Petrol falls to 172.78p a litre as pump prices drop for a third week
Diesel slipped to 198.58p in the latest government survey, but a tank of either fuel still costs more than £20 extra compared with this time last year.
Drivers paid an average of 172.78p for a litre of petrol on Monday 2 November, down 1.29p in a week, according to the Department for Energy Security and Net Zero's weekly survey of UK forecourts.
Diesel came down by 0.64p to 198.58p. Both fuels have now fallen three weeks running since 12 October, when diesel hit 200.04p and petrol 175.28p.
For petrol, this is the cheapest weekly average since 21 September. Diesel is at its lowest since 28 September.
A year earlier, on 3 November 2025, the averages were 134.38p for petrol and 142.61p for diesel. On those figures a 55-litre tank of petrol now costs about £95.03, against £73.91 then, and the same tank of diesel about £109.22, against £78.44.
That leaves a petrol fill-up about £21.12 dearer than last November and a diesel one about £30.78 dearer.
Petrol fell about twice as far as diesel this week, so the gap between them widened slightly to 25.80p a litre.
Fuel duty has been 52.95p a litre on both fuels all year, with VAT at 20% charged on top.
The department's figure is a UK-wide average. What drivers pay at any one forecourt can be noticeably higher or lower.
