The weekly change compares the same 6,541 filling stations with an unleaded price on both days, so a station dropping out of the figures does not move it.

7,230 of the 8,053 stations seen during the week changed at least one price.

The cheapest unleaded in the UK on Sunday 20 September 2026 was 154.9p at Solo 24 Hr (BT80 8DR); the most expensive was 230.0p at Thorn House Filling Station, Penrith (CA10 1BL), a gap of 75.1p, or £37.55 on a 50-litre tank.

The cheapest diesel was 107.9p at Parc Service Station, Corwen (LL21 9HH).

Among the towns of the UK, unleaded fell most in Ashby-de-la-zouch (down 2.5p to 170.9p), Ossett (down 1.7p to 172.6p), Baldock (down 1.3p to 171.6p) and rose most in Shipley (up 10.3p to 180.2p), Woodbridge (up 5.6p to 173.4p), Batley (up 5.5p to 172.4p).

"Drivers in the UK paid 2.3p more for a litre of unleaded this week. On a 50-litre tank, that is £1.15 more than a week earlier. The gap between the cheapest and the dearest forecourt in the UK is 75.1p, 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 the UK, 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.
