Borrowed neutral

[johninleeds]

I'm trying to install a spur off an existing lighting circuit.
I thought I would be able to replace a single switch with a double and use the new switch for the spur.
However the builder hasn't brought the Neutral down to the switch, it's up in the ceiling and I can't access it, the floor above is tiled.
I've seen references to "borrowed neutral" and I can probably pick up a neutral from a ring circuit used for tumble drier/washing machine
Is this allowed and will there be any problems back at the fuse box??
Alternatively are there any "trick of the trade" that will sort out this problem??

Many thanks

Glenn, do you fancy asking the OP if us two can go around and have a look? Bet we could sort this out in less than 2 hours, including testing and cert!

Aye, the OP wont be back lol.

He'll crack on with the work, not certify it and the client will be none the wiser...another day in sparky land then.
