To ask His Majesty’s Government what recent assessment they have made of the impact of current levels of home insulation on health and mortality rates.
My Lords, evidence of the health benefits of government insulation schemes is gathered as part of those schemes’ evaluations. Recent evaluations show that schemes had a positive impact on general health. For example, improvements in the health of someone in the household were reported after the installations from our government energy efficiency schemes. Of course, the health impacts are higher for those with pre-existing health conditions.
Recent reports, including by Sir Michael Marmot, have made a clear link between poor home insulation—coupled with the cost of living crisis and high energy costs—and devastating impacts on the health outcomes of thousands of the most vulnerable people across the country, young and old. What cross-cutting analysis are the Government undertaking to reassess fully the impact of their performance in delivering home insulation in the light of the chronic health outcomes highlighted?
I just explained in the Answer to the noble Baroness that as part of all our energy efficiency schemes, we do evaluations afterwards of the effect on people’s bills and health. We are spending over £12 billion over this Parliament and the next on insulation schemes, because we know they make a crucial difference.
My Lords, it feels as if energy conservation is still the last thought and never the first. We have some of the highest domestic energy bills in Europe and some of the worst-insulated homes, yet we fail adequately to improve home insulation. Meanwhile, we continue to import gas from countries such as Russia. When will the Government do the right thing for bill payers and the environment and set more ambitious home installation targets, particularly for social rented homes?
I disagree with the noble Earl; the figures he quoted are not correct, and we are improving home insulation standards. To give one figure, in 2010, 17% of homes in the UK were EPCC or above; now the figure is almost 50%, so we are making progress. We have a lot more to do. We have the oldest housing stock in Europe, but we are making progress.
My Lords, have the Government given any thought to older houses, particularly ones in conservation areas or that are listed? If you want to replace sash windows with double-glazed ones, there is not only that expense but the need to obtain planning consent or listed building consent. It is a very expensive enterprise. What do the Government propose to do to help in this situation?
The noble Baroness makes a very good point, and I suspect that she speaks from personal experience. Improvements in energy conservation for homes in listed or conservation areas is a difficult issue. We recently carried out a joint study with DLUHC and Historic Houses, and provided guidance for home owners wanting to do that. She will be delighted to know that you can get well-insulated, double-glazed sash windows to replace the originals.
My Lords, those with respiratory conditions face life-limiting risks from fuel poverty and poor insulation, and those risks are obviously triggered by weather factors. Is the Minister aware of the potential of AI-based weather models to predict and manage the risks faced by those with health conditions, including prioritising those who would benefit most from the insulation programmes? Will he engage with partners such as the Alan Turing Institute and the Met Office to explore the opportunities to harness these technologies for public benefit?
I thank my noble friend for the question. There are some great technologies coming forward now and, of course, we are always interested to explore how government investment can be better targeted on those who need it the most.
My Lords, is the Minister aware that there are problems with cavity wall insulation in various older houses, in that the cavities are not large enough to qualify for government assistance? Will he look into that and see if anything can be done to move it forward?
I am certainly aware of some technical challenges with different technologies. We have a multiplicity of different housing types. Of course, if the cavities are too small, those properties can benefit from internal or external wall insulation. I would be happy to have a look at that for the noble Lord.
My Lords, has any thought been given to our mortgage providers—banks and others—enabling people who move home to get their home insulated by providing a slightly lower interest rate or some other benefit? That would mean that, every time anyone moves, the house would be insulated, for the betterment of all.
My noble friend asks a really good question. We have a number of innovative pilots with lenders, such as green mortgages and different ways of structuring finance that can help people to upgrade their homes. There are some potential tax changes —which, of course, are a matter for the Chancellor—that could help, but we will continue to make the case.
My Lords, I declare my interests as set out in the register. The Minister referred to the amount of money being put into insulation schemes, but does he accept that over the last 10 years a rota of schemes has been introduced, and that they have failed and been closed down? Does he accept that the industry needs consistent, clear policy, so that it can invest in training in particular, so that the money the Government put in is actually value for money?
No, I do not accept that. There has not been a rota of schemes. The most successful scheme, the ECO scheme, has been going since the early part of the previous decade and we have committed funding for a number of years to come. The more successful schemes, such as the social housing decarbonisation fund and others, are also multi-year programmes precisely to provide the long-term certainty to industry that so many contractors say they desire. We have already announced the funding for 2025-28—another £6 billion—and we have set out the schemes on which it will be spent. So, no, I am afraid I do not accept the noble Baroness’s analysis.
