Exeter

The very top of the local range is set by a small number of expensive outliers, and most stations sit much closer together than the headline gap suggests. The supermarket sites, including Sainsburys, tend to set the floor for prices here.

2 of the 16 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 BP around Redlands.

Several of the busier sites sit along Trusham Road and Honiton Road, so you can check them against each other without leaving your usual route. The local average sits several pence over the wider South West England figure, which makes shopping around matter more than usual here.

Diesel averages around 188p per litre across the stations listed for Exeter. The comparison covers stations up to roughly 10 km out, which keeps out-of-town supermarkets and bypass sites in the same view as the town centre.

The cheapest station in Exeter is not fixed; the low spot moves between forecourts through the week, so the current ordering matters more than habit. The table below carries the exact live figures per station, and alerts can flag a drop at the forecourts you actually use.
