I have been contacted by a potential customer who has bought a reposessed property that has been empty for some time but which has a band b boiler fitted but not comissioned. Its plumbed in but not wired and the gas pipework has not been fitted. If I commission it will it constitute a new install? It wouldnt pass as permitted under diferent circumstances as a band a could be sited in same location without issue. Should it just be ripped out? The boiler is a potterton performa combi.
