He's in the UK not the USA so you can rule out that problem. We don't have centre
tapped 240V.

That's no guarantee at all.
I'm not an expert in power distribution, but a failing neutral
can wreak havoc even without centre tap.

His 240 volts are likely to be one leg of a 380 or 400 volts
3-phase system.
Kill it's neutral and the lights all shine. Briefly :-)
