Which is best, long ring final with 2 spurs or short ring final with more spurs?

Good afternoon, hope you are all well. I have been re-evaluating the number and position of sockets in my bungalow, and considering having a few more added for convenience. Currently I seem to have a relatively short ring with 2 long spurs. If I measure the new route for cables incorporating the existing spurs and new sockets, I anticipate a total cable run of about 100m. From what I gather on this forum this is the limit for a ring final per 100m square of floor. Question is, is this a good idea, or should the ring final be made to run a shorter route and add more spurs, not exceeding the number of sockets on the ring, in order to keep volt drop to within acceptable limits. Not being an electrician I have used online cable size calculators to see if my idea is anywhere close to being ok and they come back with a huge 25mm squared cable. I am clearly out of my depth here hence the question. As always, many thanks in advance. Kind regards, Simon

    Hi Chris, sorry for not making myself clear. looking at my plan i would say the closest description would be of some kind of antler shape, although I wouldn't want to be that animal. fanning out into separate rooms from main hallway. The 5m spurs would come from the tip of the points on the antler, if this makes any sense. Regards Simon




    "Antler shape" suggests radial rather than ring. However, if the ring is passing up and down the main branches of the antlers, with spurs only at the tips, it should be in order.
