Almost all homes can benefit from further insulation, whether this is through taking relatively simple actions such as topping up levels of loft insulation and filling un-insulated cavity wall, or though more difficult or expensive steps such as insulating floors, installing high efficiency glazing or fitting solid wall insulation.
We have made good progress insulating lofts and cavity walls with five million homes insulated between 2002 and 2008 and a commitment to insulate a further six million homes by 2011. The Heat and Energy Saving Strategy (HESS) consultation published in February sets out our ambitions to insulate all of the remaining lofts and cavities where practical by 2015. The HESS also explains the approaches we are considering to make it easier for households to take on more difficult or expensive forms of insulation and thus gain the benefits of reduced energy bills and a warmer home.
For the period between 1997 and 2001 on average around 250,000 homes were insulated per year (loft and cavity wall insulation).
From 2002, with the introduction of the Energy Efficiency Commitment (EEC) figures rose. For the first period—EEC1 which ran from April 2002 to March 2005 around 1.9 million homes were insulated (roof, cavity and solid wall insulation). For EEC2, which run until April 2008, around 3.3 million homes were insulated.
In 2008 my right hon. Friend the Prime Minister made the commitment to insulate a further six million homes by 2011 and the Government are on track to deliver this target. In April 2008, the Carbon Emission Reduction Target (CERT) replaced EEC with a new more ambitious target. In the year following April 2008 around 1.5 million homes were insulated by CERT and other programmes. In addition, as set out in the Low Carbon Transition Plan, the Government have committed to extend CERT to the end of 2012 with an even stronger focus on delivering insulation.
