Prices are published by the retailers themselves under the government's fuel price transparency scheme and are shown in pence per litre. A forecourt only appears here once it has actually reported, and we show its reported date rather than assuming today's price. Prices can change between a retailer reporting and you arriving, so always check the pump.
