I need one of them leccy monitors that you attach to the main wire in the fuse box and tells you the usage in real time.
Also gives historical data.

Been away from UK awhile and lost track of the good ones.
Pen's in UK at the mo, so she can bring it back.

Any recommendations?

There are two main types. One that measures electrons flowing though a cable, the bit they don't tell you is they aren't very accurate and work better at high currents.
More accurate is one that monitors the little light flashes on your meter, the light flashes every time the meter goes up a certain amount. Accurate but it may be a long time between flashes on some.
