UK: Over 54 000 vouchers have been issued under the Government's boiler scrappage scheme. Around 70 000 vouchers worth £28m are still available.

The scheme, launched in January to upgrade up to 125 000 domestic heating systems in England to cut carbon, save money on fuel bills and sustain work for the heating industry, aims to replace Band G systems.

Utility firms that sell and install boilers (British Gas, E.On, npower and Scottish & Southern) are matching the offering and are giving householders around £800 off the cost of a new boiler. Several manufacturers are also offering deals.

Energy and Climate Change Secretary Ed Miliband said: "The boiler scrappage scheme has proved incredibly popular and with energy companies and manufacturers offering deals as well.

"The Government scheme has truly kick-started a national programme of boiler replacement.

"The scheme is helping householders to save around £200 a year off fuel bills and reduce emissions while helping to sustain work for the 130 000 installers and up to 25 UK-based boiler manufacturers throughout the economic recovery."

The Energy Saving Trust, which runs the scheme on behalf of the Government, said it has received up to 5000 enquiries a day nationwide. To-date, there are have been around 400 000 enquiries.
