The news of a suspected government U-turn on an energy efficiency scheme for homes has resulted in Channel 4's Grand Designs presenter Kevin McCloud joining in widespread criticism. It is said PM David Cameron will block proposed mandatory rules on the Green Deal. Mr McCloud said: "Government plans to require homeowners to improve the energy efficiency of their home when they build an extension are about as sensible as sensible gets, especially when the homeowner doesn't have to pay for those improvements."
