Prospective homeowners should have some idea of what they'd expect to pay for their cheap energy use when they buy a new home.
This is the opinion of Fraser Winterbottom, chief operating officer of the Energy Saving Trust, who told Which? that properties for sale should display their annual energy bill alongside its price.
Such a move could give the energy efficiency of a home more significance and the greenest homes could become more attractive to buyers.
This could lead to more people making energy efficient improvements to their houses before they put them up for sale, Mr Winterbottom pointed out.
Currently all homes that go up on the market are required to show an Energy Performance Certificate, which grants an energy rating relating to the energy efficiency of the property.
