The UK Government has published 'The Energy Challenge", its review of energy supply and use over the next fifty years. The document is principally concerned with large-scale energy production and consumption - electricity distribution, road transport etc - but also notes:

• The part to be played by "Biomass stoves and boilers provide space and/or water heating from a variety of fuels such as wood pellets, woodchips, logs and non-wood fuels."
• That developing the Code for Sustainable Homes (CSH). Level 1 will require energy efficiency performance above the current Part L of Building Regulations. Level 5 will require that new homes be carbon neutral. (2.16.1). All government-funded housing will be required to reach at least Level 3
• Government intends to introduce energy performance certificates, for both new and existing buildings (2.16.5)
• Government recognises that ensuring full compliance with Building Regulations – particularly Part L on energy efficiency – is an issue. So intends to extend self-certification schemes to reduce burdens on local authorities, and make compliance more likely, and to make it easier for local authorities to prosecute breaches of energy efficiency standards. (2.16.3)
• That Government might make grants or tax concessions available to householders installing low-carbon equipment
