Off peak electricity

Being a new customer ( I have an Horstmann electronic 7 water heater control fitted ) what are your off peak electricity timings, and switching method used. Should the setting be on GMT/BST or GMT only. My area is SS8 0JN

@lionel7864 Your off peak times are between midnight and 7 in the morning. Economy 7 meters don’t switch with BST so will always be GMT mode.
