Overview

• Retail fuel margins remain significantly above historic levels, costing drivers £1.6bn last year.
• Supermarkets' fuel margins have doubled since 2019, contributing to higher costs.
• Current voluntary price data-sharing covers only 40% of forecourts, limiting its effectiveness.
• A proposed 'pumpwatch' scheme could save drivers up to £4.50 per fill-up by providing real-time price data.
• The CMA calls for swift legislative action to enforce comprehensive fuel price monitoring.
