How to read the regional benchmark and move from an area-wide average to a useful local comparison.
The premium diesel average for the South West combines current qualifying prices from reporting forecourts across the region. It is a benchmark for the area, not a promise that every town or forecourt will charge the same amount.
Town prices vary with local competition, retailer mix, delivery costs and how many forecourts serve the area. Use the cheapest-town preview to see regional leaders, then open a town page to compare individual forecourts before making a journey.
The directory follows canonical source-enriched localities in the South West. Membership is not based on a hard radius, and specialist directories include towns with current qualifying evidence for that fuel, including useful sparse pages that remain outside the sitemap.
