New house and the garage is "built-in" under our bedroom on the corner of the house. Previous owners have taken a feed from an adjacent room into the garage with a switched fused spur, and then put a couple of sockets on one wall. All in surface-mounted plastic conduit, RCB protected at the CU. I need to add an extra 4 sockets for convenience around the garage. Don't expect them all in use concurrently, so no issue with the 13A fuse on the spur. But I also have the option of bringing the ring down from above, so all the sockets are on the ring rather than a single fused spur. Given I don't need more than 13A, is there any advantage in the extra work of extending the ring? Feels odd having so many sockets on a single spur, even though I know it's safe. One advantage of extending the spur around the garage is I have a single kill switch for all sockets in there, should there ever be a reason for such isolation. Probably overthinking this, what would you do?
