The sector is highly concentrated and consumers would gain from more competition and choice. The Office of Fair Hading has called for improving the certification process for new products, which currently hampers innovation and market entry, and for a single body being given the responsibility for monitoring the quality of insulation installations (OFT, 2012). The government should implement these recommendations without delay. A shortage of well-trained workers in insulation techniques is an additional potential bottleneck. The government is contributing to building up skills by offering up to 1000 “Green Deal” apprenticeships.
