I have 2 meters for electricity. They have different rates and one is for the storage heating. This seems to be attached to an old timer which is set to come on at night but also 4 hours during the day. I would like to alter that but not sure who has responsibility for the timer, us or SP? Has anyone dealt with these before?
My parents old house had twometers like that. Whenever the second meter clicks on you are getting cheap power so enjoy it. I don’t know who could alter the timing. If you ask someone they will probably replace the system with a single modern meter.
