Car insurance, explained

Car insurance pays out if you injure someone or damage their property while driving and, depending on the level of cover, if your own car is damaged or stolen. In the UK it is a legal requirement: you must have at least third party cover to use a vehicle on a road or other public place.

There are three main levels of cover: third party only, third party fire and theft, and comprehensive. The price depends on you, the car, where you live and your history, and the higher levels of cover are not always more expensive. Since 1 January 2022, insurers can't charge you more at renewal than they would charge an equivalent new customer.

The legal minimum

Section 143 of the Road Traffic Act 1988 says a person must not use a motor vehicle on a road or other public place unless there is a policy of insurance in force that meets the Act's requirements. It is also an offence to let someone else use your vehicle without that cover.

GOV.UK describes third party insurance as the legal minimum: it covers you if you cause damage or injury to any other person, vehicle, animal or property, but not repairs to your own vehicle.

MoneyHelper adds that if you own a roadworthy vehicle you need at least third party insurance even if you don't drive it. The only exception is if you officially declare it off the road with a Statutory Off Road Notification (SORN).

Penalties for driving uninsured

According to GOV.UK, the police can give you a fixed penalty of £300 and 6 penalty points if you are caught driving a vehicle you are not insured to drive. If the case goes to court, you can get an unlimited fine and be disqualified from driving. The police can also seize, and in some cases destroy, the vehicle. MoneyHelper notes that getting a seized car back means proving you are insured and paying storage fees.

Comprehensive vs TPFT vs third party only

A few points that catch people out:

• Comprehensive isn't always the most expensive. MoneyHelper says third party only can cost more, depending on your claims history and where you live.
• Driving other cars. A comprehensive policy may let you drive someone else's car with their permission, but MoneyHelper says this usually gives you no more than third party cover, so damage to the car you are driving isn't covered if you are at fault. Check your own policy, as terms differ.
• Add-ons. Legal expenses, breakdown, courtesy car and key cover are often sold separately. Some may duplicate cover you already have, for example through a packaged bank account.

Excesses: compulsory and voluntary

The excess is the amount you pay towards a claim. There are usually two parts:

• Compulsory excess, set by the insurer. It can vary depending on the type of claim.
• Voluntary excess, which you choose. Raising it can lower your premium, but you pay both excesses when you claim.

Insurers often ask you to pay the excess up front on a fault claim, so it is worth choosing a total you could actually afford at short notice. It is also worth checking whether a separate excess applies to windscreen claims.

No-claims discount and protection

Your no-claims discount (or bonus) is a reduction you earn for each year without a claim. MoneyHelper says it typically ranges from 30% after one year to 65% or more after five years. If you make a claim, you generally lose two years' worth; more than one claim in a year can wipe it out.

No-claims discount protection is an add-on that lets you make a limited number of claims without losing the discount: MoneyHelper says usually one claim in one year or two in three years. Two points are often misunderstood:

1. It protects the discount, not the price. Your premium can still go up after a claim.
2. Named drivers usually don't build up their own no-claims bonus.

Even if you don't claim, you normally have to tell your insurer about any accident or damage at renewal. Failing to do so can lead to a future claim being reduced or rejected.

Renewal pricing: the FCA's 2022 rules

Before 2022, many insurers raised prices each year for customers who stayed, a practice the FCA called "price walking". In May 2021 the FCA confirmed new rules for home and motor insurance, which took effect on 1 January 2022. Insurers must now offer renewing customers a price that is no higher than they would charge a new customer for the same cover. The rules also made it simpler to cancel automatic renewal.

This doesn't freeze your premium. Prices can still rise at renewal for everyone. But being a long-standing customer should no longer, on its own, cost you more. Comparing your renewal against the market is still worthwhile, because other insurers price differently.

Fronting, ghost broking and other things that void cover

Fronting is when an experienced driver, often a parent, is named as the main driver on a policy, with a less experienced driver added as a named driver, when the less experienced driver actually uses the car most. MoneyHelper says insurers consider this fraud: the person who drives the car most often should be the main policyholder. The result can be a refused claim, a cancelled policy and, in effect, driving uninsured.

Ghost broking is a scam where someone sells you cheap "insurance" by changing your details, such as age, job or driving record, when buying a real policy. The FCA warns these policies are not valid if you have an accident. You can check whether a firm is authorised on the FCA register.

Other common reasons cover is invalidated or claims refused include:

• Wrong class of use: social, domestic and pleasure does not cover commuting; business use needs its own cover
• Undisclosed convictions, penalty points or previous accidents, even ones that were not your fault
• Incorrect occupation or address
• Modifications you didn't declare, such as alloy wheels
• Keys and security: theft claims can be refused if keys were left in or near the car. The Financial Ombudsman Service says absence of a break-in doesn't automatically mean you were careless, and expects insurers to investigate properly.

What changes the cost

Insurers price car cover on factors including your age and experience, where you live and park, your job, annual mileage, the car's insurance group, security devices, claims and convictions history, who else drives, your chosen excess, and whether you pay monthly. MoneyHelper notes that paying monthly can involve interest.

What to check in your policy

• Level of cover: comprehensive, TPFT or third party only
• Class of use: social, domestic and pleasure; commuting; business use
• Named drivers, and who is recorded as the main driver
• Compulsory and voluntary excess, and any separate windscreen or young-driver excess
• No-claims discount: years recorded, and whether it is protected
• Driving other cars: included, and if so at what level of cover?
• Courtesy car: always provided, or only with an approved repairer, and for how long?
• Keys and theft conditions, including keyless entry wording
• Personal belongings, audio and sat-nav limits
• Declared modifications, mileage and overnight parking

When to talk to a regulated adviser

An FCA-regulated insurance broker can help if you are seen as higher risk, for example as a young driver, a driver over 70, or someone with convictions. If a claim is refused, see what to do when an insurance claim is rejected. Vans used for work have different rules on class of use: see van insurance explained.

Common questions

What is the minimum car insurance required by law?

Third party insurance is the legal minimum in the UK. It covers injury or damage you cause to other people, vehicles, animals or property, but not repairs to your own car. Under the Road Traffic Act 1988 you must not use a motor vehicle on a road or other public place without it. A roadworthy vehicle kept off the road needs a SORN instead.

Is comprehensive car insurance always more expensive than third party?

No. MoneyHelper points out that third party only can cost more than comprehensive, depending on your claims history and where you live. Insurers price each level of cover on how risky they think the people who choose it are, so it can make sense to compare all three levels rather than assuming the lowest cover is the lowest price.

What does no-claims discount protection actually protect?

It protects the discount itself, not your premium. MoneyHelper says you are usually allowed one claim in a year, or two claims in three years, without losing your no-claims bonus. Your insurer can still raise the price after a claim, because the claim is part of your history. Without protection, a single claim generally costs two years of bonus.

Can my insurer charge me more at renewal than a new customer?

Not for the same cover. FCA rules in force since 1 January 2022 require home and motor insurers to offer renewing customers a price no higher than they would charge an equivalent new customer. Your premium can still rise at renewal, for example because of claims or wider cost increases, but there should be no loyalty penalty for staying.

What is fronting and why does it matter?

Fronting is when a policy is taken out with an experienced driver, often a parent, named as the main driver when someone else, often a young driver, actually drives the car most. Insurers treat this as fraud. It can mean a claim is refused, the policy is cancelled and the driver is effectively uninsured, with possible criminal consequences.

What happens if I drive without insurance?

According to GOV.UK, the police can give you a fixed penalty of £300 and 6 penalty points. If the case goes to court you can get an unlimited fine and be disqualified from driving. The police can also seize, and in some cases destroy, a vehicle being driven uninsured.
