Should be fine...


Fireplace on the ground floor had an old gas fire which we have
now removed and have blocked off this one as well - plasterers
are in there as I write.

ISTR seeing vents installed in some blocked off fireplaces, and
I am wondering if there is a need to fit a vent into the
fireplace.

Quite possibly not - if you decide to put one in, put an airbrick
on the outside.
