More than 300 fuel stations across the country are now charging over £2 a litre for diesel, including several in Devon. An extra 33 forecourts raised their prices overnight, taking the total to 326 garages in the UK that have breached the £2 threshold for standard diesel in the last week. At five of those, standard unleaded, usually cheaper than diesel, now costs 199.9p a litre.
At £2 a litre, filling a standard family car costs £110, at least £30 more than the average price at the start of 2026. Prices shot up after the US and Israel launched attacks on Iran on February 28, and there has been another spike since the start of September as the continuing conflict puts further pressure on oil prices.
A third of the stations charging £2 a litre are motorway services, but many suburban and rural forecourts also charge that much. In Devon, they include a Murco at Rockbeare, a BP at Tiverton, Highfield Garage at Honiton, and others as shown on the map below. Just over the border, an Esso garage at the A38 Carkeel Roundabout near Saltash has also topped the £2 mark.

The prices are based on data supplied by retailers and updated daily as part of the government's Fuel Finder service, set up to help motorists get a better deal from fuel companies. The average price of diesel across all UK forecourts is now 195.3p a litre, with standard unleaded at 172p a litre. Both are at their highest levels since the spike at the end of 2022 caused by Russia's invasion of Ukraine.
The cheapest place in Devon to fill up with petrol is at a Jet garage in Newton Abbot. According to the latest data supplied by retailers, a driver in an average family car could save up to £20 by filling up there compared with the most expensive petrol station. The Jet garage at Aller Vale Garage, Newton Abbot charges 159.9p per litre, meaning it would cost £88 to fill an average 55-litre tank. This is based on a feed of live petrol prices published by the government.
