Economy7 times in south east england

Please could you advise when economy 7 low tariff switches on and off in South East England. I understand it is 22:30 to 00:30 and 02:00 to 07:30. Totalling 7 hours. But does this change with the GMT to BST time changes. Or does it remain at GMT the whole year.
ie. in winter it is 22:30 to 00:30 and 02:00 to 07:30; and in summer is 23:30 to 01:30 and 03:00 to 08:30 ?
This is important to know accurately.

Hi @PaulS,

Thanks for your message.

It depends on your meter set up if your Economy 7 hours will change when the clocks change, I’m going to send you an email so we can have a look at your account in more detail. :email:
