Residents have just days left to be in with the chance of slashing their utility bills.
The first Cambridgeshire Energy Switch was launched in February this year and saw more than 400 residents switch their energy supplier and save an average of £224 each per year.
The second switch scheme is being launched later this year and residents - and businesses - have until Monday, June 9 to register.
A spokesman for East Cambridgeshire District Council said: “Now there’s another opportunity for households to make these savings with the scheme.
“The more residents that sign up the better the deals are likely to be.
“Following the introduction at the end of last year of a bespoke tariff being used specifically for collective switchers, big competition amongst energy suppliers for the collective group is anticipated.
“Currently suppliers are only allowed to have four core tariffs per energy type, but the collective switch allows a ‘fifth tariff’ to be introduced that wouldn’t previously be available.
“Residents across the district may not currently be enjoying the lowest tariff available and don’t know how to change suppliers or want the hassle of shopping around for the best deal.
“The Cambridgeshire Energy Switch Scheme is being supported by East Cambridgeshire District Council to use the collective bargaining power of residents to bid for better prices for electricity and gas to save households money.
“It’s open to all residents on both credit and pre-payment meters.”
