The average UK price for a litre of petrol has fallen below 150p for the first time since the outbreak of war in Ukraine. The AA said that a litre of petrol typically cost 149.74p on Monday, its lowest since Russia invaded Ukraine on 24 February 2022, when it averaged 149.67p a litre. The outbreak of war in Europe sent commodity markets soaring, pushing up the wholesale prices of oil and gas. Petrol reached a record of 191.53p a litre on 3 July as surging fuel prices fed into rampant inflation and a squeeze on the cost of living. Luke Bosdet, the AA’s spokesperson on pump prices, said: “A 41.8p-a-litre crash in the average pump price of petrol is a huge relief for drivers, cutting £22.99 from the cost of filling the typical car tank.” Diesel now averages 172.21p a litre, down from a record of 199.07p at the start of July, the motoring group said. Some retailers sold diesel at over £2 a litre. However, the relief for drivers could be short lived as road fuel is set to increase by 6p including VAT in March when a year-long fuel duty cut comes to an end. The Competition and Markets Authority (CMA) was asked by the UK government to study pump prices last summer after accusations that a cut to fuel duty was not being passed on to consumers. The CMA raised concerns over the margins made by oil refineries, and then later said there was evidence of “rocket and feather” behaviour – when prices shoot up rapidly but come down slowly – in the retail industry. Its investigation continues. Last week the RAC accused petrol station owners of not passing on falling wholesale costs to drivers. Bosdet said that fuel at 150p a litre was still far higher than the previous record high of 142.48p, set in April 2012. He said: “Indicative of the chaos of UK pump pricing and the rampant exploitation of drivers by many fuel retailers, the AA spotted supermarket and non-supermarket retailers yesterday charging less than 140p a litre in south Wales and Northern Ireland. “How fuel stations in areas of big populations and high volume sales can charge well over 10p more for fuel than in largely rural parts of the UK is a question that the Competition and Markets Authority will have to address.”
