Well if it’s already in your own house, then nobody is going to force you to change it, but you can’t install a new socket without RCD protection or remove RCD protection from one that already has it.

You can’t omit RCD protection for a specific appliance any more. In fact it’s very difficult to omit for any reason these days where BS1363 sockets are concerned

Frankly, I wouldn’t care if it was mortgageable or not as I wouldn’t live there. Looks like a total disaster (like most old houses in most towns/cities). Unless you have plans to knock down and rebuild.

It still happens though

Interesting read, thanks. Wonder if you can answer me this… Not far from me there are 2 fuel stations about 100m apart, both owned by MFG. One was BP and the other Shell for many years. They both closed for a refurb about a year or so ago at the same time. When they reopened, the BP had become Shell and the Shell had become ESSO! I’m sure there must be a reason, would love to know what. Why not just swap the BP to ESSO and leave the Shell as is!

Diesels should be replaced by EV eventually. Can’t beat the sound and experience of a supercharged v8 though

The industry bodies don’t much care whether or not you’re an electrician. Only that you pay good money every year to have their little badge.

Not quite true as a large amount of installs will be fitted with BS61008 RCCB's which are all bi-directional. It's only B61009 RCBO's where the issue arises, as these are usually uni-directional unless otherwise stated. This never used to be a problem until a couple of years ago, when it suddenly became a problem. Now, it doesn't seem to be a problem anymore. It's almost like magic.

It’s a fair point if you want it to go off and stay off in the event of the smoke detector circuit going down.

Or get a normally closed contactor.

You can get TP RCBO’s yes. I’m sure I wouldn’t be introducing a N-E fault as a way to disconnect a circuit! Just run the circuit through a contactor and have the output from the aico relay module switch the coil of the contactor.

Good advice. Sounds like the architect is trying to maximise what they can get out of you. If you have the structural engineers drawings and calculations, then speak to a couple of good builders. It's likely you have all the information you need already. M&E drawings for such a small project is borderline ridiculous if you already know what you want. I'm currently working on a job worth £20k of electrical work and they have no M&E drawings whatsoever! That's the other end of the scale, a bit annoying, but the client tell me what they want/I point them in the right direction and we get it done.

Unfortunately I need it in the next few days so a bespoke item is out. Also it’s quite large so I’m not sure how I’d get it up there! Chimney measures 1400x 650mm ish

There’s a few around on period properties, but no idea where I can get one from. Google isn’t helping, which is why I thought of a wall coping. Either that or replace the corbel course with blue engineering bricks
