Which fuel brand is cheapest right now: the 13.6p spread
By Anthony Sharkey, Chief Operating Officer, New Reg Limited · 6 Aug 2026
Official price data ranks every major UK fuel brand: Go averages 150.8p a litre, 13.6p below the most expensive.
Go currently has the cheapest average unleaded of any major UK fuel brand at 150.8p per litre, measured across 29 of its forecourts reporting through the official price scheme. The most expensive of the 25 brands compared is Gleaner at 164.4p, a difference of 13.6p a litre or £7.48 on a 55-litre fill.
The five cheapest brands on average: Go at 150.8p across 29 sites; Maxol at 154.4p across 88 sites; Solo at 154.6p across 36 sites; Circle K at 155.9p across 42 sites; Tesco at 158.9p across 510 sites.
The average across all 25 brands compared is 160.1p per litre. Only brands with at least 20 forecourts reporting are included, so a handful of sites cannot distort the ranking, and motorway services operators are left out because their prices reflect the motorway premium rather than the brand.
Two things to keep in mind. A brand average reflects where that brand operates as much as how it prices, so a chain concentrated in one part of the UK can read cheap for regional reasons. And an individual forecourt of an expensive brand can undercut a cheap one locally, while prices move daily. Check the brand pages on this site for each brand’s live prices and its cheapest sites, or search your postcode to compare every forecourt near you.
