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.
If the hon. Gentleman will allow me, I shall continue. I am risking scrambling my speech by jumping ahead, but this is a really important point.
I will give way.
We cannot guarantee that this will be the case in all instances, because behaviour change is also relevant, but the guiding principle is that the savings in every household that receives such interventions on the pay-as-you-save model must always be greater than the financing costs. The householder, be they in rented or private accommodation, should see not only an increase in the insulation in their home, a reduction in their carbon emissions and an increase in warmth and quality of life for them and their family, but—and this is an important point—a reduction in their total energy bill. That needs to be put clearly and fairly on the bill. We must scotch the idea that the green deal is a loan, a mortgage or a charge, because it is not, and it is really important, in order to get consumer confidence, that we communicate that message.
I thank the Minister for giving way. I hear what he says, but is not the danger, as the hon. Member for Brighton, Pavilion (Caroline Lucas) has said, that this will be seen as a loan? Will the most vulnerable people, in particular, who find themselves indebted from a whole range of loans, not see it at as one more loan and choose not to take it?
No; I hope that by the time we have finished explaining it properly and getting over this new paradigm, it will not be seen as a loan because it is not a loan. I hope that the hon. Gentleman—and, indeed, all Members—will join me in explaining that to our constituents. This is a really fundamental point, because he is absolutely right that if people perceive it as a loan, which it is not, there will be a reluctance to take it up, particularly in the current environment. There is another element. We accept that for the poorest in society, who cannot make the savings because they do not have the cash to heat their homes in the first place, there will be a need for direct subsidy or intervention. It is on those people and the hard-to-treat homes that we want to focus the ongoing obligation on the energy suppliers.
