I heard that UK mains voltage was reduced to harmonise with Europe..
if true when did this happen and what is it..?

It was reduced on paper only:

- the old voltage was 240/415 V ±6% (226-254 V for single-phase)
- harmonised voltage is 230/400 V +10/-6% (216-253 V ditto)

But does the change mean that somebody out in the sticks who finds
that their supply often drops to 220V will be stuck with it, but in
days of yore the Electricity Board would have had to fix it somehow?
