Thought you'd like an update on this mornings events.
I met the guy at his house & was immediately bombarded with verbal abuse. My brother came with me as a second pair of eyes & ears.
(I'm glad I had the foresight in this instance to record the whole conversation for future reference.)
He walked us round the house saying that each radiator was in the wrong place, undersized etc, despite him agreeing before hand where he wanted them & even marking on the wall to instruct me further. He complained that some pipework (underfloor) was unnecessary & was lashed in. He remarked at one piece in particular that he seemed to think would be damaged by carpet grippers, despite the fact that the pipe was set in to the joist below below the floorboard & as far as I'm aware the tacks used are not 3" long.
He wouldn't let us have our say & was very aggressive, despite the fact his wife was present. (Not much of a gentleman either with his language)I don't know whether he felt intimidated by the two of us hence his aggression or he was looking for a reaction.
We tried to reason with him & offer a resolution but he just wasn't interested. He even called the police which I was happy with as I said that they could mediate & perhaps we would then be able to solve the whole problem. When he phoned the police he said that we were being aggressive towards him & demanding money & using threatening behaviour. (I'm glad I recorded it all to prove otherwise).
The outcome of it all is that the police are not interested in the issue particularly (I tried to tell him this would be the case) & have advised me to telephone him tomorrow to sort out a resolution. I advised the police that he was using the boiler illegally & at his own risk as I had arranged for an independent GSR installer to certificate later today in the homeowners presence so that he could see that it had all been done properly. The police informed him of this.
So, just a waiting game till tomorrow to see what the outcome of the telephone conversation will be. If it doesn't go well I can see me having to take it to small claims court.
