Two-rate (economy 7) meter times can differ, depending on where you live, and the type of meter you have.
Depending on how the meter has been set up, the cheaper overnight rate starts at a certain time eg. 12 midnight until 7am.
Remember, this will change during British Summer Time when the clocks go back or forward. If you, as a Tonik member, want to know the hours for your Economy 7 meter, please get in touch with us here.
