RAC reports UK average diesel price at 198.32p a litre
Published · Updated
What happened
RAC published fuel-price data showing average UK diesel prices at 198.32 pence a litre on 25 September 2026. UK media reported that retailers were expected to raise pump prices further as higher wholesale and refining costs feed through.
Why it matters
Diesel is a direct input cost for haulage, logistics, construction and many small businesses, so a rise of this size can feed into consumer prices within days or weeks. It also sharpens scrutiny of fuel retail pricing and complicates the inflation outlook for monetary policy and wage-setting.
RAC data reported on 25 September 2026 put the UK average diesel price at 198.32 pence a litre, close to the 2022 peak. The update ties higher pump prices to recent moves in wholesale fuel markets and refining disruption, with retailers expected to pass through more cost increases. For ministers and regulators, this is an immediate transmission channel from external oil-market disruption into household budgets, freight costs and near-term inflation expectations.
