Frequently asked questions
How often are fuel prices updated?
Every forecourt reporting to the Fuel Finder scheme must report price changes within 30 minutes, so prices shown here reflect that near-real-time reporting rather than a daily or weekly snapshot.
Is this official data?
Yes. All prices come from HM Government's Fuel Finder open data scheme, which every fuel retailer in the UK is required to report to. We don't edit or estimate prices — they're shown as published.

Enter your postcode and choose a fuel type in the search box above. The nearest matching stations are shown closest-first, with a map, using your postcode's location — no account or app download needed.
How many petrol stations are tracked in Gwynedd?
100 forecourts in Gwynedd report to Fuel Finder.
What if a price looks wrong?
Please report it directly to Fuel Finder using the link in the footer — we display their data as published and can't edit individual station prices ourselves.
