Er, well no.

The entire system switches over to off-peak, or rather just the meter
does. Two dials in the meter which record off-peak and peak consumption
the times of which are defined by a time clock, therefore any
consumption during off-peak periods will be charged at off-peak rates.

This is my understanding also. The extra consumer unit is just there to
provide the convieneance of auto switching a bunch of circuits feeding a
class of appliances together rather than needing to have individual
timers for the each of them.

(it also prevents their use during peek times (assuming there is no
extra wiring to provide for this (i.e. a boost capability) and they are
hard wired)
