When you’re looking for car insurance, you’ll often see vehicles described by an ‘insurance group’. This number is meant to give insurers a quick idea of how expensive a car might be to insure. The system has been around for a long time, but it’s changing. Understanding how these groups work, and what’s coming next, can help you make better choices when buying a car and getting quotes.
The current system, which has been in place for over 25 years, uses a scale from Group 1 to Group 50. Group 1 cars are generally the cheapest to insure, while Group 50 cars are the most expensive. This rating is determined by a panel that looks at various factors. These include how much the car’s parts cost to replace, its performance capabilities, the security features it has, and its safety ratings. Cars with cheaper parts, slower acceleration, good security, and strong safety scores tend to land in lower groups, which usually means lower insurance premiums. Here’s what you actually need to know.
Understanding Car Insurance Groups
The car insurance group system is a way to categorise vehicles based on their potential cost to insure. Think of it as a shortcut for insurers. A vehicle’s group rating is determined by the Group Rating Panel. They assess several key aspects of a car. These include the cost of its parts, how expensive it is to repair, its performance figures like acceleration, and the effectiveness of its security and safety features.
For example, a small, economical car with readily available and inexpensive parts, and modest performance, will likely be placed in a low group. This means it’s generally cheaper to insure. On the flip side, a powerful sports car with specialised, costly parts and a higher risk of theft or damage will be in a high group, making insurance more expensive. If I were choosing between two similar cars and one was in Group 5 and the other in Group 15, I’d lean towards the Group 5 car because it signals potentially lower insurance costs, which is a practical saving I could make.
Why Car Insurance Groups Matter to Drivers
The insurance group assigned to a car directly impacts the premiums you’ll pay. A vehicle in a low group, such as Group 1, might cost around £500-£700 annually for a standard driver. However, a vehicle in Group 50, like a supercar, could see annual premiums soar to £2,000-£5,000 or even more. This significant difference highlights why the group rating is so important for your budget.
The system’s reliance on historical data and fixed categories means it hasn’t always kept pace with automotive advancements. For instance, the rise of electric vehicles (EVs) and cars equipped with advanced driver-assistance systems (ADAS) presents new challenges. These vehicles often have different repair costs and safety profiles than traditional petrol or diesel cars. The existing system is used by brokers and price comparison sites, who combine it with driver-specific details like claims history to calculate car insurance premiums. This means the group rating is just one piece of a larger puzzle.
Understanding these groups helps you anticipate insurance costs. If you’re looking at a car that falls into a high group, you should be prepared for potentially much higher insurance quotes. This is especially true if you’re a younger driver or have a less-than-perfect driving record, as these factors also increase premiums on top of the car’s group rating. I would always check the insurance group of any car I was considering buying, as it’s a straightforward way to get an early indication of potential running costs.
Common Misconceptions About Insurance Groups
Assuming Group Rating is the Only Factor
One of the biggest misunderstandings is that the insurance group is the only thing that determines your premium. While it’s a major factor, insurers also consider many other details. These include your age, driving experience, where you live, your annual mileage, and your no-claims bonus. A car in a low group might still be expensive to insure for a new driver with no experience. The system is used by brokers and price comparison sites, who combine it with driver-specific details to calculate premiums.
Believing Group Ratings Never Change
While the system has been stable for a long time, it is undergoing a significant overhaul. The longstanding 1-50 car insurance group rating is being replaced. This change is necessary due to the increasing complexity of modern vehicles. The old system has been in place for over 25 years, having replaced the older 1-10 groups.
Ignoring the Impact of New Technology
The current system doesn’t fully account for the impact of new technologies. This includes the growing number of electric cars and vehicles fitted with advanced driver-assistance systems (ADAS). These systems can affect accident frequency and severity, as well as repair costs. The need for a modernized system arises from the increase in electric cars, advanced driver assistance systems (ADAS), and software-driven features.
Thinking All Cars in the Same Group Cost the Same to Insure
Even within the same insurance group, two different car models can have different premiums. This is because insurers use the group rating as a starting point. They then apply their own specific risk assessments and pricing models. The new ‘Vehicle Risk Rating’ (VRR) system is already live and will be used alongside the existing group rating for an 18-month dual-rating period. This suggests that more detailed assessments are coming.
If I were comparing two cars that fell into the same insurance group, I’d still get quotes for both. I’d want to see if there were any unexpected differences in pricing. It’s a practical step to ensure I’m getting the best deal, as the group rating is just one part of the equation.

The Future: Vehicle Risk Rating (VRR)
The car insurance group system is undergoing a significant change. The traditional 1-50 group rating is being replaced by a new approach called ‘Vehicle Risk Rating’ (VRR). This new system is designed to be more modern and accurate. It covers five key areas: performance, damageability, safety, security, and repairability. The goal is to provide a more detailed assessment of a vehicle’s risks.
This shift is driven by the rapid evolution of car technology. Electric cars, with their different battery systems and repair needs, and vehicles equipped with advanced driver-assistance systems (ADAS) require a more sophisticated rating method. The new VRR system is designed to provide more granular data that accounts for technological advancements, emerging theft trends, and a greater focus on sustainable and affordable repair. Thatcham Research states that new technology is altering the motor insurance model, shifting the balance of risk from the driver to the vehicle.
A key change is that car insurance ratings will no longer simply rely on an insurer’s historical experience of a vehicle type. Instead, the VRR system will offer a more precise and detailed assessment of vehicle risks. This will assist insurers in pricing premiums more accurately. The new system will also factor in the influence of fast-developing ADAS systems on accident frequency and severity. It will also consider how new technology helps combat criminal gangs and how EVs and new vehicle structures affect sustainable repair.
For drivers, this means that insurance pricing might become more nuanced. A car that was previously in a high group due to older technology might see its rating change under the new system if its modern safety or security features are deemed to reduce overall risk. Conversely, a car with advanced, complex systems that are expensive to repair could see its rating increase. If I were buying a new car with a lot of advanced tech, I’d want to understand how the new VRR system might affect its insurance cost, even during the dual-rating period.

Making Informed Decisions with New Ratings
Understanding the New VRR Factors
The VRR system breaks down vehicle risk into five core areas. These are performance, damageability, safety, security, and repairability. Each of these will be assessed to give a more precise rating. For example, a car’s performance might be evaluated not just on speed, but on how its power delivery could contribute to accidents. Damageability will look at how easily the car sustains damage in a collision and the cost of repairs. Safety will consider crash test results and the effectiveness of active safety systems. Security will focus on anti-theft measures, and repairability will assess the cost and complexity of fixing the vehicle after an incident.
Comparing the Old and New Systems
The old 1-50 group system was a broad classification. The new VRR system aims for much greater detail. For instance, the old system might have put all SUVs in a similar bracket. The new system could differentiate based on specific safety features, the cost of replacing advanced sensors, or the repair complexity of their chassis. The new system will also consider the impact of rapidly developing ADAS systems on accident frequency and severity. This granular approach means that two cars that were previously in the same insurance group might now receive different VRR ratings.
Considering the Dual-Rating Period
For an 18-month period, both the old 1-50 group rating and the new VRR system will be in use. This dual-rating approach allows the industry to transition smoothly and for drivers to become familiar with the changes. Insurers will use both sets of data to calculate premiums. This means you might see quotes that reflect both the traditional group number and the new VRR assessment. It’s important to understand that the VRR is intended to be a more accurate reflection of risk.
How to Use This Information When Buying a Car
When you’re looking to buy a car, especially during this transition period, it’s wise to check both the insurance group and any available VRR information. If you’re buying a new car, the manufacturer or insurer may be able to provide details on its VRR assessment. If you were looking at a car that previously had a high insurance group, but the new VRR assessment suggests lower risk due to advanced safety features, it could lead to more affordable insurance. My first move would be to check the insurance group for any car I’m interested in, and then actively seek out information on its VRR assessment if available, as this will give me the most up-to-date picture of potential insurance costs.
- 1Check the Insurance GroupBefore buying, find out the car’s current insurance group rating (1-50). This gives you an initial idea of potential costs.
- 2Inquire about VRRFor newer vehicles, ask about their Vehicle Risk Rating (VRR) assessment. This newer system provides a more detailed risk profile.
- 3Get Multiple QuotesAlways get insurance quotes from several providers. Premiums can vary significantly based on the insurer’s specific risk assessment and your personal details.
- 4Consider Security FeaturesVehicles with enhanced security features, such as alarms or tracking devices, may benefit from lower premiums. A Garmin Dash Cam X310 could potentially help by recording incidents.
