The UK average petrol price was 173.2p a litre in the week beginning 26 October 2026, down 0.7p on the week before, and diesel averaged 198.5p, down 0.2p, across 8,036 reporting petrol stations.
What oil is doing
Brent crude averaged $119.81 a barrel over the week, down $1.21 on the week before. Crude is the largest component of the pre-tax pump price, and oil moves typically take two to four weeks to reach petrol stations, so the barrel sets the direction of travel more than any single week's pump price. The full history is on our fuel price trends page.
What it means for a tank
At this week's averages, a 55-litre fill of a typical family car cost about £95.26 with petrol (£0.37 less than a week earlier) and £109.19 with diesel (£0.10 less than a week earlier).
Where fuel was cheapest
The cheapest region for petrol was Greater Belfast at 165.3p a litre, and the cheapest for diesel was Greater Belfast at 189.6p. The full regional table, with every nation and region, is in this week's UK fuel price index edition.
The shop-around gap
The national average is only half the story: within most towns the spread between the cheapest and dearest petrol station is wider than a typical week's whole national move. Comparing prices near you usually saves more than waiting for the trend.
