Lambeth council is helping residents get a better deal on their household fuel bills through the power of collective bargaining.
The Big London Energy Switch sees 21 councils negotiate with energy suppliers through an auction process with the aim of getting a better deal for all participating residents.
It was first was carried out in April and included 2,213 Lambeth households from a total of 26,400 in London.
As a result, nearly 20,000 households in the capital have received an offer that would save them an average of £122 on their gas and electricity bills.
As well as saving cash, residents are spared the hassle of having to shop around for a better tariff themselves.
Lambeth council cabinet member for the environment Councillor Imogen Walker said: “This is an excellent and hassle-free way for residents to get a better deal and the council is glad to be able to help people at a time of rising living costs.”
Energy bills are likely to continue to rise significantly over the coming years, putting many more thousands of people across London into fuel poverty.
The more people who sign up, the better bargaining power the council has with suppliers.
Those who took part in the April auction will be receiving their offers soon. Their decisions on whether to accept the offer must be received by May 20.
For those who missed the April window, the deadline to take part in the next auction is June 3.
Lambeth council will act for anyone who pays a household energy bill in Lambeth.
The auction takes place soon after, with offers to follow.
Registering an interest does not mean residents are obliged to accept the new offer.
