Octopus Energy has paid out more than £1 million to customers who took part in an innovative new pay-not-to-play scheme.
Households and businesses which reduce their electricity consumption when asked will be paid for every unit they do not use under the scheme, which is being trialled by National Grid. Octopus customers have been the most active among the suppliers offering the service.
The firm said the top households in the scheme have saved as much as £20 since it launched a little over a month ago.
