Sedgemoor Services Fuel Prices (M5)
Today's pump prices at Sedgemoor Services, and what you would pay just off the M5.
Sedgemoor Services sits on the M5 between J21 and J22, operated by Welcome Break and Roadchef in Somerset. Like almost every motorway service area in Britain, its forecourt charges a significant premium over ordinary roadside stations — commonly 15 to 20p per litre, which is £7 to £10 on a single 50-litre fill.
That premium exists because motorway forecourts have a captive audience, high site costs and a legal obligation to stay open around the clock. It is not a scandal, but it is a choice you should make knowingly rather than by default. This page shows the live Sedgemoor Services price alongside the cheapest forecourts within a short drive of the junction, so you can see the actual gap today rather than a rule of thumb.
Prices come from the UK Government's CMA Pump Watch open-data scheme, refreshed twice daily. Where Sedgemoor Services does not report to the scheme, the page shows the nearest reporting forecourts to Burnham-on-Sea, Highbridge and Weston-super-Mare instead, which is the comparison that actually changes your decision.
