Current 13-week analysis
Quote the movement with the assumptions attached.
Every figure below is recalculated from the same checked rows as the chart and downloads.
UK average petrol fell by 0.71p/L to 174.57p/L and diesel fell by 0.71p/L to 199.33p/L in the week commencing 19 October 2026. At 45 MPG, that weekly movement would make an illustrative 100-mile journey about £0.07 less using petrol and about £0.07 less using diesel. Source: DESNZ; analysis: UtilHub UK.
Journey method: (100 miles ÷ 45 MPG) × 4.54609 litres per imperial gallon × weekly price change ÷ 100. The result is an illustration using national averages, not a local quote or forecast.
