" google oftec - I think they have some technical guides on their wibble


Thanks John - will have a browse around their site..

What I am not sure is the "procedure / order" to do things...

e.g. does "permission" need to first be granted (by the Council / Building
Control / other ) to put a boiler in, or do you just get it done / do it
yourself and get it commissioned / signed off by an OFTEC guy when all done
and then tell the Council / BCO / others ?

Thanks again,

Nick
