Car insurance groups

Car insurance groups are one of many factors used to determine the risk insurers face when covering a particular car.  Typically, the higher the insurance group, the higher the premium as cars found in higher groups will be more expensive to repair or replace.

• Every private car in the UK is allocated an insurance group which is then used by insurers alongside things like your address and driving history, to calculate your insurance premium
• There are 50 different insurance groups ranging from 1 to 50 with 1 usually being the cheapest to insure and 50 being the most expensive
• The motor insurance repair research centre Thatcham is responsible for working in conjunction with the Association of British Insurers to allocate a group to each new car

Some of the models you may find within the different insurance groups include:

How many car insurance groups are there?

Thatcham introduced the 1-50 system in 2007. This means that each model of car tested can be banded more accurately with similar cars. The 50 different groups are determined by a number of factors that your car will fall under. For insurance companies, this serves as a recommendation or guide for when preparing a new policy and price for a customer.

There are many factors that go into determining which insurance group a car should be placed in. One of the biggest factors is the repair costs involved following an accident. Over 50% of the money paid out in car insurance claims goes towards the cost of repairs, according to figures from the ABI (based on research collated from May 2015).

But this isn't the only factor that's considered when groups are allocated. Typically, cars that cost more to repair become more of a risk for insurers to cover.

Factors that affect the grouping of a car include:

• Performance: A car's 0-60mph time and top speed can influence the insurance group. High-performing cars typically have more frequent insurance claims.
• New car price: Newer, more expensive cars tend to be more costly to replace.
• Parts pricing: This is the assessment of the extent of damage that a car model might incur, and the cost of the parts involved in its repair.
• Security: Enhanced security features help protect your vehicle against thieves, and may also help the car be placed in a lower insurance group.
• Average repair time: Long repair times could mean a higher insurance group rating and higher costs as a result.
• Car bumper: The performance of a bumper in an accident can also affect how the car is grouped.
• Body shell: Group ratings can be affected by the availability of body shells in addition to parts, because they may well be required in the repair of damage to a car.

When allocating a group rating for a car, if the cars’ security features have been rated, the insurance group number (rated from 1 to 50) is followed by a letter showing the result of the security test:

Although car insurance groups are just one of the factors involved in calculating the price of insurance, it’s generally accepted that those cars in a higher group will result in a higher insurance premium, which is why if you’re looking to reduce the cost of your insurance, you could consider a car that falls into a lower insurance group.

If you’d like to check the insurance group of your car, you can do so on the Thatcham website. The proposed groupings are recommendations only, and hence are not binding on insurers, who can set their own groupings if they choose.

• Different types of cover - traditionally many drivers think of third party as being the cheapest level of cover, but sometimes it can be cheaper to opt for a comprehensive policy. Be sure to compare different policy types like telematics, comprehensive or third party fire and theft to help you find the policy that meets your needs and budget the best.
• Increase your excess - increasing the amount of voluntary excess you're willing to pay toward any claim may reduce your quote price.
• Fit extra security - an additional security device such as an immobilizer or tracker could help reduce the chance of your car being stolen which understandably, is a positive thing to insurance companies.
• Be accurate with your mileage estimation - over exaggerating your annual mileage could end up costing you more. Try and be as accurate as you can when calculating your mileage during the quote. There's no need to pay extra for miles you're not driving.

It's also important to be clear to your insurance company who the main driver of the car is. Not telling the truth about who the main driver is, could invalidate or void any claim you make.
