UK motorway fuel premium holds at 15.2p a litre

By Anthony Sharkey, Chief Operating Officer, New Reg Limited

Official price data puts unleaded at motorway services 15.2p a litre above the branded forecourt average, with a 48.0p spread between individual sites.

The captive-audience premium at UK motorway services stands at 15.2p per litre for unleaded this week: 177.2p across 163 reporting motorway sites against 162.0p at ordinary branded forecourts.

Dispersion within the motorway estate is wide. The cheapest reporting site is Solo, 254 Frosses Road at 149.9p and the dearest Welcome Break, Hungerford at 197.9p, a 48.0p spread that exceeds the supermarket-to-branded gap seen across the wider market.

For a driver the premium is worth £8.36 on a 55-litre fill. It remains one of the most persistent structural features of UK forecourt pricing, and Promo tracks it continuously as part of its fuel market record.
