Warranty insurance: is it worth it?

A car warranty covers you against electrical and mechanic failures over an agreed period – typically three years or 60,000 miles. It brings peace of mind by covering the costs of labour and parts when the worst happens. However, policies vary, and you need to pick the right one – here’s what you need to know.

The pros and cons of car warranty insurance

Here are the main pros and cons when it comes to taking out car warranty insurance:

How much does it cost?

The price of your warranty depends on your insurer, so compare quotes to find the best deal.

Most insurers offer three levels of cover, with basic policies being cheaper and premium cover costing more. The cost of warranty insurance is also based on:

• The age of the car

• The make and model

• The value of the car

• Your annual mileage

• How your car is used, eg for social or business

Cheaper warranties usually provide less cover, so you may need to spend more to get the protection you want. But check that the cost of a warranty is not more expensive than paying the cost of repairs yourself.

What if your mileage is high?

You may struggle to find a warranty if you have a second-hand car, or a classic car with high mileage.

There are specialist policies, but they tend to be expensive so it’s even more important to shop around for the best deal.

What does warranty insurance cover?

Policies vary by insurer, but a typical vehicle warranty policy covers repairs to the:

• Engine

• Transmission system

• Fuel and ignition system

• Air conditioning or cooling system

• Electrics

• Gearbox

• Steering

• Suspension

• Non-frictional clutch and brakes

It is important to check your documents because exclusions may restrict what you can claim for. For example, some insurers cover electrics but not in-car stereo systems. Read the terms and conditions carefully, and make sure when you’re selecting a policy it covers all the components you need.

As well as cover for repairs, your cover may also include:

• Vehicle breakdown recovery

• Car hire, while yours is being fixed

• Hotel expenses for overnight stays while repairs are carried out

• Emergency travel expenses, e.g. taxis, trains or buses

• Driving your car abroad

Cover levels vary widely depending on the policy you choose, so check the insurer's summary of cover before you buy.

Beware of conditions

Warranties come with conditions that mean your cover is invalidated if they are not met, like:

• Age limit: Cars older than 10 years are usually not covered

• Mileage limit: For example, no more than 60,000 miles

• Claim limit: This is the most your insurer will pay for repairs, usually the value of the car

• Pre-existing faults: Problems that were there before your policy started are not covered

• Warning lights: You cannot claim if you have ignored warnings of a problem

• Maximum hourly rate: This is the most your insurer will pay for labour costs

• Regular servicing and MOT: This must be recorded by an approved garage

• Insurer authorisation: Repairs must be approved before claims are paid

• Authorised garages: All repairs must be carried out at a garage approved by your insurer

• Car modifications: Any changes to the original vehicle may void your insurance

• Maintenance: You must look after your car in line with the manufacturer's handbook

• Time limit for claims: You must tell your insurer of any problems within seven days

Read the insurer's policy documents for a full list of conditions before you pay for cover. If you fail to meet them, your insurer can refuse to pay your claims.

What is excluded?

Exclusions vary between insurers but some of the things that are often excluded by a car warranty policy are:

• General wear and tear (you may be able to include this for an added price)

• Batteries, wheels, tyres, exhausts, catalytic converters, worn-out clutches and brakes

• Damage caused by oil leaks

• Cars used for competitions, commercial deliveries or as taxis

• Improvements to parts that are not broken

• Damage caused by frost, worn friction materials, blockages, contamination or sludge

• Poor workmanship or faulty components

Check policy documents when you compare warranty insurance. Think about the car you drive and what is likely to go wrong. Make sure you select a policy that meets all your needs, even if it’s slightly more expensive. The alternative is costly insurance that won’t pay out.

Are you already covered?

You may not need separate cover if you already have a manufacturer's warranty in place.

• New cars: All new cars come with a manufacturer's warranty, usually lasting between 3 and 7 years.

• Used cars: If you buy your car from a second-hand car dealership, it may come with a 12 month warranty. You could also look for a used car that is still within its manufacturer's warranty, which could last up to 7 years.

Check your purchase documents to see if your car is still under its manufacturer's warranty before you buy insurance.

Do you need a warranty?

This depends on whether you can afford the costs of repairing your car yourself.

You may find the price of a warranty is more than the cost of paying for repairs, in which case you should avoid paying the unnecessary price of insurance.

However, warranty insurance could save you money if your car needs expensive repairs.

Many warranties also include breakdown cover, which means you don’t need to buy it separately, so you should factor that into your calculation too.

Where can you get cover?

You may be offered a warranty by the dealership where you buy your car, but this is usually the most expensive way to get cover. 

Instead, compare as many different quotes as possible and always read the small print in the policy documents. This will help you find the right policy for your car.
