What is RAC Fuel Watch?
RAC Fuel Watch is a free fuel price tracking and news service run by the RAC motoring organisation. It publishes daily national average pump prices for petrol and diesel, tracks historical trends, and provides commentary on why prices are moving. It is primarily a transparency and awareness tool — giving consumers and journalists a trusted source for UK fuel price trends — rather than a tool for finding cheap stations near you. The RAC also campaigns for fairer pump pricing based on the data it collects.
Best for: Motorists, journalists, and fleet managers who want to track national fuel price trends, understand what drives price movements, or benchmark their local prices against the national average.
What is WorthThePump?
WorthThePump is a free UK fuel saving calculator. Enter your number plate, confirm your vehicle, and WorthThePump fetches live prices from every nearby station — then tells you exactly how much you'll save (or lose) by driving to each one, after accounting for the detour fuel cost.
Best for: Drivers who want to know whether a cheaper station is genuinely worth the trip — not just the cheapest price, but the actual net saving for their specific car.

How much does RAC Fuel Watch cost?
Completely free. No sign-up required. Part of the RAC's free advice and information service.
Can RAC Fuel Watch find me the cheapest petrol station near me?
No. RAC Fuel Watch is a national price tracker and commentary service, not a local station finder. It publishes daily averages but cannot tell you which specific station near you has the cheapest fuel today.
Is RAC Fuel Watch data accurate?
RAC Fuel Watch publishes reliable national average data, often citing BEIS (now DESNZ) official statistics alongside its own monitoring. However, because it shows averages rather than live prices at individual stations, it cannot reflect real-time local pricing.
