i wish to redesign this circuit to provide several more power points and would like to check whether my proposed design is within regulations. What I foresee is a number of junction boxes wired in series in 4mm cable. From each box would be a single power point wired in 2.5mm T&E cable. In effect, all outlets on the circuit would be spurs.There is nothing in 433.1.204 nor in appendix 15 which forbids multiple spurs. Nor can I think of any practical reason why two spurs from two adjacent junction boxes would be safe, while combining those two into one junction box .

I think I’d get junction boxes to work with the conduit (maybe the wrong thing to spec off but want it all looking neat) A. adgjl Screwfix Select.Now I’m considering using a spur off a junction box, twice. So where the ring runs below the socket locations I’d chop the ring, fit a 30A junction box and take a cable up behind the skirting to the new socket, and I do this twice. I don’t think there’s any issue with me doing this and it’s not against any regs.
The first and most popular is to use 2 30amp junction boxes and the other is to use 2 existing sockets. Junction Boxes: A length of existing ring main cable is traced and cut once the power has been isolated. A junction box is installed at either cut end and a new length of cable installed between junction boxes to create an extension.
