Upminster

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.

6 of the 36 local forecourts are supermarket-run, and the rest split between branded and independent operators. Tesco around Cygnet View has been setting the cheapest unleaded price locally of late.

Several of the busier sites sit along Hornchurch Road and A127, so you can check them against each other without leaving your usual route. Unleaded prices around Upminster sit broadly in line with the rest of Greater London.

For diesel, expect an average of roughly 176p per litre locally. 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 Upminster 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. Use the live table for the exact prices at each site, or set an alert if you would rather be told when your usual stations drop.
