newcomers said:The job is well out of my area and its highly unlikely ill be doing work for the client again (its a favour for a mate whos doing work for an agent)
Could it be that your "mate" already knows that this boiler is not straightforward and thats why he does not want to do it himself?
Another thing, doing a questionable job outside your normal area increases the chance of having to make a return visit.
I am always hesitant about doing jobs for Agents, only today I had a call from one who clearly seemed to have questionable intentions about paying.
