wind Noise and ventilation in chimney

xyz123

hi

we moved into our current home few months ago. original fireplace has been removed and replaced with the decorative electric bulb fire.

i am hearing a lot of noise coming from the fireplace in living room, when its quite windy outside.

the fireplace is in living room and goes through to the bedroom on first floor directly upstairs. there is a small ventilation cover in the room upstairs. see image below.

questions are:

1) what do i need to do to stop the wind noise? is it being caused by chimney not being sealed on roof?

2) if so, any idea as to how much will it cost to seal the roof (i am in NW london)

3) can i remove the ventilation cover on bedroom? as due to draft coming in , it makes room very cold. for now i have covered the cover with a cardboard which has stopped a lot of wind coming in bedroom.

4) i cant see any screws holding the ventilation cover in bedoom. any idea as to how to remove it?

We have a smaler vent in the lounge like that but purchased one where we can slide it shut. I suspect it been stuck on with something. If you are going to decorate you should be able to carefully prise it off.
