New Homes (Solar Generation) Bill

Chris Hinchliff Excerpts

2nd reading
Friday 17th January 2025 Commons Chamber

[Chris Hinchliff (North East Hertfordshire) (Lab)]

I begin by making a declaration of interest: my former employer, CPRE, the countryside charity, is a supporter of the Bill. Many of my constituents are also passionate supporters of the proposal for mandatory rooftop solar on new buildings; it is one of the issues on which I have had the most correspondence in recent months.

In North East Hertfordshire, the towns of Royston and Buntingford have seen rapid development in recent years, as have smaller villages such as Barkway, Puckeridge and Standon. In the near future, a new estate will be built on the edge of Letchworth Garden City and the town of Baldock is due to roughly double in size. At the same time, we face many challenging decisions locally to balance the need for renewable energy with the protection of our high-quality farmland, while also preserving and enhancing space for nature. It is therefore unsurprising that residents in North East Hertfordshire can see the common sense in making the best possible use of our finite land by putting the solar panels we need on rooftops.

Our approach to delivering the renewable energy we undoubtedly and desperately need has been far too laissez-faire.

[Olly Glover (Didcot and Wantage) (LD)]

My constituency has also seen significant population growth; it has grown by 35% in the past 20 years. New estates in Didcot, Great Western Park, Wantage, Kingsgrove, Highcroft in Wallingford and Wellington Gate in Grove have not all sought the opportunity to have solar panels on the new houses. Does the hon. Gentleman agree that if we do not create the homes of the future now, there is a risk that we will have to retrofit them in future, at great expense, to reach our net zero targets and help residents with their bills?

[Chris Hinchliff]

I wholeheartedly agree.

As I was saying, we could suffer from the potentially profound impacts of competing demands for space for the homes we require, our commitment to protect 30% of our land for nature by 2030, and our fragile food security. Government figures show that with an industry average of 5 acres per megawatt, the proposed ground-mounted solar schemes put forward to date would, if they all went ahead, require a total land area roughly equivalent to Birmingham, Bristol, Manchester, Liverpool, Nottingham, Newcastle and Leeds combined. Yet at the same time, academic analysis indicates that between suitable existing buildings and new construction, there is potential space for 117 GW of rooftop solar in England by 2050.

[Gideon Amos (Taunton and Wellington) (LD)]

Does the hon. Gentleman agree that it was a shocking dereliction of duty when the previous Government cancelled the zero-carbon home programme, which would have allowed for the generation of around 3,000 MW if every house built since 2015 had had solar panels on it? Does he agree with my residents in Taunton and Wellington, who are aghast and want to see solar panels on the new houses being built in Comeytrowe, Staplegrove and Monkton Heathfield?

[Chris Hinchliff]

I find myself, once again, in wholehearted agreement.

Ensuring that solar panels are installed on the rooftops of new buildings specifically could deliver a generating capacity over six times greater than that of Sizewell C. Clearly, if we start applying a strategic approach beginning with the provisions in the Bill, we can host the vast majority of the solar panels we need on our rooftops. Other nations are already proving that this can be done, with similar regulatory measures currently in place in Germany, China and Japan. Better yet, enacting this legislation would not only accelerate our progress toward meeting our climate targets, reducing the industrialisation of our countryside and protecting rural communities; it also offers the most effective way to ensure that the net zero transition lowers electricity bills for consumers.

[Adrian Ramsay (Waveney Valley) (Green)]

I refer to my entry in the Register of Members’ Financial Interests; my former colleagues at the MCS Foundation have provided research in support of the Bill.

I want to pick up on the hon. Gentleman’s point about timescales, because in my experience this issue is the one that is raised most commonly by residents wanting to see action. Why on earth, they say, are new homes being put up without solar panels on them? Time is of the essence, but is it not the case that we have already lost many opportunities to progress? Regulations were due to come into force in 2016 that would have required all new homes to have zero carbon standards. Those regulations were scrapped by the coalition Government. [Hon. Members: “No, they weren’t.”] The briefing I have had says that they were scrapped in 2014. [Interruption.] Either way, I am pleased to see cross-party support today to press ahead with this proposal at speed. Does the hon. Gentleman agree that speed is of the essence here to ensure that homes are not being put up without solar panels?

[Chris Hinchliff]

I agree that speed is of the essence in multiple ways, and I encourage the Government to move as quickly as possible.

Empowering households to generate the electricity that they use will help families to lower their bills far more rapidly than commercial schemes that feed into wholesale energy markets influenced by international commodity prices. This strikes me as a well-drafted Bill, and I congratulate the hon. Member for Cheltenham (Max Wilkinson) on its clarity and flexibility. The only thing that I might suggest is a widening of the provisions to cover commercial buildings as well, given the vast opportunities provided by warehousing space. It is estimated that we currently use only about 5% of warehouse rooftops for solar generation. Claims that the regulations would hinder innovation are clearly spurious, especially in view of the provisions for exemptions where other forms of renewable energy generation are installed.

It is high time that our country had common-sense standards for rooftop solar on new builds, and I hope that the whole House will support the Bill.
