The Home Energy Conservation Act (1996) charged Scottish local authorities with achieving ‘substantial’ improvements in domestic energy efficiency. The Secretary of State at the time issued guidance that this meant around a 30% improvement over 10-15 years years, the target figure that English and Welsh authorities adopted. Unfortunately, in Scotland, local authorities managed to negotiate their targets down to as low as 9%, these targets were not mandatory, and there were no new resources allocated to local authorities for fulfilling HECA. For these, and other reasons, HECA is not fulfilling its potential.
