Rooftop Solar Panels

10. What steps he is taking to increase the use of solar panels on building roofs; and if he will make a statement.

The Government are supporting the installation of rooftop solar in numerous different ways: financial incentives, performance standards and the solar taskforce.

For years now, I have been trying to persuade Governments of all colours to change building regulations to require all new buildings to be fitted with solar panels. That would have the benefit of securing supply, reducing household bills considerably and helping us towards net zero, so why do we not do it?

I assure my hon. Friend that I am a great enthusiast for solar panels—I have had them on my home for the past 12 years, and they perform very well. I want to see more people do that. In fact, over that period, we have gone from virtually no renewables in our system—6.9%—to 43% in the last quarter. I am very keen for that expansion to go further and faster. We need to ensure that it is part of the building code, but we also want to make sure that other forms of renewables can be installed, so it is a balance between not being too prescriptive and making sure that we make speedy progress, particularly on all the commercial rooftops in this country.

A few weeks ago, I had the pleasure of visiting an innovative housing project in Rumney in my constituency, which had solar panels in nearly all the new buildings but also ground source heat pumps, electric vehicle charging points and battery technology in the houses, bringing down bills for the residents while contributing to net zero. Will the Secretary of State join me in praising Cardiff’s Labour council and the Welsh Labour Government for the work they have done on this issue, and will he explain what we are doing to ensure greater manufacture of those technologies in this country?

Of course, I am delighted that the Barnett formula stretches so far in providing some of the excellent additions to those buildings. I just want to repeat that no Government have gone further and faster in the G7 than this one in introducing renewables and ensuring that they now power a very significant part of our grid. We want to go further and faster still, and we will make sure that things such as building codes help with that plan.
