Several energy suppliers are taking part in the National Grid Electricity System Operator (ESO) trial which could see households paid for reducing electricity use during peak hours.
The scheme - called the Demand Flexibility Service - was rolled out in November, and is available to those who's supplier has signed on provided they have a smart meter.
The ESO will send notifications to customers during busy periods, asking them to switch off appliances for which they will then receive money back on their energy bills.
The trial will run from November to March, with households being paid around £4 for every unit of electricity that they reduce their consumption by during specific times - although the exact rate depends on your supplier.
It comes after the ESO warned that three-hour planned blackouts may be required if contingencies such as this trial were to fail, however they have said that this is unlikely.
Recently, major suppliers British Gas and OVO signed on to the scheme, allowing selected customers to access the money-back trial.
Raman Bhatia, CEO of OVO, comments: "We're pleased to be joining the National Grid Electricity System Operator's Demand Flexibility Scheme and launching another trial which rewards customers for their efforts in making small but significant changes to the way they consume energy."
Chris O’Shea, British Gas chief executive told the PA News agency: "We are exploring how to make this scheme work best for our customers so that it fits in with their habits around the home. This approach to help manage residential electricity demand is likely to become a major feature of the market in years to come."
