Quick summary: The UK battery electric vehicle market reached a record 27.3% market share in May 2026, driven by motorists seeking zero tailpipe emissions, lower maintenance costs, and various government purchase and installation grants. Despite these immediate environmental and financial benefits, prospective buyers must navigate higher insurance premiums, uneven regional charging infrastructure, and future policy changes such as the upcoming pay-per-mile road tax. For public policy and public health, addressing these infrastructure gaps and financial barriers is essential to accelerate the transition towards green transport, which dramatically improves urban air quality and supports community well-being.
Electric vehicles are gaining popularity among UK drivers, with the battery-electric vehicle market share reaching 27.3% in May 2026. This marks the strongest May performance for EVs since 2019. As fuel prices remain volatile, many motorists are weighing the switch to EVs to take advantage of zero tailpipe emissions, improved air quality, lower running costs, and government incentives. Car insurance experts at MoneySuperMarket have shared key insights into the advantages and potential drawbacks of owning an electric vehicle.
The benefits of EV ownership
One of the biggest advantages of owning an electric vehicle is the potential for lower running costs and reduced maintenance, since EVs have fewer moving parts than petrol or diesel cars.
Drivers can also access substantial government support
- The Electric Car Grant offers discounts of up to £3,750 on eligible new zero-emission vehicles.
- The Chargepoint Grant for Renters and Flat Owners covers up to 75% of the cost of installing a home charging point, up to a maximum of £500.
Beyond financial savings, research consistently shows that EVs produce fewer greenhouse gas emissions and air pollutants over their lifetime. Their near-silent electric motors eliminate tailpipe emissions and reduce noise pollution, contributing to quieter streets and healthier communities. This creates a smooth, relaxing driving experience with rapid acceleration, automatic transmissions as standard, and regenerative braking technology to recover energy when slowing down.
Prospective buyers must also weigh certain challenges, including higher upfront purchase costs compared to traditional vehicles, even after government grants are applied.
Furthermore, driving range and charging accessibility remain vital factors
- Range limits: While many modern battery-electric vehicles are capable of more than 300 miles on a single charge, older EV models have a shorter range that might not suit high-mileage drivers.
- Regional public charging gaps: Although more than 120,000 public chargers are available across the UK, access remains uneven. London and the South East benefit from far greater coverage than many parts of the North, Midlands and rural areas, where ultra-rapid chargers can be harder to find.
- Cost volatility: Public charging costs vary significantly depending on the provider, location and speed.
Alicia Hempsted, an insurance expert, reminds drivers to take advantage of off-peak charging to save money. “Some charge point operators have off-peak hours, offering reduced-cost charging. It may not seem like a huge difference in cost between peak and off-peak prices, but these small costs can add up.”
“Rapid off-peak charging, for example, is 19 pence cheaper than peak, which can save you nearly £10 when charging a 50kWh battery.”
“Even at home, you can benefit from reduced off-peak prices with the right electric vehicle energy tariff.”
“Peak hours are between 8 to 11am and 4 to 10pm, so consider stopping off at a charge point during your lunchbreak to save a bit of money on your next charge.””
Essential questions for prospective buyers
Kara Gammell, Car Insurance Expert at MoneySuperMarket, addresses some of the most common questions prospective EV owners have regarding taxes, rules and costs.
What is electric vehicle excise duty (eVED)?
“Electric Vehicle Excise Duty (eVED) is a new pay-per-mile tax for electric vehicle drivers, which will take effect in April 2028. It means that all electric car and Plug-in Hybrid Electric Vehicle (PHEV) drivers will have to pay an additional charge based on the amount of miles they drive each year, as well as Vehicle Excise Duty (VED) or road tax. When launched, the charge will be 3p per mile for battery-electric cars, and for plug-in hybrid cars, it will be 1.5p per mile.”
Are electric vehicles exempt from the congestion charge?
“No, electric cars are no longer exempt from the London Congestion Charge. You do get a 25% discount if you register on Auto Pay, but this reduces to a 12.5% discount from 4th March 2030.”
How much will I pay to insure an electric car?
“The average annual price of electric car insurance in 2026 is £556, according to MoneySuperMarket data. This is more expensive than diesel (£519) and petrol (£490). However, as electric cars become more widespread and easier and cheaper to repair, and as insurers gather more data, costs should fall.”
How can I choose the right electric car?
“The electric vehicle market is burgeoning with options, from compact city cars to spacious SUVs. But with so many choices, how do you find the one that’s right for you? To help you find your perfect EV, we have a handy Electric Vehicle Tool where you can compare electric vehicles based on features like efficiency and charging speed, price, and car insurance quotes.”
As the EV transition accelerates, understanding these costs, savings and practical considerations remains essential for UK drivers evaluating the switch.
