That would work for the total consumption, but if you notice that that is too high, you will still have to run around with a power consumption monitor to identify the individual culprits. Of course, a display saying "you are currently using 1300 Watts" would be easier than having to estimate it from how fast the wheel on the meter is turning, but replacing every meter everywhere is not the most environmentally friendly thing to do either...

Or just the good old method of turning things off individually, one at a time.

I’d think panel support would logically have a probe per circuit, so you could get the complete breakdown if and when necessary.

Though obviously it’s still only on per-circuit basis, and if an idiot wired your house that may be less useful than the platonic ideal of house wiring.

There's an energy monitor with 16 CT clamps included, you put one on each of the circuits coming from the fuse board. 16 is more than enough for most UK houses, which would at least let you know which circuits are consuming the power.
