Ten cheapest cars to insure in UK for 2025.. including surprisingly plush saloon & sporty convertible

A GROUP of car insurance experts have revealed the cheapest cars to insure in the UK in 2025 – with some surprising models included.

A new report from Go.Compare Car Insurance shows that it’s not just small, low-powered models that help you save on vehicle cover.

The comparison site recently shared with Sun Motors their latest car insurance price index, revealing that the average cost of car insurance is £450.

Typically, smaller, less powerful cars with good safety credentials are the cheapest to insure, such as the ever-popular Peugeot 206 and the compact Smart ForTwo.

Unsurprisingly, both feature on Go.Compare’s list.

However, there are a few unexpected entries, including the iconic Mazda MX-5 – which takes the top spot, costing an average of £250 to insure.

Long dubbed “the poster child for convertible cars”, the MX-5 has often been recognised as a mechanically reliable choice that’s also great fun to drive.

The long-forgotten Saab 9-3, praised as a comfortable and practical saloon that also boasts good looks and an excellent safety record, also makes the list.

Saab’s former Swedish rivals Volvo are also on the list with the S40, costing just £290 to insure on average.

Speaking to Sun Motors, Tom Banks, a car insurance expert at Go.Compare, explained that the model of the car is just one of many factors insurers consider.

He said: “When an insurer offers you a quote for your car insurance, they take into account a whole range of factors – your age, the area you live in, and where your car is parked can all affect the price, as well as the type of car you drive.

“Generally speaking, more powerful, sporty cars with larger engines are more expensive to insure, while cars with smaller engines are typically more affordable to insure and run.

“While it’s unlikely to be cost-effective to change your car solely to lower your insurance premium, if you’re in the market for a new car anyway, it’s definitely worth researching how much different models cost to insure.

“And if you’re not planning to buy a new car but your premiums have increased, there are certain steps you can take to try to reduce the cost of insuring your vehicle.”
