While new electric car prices have been rapidly increasing in recent months, the MG4 has launched with a starting price of just under £26,000, making it one of the very cheapest electric cars on sale today. And even if you want to upgrade to the Long Range model, that’ll only set you back less than £28,500, which is several thousand pounds less than you’d have to pay for the equivalent VW ID.3 or Cupra Born.

Of course, like all electric cars, you pay zero road tax for the time being, company-car tax is much lower than any petrol or hybrid alternative and even servicing should be relatively inexpensive as well. Simply put, the MG4 will be one of cheapest-to-run family cars you can buy – electric or otherwise.

MG4 EV insurance group

We don’t know yet what insurance groups the MG4 will fall into, but we expect it’ll attract similar ratings to rivals like the VW ID.3 (18-26), Cupra Born (25-28) and Nissan Leaf (21-28). 


MG’s impressive seven-year/80,000-mile warranty for its electric cars is among the best in the business,  providing coverage for the car and its batteries. Those offered by Kia, Hyundai or Toyota do have longer coverage periods and mileage limits, we don’t expect many people who get an MG4 on a three or even four-year finance deal will come close to exceeding that 80,000 limit. But it undoubtedly provides peace of mind.


MG offers service plans on its electric cars from as little as £6 per month, with repayments spread over two to five years. The service plans cover periodic maintenance, safety inspections and 12 months' AA roadside assistance. Although, exact service intervals have yet to be confirmed, either.

Road tax

As with all zero-emissions cars, the MG4 doesn't attract any road tax. That may change in the near future as the number of electric cars on the road goes up, but for now it's one less bill to worry about. Electric cars also avoid the London Congestion Charge and enjoy only 2% Benefit-in-Kind (BiK) company-car tax for the next few years.
