What time the night rate start’s
Wander about night rate, what time is start and time when finished
It depends on your region, have a look here: https://help.bulb.co.uk/hc/en-us/articles/360015855172-What-are-my-off-peak-hours-for-Economy-7-
Also check the time shown on your meter, as explained in the link from jwd2017. Our off peak in winter is 23.30 to 06.30, but BST is 00.30 -07.30. (actual time, not meter time). Our white meter for storage heaters works automatically, but if you want to set timers for dishwashers, washing machines etc., you obviously want to know the actual off peak times.
Also, check the time displayed on the meter for accuracy. Ours is 26 mins slow. So our off peak at present is 00.56-07.56.
