I do hope this hasn't been done to death, but here goes.
Constructing new bathroom shower room. I understand I have to fit a fan to the exterior. Also the missus wants an illuminated wall mirror (low voltage). Can I feed both of these from the bathroom lighting circuit and do they have to have fused accessible connections outside of the bathroom. Also fitting an Aqualiser shower unit. Can this be fed from a spur from the ring main on that floor. Thanks everyone.
just get on with it ffs, why do you need BCO and Part P?
blow yourself up and then there is one less dumbfuck to worry about or put hand in pocket and pay a man a proper fee for him to kill himself and take resposibility if you die too!
that's what 'tricians are for. they dont call them sparkey's for nowt!
Would you like to take responsibility if one of your family died because you screwed it up? Quite apart from the safety implications when the OP comes to sell the house if he cannot produce the paperwork he will not be able to sell the house until he gets the work check and authorised so much better to do it now. It my be a PITA but it is a fact of today's nanny state.
No - the fan may require a fuse, but the this can be in the bathroom as long as the fused connecton unit is in zone three or outside the zones. You also typically want an isolator to completely surn off the fan for maintenance. If your fan is the type activated by the bathroom light then this needs to be a three pole device.
If this is a "power shower" (i.e. a thing that simply pumps water to increase pressure) then yes. If it actually heats the water (i.e. much higher power consumprion) then no, it will need a dedicated circuit.
I've lost count of how many times I've fixed pro sparks work in friends houses. The worst work I've ever seen was on a house bought new from Barret. Second worse was on a kitchen fitted by one of the large companies. Every single terminal screw was loose, and some had melted the insulation. It also included woodscrews being used to pick up the fixings in the boxes beneath the tiles as the originals weren't long enough. And several where they'd run out of earth sleeving.
Whilst the rules are a pain in the backside they are there for a reason. Not only that you may save yourself money in the short term by not following them it will cost you long term. If that is carping then I plead guilty!
On an aside, and not aimed at this thread in any particular detail, personally, I find the hysteria associated with domestic electrics rather tiresome. Driving is a far more dangerous activity, yet everyone does it. That's not to mean that people shouldn't aspire to do the safest job, but there is certainly plenty of hysteria around.
Yes - there are utter incompetents who install broken dangerous crap - but I suspect they are less likely to be here asking about it. Being here and asking indicates a degree of caution and responsibility.
It's fair to warn about the existence of Part P (the OP can ignore, but at least in knowledge), it's fair to perhaps ask the poster if he still feels upto the job (but with civility) - he may have been done perfectly reasonable wiring before, but is aware that regs have changed and may merely be questioning whether his knowledge is out of date.
What I would recommend to sploop is to get a copy of this:

read it cover to cover. It's not that big a tome and it is a practical interpretation of the IEE Wiring Regs. Has lots of pictures of standard configurations and down to earth simple interpretation.
A lot of common questions are answered - and, more importantly, IMO, you get a good overview of recommended practise and thus you find yourself in a better position to know what you don't know - at least it does that for me.

Indeed. It is entirely possible for someone without a piece of paper and an annual payment to an organisation set up for these two purposes to do a proper job on domestic wiring. All it takes is the right knowledge and experience. Unfortunately the administrators are taking over. They are not interested in whether something is done well or badly, but only in whether some paperwork is done properly.
One can say much the same thing about gas. By now, if one believes the proponents, the CORGI process should have saved thousands of lives. However, when asked for the figures the proponents become very coy. Meanwhile "the experts" still manage to blow people up.

I agree.
I agree. However, asking basic questions can also indicate that someone should do some basic research on their own before asking further. Libraries have useful books that can be an aid to study.
The Electrician's Guide to the 16th Edition of the IEE Wiring Regulations, BS7671 and Part P of the Building Regulations by J.F. Whitfield is precisely the right book to get out of the library and study.
