Overview
- The CMA’s first annual monitoring report shows average pump prices fell year on year to 135p per litre for petrol and 142p for diesel between November 2024 and October 2025, reflecting lower wholesale costs.
- Retailers’ profits on fuel remain at historically high levels, which the CMA says are not justified by operating cost increases.
- Non-supermarket forecourts have driven much of the recent margin rise, while supermarket per‑litre margins have edged down from 2022 highs to about 9.6p this year.
- The CMA will require retailers to supply pricing data to the 2026 Fuel Finder and says it will take action against those that refuse, with government modelling pointing to potential savings of 1–6p per litre.
- Motoring groups report wholesale petrol costs have fallen by more than 7p per litre since late November, yet average pump prices have barely moved, describing a familiar ‘rocket and feather’ pattern.
