Do the regs specify whether a neon is required on the FCU for a
boiler, and separately on the feed for a gas hob and extractor unit?

They don't specify a neon must be fitted to anything.

Given that the FCU for a boiler is likely to be left on all the time,
what is the benefit of a neon? Ditto for a hob and extractor unit.

Nothing (AFAIK) in the regs. You'd use a neon on something that was
undesirable to leave switched on and which was not immediately
apparent.

I used one cos I put it next to the boiler which has a blue "on" light and a
green "Burner" light. Very pretty :-)

There's a sort of convention that red lights are used to indicate
faults. Other colours are used for various normal indication states,
with green being a favourate for power on.

I initially used green for power on, amber for 'call for heat', blue
for low temperature warning (frost stat in loft), red for lockout.
