LPG autogas is by far the most widely available environmentally friendly alternative fuel with over 1400 refueling sites throughout the UK, most of which are on petrol forecourts.
Making it the third fuel in the UK.
Convert your car or van to run on LPG autogas - you can find full information on this website or for a summary leaflet click here 
Make sure that you choose a UKLPG Approved Autogas Installer to ensure you benefit from the UKLPG Quality Assurance Programme and Consumer Code. Only UKLPG Approved Installers can operate the UKLPG Vehicle Register - look out for the logo opposite and to find your nearest installer use the search facility at the top of this page.
A conversion by a non approved installer may be taken to any UKLPG Approved Autogas Installer to be checked and if satisfactory added to the UKLPG Vehicle Register. However rather than have a non approved conversion followed by a vehicle check for which remedial work may be necessary and costly, we would recommend having the conversion done by a UKLPG approved converter and get the assurance that UKLPG is behind you.
