In the realm of motor insurance, understanding the nitty-gritty of how car insurance groups work is essential. Car insurance group is a rating system assigned to vehicles based on various factors, including repair costs, safety features, and performance metrics. It is a fundamental component in determining the cost of your insurance premium.

Car insurance groups use a lettering system to indicate the level of safety provided by a car. But how exactly do these groups function? Let’s delve into the specifics.

What are car insurance groups?

Car insurance groups are a significant factor in determining the cost of your car insurance policy. A car’s insurance group is important in determining insurance premiums.

Every vehicle available in the market is assigned a specific insurance group ranging between 1 to 50, with group 1 consisting of the cheapest cars to insure and group 50 being the most expensive.

The categorisation is primarily based on a system developed by the Association of British Insurers (ABI) and Lloyds Market Association, with the assistance of Thatcham ResearchA car’s insurance group rating is influenced by factors such as engine size and safety features, and these ratings help insurers assess the risk level associated with different car models.

How are car insurance groups calculated?

Car insurance groups are meticulously calculated by the Group Rating Panel, a team of experts from the insurance industry. This panel includes members from the Association of British Insurers (ABI) and Thatcham Research, who use a comprehensive rating system to evaluate over 100 individual data points for each vehicle.

These data points encompass various factors such as repair costs, security features, safety features, and vehicle performance. By assessing these elements, the panel can determine the insurance group rating for each car, ensuring a more accurate reflection of the diverse range of vehicles available in the UK market. This detailed evaluation helps insurers set premiums that align with the risk associated with each car model.

The role of ABI group rating system

The ABI Group Rating System plays a crucial role in determining how car insurance groups work. The system is designed to provide insurance providers with the necessary information to calculate premiums for different car models accurately.

Several factors come into play in this system. These include:

  • The vehicle’s value
  • The cost of replacement parts
  • The time taken for repairs
  • The vehicle’s performance
  • The safety features of the car
  • The car’s security

Understanding the letters in car insurance groups

In addition to the numbering system, car insurance groups also incorporate a lettering system, which is used to denote the level of safety provided by the car. The following are the interpretations for each letter:

  • A: The car meets the standard requirements for its group.
  • D: The car does not meet the standard requirements for its group and is therefore placed in a higher insurance group.
  • E: The car exceeds the standard requirements for its group and is consequently placed in a lower insurance group.
  • P: The car’s data is provisional as the rating system was incomplete at the time of its launch.
  • U: The car’s security level is below the required standard. While it can still be insured, the insurer might require additional security features to be installed.
  • G: The car is imported. Imported vehicles are categorised into two groups – parallel imports and grey imports.

Factors that affect a car’s insurance group rating

Several key factors influence a car’s insurance group rating, impacting the cost of your car insurance premiums:

  • Engine size: Vehicles with smaller engines typically fall into lower insurance groups due to their reduced risk of accidents. Conversely, cars with larger engines are often placed in higher insurance groups because they are considered more likely to be involved in high-speed incidents.

  • Performance: High-performance cars, known for their speed and acceleration, are generally assigned higher insurance group ratings due to the increased risk of accidents.

  • Safety and security equipment: Cars equipped with advanced safety and security features, such as airbags, anti-lock braking systems (ABS), and immobilisers, can benefit from lower insurance group ratings. These features reduce the likelihood of accidents and theft, making the vehicle less risky to insure.

  • Limited-run cars: Vehicles that are produced in limited numbers and have hard-to-source parts can be placed in higher insurance groups. The potential for longer repair times and higher repair costs increases the risk for insurers.

  • Electric cars: While electric cars often have higher repair costs, placing them in higher insurance groups, their growing popularity and advancements in technology may lead to more favourable insurance group ratings in the future.

How vehicles are grouped for insurance

While understanding how car insurance groups work, it’s imperative to know the factors that influence the grouping of vehicles for insurance. The following are the primary considerations:

  • Vehicle valuation: The car’s price and the cost of settlement in case of a total write-off are taken into account. The type of the car also influences its grouping. For instance, high performance cars of a certain value are likely to be placed in a higher insurance group compared to an estate car of the same value due to the assumed driving behaviour.
  • Cost of repair: A globally recognised standard crash impact test is used to assess the repair times and cost of a vehicle. The results are recorded and used to estimate accident damages, repair times, and part costs for insurance purposes.
  • Vehicle performance: The performance of the car is assessed by measuring its acceleration from 0 to 60 mph and its top speed. More powerful vehicles are placed in higher insurance groups.
  • Safety technologies: Cars equipped with the latest safety technologies such as autonomous emergency braking are less likely to be involved in an accident, and therefore, are often placed in lower insurance groups.
  • Cost of spare parts: The cost and availability of 23 common vehicle parts are used to compare the car with similar models from other manufacturers. Cars that are cheaper and quicker to repair are placed in lower insurance bands.
  • Vehicle security: Vehicles with higher security features are harder to steal or break into, thus placing them in lower insurance groups.
  • Bumper compatibility: Cars with bumpers compatible with the criteria of the ABI’s Group Rating System are categorised into lower insurance groups.

Popular insurance groups

To provide a clearer understanding of how car insurance groups work, let’s explore some of the most common insurance groups:

  • Insurance group 1-10: This group features cars with the lowest insurance costs. These vehicles usually have smaller engine sizes and low costs of repairs, making insurance costs more affordable. Typical cars in this group include the Toyota Aygo, Vauxhall Corsa, and Fiat 500.
  • Insurance group 10-20: This group consists of vehicles with reasonable but slightly higher costs. Common cars in this group include the Mazda 2, Renault Clio, and Ford Fiesta.
  • Insurance group 20-30: This is a mid-range insurance group. Cars in this group are slightly more costly to insure but offer a balance between performance and practicality. Examples include the Suzuki Swift and Ford Kuga.
  • Insurance group 30-40: This group is dominated by performance-oriented vehicles and more expensive cars. Examples include the BMW 3-Series and Audi A5.
  • Insurance group 40-50: The highest insurance group consists of powerful and prestigious vehicles, including luxury vehicles and top-spec SUVs. Examples include the Jaguar XF, BMW 5-Series, and Audi TT.

Insurance groups for a van

Insurance groups are not exclusive to cars; vans also have their own group ratings, which can affect insurance premiums. Vans produced before 2017 are categorised into one of 20 groups, while those manufactured after 2017 fall into groups 1-50, similar to cars.

How to lower your car insurance

Understanding how does car insurance groups work is just one part of the puzzle. Here are some tips to help you lower your car insurance premiums:

  • Voluntary excess: Increase your voluntary excess to reduce your annual premium.
  • No claims bonus: The longer you go without making a claim, the lower your premium will be.
  • Drive less: Reducing your annual mileage can lower your car insurance costs.
  • Pay annually: Paying your premium annually instead of monthly can save you money as insurance providers often charge interest on monthly payments.
  • Car storage: Storing your car in a secure location like a garage can help lower your premiums.
