had a laugh at a job in fareham, where the Polish outfit had fitted a boiler to the wall and wanted it commissioning....only trouble was that the boiler was sited under a carport...the pipe which they perported was the gas supply was the rising main to the flat upstairs, and to boot they had fitted a bath shower mixer on the wall as an outlet. Other faults included no tanking in walls, tiling directly to the earth floor, undermining the exterior walls, no soundproofing or fireproofing between the buildings....etc,etc.Client had paid out 22 grand for the works, only to have the council declare the flat uninhabitable. I did manage to get her a full refund on the boiler, which was a little recompence (supplied by BandQ!)
