About each brand

ASDA has long positioned itself as a price-setter on UK fuel, using its forecourts as a marketing tool to advertise low-cost positioning. Historically ASDA operated a national price cap — every ASDA forecourt charging the same headline price on the same day — though recent reporting (notably by The Grocer) has documented meaningful inter-store variation on individual days. ASDA's forecourt network grew substantially in 2023 after it acquired EG Group's UK operations (356 predominantly freehold petrol stations). ASDA has been owned by the Issa brothers and TDR Capital since October 2020, with TDR Capital taking majority control in 2024.

Sainsbury's operates filling stations attached to its larger supermarket sites. Sainsbury's forecourts are generally priced in line with other big-four supermarkets but can sit a pence or two per litre above ASDA on typical days, particularly in rural areas. The main draw of Sainsbury's fuel is integration with the Nectar loyalty scheme — drivers earn 1 Nectar point per litre of fuel, with occasional multiplier promotions boosting that rate. Note that Nectar points can only be redeemed on fuel at the kiosk, not at pay-at-pump. Sainsbury's uses local competitor surveys to set prices, so sites with a Tesco or ASDA nearby track those competitors more aggressively.
