That's better, however are you aware of the requirements for non-RCD protected cables?
To achieve your non-RCD radial for FF and boiler, the cable must either be
Surface mounted
In steel conduit
Have an earthed metallic covering (ie SWA, pyro, or Ali-tube)
If you don't want to do any of that then just use an RCBO - it'll still be on an RCD, but not with other circuits.
I really really don't like ring final circuits, especially in a kitchen. How are the loads going to be physically located around the room (we can see the W/M, but what about the toaster, microwave, kettle, George Formby grill etc)? If they are evenly split, how about using two 20A radials? This will mean there's no chance of overloading the cables, either with bad load spreading or a break in a ring, and will make adding extra sockets etc in the future MUCH easier.
Good luck with the BCO mate - take 'em to court if you need to.
