Generally the guys would make a hole in the ceiling, wire the JB, and

However, some fittings are small and a JB wouldn't go through the hole,
and access wasn't necessarily possible from above.

Don't ask me about regs - there are plenty of folk here far more
qualified to answer you than me - but I can tell you that dinky little
junction boxes are available which are ideal for the purpose. See:

These are smaller in diameter than most, if not all, 12V downlighters,
and will pass through the hole in the plasterboard. They don't seem to
be particularly well known. Neither Screwfix nor Toolstation stock them.

Thanks David. Some of those are used, and you're right about them, but
we have some some lights with even smaller holes, and no JB's would
fit for those. Over 2K spent at Mr Resistor bought some good (and some
less good) lighting, but lots of hastle one way and another as well.
