What Flameport says goes....
I would never use a G/Y cable for anything other than it's intended purpose.
No matter what anyone else says, bodging it with an oversleeve or a bit of tape is just not right.
Do it right first time, if your short of cores then get another cable.

How many photos cells have an earth wire sleeved brown out there? Loads I'd say...
Would use 4 core these days and not use the earth, strange ay

I keep 3 core flex on the van that has brown black and blue cores for photocells.
... and you would undoubtedly be right, but not just photocells - also timer fans, PIRs, wall stats and various other things. Quite common, but never very 'nice' and no longer even 'allowed' by BS7671
It is a little ironic, but the 'earth' often will be needed (to comply with BS7671), even if it's supplying something Class II. Were not the case, the ideal would be for cables to come with one of the cores a 'neutral' colour (e.g. white), so that it could be sleeved G/Y when a CPC was needed, but sleeved brown or blue if no CPC were needed but a S/L was!
A bit like I just suggested (but white!). However, as I implied, what about the theoretical BS7671 requirement for a CPC to be run to the photocell?
