HOUSEHOLDS are being offered the chance to potentially save money on their energy bills before the cold snap sets in.

Registration is open for the next Big London Energy Switch, a scheme that exploits the collective buying power of thousands of the capital’s families to force gas and electricity companies to bid for their custom with the guarantee of cheaper tariffs.

The reverse auction, overseen by London’s local authorities, takes place on October 16 and people who sign up will receive an offer to switch contracts that outlines the prices they will pay. There is no obligation to accept the offer and change utility supplier.

Barbara McRae, 85, from South Harrow made a saving in the first round in April.

She said: “I decided to sign up because my bills are getting more and more expensive. “I had the confidence that our best interests were at heart as it was being run by the council.

“I was really very pleased when I heard I had made a saving.

“It was very easy to sign up and switch. If I could do it, then anyone can.

“I would certainly recommend that everyone at least give it a try. There’s nothing to lose.”

Households in Harrow have until October 15 to sign up by visiting www.biglondonenergyswitch.org.uk or call Harrow Council on 020 901 2600.

Leader of Harrow Council, Councillor Thaya Idaikkadar (Independent Labour), said: “The Big London Energy Switch is a simple and effective way to get a better deal on your energy bill.

“Together we have the power to cut our bills with winter round the corner and at a time when the energy companies are putting prices up.

“The more people that sign up, the better deal we can get for Harrow Residents so it’s in everyone’s interests to take part.”

Almost 2,500 Harrovians were among 30,000 people across London who signed up to the two previous energy switch auctions in April and June this year. The average saving per household over the two auctions was more than £100.
