The weekly change compares the same 78 filling stations with an unleaded price on both days, so a station dropping out of the figures does not move it.
105 of the 156 stations seen during the week changed at least one price.
The cheapest unleaded in London on Sunday 4 October 2026 was 162.9p at Stc Service Station, London (E15 1LN); the most expensive was 184.9p at Belsize Station Limited, London (NW3 4QE), a gap of 22.0p, or £11.00 on a 50-litre tank.
The cheapest diesel was 185.9p at Greenman Service Station, London (E11 1PP).
Across the UK, unleaded was up 0.7p over the same week, at 174.7p, which puts London 0.1p above the national average.
"Drivers in London paid 0.8p more for a litre of unleaded this week. On a 50-litre tank, that is £0.40 more than a week earlier. The gap between the cheapest and the dearest forecourt in London is 22.0p, so where you fill up still matters more than when." said Jacky A., editor of fuelpricetoday.co.uk.

How the figures are computed
Each average is the mean of the prices changed in the last 7 days at the filling stations of London, motorway services left out and prices more than 25p from the day's median discarded. The cheapest and most expensive stations are judged against the stations within 10 km, so that a typing error cannot top the list. The week runs from Monday to Sunday. Details on how this site works.
