New Homes (Solar Generation) Bill

Pippa Heylings Excerpts

2nd reading
Friday 17th January 2025 Commons Chamber

[Sir Roger Gale]

If the hon. Gentleman can tell me of a photovoltaic tile that is acceptable to the people who are enforcing regulations relating to listed buildings, I would be delighted to hear it. That is what I was trying to come on to before I was interrupted.

Kent, a wonderful county, has very many grade II listed buildings, and at present, it is not permitted to use solar panels—or solar tiles, as I would like to see them—on those listed buildings. It is not even permitted on other buildings, outbuildings, cottages or whatever within the curtilage of a listed building. That rules out a considerable quantity of property that can and should accommodate solar panels.

[Pippa Heylings (South Cambridgeshire) (LD)]

King’s College in Cambridge, one of the oldest and most prestigious heritage buildings, now has a fine array of solar panels that it managed to get through planning permission. Does the right hon. Member agree that what we need in planning terms is for material weight to be given to climate change, as well as conservation status? That is where the crux of the matter is. It would allow all those who are responsible for listed homes or who have homes in conservation areas to do energy efficiency in the right way.

[Sir Roger Gale]

Up to a point, I agree with the hon. Lady, but only up to a point. I do not want to see the fine buildings of Kent smothered in hideous installations, so we have to find a way technically of making the panels acceptable. I accept entirely that retrofitting is much harder than new build. It is possible to inset photovoltaic panels into a new roof on a new build, but it is much harder to retrofit it attractively. I would like to see us make much more effort to go down that road, so that we come up with products that are acceptable across the board—not just for new build, but for existing buildings.

It is essential that this Bill has a Second Reading, and I will be supporting it today. There are flaws in it, but that is what the Committee stage is about, and we should allow the Bill to go into Committee. If I may say to the hon. Member for Cheltenham, there is rather too much wriggle room. I can see canny developers finding ways of exploiting some of the exemptions, if we are not careful, that he has written into the Bill.

[Pippa Heylings (South Cambridgeshire) (LD)]

As the Liberal Democrat spokesperson for energy security and net zero, I am delighted to support the private Member’s Bill of my hon. Friend the Member for Cheltenham (Max Wilkinson): the sunshine Bill. Madam Deputy Speaker, I am beaming.

South Cambridgeshire is one of the fastest growing constituencies in the country in terms of house building and lab space. People constantly say to me, “Why are all of these new homes without solar panels on their roofs?” or “Why do these new homes only have one or two solar panels or only on part of the roofs?” Sadly, in 2025, developers are still required only to meet—not exceed—the Merton rule’s inadequate 10% energy improvement standard. That is why Liberal Democrat councillors in my constituency have been pushing hard to change this at the local level. In fact, in the five years since they took control of the council, South Cambridgeshire has rapidly become the district with the highest number of solar panels fitted and with the fastest increase in planning applications that include solar panels.

It is the lack of ambition and political will at the national level that has held back the revolution in solar rooftops. That is why we are still building homes that are cold and damp and that have skyrocketing energy bills. The former Conservative Government disgracefully scrapped the zero carbon homes policy, and dithered and delayed on the future homes standard.

[Cameron Thomas]

Earlier, the hon. Member for Waveney Valley (Adrian Ramsay) lamented—in good faith—the drawdown of environmental pledges in 2016. Of course, that was not the coalition Government; what we saw and what we got is what happens when the Liberal Democrats are no longer there to hold people to account.

[Pippa Heylings]

It will not surprise anyone to hear that I agree wholeheartedly. The record has been corrected. It is vital that the Bill helps to repair that damage, and we look forward to the Minister’s commitment to bringing about these changes.

As has been mentioned, the lack of ambition on the solar rooftop revolution has contributed to the barrier to public acceptance of larger scale solar farms. We are hearing people say, “Why not put panels on the rooftops of homes, industrial sites and commercial warehouses first?” We need a joined-up plan; we need the Government urgently to bring forward the much-promised land use framework and the National Energy System Operator’s strategic spatial energy plan, which will show how much solar farm energy is still needed and where it would be best placed. In that way, we can meet all our needs.

The Bill is our chance to get this right. It is our chance for a cleaner, greener and more secure future that addresses the triple cost of living, housing and climate crises and takes people with us. I congratulate my hon. Friend the Member for Cheltenham.
