Hello. I have a question. When I had my flat refurbished, I had my kitchen ceiling lowered to add insulation. the boiler was not lowered, so now the main box of the boiler reaches a couple of cm above the plasterboard (see photo). We can get the door off ok for inspections, but a plumber has told us that because he does not have easy access to the pipes/valves etc on top of the boiler, he cannot carry out a full service (in particular the flue gas analyser checks, I think). He says the only option is to lower the boiler at a cost of around £800. Can anyone confirm this? I can expand the cavity around the top of the boiler to make it extend around 12cm or so from the from of the boiler. Does that help? All advice appreciated. Thanks
