Thousands of people could now be enjoying cheap electricity thanks to energyhelpline.com's Huge Switch campaign.
In the five days since it launched, energy customers collectively saved three quarters of a million pounds on their bills.
So far, more than 4,000 consumers have switched and the average saving is £184.
This includes £139 off their bill and £45 cashback.
It means the average family could pay less than £1,000 for their energy next year if they take advantage of the cheapest tariff on offer through the scheme, which comes from First Utility.
This is £61 cheaper than than the Co-operative Energy deal available through Which?'s Big Switch campaign.
Director at energyhelpline.com Mark Todd said that although Huge Switch is due to close today (May 28th), he wants it to stay open longer.
He added that the company has sacrificed its own commission to give customers these savings.
Mr Todd said: "Energy customers need to act now to get the best deals while they're around and avoid the likely price rises that are expected later this year."
The initiative also has the support of secretary of state Edward Davey, who spoke about the deal in parliament last week.
He stated: "I want to help make collective purchasing become a permanent feature of the UK energy market."
Through Huge Switch, cheap energy deals are also available from the likes of EDF Energy, Scottish Power and Sainsbury's.
