§ Mr. Hanson
To ask the Secretary of State for the Environment what assessment he has carried out on the number of inquiries received by private companies from members of the public in respect of the energy efficiency voucher scheme; and how many vouchers have been presented to date. 
§ Mr. Clappison
A full assessment will be carried out in the summer when further research results have become available. Preliminary results show that the promotion—which was supported by the private sector, and included the industry's own advisory service—successfully maintained awareness of energy efficiency within the "Wasting Energy Costs the Earth" campaign. So far, there have been almost 12,000 consumer responses, either through presentation of vouchers or through requests for advice.
