You can't *legally* change the times at which you receive off-peak
electricity.

Not strictly true - there`s a tariff called Option 14 available from some
suppliers that gives you 14 hours of "off peak" electricity - from 9pm to
8am and from 1pm to 4pm

Whether this is now classed as a "protected tariff" and only available to
customers who were on it before it was withdrawn to new customers I can`t
say, but I got it in approx December 1999 and went back onto standard
quarterly tariff about 2 months ago when the central heating was
installed.

The interim period from 1999 to 2004 had us using oil filled electric
radiators in a couple of locations around the house, run directly from
the ring main, and they were controlled using cheap digital plugin
timers.

SEC have brought in a tarif called flexi heat
