When shopping for car insurance in the UK, you might come across the term car insurance groups. Every vehicle is placed into an insurance group, which helps insurers determine how much you’ll pay for cover. But how do these groups work, and what do they mean for your premiums? This guide will explain everything you need to know about car insurance groups, how they are assigned, and how they affect your insurance costs.
What Are Car Insurance Groups?
Car insurance groups are categories used by insurers to determine the risk level and cost of insuring a vehicle. In the UK, cars are classified into 50 insurance groups, with Group 1 being the cheapest to insure and Group 50 the most expensive.
The lower the group number, the cheaper the car is to insure, as it is considered lower risk. Conversely, cars in higher groups are more expensive to repair, have higher performance levels, or are more prone to theft, leading to increased premiums.
Who Sets Car Insurance Groups?
Car insurance groups are set by the Group Rating Panel, which consists of members from the Association of British Insurers (ABI) and Thatcham Research. They assess each vehicle based on several key factors to determine its insurance group.
What Factors Determine a Car’s Insurance Group?
Several factors influence which insurance group a car falls into. The most important ones include:
1. Vehicle Value
Expensive cars typically cost more to repair or replace, placing them in a higher insurance group.
2. Repair Costs and Times
Cars that require specialist parts or take longer to repair are placed in higher groups, as they pose greater costs to insurers.
3. Performance and Power
High-performance cars with larger engines and faster acceleration speeds tend to fall into higher groups because they have a greater risk of accidents.
4. Safety and Security Features
Cars equipped with advanced safety features, such as collision prevention systems and automatic braking, often qualify for lower insurance groups as they reduce accident risk. Likewise, vehicles with high-security ratings (e.g., immobilisers, alarms) are less likely to be stolen, leading to lower premiums.
5. Vehicle Weight and Size
Larger vehicles can cause more damage in an accident, sometimes leading to higher group ratings.
6. Claims Data and Risk Statistics
Historical claims data helps insurers determine which models are more likely to be involved in claims, affecting the insurance group placement.
How Do Car Insurance Groups Affect Premiums?
Your car’s insurance group directly affects how much you pay for insurance. Here’s how:
Lower insurance groups (1–10): These cars have lower premiums as they are cheaper to repair, have good safety records, and are low-risk.
Mid-range groups (11–30): These cars have moderate insurance costs, with reasonable repair costs and safety features.
Higher insurance groups (31–50): These vehicles have higher premiums, often due to high performance, expensive parts, and greater accident risks.
How to Find a Car in a Low Insurance Group
If you want to save money on car insurance, consider choosing a car in a lower insurance group. Here’s how:
Use Online Car Insurance Group Checkers – Websites like Thatcham Research and insurer platforms allow you to check which group a vehicle belongs to.
Choose a Smaller Engine – Vehicles with 1.0L–1.2L engines are often placed in lower insurance groups.
Look for Cars with Strong Safety Ratings – Cars with high Euro NCAP safety ratings tend to be cheaper to insure.
Avoid High-Performance Cars – Sports cars and luxury models often fall into higher insurance groups.
Consider Security Features – Having factory-fitted alarms, immobilisers, and tracking devices can help reduce your premiums.
Common Questions About Car Insurance Groups
1. How Can I Check My Car’s Insurance Group?
You can check a car’s insurance group using tools from Thatcham Research, insurer websites, or comparison sites.
2. Do All Insurers Use the Same Groups?
Most insurers use the ABI’s insurance group system, but each provider may also have their own risk assessment methods.
3. Can Changing My Car’s Features Affect Its Insurance Group?
Yes, modifications such as engine tuning, body kits, or alloy wheels can increase the insurance group and premium costs.
4. Does a Lower Insurance Group Always Mean Cheaper Insurance?
Not always. Other factors such as your driving history, location, and no-claims discount also impact the overall cost of insurance.
5. What Are Some of the Cheapest Cars to Insure?
Some cars commonly found in low insurance groups (1–5) include:
Ford Fiesta (1.0L models)
Volkswagen Polo (small engine versions)
Hyundai i10
Vauxhall Corsa (entry-level models)
Skoda Fabia
