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 :-)

How much power does a neon use when on 24/7, out of interest?

Making a few assumptions such as the strike voltage of the neon is 90v,
and has 100k resistor in series and the mains is DC not AC (bear with
me!)then the current would be 1.5mA and the power 0.36 watts and this
would consume 1 unit of electricity in 2800 hours.
But the mains is a sine wave and the neon is only lit when the peak
voltage is greater than 90 volts so possibly only on for 2/3rds of the time.
Which gets us to over 4000 hours per unit. So depending on your tariff
maybe 20 pence per year.

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.
