It's quite a balancing act as with the "E7" tarrif the standing charge
and peak unit cost is higher than the normal "domestic" charges. So
the amount of power you need to use in the off peak period is related
to how much you use during the peak period.

Using NORWEB/Energis/PowerGens old E7 and domestic tariffs you had to
use 1.47 units to save the increased standing charge and an additional
0.21 units for each peak rate unit used to save the the increased peak
rate cost. At reasonable useage rates (15 units/day) you need to use
about 1/4 of that power in the off peak period. ie 4 units off peak
and 11 peak just to break even.
