Car insurance is a legal requirement in the UK that provides financial protection when you drive. In exchange for paying a premium, your insurer agrees to cover certain costs if you have an accident, your car is stolen, or you damage someone else's property. UK law requires all drivers to have at least third-party insurance.
Accidental Damage refers to any sudden and unforeseen harm to your vehicle that is not the result of wear and tear.
What your car is worth at the time of a claim, considering depreciation. If your car is written off, this is typically what your insurer will pay you.
The total amount you pay for your car insurance each year. You can usually pay monthly, but this often costs more due to interest charges.
A claim where you are considered responsible for the incident. This typically affects your no claims bonus and may increase future premiums.
Also called telematics insurance. A device fitted to your car monitors how you drive. Good driving can lead to lower premiums, making it popular with young drivers.
An optional add-on that provides roadside assistance if your car breaks down. Not included in standard car insurance policies.
An independent intermediary who arranges and sells insurance on behalf of different insurers. They can help you find the best deal across multiple providers.
A legal document proving you have valid car insurance. You must be able to produce this if asked by police.
A request to your insurer to pay for damage, injury or loss covered by your policy. Making a claim may affect your no claims bonus.

The amount you must pay towards any claim before your insurer pays the rest. Made up of compulsory excess (set by insurer) plus voluntary excess (chosen by you). Higher excess usually means lower premiums.

Any claim where your insurer cannot recover costs from another party. This affects your record even if the accident wasn't your fault.

An optional add-on that lets you make a limited number of claims without losing your bonus. However, your overall premium may still increase after a claim.
A claim where your insurer can recover all costs from the other party. This typically does not affect your no claims bonus.
