Hello guys,

I'm looking to install underfloor insulation on the ground floor of my house. I've currently got the floor up. I may have access to kingspan to do the job, if I don't I'll be looking to use loft insulation. My question is what rules should I keep to with the ring main cabling. I understand that it needs to beable to cool down so dont cover it straight over, would tacking it to the underside of the joists be acceptable?

Much appreciated
CoXen

Does it have to be split?

I was thinking of just running the whole part of ring main in 20mm conduit

I was going to use 2.5mm twin and earth, just wanted to ensure it followed the regs. So I'm assuming regarding insulation, as long as it's not covered by the insulation, it just has to follow the normal regs.

Thanks

@holmslaw

Why do you say conduit is a bad idea in domestic installations ?

I have used it as protection against rodents which T+E wouldn't give, or so I believe.

He doesn't need to drill through the joists as he has already said:

So he could attache the conduit to the underside of the joists.

PS. Memo to Cox377. Careful with Holmslaw' advice. He only has mud floors where he is from and consumes too much coconut hooch to be reliable.
