Hounslow

At the bottom of the local market, unleaded starts around 148p per litre right now. A few outlying forecourts price well above the typical local level, so the average is a better guide here than the extremes.

The supermarket sites, including Tesco and Sainsburys, tend to set the floor for prices here. 10 of the 64 local forecourts are supermarket-run, and the rest split between branded and independent operators.

Asda has been setting the cheapest unleaded price locally of late. Forecourts on Millington Road and Hampton Court Way carry much of the passing trade, and their prices often move first.

Average unleaded here tracks the wider Greater London figure closely. Diesel averages around 166p per litre across the stations we track in Hounslow.

Everything within about 8 km of the centre is included, so edge-of-town and retail park sites appear alongside the central forecourts. Prices in Hounslow can move mid-week as well as at weekends, so the ordering above is worth a glance even if you always use the same forecourt.
