Thank you. Can anyone advise which is BS standard is teh relevant one?
The junction box looks rather dated, being dark brown plastic rather
than the typical modern white type. But it does say "30A" on the back.

Should the junction box be screwed to a joist? (It is under the
floorboards, lying on the lath and plaster of the ceiling below).

Hi Harold,
The Junction Box sounds ok. Doesn't really need secured to the joist.

As far as the tightness of the connections are concerned.. is the box
in the roof space or is it under floor boards in a room?

If its under floor boards then vibrations from people walking could
contribute to loose terminals. it wouldn't do u any harm giving then a
tighten.. BUT... be careful not to over tightn as you could break the
screw, wire or jump threads.
