Quick way to get a shaving socket into the bathroom

[amjl2000]

If by cavity you mean a cavity between two skins of breeze/brick as opposed to stud work, that's a big no, no I'm afraid

It's a cavity under the sloped ceiling (because it's too low to be practical). Behind the plasterboard is insulation board (dunno the real name) and the framework to hold up the roof, and then lots of air down to the eaves.
(I'd avoid the wood framework!)

Don't forget your bathroom floor will have some interesting things in it, like water pipes.
They don't like drills up 'em, Mr Mainwaring!

make sure you pick a point where you actually have live and neutral a single light in a garage may only have switched live and neutral at the light fitting

If you was to run a cable from where you want the shaver socket to either the consumer unit position OR a point on a lighting circuit where there is a permanent live and a neutral (not all black or blue wires are neutrals) then an electrician can connect it up, and sign it off if you insist.

No - he may may not sign it off.

I'm assuming you are not Welsh however - the rules are far more restrictive there, as they are running with an older version of the building act and an older part P

Part P is the same in Wales as in England.

Well so far so good... drilled a nice big hole in the garage ceiling below, and can see right up into the cavity (had some fluffy insulation to poke out of the way first) and to where i need the cable to go. Tomorrow daylight I'll be investigating the garage lights - one switch is a pull cord right by the CU.. hoping it'll do the job (yes, I have a DVM), and I can get some 2.5mm T+E into it else It'll be a separate junction box.

Why do you want 2.5 T&E on a lighting circuit ? 1.0 T&E should be OK

Because I have 20 odd metres of 2.5 to use up! It's a pain to use where's it's not necessary, so might go buy something more suitable...

It doesn't go off, and will be waiting for you to use when you actually need that size.

 

[amjl2000]

I put the 2.5mm in my lovely shed, and bought some 1mm.

It's all wired and in place, just waiting for some filler to dry from cracking the plaster making the socket hole.
The only suspect thing I did in the garage, was....
I took the live from the light switch (L&E), and the neutral from the light fitting (N&E). The distance isn't far, and the cables are attached to the ceiling (i.e. all visible until they're trunked), and I labelled by the junction boxes I used to attach everything. All the earths are connected, successfully checked for 240V on the box that has the resulting permanent L&N (without the lights on!).
I guess there could be potential loop issues? Without tearing down the garage ceiling (which is overlapped two-thick plasterboard) I wouldn't get to where the live and neutral split.

That is rather sketchy.

Do you not have a permanent live at the fitting or a neutral at the switch? That in itself is a bit rough, means you've almost certainly got a JB buried under a (presumably) tiled floor and above two sheets of plasterboard. Hope it doesn't fail.

Did you run 2 lots of twin and earth cable to the 2 positions? What about the earths?

He said all the earths got connected, though I'm not sure about any other unused wires, which I would fit connector blocks onto the ends.

Garage ceilings are a fire barrier, the very last thing needed there is a big hole.
