[Lord Randall of Uxbridge]

212: After Clause 106, insert the following new Clause—
“Building regulations: swift bricks(1) The Secretary of State must, within six months of the day on which this Act is passed, introduce regulations under section 1 of the Building Act 1984 (power to make building regulations) to make provision for the installation of an average of one swift brick per dwelling or unit greater than 5 metres in height.(2) Regulations must require the installation of swift bricks in line with best practice guidance, except where such installation is not practicable or appropriate.(3) For the purposes of this section—“swift brick” means an integral nest box integrated into the wall of a building suitable for the nesting of the common swift and other cavity nesting species;“best practice guidance” means the British Standard BS 42021:2022.”Member’s explanatory statement
This new clause would require the Secretary of State to introduce regulations to require the installation of integral bird nest boxes and swift boxes in developments greater than 5 metres in height. Swift bricks provide nesting habitat for all bird species reliant on cavity nesting habitat in buildings to breed.

[Lord Randall of Uxbridge (Con)]

In the absence of my noble friend Lord Goldsmith, I shall move Amendment 212, to which I have added my name. My noble friend sends his apologies to the Committee that he is detained elsewhere and cannot be here today. I am grateful, as is he, that my noble friends Lady Coffey and Lord Hintze have also added their names to the amendment.

At the beginning of our deliberations today, the Government Whip exhorted that we have swift debates, and I have moved a swift amendment. So, I am helping the Government yet again.

This is a subject we discussed in the levelling-up Bill and it was mentioned at Second Reading of this Bill. It is a simple amendment, which is probably why I am able to speak to it. It asks that a swift brick, which allows a swift potentially to breed in it, be added when a new build is made. This would apply only when appropriate. I point that out because some people have said that it may not always be appropriate.

I am sure that Members of this House know all about swifts, but here is a very brief résumé. They are migrants that come here quite late—normally at the end of April or in May—having flown all the way from sub-Saharan Africa or the Congo Basin. They do not stop flying. They mate on the wing. The only time they are not flying is when they are nesting.

These poor swifts have been declining in numbers. There may be a variety of reasons, such as a lack of insects and so forth, but one reason that has been identified is the success of insulation in houses. Cavity insulation means that the nesting areas that would normally be under eaves or wherever are not there. Imagine these poor swifts: they have flown all the way from the Congo, they are looking forward to going into the building that generations of swifts have been going to and they find that it is effectively blocked up.

The simple thing we are asking for is that the swift brick is placed in building regulations. I have a feeling that the Government might suggest that this could be planning policy, but I do not think that that is sufficient. I cannot understand why Governments—the previous Government were a little shy on this as well—will not accept this. I know that some people think it is perhaps overregulation or burdensome, and I heard it whispered, but I could not believe it is true, that there is lobbying from developers and builders. I cannot believe that that could in any way influence a Government, so I just ask the Government to reconsider.

This is in fact a great opportunity because, literally just a year ago, I think by a few days, campaigners, including my noble friend Lord Goldsmith, the swift campaigner the indefatigable Hannah Bourne-Taylor and others—I will not mention them all—met the then Secretary of State in Defra, the right honourable Steve Reed. He said that they were pushing at an open door because Defra has always been in favour—they are the friends of the environment—but sometimes other departments get in the way. This is therefore a great opportunity because we now have a convert to swift bricks in the ideal position to sanction this particular thing, so I am hoping that it can be done. It has been done successfully elsewhere, such as in Gibraltar. Some people might ask what happens if swifts do not come in. Other birds, including house sparrows, which are not as common as they used to be, can also utilise them, so it as a very good measure.

I say, finally, to the Government Benches that some of the measures in this Bill have not been quite to the flavour of environmental groups and members of the public who think that their language on bats and newts was a little bit extreme. So, in that same spirit of helping the Government regardless of the political party and in order to help them to get a win-win, this is the ideal time to allow this measure and put it into the Bill.

I support the other amendments in this group: Amendments 225—to which I have added my name—227GA and 338. I wanted to make sure that this is a swift debate. I beg to move.

[Baroness Freeman of Steventon (CB)]

My Lords, I also support all the amendments in this group, which I think would support the Government’s stated aim to help nature in this Bill by making sure that the places that we build for humans at least minimise harm to wildlife and, in the case of swift bricks, actually help it.

I speak to Amendment 225 in my name and thank the noble Lords who have also put their names to it and support it. This amendment would require the Secretary of State to publish guidance on bird-safe design of buildings and to ensure that new buildings and significant changes to existing but not exempted heritage buildings incorporate this guidance as far as is practicable. Incorporating this amendment would not only bring the United Kingdom into alignment with what is seen in other jurisdictions around the world but would make the UK the first to introduce national bird safety legislation, which is something that could provide a welcome positive message for the Government to project.

I know that there are broader environmental concerns with the Bill, which we shall come on to later tonight, but the potential positive effects of this single amendment are enormous. Remember that the number of birds thought to be killed by flying into glass in buildings in the UK is over 30 million per year. The problems are simple. First, birds cannot see glass. Clear glass or glass that is reflecting nearby trees or sky is a hazard. Secondly, at night, artificial lighting, particularly in tall buildings, can disorientate migrating birds, making them end up circling the lights until they are exhausted and crash into a building.

The solutions are also simple, well researched and legislated for in many places. I have been able to base the wording of this amendment on that in many other jurisdictions, such as San Francisco, which has mandated bird-safe standards since 2011, Washington DC, New York, Portland in Oregon, Toronto, Calgary, Hesse and Zurich. There are also bird-safe design guides based on 40 years’ worth of research that can provide an easy reference from the United States, Canada and Singapore. We have experts in the UK too. They all agree on some simple features of buildings to avoid—essentially, ones that make it look as though a bird can fly through safely to reach sky or a perch in a tree, but where there is actually a sheet of lethal glass. These can be removed through thoughtful architectural design, or you can use bird-safe glass. That is simply glass that is made visible to birds, either through patterns that we can also see or through patterns that reflect ultraviolet, which are invisible to us but visible to birds.

Research has shown that specific patterns, such as lines no thinner than two millimetres, spaced no wider than 50 millimetres apart, can effectively stop a bird flying into glass—a more than 90% reduction in collisions in tests. These test centres can therefore certify bird-safe glass, and there are many designs available from different manufacturers, including the UK’s Pilkington glass, which has a certified variety.

Then there is night-time lighting. Many cities around the world now have lights-out times. Even New York’s Twin Towers memorial beams get switched off for periods during bird migrations to help birds escape their fatal attraction. In the UK, awareness of this problem and its simple solutions is surprisingly low compared to North America. Experts I have spoken to around the world were delighted to hear from me, because they think of Britain as being so far behind in bird-safe buildings despite a world-leading status in so much animal welfare research and legislation. This amendment could put us back as global leaders in having the first national bird safety legislation, it would help put the Bill in line with the Animal Welfare (Sentience) Act 2022, as the Animal Sentience Committee has already pointed out, and it could save tens of millions of birds every year.

As for the cost, producing guidelines is easy, as I say, given the plethora of sources already available. Bird-safe architectural design is also easy once you know the guidelines. In a double win, many of the coatings and shades that help make glass less dangerous to birds also help with thermal issues and energy efficiency in glass buildings. The regulations on night-time lighting could help energy efficiency too. The cost of glass varies depending on specifications, but manufacturers that I have spoken to estimate that, at the moment, the cost of bird-safe glass in commercial buildings is about 5% more than normal glass and about 10% more for a domestic glazing unit, but all have said that those costs would come down quickly with scale. Not only that, but bird-safe glass apparently used to be made here in the UK, with 90% of it exported to projects in China, Europe and North America, driven by their legislation. With the market mainly being overseas, manufacturers have now mostly moved from the UK to Germany to follow demand, but could return if we caught up with global bird-safe legislation.

Amendment 225 seems to me an example of the much sought after win-win. Putting it into this Bill, alongside others in this group, would help demonstrate the Government’s stated commitment to helping nature and nature recovery, alongside helping British businesses and not slowing down any housebuilding. I very much hope that the Minister will agree.

--- Later in debate ---

Therefore, while I thank noble Lords for their amendments, there is existing legislation in place to protect vulnerable species and that, combined with the measures in the National Planning Policy Framework, means that we remain of the view that planning policy is the best mechanism to ensure that development proposals consider wildlife. Therefore, I kindly ask the noble Lord to withdraw his amendment.

[Lord Randall of Uxbridge (Con)]

My Lords, I was a bit remiss in not congratulating the Minister on remaining in post. Prime Ministers make, from time to time, crazy decisions—I have seen it happen—but nothing would have been crazier than to remove the noble Baroness from her position. That is why I did not even think about it.

I thank all noble Lords who have taken part in this very interesting debate. It is a subject that I care very passionately about. I agree with my noble friends Lord Caithness and Lord Lucas, but I am testing the Government to see whether they can get one tiny thing through. I think the answer is no—not yet anyway.

Bird-friendly buildings is a really important subject. It does not have to mean that you switch the lights off all the time, it is about reflections and so forth. We may return to this.

My noble friend Lord Blencathra might speculate about where my noble friend Lord Goldsmith is, but I could not possibly comment.

I say to the Minister: in the same way as the swifts return every year, albeit in smaller numbers, this too will return on Report, albeit with greater numbers and more vehemence. In the meantime, I beg leave to withdraw the amendment.

Amendment 212 withdrawn.
