not really the radials are on the kitchen at present and everything else will be new as i wont be touching the the kitchen for a while, so there are 6 sockets in total all running from one fuse somewhere via junction box's trouble is i cant put them into a ring so not sure what to do with them???????worse case i will have to chase out the kitchen walls which are a flat roof with no ceiling access.
What about the rest? espcially RCD rating to what i gave

sockets in any form of radial no matter how it spurs can be put on a 20A breaker if the cable is 2.5mm
normally you would use something like a 80A current rating 30ma trip rcd
generally i would say that all downstairs sockets should be on the rcd expect possibly one specifically for the freezer
whether you put the upstiars sockets on a rcd is your choice
