Hello,

I bought a new build and noticed the upstairs MCB is controlling some sockets on the opposite floor, so if I flick the upstairs MCB it's also switching off a socket downstairs (I think it's a spur) in addition to all the ones upstairs

Is there anything within 7671 that states this is wrong?

I asked the contactor on site and they said it can be re-wired but it's down to my prefrence. Is this correct? Surely the regs have something to say on this.

P.S this same contractor didn't earth some of the metal faceplate light switches (including backbox) - so I don't trust them at all. Despite having a NIC form filled in and signed by two qualifed electricans!!

Nothing wrong with having sockets on different floors wired on the same MCB as long as the labelling on the CU reflects this or doesn't mention 'upstairs' or 'downstairs' at all.
I've almost always grouped socket circuits in downstairs rooms with the rooms directly above, except for kitchens and utility rooms.

Hi nope it has stickers for upstairs and downstairs
 
It is an odd thing to do but nothing wrong with it, might gave been done if the other circuit failed you still have one close by working. Metal switch front plates not being earthed is a big issue.
 
They should both be earthed. I wonder if the other properties are the same, this sort of thing is fundamental.
I always fit a fly lead on both switches and sockets, but the last time I looked it was apparently considered acceptable to earth the plate and rely on the fixing screws to earth the box, provided one of the fixings in the box is 'fixed' and not the adjustable (to level the fitting) type.
 
They are. I asked one why it wasn't earthed correctly and he said it was an "oversight". It's fixed now (I basically told them to go around with a tester and touch each light switch for earth) but as a homeowner why am I picking these things up? Hence my concerns now with the MCBs on the consumer unit.

Yeap agreed! I told them this. All I got was a shrug and a claim they'd fix them.

They also tried to claim I shouldn't be taking faceplates off walls. However I deem myself competent and therefore within the regs. He was a bit stunned when I quoted that. Think he was more upset he was caught doing rubbish work.
 
You need to speak to the site manager not the electrical contractors. I suspect he/she may also shrug because it is being rectified but ask for their name subject to a complaint to the main contractor.
Already tried that. I said they need sacking. His response was if they sacked everyone who did a rubbish job he'd have no one to build houses! That site manager quit a week later. The new one just avoids me now. I've apprantly got a reputation on site!
 
What’s wrong with a homeowner taking a faceplate off if you isolate the circuit?


Do you have the option of a snagging list period?

New build developments are notorious for corner cutting…. In all trades.
I’m still coming across issues with my electrics after 14 years.

Tell them you’re going to organise an EICR from your own choice of electrician to find any more issues if they don’t sort it all pronto.


The threat of contacting BBC Rogue Traders can also work wonders.

Exactly my point to them. They clearly just don't like being questioned on the regs by a DIYer like me.

Yes it was on the snag list. Been here 8 weeks now. Problem is they repair it but what about the other houses who don't spot these things? I bet professional snaggers don't take faceplates off.

The EICR is a waste of time from what I've seen here
 
It's scandalous.... but such standards seem to be the norm these days.
It's also scandalous a house owner be fobbed off, by the contractor, as a trouble maker for reporting such an important matter. Report to main contractors and make it public.
EIC for a new installation, for what it's worth.

Thanks!

What good is a EIC if an electrican gets his mate to sign it? Would anything come of reporting them to NICEIC?
