This rate is used for the 20 hours of cheaper electricity in any 24 hours. It can be used for approved central heating and hot water systems.
For the remaining four hours, in any 24, the energy supply to your heating and hot water will be interrupted.
These times are programmed in your meter and unique to each meter. To find out what these times are, please call our Customer Care team on 505460 or send an email to jec@jec.co.uk.
