Diesel cost an average of 199.0p a litre across the 488 forecourts in London that were reporting diesel prices to the government’s Fuel Finder scheme on 9 November 2026, 1.9p above the UK average of 197.1p.
The cheapest diesel open to all drivers in London was 189.7p at Asda Beckton Superstore, E6 5JP. The dearest was 221.9p at Welcome Break London Gateway, NW7 3HU, a motorway service area. For a business buying fuel, that 32.2p difference is worth £322 on every 1,000 litres, or £17.71 on a 55 litre tank. Away from motorway services, the dearest was 209.9p at Belsize Station Limited (BP), NW3 4QE, 20.2p more than the cheapest.
Like for like, diesel prices at the 214 of those forecourts that reported on both 2 November and 9 November fell by an average of 1.1p a litre over the week. Among them, 11 raised their price, 125 cut it and the rest did not change.
Unleaded petrol (E10) averaged 169.5p across 490 forecourts, 0.8p above the UK average of 168.7p. It ranged from 159.9p at Greenman Service Station (Jet) to 196.9p at Welcome Break London Gateway.
Supermarket forecourts were the cheaper place to fill up with diesel: they averaged 196.0p across 79 sites, against 199.6p at the other 409.
For fleets, 358 of the 488 forecourts selling diesel told Fuel Finder they sell fuel 24 hours a day, and 21 have AdBlue at the pump. None of them listed HVO renewable diesel.
How the figures were worked out
The figures come from Fuel Finder, the government scheme under which every UK forecourt must report its prices within 30 minutes of a change, published as open data under the Open Government Licence. British Fuel Prices records the feed several times a day. Averages cover the forecourts on its London page that reported a price in the 14 days to 9 November 2026; older prices are left out. London here means the London region, by postcode. The figures include 3 motorway service areas. Weekly changes compare the same forecourts’ prices at both dates. Prices are pump prices in pence per litre, including duty and VAT.
