Time Of Use (TOU) tariffs apply different prices for electricity at different times of the day. Time is divided into Peak, Shoulder and Off-Peak periods which reflect the level of demand on the electricity network. During Off-Peak periods electricity prices will be cheaper than at other times. Charges are higher in Peak and Shoulder times and lower in Off-Peak times, so understanding the way you use electricity and the available tariff options is important to ensure you get the best value for money.
