Brits considering buying a conservatory or upgrading their loft space to include a roof light may wish to ensure the improvement is energy efficient, after recent comments from the Energy Saving Trust.
A spokesperson for the body stated it should not be possible to sell or rent a home that is not up to scratch in terms of environmental friendliness.
She explained any residence on the market now requires an Energy Performance Certificate, which gives those looking at it information on how eco-friendly it is.
"The Energy Saving Trust is advising the government that it should not be possible to sell or rent a home that is F or G-rated from 2015," the spokeswoman stated.
Global warming and changing weather patterns is threatening the UK and much of the world and the regulation would force people to take action, she asserted.
According to the Climate Change Act of 2008, the country must cut its greenhouse gas emissions by 80 per cent before 2050.
