The price of diesel has soared to nearly £2.50 a litre at a petrol station in Chelsea, west London. It comes three days after the cost of filling an average family car with petrol rose to £100 for the first time.
BBC Radio London went to a Gulf petrol station on Sloane Avenue where prices hit 238.9p a litre for unleaded petrol and 249.9p for a litre of diesel.
RAC motoring group’s Simon Williams said it was thought to be one of the highest in the UK.
“Every day seems to be a new record,” Mr Williams added.
“Those are particularly high prices; the average is currently 183p a litre for petrol and nearly 189p a litre for diesel.
So those prices are particularly high, some of the highest in the country.”
Gulf has been approached for a comment.
As countries turn away from using supplies from Russia – the world’s third-biggest supplier of oil – prices are rising and hitting the pockets of consumers, while government attempts to control the problems appear to be making little impact.
