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

No. They merely change the tolerances. My mains is currently at 242.8v ;-)

I have a relay with a coil voltage of 220 to 230V 50-60Hz which
replaces an old one (240V/50Hz).

Relays are about the most tolerant of electrical devices.
