How these figures work

A forecourt counts in the South East by its postcode area, less the districts in Greater London.

Postcode areas: BN, CT, GU, ME, MK, OX, PO, RG, RH, SL, SO, TN, HP, KT, SM, CR, BR, DA, HA, UB, TW.

The outer London districts in KT, SM, CR, BR, DA, HA, UB, TW count in London, such as Croydon, Bromley, Kingston and Harrow.

Each average uses every forecourt's latest price for the fuel while it is under 30 days old.

A price far from the UK median is counted but left out of the average, and a figure needs at least 5 prices.

Supermarkets and major brands are the groups on our brands page, each brand's own forecourts only. Motorway services are left out of both.

Each forecourt counts once in a county: the county of the nearest town we have a page for, within 20 miles. A county is listed under the region holding most of its forecourts.

Town figures are worked out each night over each town page's radius.

A town in a London borough is listed in London. Any other town is listed by its postcode and county.

Prices more than 3 days old still count, and we say so when most of a figure rests on them.

Every figure here comes from our price data, which explains where the prices come from.
