Hi Janet
Has been known before.
Go down near the skirting and drill 6 holes in what ever's there, keeping the holes close together so you can put a plastic air vent over them or one made out of plaster that you can stick on and paint oooooooooooooorrrrrrrrrrr
If you think it will look to unsightly go at it from the alcove at the side of the fire place; you will need a very long drill bit, if not make a hole by removing a brick and what's behind it until your in the chimney area; This needs to be about 1m up the wall.
