OK to run lighting wiring behind coving?

I did the kitchen ring main in my old house exactly like that and it worked a treat. As for the compliance with the standards, I defer to those more qualified than me. Cannot see why it should be a problem. Steve

I don't see any problem with the regs. I've done this a lot with ethernet and other low voltage cable. A room with coving all the way round effectively has tunking all the way around. You can easily drill through it for access and then polyfilla the hole when you're done. An expanding tape measure or springy drain cleaner make an excellent draw wire.

Coving falls within the permitted 150mm area from the top of the ceiling - the NICEIC website has a pictoral PDF illustration.

MK do a range of coving specifically to aid cable routing, in both 44mm & 90mm (IIRC). Internal/External, adapters, drops. So as a point of reference it is a well supported approach.

Only note re routing is keep cables 25mm from gas pipes, keep sockets/switches 150mm from gas pipes - if you go digging.

Conventional channel/trunking (plastic or it would need to be earthed) & coving would probably be cheaper than MK. It lacks a truly seemless design - EGA Cornice, p332 MK catalog #46.

I doubt cable grouping or temperature are an issue re lights.

Watch light position for when you are seated in the lounge, eg use of widescreen laptops re angled reflective displays. (Like people fitting 50W halogen in bedrooms over a bed only to realise the problem when they then lay in the bed :-)

Thanks for this and other replies - extremely helpful!
