You'll need to connect it up to the water as well.Hello,
I just installed an electric shower, the wiring was allready in place (done by an electrician) so i just connected the L/N/E. nothing more.
What are your thoughts?

Is it RCD protected?
edit - Yes I'd get a certificate (not really sure on this though still on my first year)
Yes everything is as it should be (i have the Part P defined scope B & C but not joined a scheme).
I allways understood it that i could replace like for like and there is no problem. Surly this is the same apart from not removing a shower?
Bit of a grey area to which i cant find the answer to online!
and ring the NICEIC if it doesn't answer your queryIts all totally academic and pointless - who in hell is going to know if you changed the shower, or for that matter a plug, socket or spur.....no one, so no you dont need a certificate. If you are competant enough to do it then you dont need to pay for someone to pat you on the back, just get on with it.

Imagine if the shower eletrocuted someone or caused a fire, during the investigation they find a 12 month old shower unit, they would be asking for paperwork i'm sure of it![]()
Its his own home, if he kills himself who are they gonna prosecute....no one, if it kills a visitor who is to say he wired it it, no one!
Its absolute tripe, wiring isnt rocket science and unless its a major rewire or somthing then there is no reason why a competant person shouldnt do it themselves.
Would you risk being uninsured for a house fire on something which is likely worth well over 100k for the sake of a £50 certificate? I'm sure they would use it as an excuse if that was the cause.
Do you call in an electrician to change a light bulb, just in case you do it wrong and cause a fire? It's easy to see why electricians make such good money with these attitudes.
If you aren't capable of connecting red/black/green or brown/blue/green wires to the appropriately labelled terminals then I fully agree you have no business holding a screwdriver. If you have have some semblance of practical skill and common sense, then safely connecting a new appliance to existing wiring is hardly a taxing job.
