Had a service yesterday and my inset gas fire was condemned, i'm thinking rather than replace it i would like to switch to coal. Wouldn't use it a lot since mainly use rads but will be nice now and then. The opening is there and gas engineer did a smoke test and checked the flue visually and appears to be ok. What price roughly would you say i would be looking at? is it just a matter of having the chimney swept and tested further and then a fireback and throat lintel being installed? have taken below pics so you can see what i have.
