your own car. Price depends on your risk profile — age, postcode, car group, mileage and claims history — not just the cover level you choose.

Car insurance is mandatory but widely overpaid at renewal. Understanding cover types, excesses and optional add-ons stops you buying the wrong policy — or duplicating cover you already have on a packaged bank account.

## Key facts

- Minimum legal cover: third-party liability for injury and property damage to others
- Comprehensive covers your vehicle for damage, fire and theft as well as third-party claims
- FCA rules since 2022 ban 'price walking' — renewal quotes cannot exceed equivalent new-customer prices
- Car insurance groups (1–50) influence premiums — lower groups are cheaper to insure

## Types of cover

Third-party only is the legal minimum. Third-party fire and theft adds protection for your car against fire and theft. Comprehensive adds accidental damage to your vehicle and usually includes windscreen and legal cover — yet can still be cheaper than lower tiers for some drivers because of how risk pools work.

## What affects your premium

Insurers price on age, driving history, postcode crime and accident rates, annual mileage, occupation, where the car is kept overnight, and the vehicle's insurance group and repair costs.

## Frequently asked questions

### Is comprehensive always more expensive?

No — comprehensive is sometimes cheaper than third-party because higher-risk drivers historically chose lower cover levels, skewing the risk pool.

### Can I drive someone else's car on my policy?

Only if your policy explicitly includes 'driving other cars' — often third-party only and restricted to emergencies. Do not assume you are covered.
