I'll be changing my CU on the weekend as one of my assessments for the NIC to look at. All the sockets on the ring, upstairs & downstairs, come from a single 32A circuit breaker in the CU. I was going to put these on the RCD side of a new split load CU but now I'm thinking it might keep nusiance tripping. What do you think ?
New CU, one 32A breaker for all sockets !!

You must put the circuit on the RCD side unless you can make the argument that there are other sockets more likely to supply equipment outdoors that are RCD protected (RCD sockets near doors/windows...).
Can't you split the ring?

Personally I (and many others) RCD protect all socket outlets.
It would be better if you could split the ring, but I can not see grounds for non compliance if you leave it as one ring on the RCD.

Yes - it unofficially gives you supplementary protection against direct contact from faulty hand - held appliances (worn flexes etc)

No - as said above they have to be on an RCD if they can reasonably be expected to supply equipment outside the equipotential zone.But this generally means all sockets downstairs in a typical house.
You will not go wrong with putting them all on the RCD though!
Providing you IR tests are ok then there shoulnd be no more tendancy for nusiance tripping than in a standard 2/3 ring split load setup.
The only difference is if a fault were to occour then you can not narrow it down to just one part of the house.
Re: RCDing all sockets, Nowt wrong with carrying out installations to a higher standard than BS7671 demands

I thought ALL sockets (domestic anyway) should now be RCD protected? 411.3.3 unless they were for a specific piece of equipment, eg fridge/washer?
Shock! How ever did that post rise to the top of my list, never noticed the date!
