Fuel Prices in Essex
Live petrol and diesel across Chelmsford, Colchester, Basildon, Southend-on-Sea and the wider region.
Fuel prices across Essex 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.
Essex is well served by supermarket forecourts along the A12, A13 and M25, which keeps the county competitive — but the M25 service areas at the western edge charge far more than the retail parks a couple of junctions away.
This hub covers the CM, CO, SS, RM and IG 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 Essex?
Supermarket forecourts lead on price across most of Essex, particularly where two sit close together. The exact cheapest station changes daily, so use the live search rather than assuming a single winner.
Why do Essex fuel prices vary so much?
Local competition dominates. Essex is well served by supermarket forecourts along the A12, A13 and M25, which keeps the county competitive — but the M25 service areas at the western edge charge far more than the retail parks a couple of junctions away.
Which postcode areas does this page cover?
The CM, CO, SS, RM and IG areas, plus the surrounding towns that report to the CMA scheme. Individual city pages give a tighter local ranking.
How current are these Essex prices?
Data is ingested from the Government feed twice a day and each station shows its own last-updated time. Anything older than seven days is excluded from rankings.
Is diesel more expensive than petrol across Essex?
Usually, by roughly 4-8p per litre, in line with the UK-wide gap. The spread varies by station and brand, so both grades are shown side by side on every city page.
