Having a two-rate meter usually mean that one would pay two rates for electricity, depending on when they use it.
Two-rate (economy 7) meter times can differ, depending on where you live, and the type of meter you have. Normally, the cheaper overnight rate starts at 12 midnight until 7am. If you would like to check, please get in touch with us here.
Remember, this will change during British Summer Time when the clocks go back or forward.
