Thousands of old, stone-walled homes could end up rotting under government plans to make them more energy efficient, landlords have warned. The Countryside Landowners Association said cladding homes in concrete to insulate them would have an effect “like a lettuce trapped in a plastic bag”. Under new rules, every rental property in England will have to qualify for an Energy Performance Certificate (EPC) of grade E or above, if it is let after April 2018. Unlike modern homes, which have wall cavities which can be insulated, older homes have solid walls. Matthew O’Connell, from the CLA, said: “As soon as you cover a stone wall with cement render or impenetrable material you will get damp, mould and condensation. If there is timber it will rot. The walls will become sodden.” The CLA said the government system for measuring efficiency was “failing to accurately reflect the energy efficiency of traditionally built homes”. A separate report by the Green Building Council said 25 million homes – one a minute – will need insulating by 2050 if the government is to meet its carbon reduction commitments.
