Petrol prices in the UK: up 3.5p this week to 169.3p

Between Monday 7 September 2026 and Sunday 13 September 2026, the average price of unleaded across 7,126 filling stations in the UK rose 3.5p to 169.3p a litre, while diesel rose 3.9p to 191.3p.

The weekly change compares the same 6,545 filling stations with an unleaded price on both days, so a station dropping out of the figures does not move it.

7,279 of the 8,042 stations seen during the week changed at least one price.

The cheapest unleaded in the UK on Sunday 13 September 2026 was 149.9p at Corner Filling Station, Cookstown (BT80 0HF); the most expensive was 205.2p at Steisean Connaidh Chrosabol, Crossapol (PA77 6UP), a gap of 55.3p, or £27.65 on a 50-litre tank.

The cheapest diesel was 170.9p at Go Ballymena, Ballymena (BT42 4GA).

Among the towns of the UK, unleaded fell most in Dumfries (down 0.7p to 168.9p), Ilminster (down 0.3p to 170.9p), Barking (down 0.2p to 164.5p) and rose most in Stornoway (up 9.7p to 179.6p), Larne (up 9.3p to 168.0p), Holywood (up 8.0p to 165.2p).

"Drivers in the UK paid 3.5p more for a litre of unleaded this week. On a 50-litre tank, that is £1.75 more than a week earlier. The gap between the cheapest and the dearest forecourt in the UK is 55.3p, so where you fill up still matters more than when." said Jacky A., editor of fuelpricetoday.co.uk.
