The MG 5’s running costs really hammer home the benefit of electric cars, and MG throws in a few sweeteners of its own in the form of one of the longest warranties in the industry, generous service intervals and comprehensive service packages. Whether buying privately or for business, running costs should be low, thanks to zero CO2 emissions – although you may find insurance a little more pricey than for a combustion-engined estate.

MG 5 SW insurance group

The MG 5 falls into group 27 for insurance. With no direct equivalent in the market, it’s difficult to draw direct comparison, but an electric SUV like the Kia e-Niro spans bands 20-29 depending on trim level, so the MG 5 is perhaps a touch highly rated compared to some cars that cost a little more to buy.


Short of Kia's policy, the MG 5’s seven-year/80,000-mile warranty is the longest in the industry, and a huge reassurance for anyone concerned about the longevity of electric cars. Kia’s warranty goes 20,000 miles further over those seven years, but 80,000 miles really isn’t to be sniffed at, particularly as it fully covers the battery pack, too.


We’ve got used to seeing some fairly broad service intervals on electric cars, and the MG 5 is little different. While MG still recommends the car comes in for a checkup each year, you can do up to 15,000 miles in that year – a benefit of not requiring oil and filter changes like a combustion-engined model. MG also offers service plans for the 5, priced from as little as £6 per month over two to five years. 12 months' AA roadside assistance is also included.

Road tax

With zero tailpipe CO2 emissions, the MG 5 neatly falls into the bottom road-tax band and so won’t cost a penny in VED when first registered – or any year thereafter, for that matter. It’ll cost very little for business users to run either, as Benefit-in-Kind is just 2% right now, which effectively means spending less on a year’s BiK than most people will spend on two or three tanks of petrol for a conventional car.
