Since Troubled Tarts said that the E7 times were between the stated times, and my E7 period finishes AFTER the stated end time, they are wrong! And confirmed by dunstonh.

Something's very wrong there. Your off-peak times should be overnight and should be a single period of 7 hours if you're on an E7 tariff. It seems like you're reporting a reversed tariff, which is good for you if true! And since you still seem to be confused, as has now been said several times - E7 times do not change to summertime - they stay as they were. So 00:30-07:30 GMT and 01:30-08:30 BST or 00:30-07:30 UTC all year.

Another word of caution … Some IHDs at least show a countdown to a tariff change. The times are the ones from the Tariff Switching Table, so nominal. The actual timings will be a few minutes later. The IHD will probably show an alarming red light when the restricted circuit is energized, just to indicate 'much more power being drawn than usual', so that's a good indicator of the ALCS timing. I'd make sure by watching the meter itself when I'd located the 'current tariff rate' or similar screen.

I'm assuming the peak times in the previous message were a typo by the OP

My IHD countdown reflects the ALCS times and not the tariff schedule time. I know this, because once my tariff schedule went out of sync when I was with E.On and the countdown ended when my ALCS switched off but my tariff price switched 10 minutes prior to that. Luckily, it was rectified.

As above, don't have ACLS.

The times I quoted are what perplexityAI told me the funny html style tariff download stated. The same output shows my 00:30 to 01:00 usage being in a slot labelled 00:00 - I guess this is GMT 23:30 - 00:00 and is time stamped with the end of period time?

It would be a pain if the tariff didn't switch on the half hour as obviously the data I can check is half hourly.

I will change everything now to turn on at 01:30 rather than 00:30 but as I use about 16kw in the first hour of the cheap period and the day night rates are supposed to be 7p/40p, getting this wrong for 2 months will be very costly unless I can convince them that the failure to bill me or inform me of the times mean I couldn't possibly have known.

FWIW, I use the Bright app and that shows my tariff times pretty clearly.

I'm not sure I understand this. It might be clearer if you cut and paste (some of?) the actual data if you want help understanding it.

If you're talking about the rate switching a few minutes after the stated times, this is due to a randomisation feature in the meter, designed to avoid all the storage heaters etc in the region all starting at exactly the same moment and causing a brown-out or worse. I don't have an ALCS either and what I do is just start everything ten minutes after the official start of the cheap period, and finish ten minutes before the end. That seems to work for me.

Sorry if I am not being clear

This is my usage file extract. Everything turns on at 00:30 BST hence the 7.963kwh is what is actually used between 00:30 and 01:00

01/05/2026 23:30	0.045
02/05/2026 00:00	7.963

To clarify, perhaps: the meter works on a bucket principle - it starts filling up a bucket, then after 30 minutes records its contents and the time of the record. Some utilities alter these data so that the timestamp gives the bucket-filling start time, i.e. half an hour before the meter's actual timestamp. Some go further and change the timestamp to local - ATM that's BST. Your example shows that the timestamp hasn't been altered in either respect.

It's always fun to see what happens at the start and end of summertime, when figures massaged like this suddenly don't fit the 48 buckets per day scheme. Making simple spreadsheets match these (unnecessary?) changes can be a mind-bending biannual exercise.
