So I slapped a clamp meter round one of the meter tails, and switched
off various bits to see what showed up...

Interesting. So, if I am reading these figures correctly, that is a
total draw of 6.07 amps. What I don't know, is how to convert that to
KWph. In other words, if you used exactly 6.07 amps for one hour, how
many units of electricity would that be?
