People in the London borough of Enfield looking to compare energy rates from suppliers could save nearly £5 million by pursuing efficiency more effectively.
The borough is the worst-performing in London, but a drive to install energy-efficient measures such as insulation could save millions for nearly 110,400 homes in the region, reports the Enfield Independent.
Joan Ruddock, the energy and climate change minister, called on Londoners to take greater advantage of the various government payments and benefits that are available to help people make their homes more efficient, reducing energy bills and carbon emissions.
Ms Ruddock told the paper: "There is a fantastic opportunity for London residents to save money off their energy bills, but often people are unaware of what offers are available to them."
The government has been encouraging widespread energy-efficiency drives since all the major energy suppliers increased their prices last year and while costs have since fallen slightly the government has pledged to insulate every UK home.
