New build homes could become more popular as buyers shift their attention to energy performance.
Rising fuel bills could persuade people to choose more eco-friendly homes in future, the National Home Improvement Council (NHIC) has said.
This week, Future Friendly revealed that more than two thirds of people want to improve their environmental credentials, but are still neglecting to do everyday things that can make a difference, such as using an energy monitor and installing loft insulation.
Liverpool was the top region for paying attention to insulation, while people in Manchester were more likely to keep an eye on their energy usage.
Andrew Leech, director at the NHIC, said older houses are often much more expensive to make eco-friendly than new homes, which are often already built to the latest environmental specifications.
He added: "The Green Deal really is the crucial element in all of this and at the moment it is in the discussion stage.
"The consulting documents should be out this month and then there will be a final discussion on that which will take it through to being published in October 2012."
