Economy 7 clock wrong

[Akustik]

My Economy 7 night rate is from 00:30 to 07:30, but the meter is switching circuits at around 00:06 instead. When the switch happens 25 minutes earlier, all my Economy 7 connected appliances such as immersion heater and storage heaters turn on during the day rate for about 25 minutes. That means I'm using 7kWh/hour of energy for these 25 minutes at day rate. I believe this is costing me about £10-£15 per month extra due to this issue in winter. I believe this was the case before I was changed to a smart meter and it was not corrected at the time.

Here's the dfference between kWh and £

I have contacted my supplier Octopus twice now, once a year ago and once this week. They've both times given me roughly the same response of "not their responsibility" (see below).
I believe you reported the same issue back in 2024, and we did not hear back from you ever since, but from what you have said, it sounds like your storage heaters are starting to draw power a bit earlier than the designated Economy 7 hours. Unfortunately, we are unable to adjust the timing of the Economy 7 hours as they are set by the electricity distribution network.

However, I recommend checking with your electrician or the manufacturer of your storage heaters to see if there’s a way to adjust their settings. They may be able to help you manage when they turn on to better align with your tariff.
I contacted my electricity distribution network (UK Power Networks) and they were adamant it wasn't their responsibility but that of the electricity supplier.

Whose responsibility is this ultimately and should I be pushing the energy company to come sort this out?

can you post a pic of your meter and also what you believe is switching the heaters on.

I suspect 70% of the UK have a misalignment !

May not be worth duplication of effort?

Yes, I guess that one hit first, thanks.

They switch on automatically before the rate changes - the circuit gets turned on, I assume by the meter - I can see a countdown to the rate change on the meter. I see the kWh usage jump when everything switches on before the rate changes.
As the other poster said, I've submitted this on another forum and people there seem to know about the problem.

That, suggests your off-peak items, are connected to the peak supply from the meter, but switched by a time-clock which is your property. It is this last item, which is out of adjustment, and needs to be corrected, by you.

Try posting up a photo of the area around your consumer unit, where your fuses/MCB's are located.

This

is the interesting bit, the smart meter does the timing, there are two lines from the meter, one permeant line and one only line during the off-peak.

So it would seem something wrong with the way the two supplies are connected on your side. It would seem the time clock is yours, not the DNO's, but as said more pictures should clarify.
