Energy comparison customers who own older homes might be interested to hear that the government will not achieve its zero carbon targets unless existing housing is given the same 'green' treatment as new build properties.
This is the opinion of Ant Wilson, director of sustainability at AECOM, who said: "If we are really going to get into reducing carbon and hitting targets that we have set ourselves through the Climate Change Act, you have got to get into the existing stock."
However, the lack of a clear definition of what zero carbon entails means property developers are unsure how to tackle older buildings, because, as Mr Wilson pointed out, unless the carbon-emitting properties are knocked down, no number of new, zero carbon buildings is going to reduce the country's carbon emissions.
The government has pledged to ensure all new homes are carbon neutral from 2016.
