Due to poor condition I have decided to have our chimney stacks removed from the roof upwards. We have gas heating with approved boiler flue and no wood burners. Does anyone know of any regs that would not allow the removal.

No rules that I know of.

There are a couple of cheaper options than rebuilding with bricks, a) concrete preformed units or b) stainless steel double lined prefab chimney, in the event you want a cheaper alternative to retaining one of them.

However I would urge you to take them down to the ceiling level and then to cover the remanent with insulation, and not just to roof level. If the chimneys are only taken down to roof level you will finish up with a big heat sink sucking heat out of your house.

There is an argument for removing stacks completely to get back the space they consume and remove unsightly lumps in the walls, if thats an issue for you. In the uk, people often do this, leaving the stacks above in place for aesthetic reasons - but that pile of bricks needs specislist support..

A simpler alternative is removing the front of the stack, leaving 2 support pillars and revealing an instant bookcase or similar.

If your new flue runs up an older chimney - safety demands they are above roof height or the wrong wind can fill your roof/house with noxious gasses, but im guessing its a flue in the wall...
