Everyone seems to be making all sorts of assumptions/guesses - which is hardly a basis for good advice, let alone for criticising others. It could well be a ring final, but, if it is, we appear to be talking about 'a spur from a spur' from that circuit - which, of course, would be non-compliant unless there were, indeed, a 13A fuse prior to the outdoor socket. We also don't know what cable is connecting the main circuit to the outside socket. If it's 2.5mm² then, again, just from the CCC viewpoint (apart from the informative Appendices of the regs {aka 'good practice'?} and the matter of point loading of the {assumed} ring), it would need to be protected by something more modest than a C32 if it was going to be supplying more than one socket.
Nope. Of course, they might be OK on at least some of the circuits.
Quite so - albeit, as I implied in my last post, not necessarily impossible. (as I said, we seem to know nothing about cable sizes!).
It could - although, as westie is always pointing out, nothing says that the Ze of a TN-S supply has to necessarily be anything like as high as 0.8Ω.
