I have a socket that's been in the loft since we moved in, it's taken off the upstairs lighting which I know is not good. It's only used rarely (if ever) for very low power stuff, I intend to fit an FCU for it to avoid anything substantial ever being plugged in, which it does not have, 5 amp I guess. Anyway, my question is, is there a combined single socket and FCU available, as it would be very easy to simply swap the single socket faceplate for one of those, or do these not exist, can't seem to find any. Thanx.
