fixing heights domestic

[driverman]

Hi 2nd attempt writing this! As some of know wiring new house for family member. After great discussion / debate on another thread re those damn extractor fans with timers etc. I've decided to go with wall mounted 1g light switch outside each en suite (customers request as doesn't like pull switches) and the 3 pole isolation switch at low level 450mm as opposed to high level or above the door. Will that comply with BS7671 Regs? I'm going to use a fan whereby the manufacture will not insist on a 3amp fuse.
I'd already chopped in a deep box for a shaver point in 1 en suite at face height when the penny dropped that I had in fact installed it too high. I have now installed it at no higher than 1200mm. I take it height restrictions includes shaver points also.
Now for wall mounted TV points. Many wall mounted TV points to be installed, like a damn hotel! I've installed the boxes so as no higher than 1200mm. I would like to mount them a bit higher really so as to hide the boxes behind the wall mounted TV when installed. Your thoughts,experience appreciated.

Surely before doing a job you find all the relevant regs that it needs to comply with, purchase the relevant literature too (BS7671, OSG and the Electricians guide to the building regs) as minimum?

What is people's problem with putting a fan isolator in the loft?
If an inline fan is in the loft then there should be an isolator next to it. It is the same as any other fixed equipment in this respect, an isolator should be installed locally.
Personally I fit either a rock rose or a click 'flow' type connector next to inline fans so that they can be easily removed for replacement or whatever.

MDJ thanks for reply. My concerns about TV points came about on my own house with building inspector when I did an extension. He inspected first fix before dot dab plaster board installed and was amazed to see metal capping used through out. Anyhow he pulled me up because i had installed TV skt too high. I said I would put a sw /spur point at low level to switch skt on/off. Possible building inspector was wrong to say that, but I had go with his thoughts as i didn't know otherwise. I am an electrician but been out of the game for many yrs but recently taking a keen interest in the trade again. Hence not up to date with many regs, especially building regs.
Looking at others houses though, I'vr noticed many electricians putting skts bhind Tv's but no higher than 1200mm

Okay Understand, I know some building inspectors are total Numpties, When I had my loft converted years ago when part p first came out he wanted a part p certificate and wouldn't accept an NICEIC EIC from me lol, so I get your point.

Same here mate, easy for taking away and cleaning, just unplug and remove in seconds and seconds to re-fit, it should be something all good sparks do.

just to confirm... ceiling fans with time delay being installed not in line fans installed in the loft.

if they are 12 volt you will need to put the tranny somewhere

reading at the mo..building regs, but like BE7671 you read one sentence then another which contradicts the first sentence.

YES ,basic stuff if you do it day in day out in the domestic market. i agree 100%

Part M is pretty clear on the height of switches and sockets.

I know mate...... i just look at it as a guide and use my common sense in most scenarios !!!!

Part M is pretty clear on the height of switches and sockets.

part m 4.30 a) states skts TV points heights 400 -1000mm not 1200mm

4.30 b) says perm connected 400-1200mm unless for a particular appliance. Would you class 13asocketperm connected? TV classed as an appliance?
