You're correct, it is a 15A MCB, I confused it with the cooker MCB. I
thought fitting an FCU would be better so that if the central heating
ever fails and we need emergency hot water I can isolate the additional
socket and temporarily reconnect the immersion heater.

Not quite sure how an FCU would make that easier.

If you really want that, fit a socket in the airing cupboard so the
immersion can be plugged into that. Wire the new bedroom socket in 1mm
flex fed from a plug too. Then all you need to do is swop the plugs.

I hadn't thought of doing it that way, I just prefer hard wiring,
feels like the 'right way' to do it.
