Why are some cars cheaper to insure than others?
In the UK, cars are categorised into one of 50 insurance groups with Group 1 being the lowest risk and cheapest to insure and Group 50 - the fastest and flashiest cars - the highest risk and most expensive to cover.
However, factors like age play a big role in how much you pay for car insurance. Therefore, the cheapest cars to insure for new drivers differs from what is generally cheaper for everyone.
Other factors affecting insurance costs
As well as the model of car; the driver's details and claims history, the following details are also taken into account when it comes to calculating your premiums:
Car make and model
Car modifications
Driver's occupation
Annual mileage
Driver age
Tips for cheaper car insurance
No matter your age or the insurance group of your car, there are ways to reduce your insurance costs:
Improve your security: If your car is parked off the street, such as in a garage or on a driveway, you'll likely pay less for insurance. Installing an alarm or immobiliser can also be beneficial.
Limit your claims: Paying for minor repairs out of pocket can help you maintain your no claims bonus, making you less of a risk in the eyes of insurers.
Use a black box: For younger drivers, telematics insurance can help keep costs down by monitoring driving habits. Safe driving can lead to discounts on premiums.
Pay annually: Opting to pay your insurance in one annual lump sum every year is usually cheaper than monthly instalments.
