UK price history
Daily UK average premium diesel prices in pence per litre, 19 September 2026 to 20 October 2026.
Premium diesel rose 3.1p/l, from 215.2p/l on 19 September to 218.3p/l on 20 October. Over the latest 7 days, the average fell 0.2p/l, which cuts against the wider rise. This is the national average, not a promise about every local pump, so it is still worth comparing nearby forecourts.
This chart follows the daily UK average premium diesel price in pence per litre, from 19 September 2026 to 20 October 2026. It shows the direction of the national market rather than the price at any single forecourt, so use it to judge timing and the rankings below to judge where.
Each point is a true daily average of prices published by UK forecourts under the government Fuel Finder scheme. Days appear only once their prices are confirmed, gaps are never filled with estimates, and every movement figure on this page is calculated from recorded prices.

What premium diesel adds and how to decide whether it is worth it.
Premium diesel is standard B7 diesel with an enhanced additive package: detergents to keep injectors clean and, in some blends, a higher cetane rating for smoother combustion. Each retailer markets its own formula, which is why prices vary so widely between brands and forecourts.
Whether it is worth the extra cost is debated. Standard diesel already meets strict quality requirements, and the clearest benefit is for high-mileage engines or those that have run on cheaper fuel for a long time. If you do use it, the rankings above show where it costs least.
Treat the national average as your benchmark, not a promise: premium diesel pricing is the least consistent of any fuel, so checking the town pages and individual forecourts before you fill up goes furthest here.
