The United Kingdom's Electric Car Grant (ECG) program, designed to incentivize the purchase of new electric vehicles, is marking its first year in operation. Launched in July 2025, the £2 billion scheme offers buyers between £1,500 and £3,750 off eligible new EVs costing less than £37,000, with a planned duration until March 2030. However, its success in boosting electric vehicle (EV) adoption is a subject of ongoing discussion.
Government statistics indicate that the grant has assisted over 140,000 drivers in saving money on EV purchases, and EV registrations have seen a year-on-year increase of 34 percent, according to the Society of Motor Manufacturers and Traders (SMMT). Despite these figures, research suggests a significant portion of potential buyers remain unaware of the scheme. A survey by Carwow found that nearly two-thirds of car buyers did not know the grant existed, and interest in purchasing an EV post-grant saw only a five percent increase among surveyed drivers.
Awareness and Affordability Challenges
Carwow's research indicates that consumer interest in EVs hovered around 33 percent before the grant's introduction and rose to 38 percent in the year following its launch. This level of interest mirrors figures from 2019, falling short of a 2022 peak. A key factor cited for this lack of significant movement is low public awareness of the available incentives. Data from August 2025 showed only 36 percent of shoppers had heard of the ECG, with this figure rising to just 37 percent by January 2026.
Another hurdle is the upfront cost of EVs. The ECG has two tiers: Band 1 cars, considered the most environmentally friendly, receive the full £3,750 grant, while Band 2 vehicles receive £1,500. However, only 12 out of 60 eligible models qualify for the higher Band 1 discount, meaning most drivers receive less than half the maximum advertised saving. Among those aware of the scheme, only 18 percent reported that the grant genuinely reduced the cost barrier to purchasing an EV. A significant majority, seven in ten, stated they would be more likely to choose an EV if all eligible models received the full £3,750 discount.
Siobhan Doyle, consumer editor at Carwow, noted that the headline figure of "up to £3,750" is misleading for many, as the majority of qualifying cars receive the lower payment. She also pointed out that the automatic application of the discount by dealers, combined with limited promotion, has made the scheme less visible to consumers.
Narrowing Price Gap and Rising EV Popularity
Despite awareness challenges, data from Autotrader suggests the ECG has contributed to narrowing the price difference between new electric and petrol cars. The average price gap has reportedly shrunk from £1,935 to just £40 in the year since the grant's introduction. For two months in early 2026, new EVs were, on average, less expensive than new petrol cars.
Eight of the top 10 most-viewed new EVs on Autotrader in June and year-to-date either qualify for the ECG or offer a manufacturer-funded equivalent. The Renault 5 E-Tech, which can be discounted by £1,500 or £3,750 depending on the version, was the most in-demand EV during March and April.
Ian Plummer, commercial director at Autotrader, stated that the grant has helped close one of the last significant psychological barriers for drivers considering an EV. He also cautioned that the introduction of pay-per-mile charging could negatively impact EV demand, given the cost-sensitive nature of consumer behavior in this sector.
External Factors Influencing EV Uptake
Beyond the grant, soaring fuel prices have also played a significant role in driving interest towards EVs. High petrol and diesel prices, influenced by global events, have prompted consumers to seek alternatives. The AA reported a 28.1 percent increase in electricity usage for vehicles in the first quarter of 2026, as drivers increasingly switch to grid power over volatile forecourt prices. Aviation, Maritime and Decarbonisation Minister Keir Mather highlighted the potential running cost savings of up to £1,400 on EVs as a further incentive, especially against the backdrop of global fuel price fluctuations.
