If you are an expert on Building Regulations please read on.
My neighbour has built a block of 3 flats right up to our joint boundary, i.e., on the boundary, and has included two vents in the boundary wall, which discharge foul air onto my property. I believe that the vents, which are open, 100 mm diameter, without grilles, are from cooker hoods. Do building regs allow this ? What are the consequences for me if I were to build right up to the boundary and block the vents ?
The flats have gas fired central heating, each vented to a flue on a non boundary wall. There is no further ventilation. When a CORGI plumber fitted my central heating he insisted on an additional vent through the wall in the room containing the boiler. Mine was not a balanced flue, the flues in the flats might well be.
Is auxillary venting to the atmosphere of a gas fired appliance required under building regs ?
