Cost of demolishing an external wall

[WomanWithAltitude]

We are moving into a house that had an extension done 20+ years ago. The old external wall between the original house and the extension is now an internal wall with a door in it.

We'd really like to remove this wall and open up the space after we move in. (But otherwise not make any changes to the extension). It's obviously a load bearing wall though, so I assume it will be a big job?

Obviously we'll get advice from an engineer etc, but has anyone else done this? What sort of cost might we be looking at to do it? Any pitfalls we should be aware of?

(We're up north btw, that will probably affect the cost compared to e.g. London.)

Oh, and the stretch of wall we'd like to remove is approximately 4m long, and has a gas flue in it.

We had an external, originally load bearing wall removed and it cost around £1500 including structural engineer calculations and steels. Where's the gas appliance the flue serves? I think that moving that might be a bigger issue. If the flue is higher up the same wall and won't be affected by removing the wall lower down then it's not an issue.

it's surprisingly easy to do with an angle grinder and RSJ or similar, it's making good afterwards that takes the time.

I meant an originally external load bearing wall!

The gas appliance would be being removed rather than moved. It's a gas fire.

Wow -- £1,500 is cheaper than I thought that sort of thing might be!

Okay so you've got the costs of disconnecting and capping the gas supply too. I don't imagine it will be much more. The structural engineer cost around £300-400 - I can't remember exactly.

That sounds promising. We will also need to factor in flooring etc., but it sounds like the work might be affordable.
