Energy Efficiency

First, I welcome the hon. Lady to the debate. I am sure that she will be a key—and welcome—feature of such debates for the rest of the Parliament. Of course, CERT is already a levy on the energy companies and we have a clear idea of where the money is coming from. She mentions that in Kirklees the scheme is free, and that is an important point. We simply cannot afford to give free insulation to the whole country, even though it worked extremely well in Kirklees. However, through legislation and opening up new markets with new regulation, we can ensure that there is no cost up front to every single householder. Unlike other pay-as-you-save schemes that were trialled by the former Government, there will be no reference to the credit score of the household. It will not be a personal loan, a green mortgage or a charge on the property. What will happen is that the right interventions for that particular property will be delivered and the costs of those interventions will be rolled up in their entirety and repaid through the energy bill for that property over 25 years. If that owner moves away, the cost will simply transfer to the energy bill of the next occupant. If the occupant changes energy company, the cost will simply transfer to the new energy company. We will make sure, through legislation, that it is impossible for a new energy provider to come in and provide energy without taking on the costs associated with the green deal finance. There is a real golden rule.
