Seems fair enough to me. Also suggests you're getting E7 up till 08.00
now....

It's a bit like BT or some [other] ISP changing the times.

No it isn't. You're getting E7 for a seven hour period within the wider
time envelope as published by your electricity supplier.

But you need to know in advance what period you will actually get so
you can set the appliance timers properly.

Yes, that's the point. Storage heaters are OK, of course, but it is useful
to know when the rate applies. That 'time envelope' is OK for load
management and still supplies the circuit switched by the meter but things
like the washing machine...
