What is the Group Rating system?

Car insurance groups are decided by the Group Rating Panel, supported by Thatcham Research. The panel decide which insurance group new car models should fall into. Group one being the cheapest to insure, to group 50 – the most expensive to insure.

According to the Association of British Insurers (ABI), the cost of car repairs take up more than half of insurance pay-outs, which is why repair costs are a strong factor when determining grouping.

Our own data (collated July – Dec 2016) has shown some of the cheapest cars to insure fall into groups one to three, including the Skoda Yeti, Fiat Qubo and Citroen Berlingo.

Low insurance group cars list

The cheapest cars to insure are those vehicles which are relatively inexpensive to buy – usually low-specification models with smaller engines. You could expect to find cars such as the Toyota Yaris, Vauxhall Corsa, Kia Rio and Dacia Sandero among the cheapest to insure.

We’ve crunched the numbers and below is a breakdown of some of the cheapest cars to insure depending on which age group you fall in to.

What factors contribute to grouping?

Cars are assigned to their insurance group based on a number of factors. These include:

Damage and parts costs - The likely extent of damage to each model and the price of the parts involved. Lower costs usually mean a lower group rating.

Repair times - Longer repair times mean higher costs and a higher group rating. According to Thatcham Research, over half of all money paid out in motor insurance claims goes on repairing cars - so the cost of spare parts and repair times are major factors in pricing motor insurance.

New car values - New car prices provide a guide to replacement and repair costs.

Parts prices - A list of 23 common parts is used to compare one manufacturers' parts costs to another.

Performance - High performance cars are at higher risk of frequent insurance claims, so the acceleration and top speed of vehicles are taken into account.

Safety - Vehicles fitted with an AEB - Autonomous Emergency Braking systems - will avoid 'low speed front to rear' accidents and so could benefit from a lower insurance group rating.

Bumper compatibility - The alignment and structure of bumpers can help a car to receive a lower insurance rating.

Car security - Cars with security features, such as alarm/immobilisation systems and high security door locks, could see a lower insurance group.

Cutting the cost of car insurance

Buying a vehicle that is in one of the lower car insurance groups is one of the best ways to cut the cost of your policy. 

However, if you already own a car which isn't among the cheaper models and want to reduce the price of your policy, there are still a number of steps you can take.

  • Adding security-enhancing systems, such as recognised and approved immobilisers and alarms, is a simple way of reducing costs. Such devices will make your car more secure and therefore reduce the statistical chances of you making an insurance claim.
  • You could also choose to pay a higher voluntary excess - the amount you contribute in the event of a claim - which will usually mean a lower premium. 
  • If you're prepared to pay your annual insurance policy up front and in one lump sum, this could work out cheaper than arranging monthly direct debit payments. Insurers often charge interest on monthly payments.
  • Choosing to include just the essentials of a policy and not adding optional extras - such as having the use of a courtesy car if yours is unavailable for a certain time for any reason, like an MOT, repairs or service - will also keep costs down.
  • New and young drivers might consider a black box insurance policy. This uses a satellite tracker to monitor how well the car is being driven. By measuring speed, acceleration and braking, this technology gives insurers a more detailed picture of the risk a driver poses. In short, safer and considerate drivers can be rewarded with lower insurance premiums.
  • Equally, one of the best ways to find the best value insurance policy for you is to shop around and compare cheap car insurance quotes from a number of providers.
