The Energy Efficiency Advice Centre (EEAC) is part of a national network of 52 centres set up by the Energy Saving Trust to help reduce carbon dioxide emissions. The EEAC provides free and impartial advice to households on reducing energy use and bills through energy efficiency measures, grants, and discounts. Common measures like loft insulation, cavity wall insulation, and draught proofing can save households up to £100-150 per year with payback periods of 1-5 years.
