Electric Cars Set to Surpass Diesel Vehicles in UK by 2030

Electric Cars Set to Outnumber Diesels by 2030 in Great Britain

Electric vehicles are on track to surpass diesel-powered cars in Great Britain by the end of the decade, with London likely being the first UK city to eliminate diesels entirely.

According to a report by New AutoMotive, there were 9.9 million diesel cars on British roads in June last year, marking a significant decrease from their peak of 12.4 million. The shift to electric vehicles continues, though not as swiftly as automakers anticipated. For more insights, visit this link.

While electric cars are gaining traction, the transition for vans lags behind, with diesel van numbers climbing to a record 4.4 million.

The early 2000s saw a surge in diesel vehicles due to favorable tax policies, as diesel engines offered greater efficiency and lower carbon emissions than petrol engines. However, they also produce more harmful nitrous oxides. The 2015 Volkswagen emissions scandal, known as “Dieselgate”, revealed that the company manipulated emissions tests, resulting in significant financial repercussions and health impacts, as shown in studies.

Sales of diesel cars have since plummeted, with fewer than 100,000 sold in the first 11 months of 2025. Despite this, many diesel vehicles purchased during their peak years remain in use.

Data from the Society of Motor Manufacturers and Traders (SMMT) indicates that battery electric cars constituted only 4% of vehicles on UK roads last year, compared to 32% diesel and 58% petrol. Hybrids made up the remaining 6%.

As older diesel vehicles are phased out, urban areas could see improved air quality, and fuel stations may reduce diesel supply. London, due to its ultra-low emission zone (Ulez), is expected to lead the way in going diesel-free. Diesel vehicles are also decreasing rapidly in Scotland’s central belt, home to Edinburgh and Glasgow, both of which have low-emission zones.

Ben Nelmes, CEO of New AutoMotive, emphasizes the need to “end the use of diesel” to improve air quality in British cities. He states, “The UK is now rolling out electric cars at a rapid pace, and this is great news for everyone that enjoys clean air, quieter streets, and really cheap running costs.”

Despite the decline in diesel cars, rural areas may see an influx of used diesel vehicles from urban centers. The analysis also suggests that while diesel van numbers have increased, their peak was likely before the pandemic, implying future declines.

Matt Finch, co-author of the report and environmental policy expert, remarks that the “diesel age” is ending. He acknowledges diesel’s past utility but asserts, “No one is denying diesel hasn’t been useful, but it has had its day.”
