British Gas: What is Economy 7? "Check the Economy 7 times for your region using this table below" [many give two or more sets of times, and some rows say "Differs from property to property"]
Ovo Energy: Economy 7 "Economy 7 times differ depending on where you live and which energy supplier you’re with. For example, the seven off-peak hours might be 11pm to 6am, 12 midnight to 7am, 1am to 8am or even 1.30am until 8.30am. You would need to check with your supplier. The hours usually change when the clocks go back or forward – so your Economy 7 times could be 1.30am to 8.30am during British Summer Time and 12.30am to 7.30am in the winter during Greenwich Mean Time." [but see source above re "by supplier" being a possible misconception]
