New Homes (Solar Generation) Bill

Debate between Olly Glover and Chris Hinchliff

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.
