Petrol Prices Discount Code Black Friday 2026 - 30% OFF

Petrol Prices is a UK website and mobile app for comparing fuel costs. Drivers use it to track down cheaper petrol and diesel near where they are or along a route they intend to drive. Prices come from a wide range of forecourts, among them supermarket sites, independent stations and the major fuel brands, so the picture it gives spans much of the market. The service syncs with the UK's fuel price transparency scheme, which keeps its local price information dependable and current.

Prices appear on a map and in a list, and stations can be sorted by whichever criteria a driver cares about. A journey planner pinpoints economical places to refuel partway through a trip. Fuel prices differ from one forecourt to the next, sometimes sharply within a single town, so comparing ahead of a fill-up is a simple way to trim what a driver spends.

Both the website and the mobile app are free to use, and the service covers the country. Tools of this sort suit drivers who want a quick read on the forecourt landscape before committing to a station, whether for a daily commute or a longer journey.

Codes go into the discount code box at the Petrol Prices checkout; deals need no code.
