The Energy Efficiency Commitment (EEC) requires energy suppliers to achieve ever more challenging targets for the promotion of household energy efficiency. It has done so very successfully and in a cost-effective way. Three reports on phase 1 of EEC, which concluded in March 2005, have been published to date. These include one by Ofgem, the scheme administrator, and an external evaluation commissioned by DEFRA. The reports are available on the Department’s website: http://defraweb/environment/energy/eec/index.htm.
The data show that EEC phase 1 has exceeded its targets. Measures such as loft and cavity wall insulation are saving 0.4 million tonnes of carbon equivalent per year. Consumers are benefiting by £9 for every £1 they spend, and consumer bills are expected to fall by £3 billion over the period up to 2020. Most low income households and more than two fifths of all households in Great Britain have directly benefited from EEC1.
