Overview

• Despite wholesale costs easing, petrol and diesel prices have risen to 138.2p and 141.9p per litre respectively due to a two-week transmission lag in retail adjustments.
• Motorway service stations are charging surcharges of 20p–30p per litre, costing drivers up to £15 more per tank and pushing some pump prices above 170p per litre.
• Seven motorway service stations—Tiverton, Cullompton, Lancaster, Oval, Magor, Cardiff West and Ferrymuir—are offering fuel up to 10p per litre below the motorway average.
• Major A-road routes such as the A1 and A55 average about 140p per litre for petrol and 147p for diesel, delivering savings of roughly 16p per litre compared to motorway prices.
• Pump price transparency through the CMA’s voluntary scheme and apps like the AA App are helping drivers locate cheaper forecourts along holiday routes.
