A phase modulated signal is sent out on Radio 4 longwave, 198kHz which is
detected by the leccy meter and switches the consumption recorded between
standard and off peak.

Does this directly control the meter switching from one tariff to another?

Correct me if I'm wrong, but I thought all this signal did was to keep the
time clock accurate, and the meter still switches over according to what
time
it was preset at when first installed?

No. Older style two rate meters relied upon a local t/s. Teleswitched
meters use either a mains-borne signal or a broadcast signal. If you
check the tariff, you'll see that the leccy company will give you seven
hours between the hours of, say, midnight and 08.00.
