What drivers in Somerset should know

The gap between the cheapest and most expensive forecourt in Somerset is currently 9.0p per litre. On a typical 55-litre fill that is about £4.95 — worth a short detour if a cheaper site is already on your route.

At 175.4p the average unleaded petrol (e10) price in Somerset is above the UK-wide average of 174.7p that PumpScan is tracking, a difference of 0.7p per litre.

Brands represented locally include CENTRAL CONVENIENCE, TEXACO. Supermarket forecourts usually undercut motorway services by a wide margin, and prices in and around Somerset tend to move within a day or two of a change in the wholesale oil price. Filling up mid-week and avoiding a near-empty tank on a motorway trip are the two simplest ways to keep costs down.

Compare Somerset against the rest of the country on the cheapest petrol in the UK and cheapest diesel in the UK leaderboards.
