The government's pay as you save (Pays) energy efficiency scheme has been hailed as a great way for consumers to save money on bills from energy suppliers.
Whatgreenhome.com said the cheap energy scheme, which allows homeowners to install microgeneration technologies and pay for them using savings made from future reduced bills, is a "very promising" initiative.
The website's founder Gordon Miller, said the scheme, which is currently being trialled in around 500 homes across England, should not be halted if there is a change of government.
He also pointed out that the trend for eco-friendly home improvements will continue to grow this year, as long as customers receive some type of benefit.
"People will always react to money; that is the main driver for the CO2 argument - you have got to incentivise people," Mr Miller said.
The £4 million Pays scheme has been extended to homeowners in Birmingham, Sunderland, Stroud and the London Borough of Sutton, who will all test out new ways to finance whole house energy makeovers.
