Homeowners may be unwilling to make the leap to 'zero-carbon' homes and are worried about the potential costs involved, a survey has found. Financial Times

The study, commissioned by the National House-Building Council, found that most people were unaware of what constituted a zerocarbon home and were put off by their appearance when shown designs.

About 60% of people polled preferred traditional-looking houses. More than 30% said they had no interest in buying a house with built-in equipment to generate energy, such as solar panels or a mini wind turbine.

Many raised concerns over other potential features, including windows that do not open as far as usual to ensure that the home leaks less hot air.

The government has pledged that all new homes from 2016 must be zero carbon.
