To ask Her Majesty's Government further to the Written Answer by the Minister of State, Department of Energy and Climate Change, Joan Ruddock, on 12 November 2009 (Official Report, Commons, 668W), whether the Homes and Communities Agency keeps a record of the ages of appliances replaced; and, if so, whether it is summarised and published. [HL2184]

While the Homes and Communities Agency administers the renewable construction demonstration project (RCDP), it has no involvement in the delivery or monitoring of the CERT (carbon emissions reduction target) carbon saving obligation on energy suppliers, and it is through CERT (rather than RCDP) that energy suppliers subsidise the cost of the most efficient domestic appliances through appliance trade-in schemes.
