How much would it cost

[NoRoomInBed]

How much do you think it would cost to remove the gas fire and the brick things. Even the wood stuff on the walls.

That's two jobs- gas safe plumber to cut the gas and then a labourer to take the fireplace out. You hand with a sledgehammer? I think the plumber will charge more for what is a very quick job - at least £50 to make it worth his/her while to come out. Then its another £50-100 to take the fire and bricks out and yet more if you are asking for it to be disposed of.
What are you replacing it with? It will undoubtedly need some replastering...

You could get the wood cladding off easily yourself possibly... The trouble is making good the wall afterwards, theres 50 years of who knows what behind there, at least. The walls could be absolutely terrible, and even worse once you remove the cladding.

Also, is there chimney breast in the rooms above? It'll need supporting at ceiling level if so. We removed a fire which had been capped off and opened the aperture ourselves but I wouldn't be happy taking out a chimney breast without appropriate temporary and permanent support lined up.

Was just thinking of taking all that away and having just a wall?

We're having the gas supply to our old cooker capped off at the meter next week and it's costing us £60 plus VAT.

You could probably do a lot of the removal yourself but would likely need a skip - so somewhere around the £150 - £250 depending on how much you need to get rid of.

The additional unknown would be the making good - wall would likely need plastering, you may have to replace the flooring and you may need to tidy up the sub-floor also.

Depending on how it connects at the ceiling you may need to have that plastered too

Chimney breast in the room above could add to the cost quite a bit as LBOCS2 says.

Ahh I'll not bother then. Sounds like far too much work.
