Hi after advice my customer is looking to cap off main gas supply remove boiler from wall, pipe work and all radiators taken away as he is switching to electric radiators powered by his current solar panels. I'm not gas Safe but can carry out all the draning down of system remove rads etc. Question is am I legally allowed to remove the boiler off the wall and all pipe work leading to boiler if we get a gas Safe to cap the mains first so all pipe and boiler will be dead? As it's a good customer of mine he wants me to do as much of work as possible but if I'm not allowed to touch boiler once dead then I have to pass it to gas safe engineer Thanks for advice
