18th question.

Hi all, any comments welcome on this one.
Is it still acceptable to have a socket outlet for a specific use not rcd protected under the 18th?
I fitted a single 13a socket outlet recently in a loft space for one of my regular customers, it is to supply a security camera system and the suppliers asked for a socket to be provided. It is supplied from the first floor lighting circuit which doesn't have rcd protection. (16th. ed. board) There is not the slightest chance of the socket being used to supply anything else and I would like to issue a mwc stating that the socket is only to be used for this specific purpose. If it's a major issue I could get back to the customer and arrange to fit an rcbo but I don't really think that is necessary? Thinking now about going back to change socket for an rcd protected one?

    Or (playing Devil's Advocate - following on from a discussion with Graham) - instead of using an ordinary 13A socket, fit some sort of joint box to terminate the fixed wiring, then run a short length of loose flex to a trailing socket (e.g. https://www.tlc-direct.co.uk/Products/TLRS1.html). By BS 7671 definitions the trailing socket is a "connector" rather than a "socket outlet" (the latter has to be connected to the fixed wiring to meet the definition) - hence the additional protection requirements for sockets don't apply.  (why isn't there a tongue-in-cheek emoji?)
