If you are fitting something that requires both electric and water connections, what's the right way to get trades in if you have separate electricians and plumbers?
Actually same for an electric shower... most plumbers don't have part P do they?

Presumably if you engage a heating engineer they would be covered for both?

I think that plumbers are generally regarded (rightly or wrongly) as being able to connect things to an existing nearby electricity supply - be it a water heater, immersion, boiler, CH pump or whatever - but I doubt that you'd find many electricians doing any 'plumbing' :)

This is potentially different, since installing a new electric shower (hence a new circuit) in a bathroom would be (electrically) 'notifiable' work, and therefore would usually need a 'registered' ('self-certifying') electrician involved. However, replacing an existing shower, with an existing electricity supply, would probably not be notifiable.

You cannot 'have Part P'; it is a Building Regulation with which everyone must comply.

That's it. There is no more.

As for the self-notification schemes (stupidly called self-certification schemes), they were introduced specifically for ancillary trades like plumbers.
However, in England most of the notifiable work has been removed from the list meaning most ancillary trades no longer need to join.

As said though, one remaining thing is the installation of a new circuit, so a plumber might become registered but it would hardly be worth it.

Ok so what is the certification electricians have that means they can certify their work and be held liable for it, that they all call "part p" but clearly inaccurately so? I.e work they sign off will be accepted by building control?

In my case we're talking all new. I have an electrician lined up but I'm not sure who should connect these units or in what order... Should he wire them and then someone else connects them to the water, strictly speaking?

Some units are mains plug not hard wired, does this make any difference in the slightest?

Anyone can and should certify - fill out a certificate - their electrical work. Hence why I called it a stupid name.

As you are talking about an on-demand water heater (not an electric shower), it will likely just be connected to a socket circuit, or indeed just plugged into a socket, so not a new circuit, therefore anyone can do it.

Yes, it will just be plugged in - like a kettle - so not really anything to do with the electrical side of things.
 
Obviously, you might not have a socket in the right place, so you could get an electrician to fit one first - or do it yourself.
 
So I can wire my entire house without any training, verify it and nobody will check, or care that I've no professional training?

I thought professionals had to do a lot and keep current... Or is that perhaps more to do with insurance?

Thanks for clarifying about plug-in units, that potentially makes it far simpler. I guess I figured an installed appliance might be treated differently if it is permanently plumbed.

Not really. You would legally have to notify the work to the Building Control and pay a hefty fee before you start and they may not deem you competent.

It's no different to building an extension.

No. Just a few things (in England, a lot more in Wales) have to be 'notified' to Building Control - and that essentially comes down to replacing a CU and installing new circuits (which are fundamental parts of "wiring an entire house") and certain things in bathrooms - and (quite apart from charging a few hundred pounds) BC would generally not accept that being done by someone with no training/competence.
