Chimney breast opening floor

[Trevor Towle]

History

I used to have a gas fire on the wall with the flue going up into the attic then a tin flue to the roof. We removed the gas fire, capped the gas off, removed the tin flue in the attic and capped the flue in the attic and put an electric fire on the wall for decoration more then anything.

Possible issue.
We now want remove the fire and put wall panelling up but i will have to patch up the hole in the chimney breast. Having a look at the bottom of the hole and it looks like you can see the foundations and a very cold draft coming in. What would be the best way to fill this, could some expanding foam be put in or will dpc and conrete, not bothered how it looks as you wont be able to see it just want the draft stopping as we have laminate in the room and gets cold quick (now i know why).

Thanks.

I'd buy a roll of loft insulation and stuff it down there to stop drafts.
Then patch the hole

Abit of cement in the holes then loft insulation? Not sure about damp though.
