Hi ree,OP,
Removing a chimney stack from above the roof takes away character from your property - stacks are also sometimes a bit of a selling point for a home not just a box for living in.
Given your previous complaints about excessive humidity in the house then sealing the flue at both bottom & top might not be a great idea in terms of ventilation?
I think building control is for removing the entire chimney stack and breast, but not for the bit above the roofline.Hi ree,
We have a piv fitted now and some lap vents air flow seems to be good in the loft now. But we have a leak coming down the side the chimney. My roofers advice was to remove the stack rather than repairs to avoid any issues in the future. But after speaking to building control today the seem to think I need to put an application in although google searches tell me different.

Why do you want to cap the remaining part in the loft?
Hi ree,OP,
Because you have a leak, possibly from the stack, showing on the chimney breast in the loft you now wish, on the advice of a "roofer", to disfigure the appearance of your house?
How come the "roofer" couldn't fix the leak on the stack?
There are a couple of points that may need your further attention no matter what happens with the stack - so why not post pics of the stack, and the leak in the loft?
