The document provides guidance on new HECA (Home Energy Conservation Act) reporting requirements for local authorities in the UK. It notes that the Green Deal has changed the policy landscape and local authorities now have opportunities to flag energy efficiency opportunities using localism approaches. The guidance specifies that HECA reports are due by March 2013 and every two years thereafter, and should outline local energy efficiency ambitions and priorities, measures that take advantage of financial assistance programs, and timeframes for delivery while working with national and local partners.
