Understanding car insurance groups is a crucial first step for any motorist in the United Kingdom looking to secure an affordable premium. These groups, ranging from 1 to 50, act as a foundational guide to how much a vehicle might cost to insure. Group 23 sits comfortably on the more affordable end of this spectrum, making cars within this category highly attractive to budget-conscious drivers. But what exactly does being in Group 23 entail, and what factors contribute to these potentially lower costs? This comprehensive guide will delve into the specifics of insurance Group 23, exploring common vehicles, average costs, and the myriad of other elements that influence your final insurance premium.

Before any new vehicle hits the showrooms, it undergoes a meticulous assessment process to assign it an insurance group. This crucial classification, determined by the Group Rating Panel administered by Thatcham Research, places vehicles into one of 50 categories. Group 1 represents the absolute cheapest cars to insure, while Group 50 signifies the most expensive. Therefore, finding a vehicle in insurance Group 23 means you're looking at a car that is generally among the most economical to insure, offering a sweet spot between affordability and desirable features.
The primary reason cars in insurance Group 23 tend to be cheaper to insure stems from their inherent characteristics and how they perform against the criteria used for group ratings. These vehicles typically score well across several key metrics. Firstly, they often have a lower market value, meaning that in the event of a write-off or significant damage, the cost to replace or repair the vehicle is less substantial for the insurer. Secondly, safety is a paramount consideration; cars in this group usually boast excellent car safety ratings, often achieving maximum scores in independent crash tests like Euro NCAP. This reduces the likelihood and severity of injuries in an accident, thereby lowering potential payout costs for personal injury claims. Thirdly, strong security features, such as factory-fitted alarm systems and immobilisers, are common. These features deter theft, which is a significant factor in insurance claims. Finally, the cost and availability of replacement parts play a role; vehicles in Group 23 often have parts that are inexpensive to source and repair, further reducing potential claim costs. Their engines also tend to be smaller and less powerful, which not only contributes to fuel efficiency but also implies a lower risk of high-speed accidents and less expensive repair or replacement costs for the engine itself.
A diverse range of popular car makes and models fall into insurance Group 23, offering drivers a variety of choices without breaking the bank on premiums. These vehicles often combine practicality, reliability, and good safety standards, making them excellent choices for families, commuters, and those seeking value. Here are some of the more popular vehicles you might find in this advantageous insurance group:

While the insurance group provides a general indication of cost, the actual premium you pay for a Group 23 car can vary significantly based on a multitude of personal factors. Our research suggests that, on average, insuring a car in insurance Group 23 with a comprehensive policy could cost around £60.74 per month, or an annual sum of £685. This average figure is based on a specific set of assumptions about both the vehicle and the driver to provide a realistic benchmark. The vehicle is assumed to be a Group 23 model with a factory-fitted alarm system, not modified, used for social, domestic, and commuting purposes with an annual mileage of 10,000, parked in a work car park during the day and on a driveway at night. The driver profile for this average includes a 30-year-old, single teacher from London, who is a homeowner, has five years of no-claims discount, and no driving or other convictions in the last five years. It's important to remember that this is an average, and your personal circumstances will dictate your actual premium.
Understanding the nuances of insurance Group 23 extends beyond just the number. Each group can also have a letter suffix, which provides further detail about the vehicle's security features. These letters are crucial as they directly impact how an insurer perceives the risk associated with your car:
- 23E: This designation indicates that the vehicle surpasses the standard security requirements for its type, leading to a potentially lower insurance group rating. Enhanced security is always a bonus for insurers.
- 23A: Vehicles with this suffix meet the standard security requirements expected for their car type. This is the baseline level of security for the group.
- 23D: If a car is rated 23D, it falls short of the expected security requirements. This deficiency can result in a higher insurance group rating within the 23 band, as the vehicle presents a greater risk of theft.
- 23U: A 'U' signifies that the security standard of the vehicle is unacceptable. In such cases, the insurer might require significant upgrades to aftermarket security systems before they are willing to provide any coverage at all.
- 23P: This is a provisional status. It means that at the time of launch, insufficient data was available for a full classification. This rating is typically updated once Thatcham Research has had the opportunity to fully evaluate the new car's security and repair characteristics.
- 23G: This letter denotes a 'Grey import'. Thatcham Research primarily tests vehicles officially sold in the UK. For grey imports, insurers will evaluate the car based on their own pricing models and risk assessments, as standard UK data may not apply.
While selecting a car in a lower insurance group like 23 is a smart move, it's just one piece of the puzzle. Numerous other personal factors significantly influence your car insurance premium. Insurers conduct a comprehensive risk assessment, taking into account a wide array of variables:
- Engine Type and Capacity: The larger and more powerful your car's engine, the more expensive it generally is to repair or replace. Consequently, your car insurance premium will rise to cover these higher potential expenses. A powerful engine also suggests a higher risk of spirited driving, which insurers factor in.
- Driver Location: Where you live and where your car is typically parked plays a pivotal role in determining your premium. Areas with higher crime rates, particularly for car theft, or those with a greater incidence of accidents, will see higher premiums. For instance, a 30-year-old in central London might pay significantly more for a Volvo V70 than the same individual in Newcastle, purely due to the postcode risk. Urban areas, with more traffic and parked cars, naturally carry higher risks of minor collisions or vandalism.
- Driver Age: This is one of the most impactful factors. Insurers use vast amounts of claims data to determine how likely someone of your age is to make a claim. Younger, less experienced drivers, particularly those under 25, face substantially higher premiums due to their elevated risk profile. As an example, a 20-year-old driver in London could pay a considerably higher amount for an Audi A1 compared to a 40-year-old Londoner, reflecting the difference in perceived risk. Premiums generally decrease with age and experience, provided a clean driving record is maintained.
- Marital Status: Statistically, married individuals are often considered lower risk by insurers, which can sometimes lead to slightly reduced premiums. This is often attributed to married drivers being perceived as more responsible or having fewer claims.
- Car's Safety Rating, Security, and Anti-Theft Precautions: Beyond the group rating letters, specific advanced safety features (like autonomous emergency braking) and robust security systems (such as tracking devices) can further lower your premium by reducing the likelihood of accidents or theft. The more secure your vehicle, the less risk it poses.
- Likelihood of Your Specific Vehicle Being Stolen: Some car models are more attractive to thieves than others. Insurers track these trends, and if your specific vehicle type has a high theft rate, your premium will reflect that increased risk.
- Your Driving Activity: Your annual mileage is a direct indicator of your exposure to risk. Driving less can lead to lower premiums, as you spend less time on the road where accidents can occur. The type of usage (social, commuting, business) also matters; business use typically carries a higher risk.
- Your Driving History, Including No-Claims Discount (NCD): A clean driving record with no accidents or convictions, coupled with a substantial no-claims discount, is one of the most effective ways to reduce your premium. Each year you drive without making a claim, your NCD builds, offering significant savings. Conversely, past convictions or claims will increase your costs.
- Your Credit History: While not directly related to driving, some insurers use credit scores as an indicator of financial responsibility, which they may believe correlates with a lower likelihood of making fraudulent claims or defaulting on payments.
- Your Occupation: Certain professions are statistically associated with higher or lower risk. For example, some jobs might involve more driving, or parking in higher-risk areas, or simply be perceived as more or less risky by insurers based on their historical data.
While opting for a car in insurance Group 23 (or even lower) is an excellent starting point for keeping your car insurance costs down, there are several other proactive steps you can take to drive down the cost of your premiums:
- Drive Safely and Maintain a Clean Record: This is arguably the most impactful advice. Any driving convictions, such as speeding fines or points on your licence, will significantly increase your premium. Maintaining a clean driving history, free of claims and convictions, is the best way to earn and keep a substantial no-claims discount, which can lead to considerable savings over time.
- Reduce Your Annual Mileage: Insurers consider your annual mileage when calculating your premium. The less time you spend on the road, the lower your exposure to risk. If you can reduce your annual mileage, perhaps by walking, cycling, or using public transport more often, your premium is likely to drop. Be honest about your mileage, as understating it could invalidate your policy.
- Pay Annually: If your financial situation allows, paying your car insurance premium in one annual lump sum can save you money. Insurers often charge interest or additional fees if you opt to pay in monthly instalments. By paying annually, you eliminate these extra charges.
- Install Extra Safety and Security Precautions: Beyond the standard features of your Group 23 car, consider adding additional approved security devices like tracking systems, advanced immobilisers, or even a dashcam. The safer and more secure you make your car, the less risk it poses to the insurer, potentially leading to a cheaper premium. Always inform your insurer of any modifications.
- Don’t Just Accept Your Renewal Quote: Loyalty doesn't always pay in the insurance world. Your current insurer's renewal quote might not be the most competitive option available. Make it a habit to use price comparison websites every year to shop around for the best deal. You might be surprised at how much you could save by assessing your options and switching providers. Consider getting quotes from direct insurers too, as not all appear on comparison sites.
- Increase Your Voluntary Excess: While this means you pay more in the event of a claim, agreeing to a higher voluntary excess can reduce your upfront premium. Just ensure you can comfortably afford to pay this amount if you need to make a claim.
