What Insurance Group Is My Car? A Comprehensive UK Guide

Summary

• Every car in the UK is assigned to one of 50 insurance groups, with Group 1 being the cheapest to insure and Group 50 the most expensive.
• You can find your car's group instantly online using its registration number or make, model, and year.
• Key factors determining the group include the car's value, repair costs, performance, and its safety and security features. A letter suffix (e.g., 'E' or 'D') indicates how the car's security compares to the standard.

How to Find Your Car's Insurance Group

The quickest and most accurate way to find your car's insurance group is to use an online checker. Most tools are free and provide an instant result.

You will typically need one of the following:

• Your car's registration number (VRN): This is the easiest method.
• Your car's make, model, and year: If you don't have the registration number, you can usually find the group by providing these details.

Many major insurance comparison sites and automotive resources offer these tools. Once you enter your details, the tool will reveal your car's specific insurance group number.

Understanding the UK Car Insurance Group System

In the UK, all cars are placed into one of 50 insurance groups. The system is straightforward:

• Group 1: Contains the cheapest cars to insure.
• Group 50: Contains the most expensive and high-performance cars to insure.

This system, administered by Thatcham Research on behalf of the Association of British Insurers (ABI) and the Lloyds Market Association (LMA), helps insurers calculate the risk associated with a particular vehicle. A dedicated Group Rating Panel meets monthly to assign groups to new car models.

Until 2009, there were only 20 groups. This was expanded to 50 to allow for more precise and fairer ratings, ensuring cars with similar characteristics are banded together more accurately.

Key Factors That Determine a Car's Insurance Group

Thatcham Research assesses several key factors when assigning a car to an insurance group. It's not just about speed; it's a detailed analysis of potential costs for the insurer.

1. New Car Value

The price of the car when new is a primary factor. A more expensive car costs more to replace if it's written off, leading to a higher insurance group. You can learn more by checking your car's value.

2. Repair Costs and Times

This is a critical part of the assessment. Thatcham Research analyses:

• The cost of common parts: How much do bumpers, headlights, and body panels cost?
• Repair labour times: How long does it take to fix typical accident damage? Cars that are complex or time-consuming to repair will be placed in higher groups.

3. Performance and Engine Power

A car's performance capabilities directly influence its risk profile. Insurers look at:

• Acceleration (0-60 mph): Faster cars are statistically more likely to be involved in accidents.
• Top speed: High-performance vehicles are placed in higher groups.
• A guide on car engine sizes can provide more context on how this impacts performance.

4. Safety Features

Modern safety technology can help reduce the frequency and severity of accidents. Cars equipped with advanced systems may be placed in a lower group. Key features include:

• Autonomous Emergency Braking (AEB): Can automatically brake the car to prevent or mitigate a collision.
• Lane Departure Warnings: Alert the driver if they are drifting out of their lane.
• Electronic Stability Control (ESC): Helps prevent skidding.

5. Security Features

The better a car's security, the lower the risk of it being stolen. This can result in a lower insurance group. Insurers value factory-fitted:

• Alarms and Immobilisers: These are standard on most new cars and deter theft. You can learn more about what immobiliser your car has.
• High-security door locks.
• Visible VINs (Vehicle Identification Numbers).
• Tracking systems.

Decoding the Letters in Your Insurance Group

Sometimes, you'll see a letter after the insurance group number (e.g., 21E). This letter provides extra information about the car's security standards.

Letter	Meaning	Impact on Insurance
E	Exceeds	The car's security is better than the standard required for its group. This is a positive rating and can result in a lower premium.
A	Acceptable	The vehicle meets the required security standard for its group.
D	Doesn't Meet	The car's security is below the requirement for its group, so its rating has been increased (e.g., a group 19 car might become a 20D).
U	Unacceptable	The car has unacceptably poor security. An insurer may require you to fit additional security systems before offering cover.
P	Provisional	A provisional rating given when a new car is launched and complete data isn't yet available. This may be updated later.
G	Grey Import	The car has been imported outside of official manufacturer channels. Insuring these can be more complex. Check out our guide on imported vehicles.

How the Insurance Group Affects Your Premium

A car's insurance group is a major factor in determining your premium, but it's not the only one. Insurers use it as a starting point and then combine it with personal factors to calculate your final price.

Generally, a lower insurance group number leads to a cheaper premium.

However, insurers also consider:

• Your Age: Younger, less experienced drivers typically pay more.
• Your Driving History: A history of claims or driving convictions will increase your premium.
• Your No-Claims Bonus: A long no-claims history significantly reduces costs.
• Your Location: Premiums are higher in areas with more traffic or higher rates of vehicle crime.
• Your Occupation: Some jobs are considered higher risk than others.
• Annual Mileage: The more you drive, the higher the risk of an accident.

Examples of Cars in Different Groups

To give you an idea, here are some examples of cars and the insurance groups they often fall into:

• Low Groups (1-10): Ideal for new drivers and city driving. Examples include the Citroën C1, Fiat Panda, Hyundai i10, and Volkswagen Up!
• Mid-Range Groups (20-35): Typically includes popular family hatchbacks and SUVs like the Ford Focus, Nissan Qashqai, and performance models like the VW Golf GTI.
• High Groups (40-50): Reserved for luxury, high-performance, and premium sports cars such as the Porsche 911, Range Rover Sport, and high-end Teslas.

Before buying any car, it's wise to perform a free car check to understand its full history, including its MOT and tax status, which can also impact your decision.
