Wall cavity insulation
Then block off the *chimney*, just above the fireplace, and leave the
fireplace as a feature. Because you will no longer be able to use the
fire, you can also block the vent.
Indeed. That is what I was proposing, although I didn't mention the chimney.
The back room ones already have the chimney sliced off anyway, due to the
loft conversion coveting the space.
