Frome

At the bottom of the local market, unleaded starts around 155p per litre right now. Right now roughly 7p per litre separates the cheapest unleaded from the dearest locally.

The supermarket sites, including Asda and Sainsburys, tend to set the floor for prices here. 2 of the 6 local forecourts are supermarket-run, and the rest split between branded and independent operators.

The low end of the market has recently been held by Asda around Warminster Road. Several of the busier sites sit along Warminster Road and Trowbridge Road, so you can check them against each other without leaving your usual route.

Local unleaded prices average slightly above the wider South West England figure. For diesel, expect an average of roughly 175p per litre locally.

The comparison covers stations up to roughly 8 km out, which keeps out-of-town supermarkets and bypass sites in the same view as the town centre. The cheapest station in Frome is not fixed; the low spot moves between forecourts through the week, so the current ordering matters more than habit.
