Costco Wholesale operates UK petrol stations exclusively at its warehouse club locations, with pumps accessible only to Costco Members (Individual or Trade). Costco fuel is consistently among the cheapest in each local area — typically several pence per litre below other supermarket forecourts (Tesco, Asda, Morrisons, Sainsbury’s) and substantially below branded retailers like Shell and BP. Petrol stations open only during Costco warehouse trading hours, and pump prices are not advertised publicly outside the warehouse — the live prices on PetrolFinder are sourced from the UK Government Fuel Finder API and updated every 5 minutes.

All prices shown on PetrolFinder are sourced from official UK government data published under the CMA fuel price transparency initiative. Data is refreshed every 5 minutes to ensure you always see the most up-to-date Costco fuel prices available.
