I am about to put in a new ring main run in conduit with single cables, obviously the live and neutral will be 2.5mm but I am unsure what size the earth conductor should be, you would think that it should also be 2.5mm but in 2.5 twin & earth cable it is much smaller, so do I use a smaller earth?.

Use a minimum of 1.5mm cable for the earth.
Personally I always use same size earth as other conductors when using singles. But 1.5mm would be allowable for a normal sized ring circuit.

I don't because I'm a tightarseand a bit lazy! 1.5mm doesn't require as much effort to strip as 2.5mm!
Now that *is* lazy ;-)
(I take it you are using wire strippers and not your teeth?)
Ever heard of decent wire strippers? ;-)
With a good pair of 'automatic' strippers the difference is insignificant surely. You don't use cutters or pliers to strip your wire do you?

Close, a pair of CK sensoplus sidecutters.
You are joking right?

All the pros nick the copper, it wouldn't be right otherwise! I usually oversize the cable to start with so that the chunk you take out of the cable upon installation is allowed for in the design stage, isn't that how you're meant to do it? ;-)

I used to have an automatic wire stripper, but he was useless, so I sacked him! My current strippers aren't automatic and still require me to do a certain amount of the work.
I've used all sorts of stripper, manual and automatic. However, one type I always come back to is the type illustrated below.

It's more speed and ease, though. I'd cut, say, 6 wires for a 13A socket and be able to strip the lot in under 10 seconds without even thinking about it. Maybe my cutter technique is faulty, but it would take me about 10 seconds per wire to do it that way.

Depends what you're used to, I can work with a pair of cutters as strippers with relative ease, but that's because that's how I've always done it. If I were only doing it on the odd occasion I probably would be quicker with the strippers.
I still use an old pair of manual wire strippers made by bib, remember them ?,. Cant get on with the auto strippers we have at work. But might get a pair of those screwfix ones.

I've also got many - probably an example of just about every type, but my favourite by far doesn't appear to be made anymore - or at least I can't find it at RS etc. It's a sideways on device with four holes for different size ranges, and will do the smallest I ever use in electronics up to
2.5mm. I've not found any 'auto' type that doesn't need adjustment over a range of cables, so rather defeats the object.
Takes alot to beat:
snipped long line
Those are the ones !
