I’m going to be having my chimney removed to below roof level as it is in a bad state. How should I cap the top of the chimney in the loft? The fireplace below is blocked off with no vents and I do not plan on venting it.
 
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?

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.

I think building control is for removing the entire chimney stack and breast, but not for the bit above the roofline.

Why do you want to cap the remaining part in the loft?

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?

Hi ree,

It was only a suggestion he will do what ever I want him to do. He was giving me a cheaper option and a future proofing idea.
 
Unless it is a period property or the stack has some sort of decorative value which enhances the property it may be worth keeping.
Otherwise unused and in poor state I would advise removing.
If it's an internal stack it can be sealed off in the attic..a flue on an external wall should have high and low level brick vents installed.
 
OP,
How can removing a stack & repairing the remaining hole in the roof be cheaper than what might be a simple repair?
However, unless pics are seen then its a bit difficult to be more definitive about the state of the stack. Neither can we see what the roofer claims he saw.
Further, professionals typically have the flue(s) swept before any kind of work that involves chimney flues.
