Levelling-up and Regeneration Bill

Debate between Lord Goldsmith of Richmond Park and Lord Evans of Rainow

Report stage
Wednesday 6th September 2023 Lords Chamber

[Lord Goldsmith of Richmond Park (Con)]

My Lords, before making a point about the amendment, I acknowledge that my noble friend on the Front Bench rightly feels a little blindsided by it. I apologise to her for that. I am a newbie on the Back Benches and I clearly have much to learn about the process here. In my defence, I shared my plans and the wording of the amendment with my friend the Secretary of State who, I am pleased to say, was excited by much of the contents, although not all of it.

I will be brief because this proposal is relatively simple and, in many respects, speaks for itself. Before I describe it, I will heap praise and thanks on a campaigner who is simply formidable. I am pleased that she is in the Gallery today, probably holding a swift box. Hannah Bourne-Taylor has single-handedly made what for many people appears to be a niche concern into a national campaign—not least by walking naked through London painted as a swift and causing quite a stir, as noble Lords can imagine. She has turned this into a national cause. It is because of her that this amendment exists.

Back in 2002 the British Trust for Ornithology cited the loss of cavity nesting sites as the key factor in the decline of cavity-nesting urban birds. Since then, four species—house martins, starlings, swifts and house sparrows—have been added to the dreaded red list of species of particular concern that, crudely speaking, face extinction. Worst hit among them are house martins. When I was preparing my notes, I was going to say that there has been a 37% decline, but I have since discovered that the figure is even worse at 50%. Swifts too have suffered horrifically; their breeding population declined by 60% between 1995 and 2020. That number continues to sink.

Despite broad agreement, not just in this place or the other place but across the whole country, that the UK—one of the most nature-depleted countries on the planet—requires urgent action or to introduce emergency measures to turn around these trends, the reality is that nothing of any real substance has yet been done. The problem, as noble Lords no doubt know well, is that sites for cavity-nesting creatures such as swifts have simply been lost. It is not because of evil or malign intent but because of repairs, house modernisation and even insulation—something of which we all in this House would like to see much more.

This simple proposal to include swift bricks in new builds is key. It is not just about providing a supporting hand to a species in trouble; it is critical, indeed essential. Modern new-build homes are simply not designed to accommodate nature. Swifts in particular rely completely on cavities, as noble Lords know. Without those, there are no safe or permanent nesting sites for them in Britain. Without manmade cavities in this sense, those birds have no future in this country. It is crazy, and something I learned only recently, that the simple swift brick is not even included in the biodiversity net gains metric.

The amendment that we are here to discuss today could not be much simpler. The swift brick is a zero-maintenance solution. It is just a brick in a wall that can be added to a building as any other brick could. For a refurb or a new build, it is cheap; it costs £30 or thereabouts. We know that they work because, wherever they have been tried and installed, they have worked. Surveys conducted on, for example, the Duchy estates, where swift bricks have been installed in numerous buildings, have resulted in a staggering 96% occupancy rate. Even that number continues to grow.

Obviously, not all the bricks are used by swifts. I have heard that as one of the counterarguments—“What about other creatures using these boxes?”—to which my answer is, “So what?”. Heaven forbid that a house sparrow might decide to use one of these swift boxes. Who would not be filled with joy at the prospect? It just seems to me to be such a non-argument as to almost not merit discussion.

If this amendment is adopted—I really beseech colleagues to support it—and it becomes national policy to ensure installation of these magical, simple, cheap bricks in all new homes, it will not only help counter the tragic loss of cavity-nesting birds but directly help the Government themselves meet what are, let us remember, legally binding targets to halt biodiversity loss by 2030. This measure has unanimous support—not all measures do—from ornithologists, all of whom agree and have gone to great lengths to explain that there is no downside.

By the way, swifts do not eat vegetation; they eat insects. They particularly enjoy mosquitoes and eat mountainous volumes of them, so there is yet another bonus to encouraging swifts in and around our homes. I am told that they also do not leave droppings; there is a reason for that, which I will not go into. I am sure that the expert up in the Gallery will know, but they do not leave droppings underneath their nest boxes. They tidy up—I will tell noble Lords what they do; they eat them, I am afraid, probably to recycle the mineral content. I do not know why, but for whatever reason they remove them. They are very tidy, conscientious and thoughtful creatures.

This amendment is also flexible for developers. Those I have heard from are all supportive. One major housebuilder, Thakeham, has actively appealed for an industry-wide commitment. Very recently the Irish Citizens’ Assembly on Biodiversity Loss voted to include swift bricks in all new builds. In the Netherlands, swift bricks are already installed as a mitigation measure.

There have been suggestions, and I understand where they have come from, that this should be a voluntary measure. I get that; no one wants excessive bureaucracy and mandates. But I am afraid we know that this has not worked. It is not through lack of caring: who does not want to see swifts flying in and around—maybe not in—their homes and gardens? Who does not feel better, frankly, when they have greater proximity to nature?

In fact, a petition that was initiated by Hannah in the Gallery attracted 110,000 signatures—

[Lord Evans of Rainow (Con)]

My Lords, noble Lords should not refer to people in the Gallery.

[Lord Goldsmith of Richmond Park (Con)]

As I said, I am a newbie on the Back Benches and that is yet another rule I have learned. I will cease referring to the person in the Gallery. But 110,000 signatures were collected by the person in the Gallery. I think that is pretty impressive, given the subject matter we are talking about.

National legislation is necessary because of the urgency of the situation. We have debated the issue over and over again; we understand that this country is in the midst of a biodiversity collapse. National legislation is necessary because nowhere near enough swift boxes have been installed, despite swift bricks being nationally promoted since 2019, including in guidance in the National Planning Policy Framework. That is not to diss the NPPF; it is a valuable piece of literature, but it has been largely ignored in the context of the issue we are discussing here today. A paltry 20,000 boxes have been installed at best—that is an optimistic assessment. District councillors and the vice-chair of the Association of Local Government Ecologists have all been clear that the current situation is not enough. We are simply not seeing take-up of these swift boxes. Of 455 local planning authorities in England, just nine have planning conditions around swift boxes, so the voluntary approach does not work.

We are asking here for something so small, so simple and so inexpensive, but something that will have a gigantic impact on these irreplaceable, iconic creatures. I really encourage the Government to think again about their opposition to a measure that is wildly popular and would do so much good for this country.
