Sounds like a problem with the DNO meter/timeswitch not switching off,contact your supplier.

yep, sounds like a faulty DNO time clock.

Switch the storage heaters off manually during the day whilst you wait for the supplier to come round. You might overheat them and trip the overheat - resetting can be easy or a pita depending on which model it is.

Do you have 2 seperate meters? Ive been to a couple of these jobs where theyve just been on the normal meters.

Also some suppliers will do a heatwise plan where they spread the cheap rate through the day. Much better for storage heaters, and easier to test as you dont have to be in at midnight.

Thanks for your replys guys the meter is geared up for e 7 I've spoken to supplier they are monitoring the next 7 day usage but today I went to her neighbours flat hers is the same she got told to put the switch down at bedtime for the water and turn it off when she gets up but that can't be right can it through e7 it should turn on automatically at 12 and go off at 7 should I phone supplier back to come and check meter many thanks

I know very little about the different E7 systems that are available, or the controls that are provided these days. But i was just wondering if this time clock in your mothers system had an over-ride switch, and if so, has someone inadvertently flicked it to the ON position??
Worth a check at the very least, it would explain the constant supply to the heaters....

Some new meters have a fifth terminal for a storage heater sub main (neutral tail just goes to the neutral block) and it all works without an external contactor. The current to the fifth tail is switched on and off in the meter and though the time this happens can vary it shouldn't be more than an hour early or late.

I would assume the meter is faulty
