Adding a loft spur to a ring main

[Jimmy3]

I want to add a spur, to feed a double plug socket in the loft, to an existing ring main.
I have measured the floor area (including stairs) of what the circuit already feeds. This equates to 90M².
The IEE regs say that a ring main cannot serve a floor area greater than 100M². Would this contravene the regs as the loft is probably 28M² but isn't strictly a floor as it isn't habitable?

You'll be fine. You are (after all) only adding a spur to the existing ring.

I often wonder what other type(s) of sockets there might be....

Actually, they don't.

If the loft is habitable space i.e. likely to be heated, then treat as a new room and supply a circuit accordingly.

If all you want to plug in is a handlamp and power drill occasionally, use a spur. You could even use a fused spur with a neon FCU somewhere visible so you don't leave things switched on in the loft.

The "plug" socked is going to power a TV distibution loft box which i know will draw next to nothing power wise.
I just wanted to know whether it is permitted or not?

Yes it is. Now stop asking the same question

If you are so sure prove it with an extract, oh rightous one!

 

[ban-all-sheds]

Who are you asking to prove what?

You can only fit a single socket on a spur unless fused individually.

Not so. You can fit a single or a twin socket outlet
