Hundreds of forecourts across Scotland are now charging more than £2 per litre for diesel, according to analysis by BBC Scotland. Drivers have been left shocked this week as prices jumped above the threshold, with experts warning there is "no end in sight" for the current rises.
The price hikes come as drivers across the country are impacted by ongoing conflicts in the Middle East and the Russia-Ukraine war. The RAC warned the average price of diesel in the UK could hit a record high this weekend.
Scottish islands see highest prices
The analysis, collecting data from Shetland to the Scottish Borders, suggests around 226 sites are displaying diesel prices higher than £2 per litre. Some of the highest prices can be found in the Scottish islands, with some forecourts currently 50p a litre more expensive than supermarkets in the central belt.
The highest prices are in the Hebrides, where drivers are seeing prices of 239.8p and 223p in rural areas. While hundreds of other forecourts remain under the £2 threshold, many are only a penny or two away. Hauliers have described the hikes as "devastating" for their businesses.
Prices at highest since Iran conflict
According to the latest data from RAC Fuel Watch, current prices for both petrol and diesel are the highest they have been since the outbreak of the Iran conflict at the end of February this year. Diesel is now 56.5p more expensive than at the beginning of the year, while petrol prices are on average 41.1p more expensive than they were on February 28, 2026.
Motorway services have jumped over the £2 threshold, with diesel currently sitting at 216.04p. The UK-wide average is not far behind, and the website notes these prices are still likely to rise.
RAC warns of record high
RAC head of policy Simon Williams said: "The average price of diesel is teetering on the brink of a new all-time high at 198.32p, taking the cost of a 55-litre fill-up for a family car to £109."
"The record of 199.09p will almost certainly be surpassed over the weekend as retailers continue to pass on the increases they're seeing when they buy new supply."
He also reports petrol is now at its highest price in more than four years, averaging 173.6p. The price of petrol has risen by nearly 12p in September alone after dropping slightly over the summer season.
Williams adds: "Sadly for drivers, there appears to be no end in sight to high prices at the pumps as the cost of a barrel of oil hit $106 having been around that $100 mark for the last two weeks."
"A significant drop in the price of oil is badly needed but this seems unlikely without the US and Iran striking a deal."
The UK Government stated it will continue to protect British people and businesses during this time. It also added there would not be an increase in fuel duty this year, which currently sits at a flat rate of 52.95p per litre of standard petrol and diesel.
