My Lords, since it is a long time since I last contributed in this Committee, I start by declaring my interest as co-chair of Peers for the Planet. Amendment 478 has cross-party support, and I am grateful to all noble Lords who signed it. Alongside Amendment 504GJE, in the name of the noble Lord, Lord Lucas, the amendment recognises the enormous potential of maximising the UK’s solar capacity, not only in terms of energy production but also in terms of that levelling-up agenda to which we have devoted so many hours in Committee.
The amendment would require the Secretary of State to make building regulations requiring all new homes and buildings in England to be built with solar panels from 1 April 2025. It is a simple but sensible and important amendment, which recognises the need for flexibility for different types of building—not every one will be suitable—and gives appropriate exemptions. It could be aligned with the introduction of the future homes standard in 2025. As I said, rooftop solar on buildings can bring many benefits, including reducing bills, enhancing energy security, bringing jobs and skills across the whole country and decarbonising our homes.
I recognise that the Government have made welcome progress on solar since I first tabled this amendment through the commitments they made in their recent Powering Up Britain package, which adopted many of the Skidmore review recommendations. In their new energy security plan, the Government recognise the importance of solar deployment—both rooftop and ground—in decarbonising the power sector. But, as so often with government strategy in these areas of net zero and the environment, the Government use more nouns and more adjectives than verbs. This amendment tries to put some action immediately into the area of solar power. For a true rooftop revolution, much more action is needed.
Analysis by the trade body Solar Energy UK found that further efforts than those outlined in the Powering Up Britain package will be needed to secure the Government’s ambition of 70 gigawatts of solar by 2035. The recent BEIS Committee report also called for more action, recommending that the UK
“ramp up the pace at which new solar capacity is deployed”.
Regulating for rooftop solar on all new buildings is a specific, simple, straightforward action which the Government could take now. As highlighted in the Skidmore Mission Zero report, there is currently no target to make rooftop solar a standard for buildings across the UK.
I hope we have learned some of the lessons of the past when we allowed buildings to be constructed which we knew at the time would not meet the energy needs of the future. In fact, sometimes we got the regulations right once and then reneged on them and went backwards. We have ended up with buildings that are inappropriate and have to be retrofitted, which is more expensive and less effective. This is a real opportunity not to make that mistake again.
Solar for all new homes and buildings is backed by the public, by industry and by the experts. It makes financial sense and, as I say, it is much cheaper than retrofitting in years to come. Other countries have understood this and are making provision for rooftop solar on commercial and residential properties. In March, the EU agreed revisions to the energy performance of buildings directive, which will require all member states to ensure that new buildings are equipped with solar technologies where technically suitable and economically feasible—exactly what I am trying to achieve in this amendment.
The recent letter to the Government from the Environmental Audit Committee urged them to urgently address key barriers to solar deployment across the planning process, which is another debate we have had on the Bill. The committee highlighted evidence of a tendency among developers to just fit the minimum that they need, and the fact that housebuilders will build to the regulations—so we need to change the regulations. It recommended that
“the Future Homes Standard incorporate installation of solar PV … as a minimum requirement for newly constructed housing”.
That is precisely what my amendment is asking for, and it would support the government policy and ambition to increase from 14.5 gigawatts of solar now to 70 gigawatts. On that basis, I beg to move.
