Yes. The RAC motoring group said on October 2, 2026, that the average UK diesel price had risen to 200.01 pence a litre, the first time it has topped £2, while the average petrol price reached 174.71 pence.
RAC policy head Simon Williams called £2 a price threshold no one wanted to cross. The group said filling an average family car with diesel now costs £110, almost £32 more than at the start of the US-Iran war. It linked the surge to months of disruption from that war, tighter global diesel supplies after Ukrainian attacks on Russian refiners, and Chinese limits on refined-fuel exports.
