I thank the Minister for that clarification.
When we are talking about energy efficiency in homes, we need to understand just how big the task ahead of us is. The SAP—standard assessment procedure—rating of UK homes went up considerably under the last Labour Government. To be precise, the average SAP rating, which measures the energy efficiency of homes, went up by 11 points between 1996 and 2010—from an average of 42 up to 53. Over the last five years, the SAP rate increase went up one a half times as fast as in the previous five years and the five years before that. That shows how measures such as Warm Front and CERT—carbon emissions reduction target—which are going to disappear when the green deal comes in, were having some success in ensuring that homes were more energy-efficient.
In order to get anywhere near the sort of targets that hon. Members have suggested that the Government should consider introducing in an amendment to align energy efficiency with climate change targets—which I hope will happen in Committee—we need to move the SAP ratings much further up over the next few years, perhaps to 70 or more on average at band C by the end of the decade. That means making progress getting on for twice as fast as we have over the last few years. That is the sort of ambition that the Bill needs to encompass. My concern—hon. Members have already mentioned a number of concerns—is that it remains unclear whether that ambition can be achieved under the current mechanism, despite the claims for the efficacy of the green deal.
Other Members have mentioned the problem of poorer homes, and private landlords are a particular problem, because they have no vested interest in doing anything about them. I am sure we have all had people coming to our surgeries with horrific stories about windows that do not fit, damp all over the place and so forth—yet the landlord often does not care at all.
Indeed. I welcome what I understand to be a change of heart by the Government about the extent to which compulsion can be used to get landlords to improve their properties. Sanctions on landlords with F and G-rated properties have been mentioned; we could argue about when those sanctions might be introduced, but compulsion to prevent landlords from letting properties below certain minimum energy standards is right. The standards are well below the sort of average rating that we have talked about this afternoon, but they are nevertheless minimum standards. If that is indeed a change of heart reflected in this part of the Bill, I welcome it.
I am sure that the detailed provisions affecting landlords can be sorted out effectively in Committee—but first we have to find the landlords. It was not a good sign that when this Bill was being discussed, another Department helpfully removed the idea of having a landlords register as the responsibility of local government. Without that, it will be more difficult to find the landlords who should carry out these arrangements. I trust that the Minister will have a word with his counterpart in the Department for Communities and Local Government and perhaps think again about that particularly destructive act.
The problem of finance has been mentioned. It is essential to making the green deal work. It is not just a matter of suggesting that the market will sort the finances out one way or another and that competitive interest rates will be charged. We can be fairly clear about how finance for the green deal as it stands, without changes, will turn out, because that is how the market works in respect of the sort of return that can be expected at different interest rates. The rate may well be around 9%, or perhaps a bit less. If we look at what can be got under the golden rule with finance at 9%, we find that it turns out to be very little in terms of improvements for properties to which the green deal and the golden rule apply. Loft cavity wall insulation and draft-proofing are probably the only things that work out at that sort of level. With interest rates at 7%, we get draft-proofing, some glazing, some internal wall insulation. With interest rates at 5%, we may get loft cavity wall insulation, glazing and a condensing boiler. If the green deal comes in at 9%, hardly any of the properties that need that sort of level of serious work—glazing, condensing boilers, perhaps microgeneration—will be touched by the mechanism. We must have a better mechanism for making the green deal work.
The energy company obligation exists as a back-up for fuel poverty and hard-to-treat properties. Hon. Members might have noticed that with interest rates at about 5% or so, solid wall insulation, which is present in about 7 million homes up and down the country, will not be touched. The ECO programme might touch it and might have a substantial hand in dealing with those in fuel poverty. Perhaps they should have their green deal underwritten by the ECO so that they can join in the benefits that other people get.
If we are thinking about how the ECO might underwrite the green deal, it is important to understand whether the ECO will exist to any great extent as a financial mechanism. What greatly concerns me—I hope the Committee will be able to look at the problem in much greater detail—is that as matters stand, DECC has signed up to a Treasury-based cap on levy-based arrangements. Under the present financial arrangements—for the spending round up to 2015—DECC has signed up to a cap on renewable obligations, feed-in tariffs and warm homes discount. That cap is set at £11.8 billion over the whole period, but there is also an annual cap.
The Treasury says that any new initiatives that come in the form of a levy must be financed within that cap. If the Department wished to undertake an ECO programme and it proved to be a levy as defined by the Office for National Statistics, it would have to be found under the present cap. That means either that the Government will have to go slow on renewable obligations and reduce the amount of renewable energy, or that the ECO will prove to be so small as to make it impossible to produce the sort of mechanism that many people hoped for—one for adding value to the green deal, getting on with the hard-to-treat properties, dealing with people in fuel poverty and homes off the grid that need extra assistance to make the green deal work, and so forth.
Unless we get the mechanisms right and have the right finance in the system—and, I would suggest, among other things, unless the ECO works properly—the green deal will not work. I am the last person who would want to see the green deal fall. Because a great deal of work has to be done to make our country as energy-efficient as possible, the green deal has to work. The task of making it work properly is the task of the Committee. I hope the Government will be generous in taking on board those ideas, which will make the green deal work as well as it can to bring our energy efficiency targets as close to realisation as possible.
My hon. Friend raises the interesting point of the possible life expectancy of nuclear power plants. I recognise that there is something of a dilemma in respect of old and new nuclear power stations and predictions of extensions, and that there are issues such as core cracking and whether extensions can be safely undertaken. He makes a fair point, however, that some extensions might be undertaken to bridge the gap. The key point, however, is that one of the best ways to ensure our energy supplies are secure over the coming period and that the generation meets the demand is to ensure that there is less demand for energy, and that the energy we do use is used much more efficiently.
I agree with my hon. Friend that even if we start building nuclear power stations now, there will be a 10-year period before they really start to have an impact, but unless we take that decision now we will face an even greater gap in future, which we will have to fill by some other means. Just putting that decision off until tomorrow will make the matter worse in future.
My hon. Friend is tempting me into an entirely different debate, in which there are very interesting considerations relating not least to a new report on the renewable valuation around our coasts and on our land and how we might be able to use those renewables for our long-term, as well as our shorter-term, future energy supply. I suspect, however, that if I were to address that topic, you might suggest that I have strayed rather far from the issues we are debating today, on which I do want to concentrate, Mr. Deputy Speaker.
Energy efficiency is a crucial component of our future energy landscape. I am pleased that the energy efficiency ambitions that the new Government have set out continue those proposed, and acted upon, by the previous Government. I recognise that the new ministerial team has strong personal commitments to these issues, and therefore energy efficiency has a bright start in terms of ambition and of understanding that this area is crucial. After all, 40% of our energy is consumed in buildings and that represents 40% of our carbon emissions. About 80% of household energy goes on heating our homes and water, and that alone represents some 13% of the UK’s greenhouse gas emissions. Therefore, getting a serious grip on energy efficiency in our homes and commercial and industrial buildings offers potentially enormous, and relatively early, rewards in respect of our overall position on carbon emissions and energy consumption.
However, we as a country face this situation from a poor position historically. It is true that the previous Government made enormous strides in improving energy efficiency, particularly of public sector homes, and homes provided by registered social landlords. The Committee on Climate Change report that was published today conspicuously states that its indicators for activity on loft insulation, cavity wall insulation and energy efficiency in homes were met during the last year of the previous Labour Government. Considerable progress has been made, but our private sector homes remain energy-inefficient. The average standard assessment procedure rating in private sector homes is 49, which is a long way from level that we ought to aim for if we are to have a reasonable expectation that homes will be relatively energy-efficient and will have a low output of waste and energy emissions as far as the activities of the people who live in them are concerned.
We can all agree that this House has substantial energy-efficiency ambitions, that there is urgent action to be undertaken and that a number of programmes are in process and a number of ambitious new programmes, some of which we have heard about this afternoon, could get under way to address those issues. We need to examine whether the ambitions are being met, whether we have the ability to make those changes in practice and whether other things might be done to ensure that the ambitions are realised.
As a small indicator of the difference between ambitions and realisation I shall discuss the new part L of the building regulations, which were published recently. I had anticipated that it would contain new guidelines on the energy efficiency of circulation pumps in central heating. If, as was suggested during consultation by the previous Government, the regulations had mandated new and very energy-efficient circulation pumps, we could have saved as much as 2% of the electricity consumption in households—that could have been done by that measure alone. However, the new regulations state that it is perfectly okay to have circulation pumps that are A to G rated, not the A to C rated that had been anticipated. That shows an immediate difference between ambition and practice. I sincerely hope that the Minister of State, Department of Energy and Climate Change, the hon. Member for Bexhill and Battle (Gregory Barker), who has been inviting various other people to come to see him about various issues, will invite me in the very near future to a round-table meeting on circulation pumps and why they should be more energy-efficient. I am sure that he will find time in his busy diary to have a substantial round-table meeting on that pressing issue. I cite that issue as a small example to show that one needs to keep one’s eye closely on the difference between the reality of achievement and the ambition that one has when one puts forward new plans.
The plan that has been the centrepiece of this afternoon’s discussion is the green deal. I feel like someone who is being told that a great new concerto is coming out, that it is about to be performed and that when people turn up to the concert hall they will find that it is terrific, but who has not been told whether it is by Mozart or Salieri. I presume that when we get to the concert hall we will find out whether the green deal is as good as we are led to believe. On the surface, a green deal that takes away the idea of an up-front loan and places the onus on the long-term consequences of the bills of those household consumers, their descendants or the next people who come along to the house appears to represent a positive way forward. We must recognise that that has limitations. Just as the pay-as-you-save scheme implemented by the previous Government had its limitations, this green deal also has potential substantial limitations.
