One of the many concerns some Britons have about switching to electric cars is the cost of insuring them.According to the Electric Car Scheme, EVs are typically between 15 and 25 per cent more expensive in premiums than conventional petrol models.However, the latest report shows the cost of cover is falling, with MoneySuperMarket's latest Electric Car Insurance Index stating that the average EV policy now stands at £561 - compared to £587 in October 2025.That said, there is still a massive £500 gap between the cheapest and most expensive models to insure, according to the report.Fortunately, one of the EVs with the lowest average annual premiums is also one of the most popular on sale in Britain.Here are six of the most expensive models to insure - and six that will save you hundreds of pounds a year.We reveal the six most expensive EVs to insure - and there are three Tesla models on the list.

Scroll down for the six cheapest EVs to insureThe suggestion that premiums are falling is the latest in a streak of good news for the EV sector.It comes as industry figures revealed that new EVs have been cheaper to buy, on average, than petrol cars for the last three months.In March, Auto Trader said electric vehicles had reached a momentous tipping point, becoming the less expensive option.This is when factoring in manufacturer discounts, retailer contributions and government incentives.In April and May, this trend continued.The average price of a brand-new EV this month stands at £43,049 after discounts.This undercuts the average new petrol car (£43,178) and, with around 40 electric models now priced under £30,000, is 'lowering the barrier to entry for buyers', the online marketplace said.Rising fuel costs are further accelerating this shift, with Auto Trader's data showing that improving EV affordability is translating into increased demand.So, which electric models - new and second-hand - offer the most appealing premiums?MOST EXPENSIVE 1.

So, while some EV drivers now pay less than they would have done a few months ago, others are paying more.'Alongside that, our data shows that EV insurance premiums are continuing to fall year on year, meaning running costs remain a moving target.'With so many variables, drivers need to consider the full picture before committing. Comparing insurance quotes remains one of the easiest ways to manage EV running costs.'
