A number of energy companies will be giving their customers money back on their bills for reducing consumption at certain times this winter.
The National Grid announced an opt-in "Demand Flexibility Service" that will see households paid for off peak use. The trial, which will run from November until March of next year, could save the typical household £100 this winter.
Households need to have a smart meter to opt into the National Grid trial. It has been launched to preserve energy supplies and to reduce the risk of planned three-hour power cuts if there is a shortage of gas.
