Reinstating open fire in upstairs bedroom - regs

[Biggus thingus]

Hi,

Looking at buying an older property

The chimney has been boarded up but i've a feeling it would be easy to rip off the plasterboard/ply cover and expose an original open fire in the bedroom. Or worst case scenario, rip out and reinstall open fire and then use

can just imagine the open fire crackling away whilst laying in bed drinking coffee/reading paper with mrs thingus

Are there any regs relating to this to prevent you doing it?

Also looking at ripping out old gas fire and putting a wood burner in on ground floor. Presumably may need to line the flue or give a sweep at least?

thanks for replies

It's just investigative at the mo, and possibly more romantic than practical

Concentrating on downstairs but will update any progress
