Fuel Prices in South West
Live petrol and diesel across Bristol, Plymouth, Exeter, Bournemouth and the wider region.
Fuel prices across the South West are not uniform, and treating the region as a single number hides the thing that actually saves you money — the 10p per litre gap that can exist between two forecourts within the same postcode area.
The South West runs above the UK average the further west you go. Bristol and the M5 corridor are competitive, but Devon and Cornwall carry longer delivery distances and thinner competition, which shows up at the pump.
This hub covers the BS, PL, EX, BH, TQ and TR postcode areas. Pick your nearest city below for a ranked list of every local forecourt, or search any postcode in the region to see live petrol and diesel prices in pence per litre, sourced from the UK Government's CMA Pump Watch open-data scheme and stamped with the time each price was last confirmed.

Frequently Asked Questions
Where is fuel cheapest in South West?

Which postcode areas does this page cover?
The BS, PL, EX, BH, TQ and TR areas, plus the surrounding towns that report to the CMA scheme. Individual city pages give a tighter local ranking.
How current are these South West prices?
