Wow! I thought BAS was the forum pedant but some here have out-BASsed BAS. I'll reword what I said:
230V is the nominal rms voltage, not the average rms voltage.
If the LV distribution system is run for maximum efficiency, the house by the substation gets 253V rms whereas the house at the end has to put up with a variation between 253V rms when the loading is low to 216V rms at times of peak load. The average for everyone is ~ 240V rms.
