Forecourts must report every price change to the government's Fuel Finder scheme within 30 minutes. This page is rebuilt from the daily data and then checks the live feed when you open it, so the figures you see are the latest reported. Prices are per litre. A blank means the forecourt does not sell that fuel or has not reported a price.
