Oh dear!

Had a conservatory built last year and installed 2x double sockets on 2 4mm2 cables as radial spurs off 2 sockets in the living room ring. The cables are run in the cavity, (3" brick outer, 3" thermal block inner with a 3" cavity and cables laying on a strip of dpc on the concrete. 1 light fitting and switch taken from the living room light, (loop-in system). Is this ok? Also no-one from building works or LAB notified. Am I in trouble?
Everything tested and up to 16th regs BTW.

No it's all wrong & illegal......
You shall be dragged from your bed in the early hours of the morning, taken to a dark & forboding building to be question harshly by some nasty blokes (or women if thats what floats your boat), for infomation on who undertook the installation work.

You will give this infomation.

Then be stood against the conservatory wall & shot.




Dont worry yourself about it
Spurs are fine in 4mm
Nothing in regs against running cables in cavity ( not my cup of tea but sometimes needs must)
Lighting extended from existing circuit is also fine
No need for LBC to have been informed it's not notifiable work.
Tested on completion, again spot on no problems.

I thought bricks, blocks and cavities were all 4" wide these days!

Thanks comms! haven't done much installation work for over 20 years and since coming on here have realised how out of touch I've become. reading about part P so often just got me a bit concerned.

Oh and by the way, there is only one woman who floats my boat!

BS3036, you may be right. All I know is that it clears the 50mm rule no problem!

Thanks guys.

i don't think there's an electrical reg about cables in building voids, but i think there's a building reg against it.....

I recall someone saying that it was a no-no unless you clipped it to the bricks..

Something about transmittion of moisture from the external skin to the internal skin

Better than the lights in my conservatory which consisted of a 1mm T&E feed connected into the back of a socket in an adjacent room in the house, through a hole in the wall to straight to a light switch and then to the lights. No RCD protection on the main board either. And house came with all certification from building control for additions. Previous owner was a keen gardner and when I viewed house was using conservatory as a greenhouse and was potting on plants there with moist soily hands!
This little scheme was apparently done by the conservatory company.
Discovered when we were going round working out which breaker switched off each socket / light.
All now removed / sorted as house now rewired.
