Actually on31 i wasn't seeing how many gullible plumbers what reply i'm in the process of setting up a canvassing company for replacing old boilers with new A grade boilers so was trying to get hold of a booklet for my guys to hold onto so they could flick through and find if the boilers they come across can be replaced or not.
Thanks to everyone else for the links to various websites that have the list, they will help me a lot !
Oh dear.
