New Homes (Solar Generation) Bill

Lewis Cocking Excerpts

2nd reading
Friday 17th January 2025 Commons Chamber

[Lewis Cocking (Broxbourne) (Con)]

I congratulate the hon. Member for Cheltenham (Max Wilkinson) on his Bill. I do have some reservations about it, which I will go into shortly, but I am minded to support it today because this is a much better policy than the current Government line about having large-scale solar farms on all our farmland throughout the United Kingdom. I would much rather solar panels were put on new builds, and councils already have some powers enabling them to do that. Broxbourne council, which I used to lead, has engaged in extensive negotiations with developers, particularly at High Leigh, where we have managed to get solar panels on some of the houses. A large data centre is also being built, and we have managed to put some solar panels on that.

As I have said, I do have some concerns. I am all for taking on developers and ensuring that they pay for their section 106 negotiations and do their community work, and standing up for the residents we all represent. However, during many of the negotiations when I led the council, developers told me that they wanted to put solar panels on more houses but the distribution network operator had told them that there was not enough capacity. I said that no one would be able to see the top of the data centre, so why not cover the whole thing in solar panels? Why would anyone not want to do that? Why would anyone not support it? That was my negotiating position. The developers went away and had discussions with the DNO, which said that they could have only 25% because there was not enough capacity for more and the system would not be able to cope. We need to have a discussion about the capacity of the grid if we are going to do this. I know that the Bill focuses specifically on new build properties, but surely it is a good thing to be able to use the rooftops of all the large data centres and warehouses that are already available.

The hon. Gentleman is speaking passionately about his constituency, but does not cheaper battery technology mean that people do not have to sell their electricity back to the grid any more? They can keep it within their boundaries and use it themselves.

[Lewis Cocking]

I was about to mention battery technology, so I ask the hon. Gentleman to wait just a few seconds.

The Bill does go quite far in that its ambition relates to all houses, but I think we should go further. If we are putting solar panels on houses, we should require those houses to have battery storage as well, which might solve some of the problems involving grid connection and there being sufficient capacity. Battery technology is a bit behind solar panel technology in terms of efficiency, and it is not quite there yet on cost-effectiveness, but we are definitely getting there. For example, it is more cost-effective to use the electricity in an electric car than to send it back to the grid. I urge the hon. Member for Cheltenham to consider that, because if we are taking this one step in installing solar panels, perhaps we should take one further step and require people to have battery storage as well.

I am concerned about the red tape we are going to create for new development. As I said, I am all for taking on developers—I see some councillors and former councillors in the Chamber, who have probably all had vociferous discussions like the ones I have had with developers about them doing their bit—but I am concerned about the pushback we might get in discussions on section 106 agreements. There are issues around viability, which I will not go into now, but I would not want to see developers telling their local councils and communities, “We can’t give you money for the new school or the doctor’s surgery because we’ve got to put solar panels on housing.” We need to give some thought to how that will work, because we all want the most community money possible for the roads, schools and GP surgeries that must come with new developments.

There will be some homes for which solar panels are not suitable. I am fully supportive of panels being installed on buildings that have an east-west facing roof, or on a block of flats. Where it is practical to do that, of course we should do it. As other Members have said, it is increasingly frustrating when we drive past a development to see a roof with only two solar panels on it, after the developers have gone through the whole cost of putting up the scaffolding and building the house. I suspect that is because of the issues around capacity, which we definitely need to look into, but come on. If they are already putting solar panels on half the roof, they should fill the whole roof with them, because that does not just help them; if they can sell the green electricity back to the grid, it helps everybody.

I have some reservations about where the money will come from. I would not want it to come from the resources that would have gone on schools, education and roads through section 106 agreements, so we need to look at that. We also need to look at distribution network operators and capacity, to make sure we can really harness the energy, but as this proposal is much better than having large-scale solar farms plastered all over our green belt and the countryside, I am minded to support the Bill’s Second Reading.
