Plus need to figure out the AV side, largely where speaker cables are going as want to put in either ceiling speakers or high bookshelf speakers and link them to multiple sources.

And I'm also trying to figure out if the boiler can start where it is or not, which depends on whether I can go extend the flue about 3m....

Fun times, although I should hopefully get what I want and not spend years wishing I'd considered more when doing it.


One thing I'm considering with the electrics though is combining some circuits, such as kitchen lights with the bedroom lights, as it seems excessive to have whole seperate circuits for 1 or 2 lights, or a single array of downlights. Are there any rules about this?
I know it would obviously be a bad idea to have !lights and power on the same circuit (spurred off) for the same room ASA failing device would plunge you into darkness but are say light circuits on different floors OK to combine?
Its not ideal but providing the fusebox is clearly marked its not a problem, you can infact argue benefits that you'd not loose
an entire floor of lighting if you lost for example ground floor lighting due to a popped lamp etc.
Most lighting circuits are normally specific to a floor thats all, but im not aware of anything that would cause this to be
an issue (Just mark the board 'Upstairs and Kitchen lighting')

Not telling you how to suck eggs, but avoid running the AV, Data or SELV cables alongside mains cable, the installation cert will have
an inspection box for segregation of Class 1 circuits, requires a 50mm space minimum.

Also, im sure you're going to, but a top tip if not, go LED lighting (Downlights etc) bulb life and power saving etc its amazing, I have
removed all my halogen MR16's and replaced everything with WWhite LED and I've gone from 900W to 108W with the same light level !!

I do some great stuff in kitchens nowadays, LED strip lights under worktop lips, kick board lights (sometimes in blue, sometimes in white)
LED soft lighting (In green, blue) on top of the cabinets - Looks fantastic.. Undercabinet lights, been about for years but still works well.

COAX feeds for drop down screens under wall cabinets, LED Draw lights, honestly, there's lighting for everything lol

Yeah, I'll keep it all separate... Still planning the AV stuff, not sure what I'm doing as yet, possibly a Chromecast audio setup and multiple amps, with the TV outputting to one.

I think I'll do that and just mark it up if there's no rules against it. Makes more sense and as you say saved losing a while floor. Thinking of doing 5a wall switched lamp sockets upstairs too.

Likely to use these lights... http://www.toolstation.com/m/part.html?p=73671

I've put them elsewhere in the house, they come with halogens but I've fitted LEDs, they're fireproof too.

Look like good lights, nicely sprung, some come with a hopeless spring and the light never quite pulls itself flat
to the ceiling, I always try to supply the fittings but every now and then someone trying to save a dollar goes
online and finds some awfull, cheap and crummy fitting, so good choice sir :)

Hi, I'm not sure if anyone in here can help...

I'm planning on doing a load of work to my house, extensions side and rear. We'll need planning permission and building regs approval/inspections.

I'm getting the shell done and part of the inside plastered, however plan to do the electrics and plumbing myself, along with other interior stuff (stud walls, architrave flooring etc).

My question relates to the The Best Modular Wiring Company
I'll be wiring with reference to bs7671, as situated by building regs. I'm confident that I will be able to do this and conform to the rules set out (although I'm not convinced most installations do conform after reading various parts).
The planning portal website clearly states that anyone can do this, you just need it improved and inspected by the local planning authority.
However, do you need to document everything you do in order to get it signed off? Do I need to sketch what I plan to do and get it approved in advance or can they just come and inspect it after??

Doing it myself will save maybe £2k so its worth the effort, but I'm not sure how an uncertified person goes about getting it done.
Obviously registered electricians are on the competent persons scheme so just self certify.

Any ideas? Anyone done this? If I need to draw it up in advance that's fine, I just done want to wait until its all done and then find I can't get it approved due to nothing being visible.


Cheers
