I own a leasehold flat on the top floor of a small block. The leaseholder is building another layer of flats on top of the building, directly above my flat.
The flue from my gas boiler currently vents through the roof that they're building on. They say that building regs mean that the flue can't be extended to go through the new layer of flats, so they want to re-route the flue of my boiler through my bedroom to vent to an outside wall instead of up through the new flat/roof. This would mean an ugly boxed in flue through my bedroom and remodelling of my built-in cupboards to accommodate it.
Do I have any way to stop them doing this? They are saying they're going to cut of my gas if they can't do the work because they're removing the flue. I feel this is unfair as it was their choice to build the new layer of flats.
I think another option is for them to replace my gas boiler with an electric boiler so there is no flue. This would cost them more, obviously. Am I entitled to ask/insist on this option?
