How the figures are computed
Each average is the mean of the prices changed in the last 7 days at the filling stations of Sunbury-on-thames, motorway services left out and prices more than 25p from the day's median discarded. The cheapest and most expensive stations are judged against the stations within 10 km, so that a typing error cannot top the list. The week runs from Monday to Sunday. Details on how this site works.
