It hasnt changed here yet for one reason.
 
Our spec was 240V +/- 6%. but equipment was usually designed for +/- 10%.
There is an awful lot of legacy equipment the was designed to those limits
 
That gives a designed working range of 216 - 264 volts.
 
The new standard is 230V +/- 10% which is 207- 253 volts.
 
If we had changed to 230V then the lowest permitted voltage is BELOW what some equipment was designed to operate on and early electronic equipment with Linear power supplies could fail to work properly. Anything with a Switch Mode PSU should be OK.
 
I believe the plan is to wait a few years before dropping the voltage to the new level by which time the older equipment should be decomissioned.

Voltage didn't change anywhere....just the spec, now single spec across
euroland!! Typical Euro nonsense.

Now spec is something like 230V +/- 10%
