Men in their twenties pay 41% more for their motor insurance than those in their thirties, according to research by Moneysupermarket.

The analysis of 12 million motor insurance quotes by the price comparison site for the past year reveals the average car insurance premium for a man in his twenties was £370 – £108 dearer than the £262 average for a man in his thirties.

Women enjoyed cheaper premiums until they hit their fifties. The average quote for a twenty-something woman was £320 over the past year – 16% cheaper than their male counterparts.

Overall, men paid 9% more for their car insurance cover compared with women. But the starkest difference was for teenagers, with 18-year-old women paying £861 less than males. Teenaged males who get through their first year of driving unscathed enjoyed a reduction in premiums from £1,815 to £874 when they hit 19.

Peter Gerrard, head of insurance research at Moneysupermarket, said: “Young and newly qualified drivers have long been perceived as high risk by the insurance industry and often find it hard to get competitive motor insurance. But there are ways they can cut their insurance costs, such as adding a parent to their policy or looking at specialist insurers who target young drivers.

“It’s also clear that insurers view women as far more mature motorists at an earlier age.”

The findings also highlighted older drivers getting better value for money for their car insurance compared with younger ones. Female drivers in their fifties were paying £203 per year on average compared with £320 for a female driver in her twenties. Similarly a male driver in his fifties was paying £199 compared to £370 for those in their twenties.

Gerrard added: “Older drivers generally find their cars cheaper to insure so this can make it tough for specialist insurers to offer better value for elderly drivers. Motorists who are prepared to shop around for the best deal each year will always come out on top, whatever their sex or age.”
