Insurers that do not allow drivers to mirror their no claims discount typically add 67% or more to a premium, research from price comparison site Moneysupermarket has shown.

Research from the website found that 10 of the UK’s biggest insurance groups are evenly split between those that allow drivers to use their no claims discount again when buying a second car and those that don’t. Insurers choosing to allow mirroring include Swiftcover, Virgin and Zurich. Those that do not allow mirroring include LV=, Budget and the Post Office.

According to the website, a 30-year-old female who wants to buy a Vauxhall Astra would expect to pay less than £230 for insurance if her insurer allowed her to mirror her partner’s no claims discount. However, insurers that don’t allow mirroring would typically charge between £370 and £550 for an annual premium.

Richard Mason, director of insurance at Moneysupermarket, said: “It is a little known fact that many insurers now allow you to mirror your no claims discount from one car to the next. The most common question on our forums is ‘why can’t I use my no claims discount on two cars?’ It is a good question and thankfully one that more and more insurers are starting to wake up to.

“If you are thinking of having more than one car in your household, it is prudent to choose an insurer that allows you to make the most of your no claims discount. Hopefully all insurers will soon follow suit on this.”
