Dr. Brian Motherway:

Approximately 20% in the warmer homes scheme and approximately 10% or 12% in the better energy homes scheme. Every day of the week we have large numbers of inspectors inspecting homes and we deregister contractors who are persistent offenders. While this can be controversial because one might be putting somebody out of business for a couple of months as a penalty, we value quality. We are also active on the demand side. I hear anecdotally about cases where people employ a contractor they hear of through our scheme but then do a cash deal and forego the grant to avoid paying VAT. If they do that they lose all the quality assurance, legitimacy and come-back that goes with that. We try to encourage homeowners to put value on the quality and accreditation schemes. That is a long-term issue for the whole construction sector in terms of building markets in areas where there may not have been much activity in the past.
