New Housing: Swift Bricks

Siobhan Baillie Excerpts

That is a very good point, and it is one that Guy Anderson, from the RSPB’s migrant recovery programme, has made in response to the Government. He has said that he cannot see any reason why swift bricks would be inappropriate in any development in the UK. He says:

“there may be some buildings where the design...makes it...less likely...to ever be used by swifts...however, even if...not used by swifts...red-listed house sparrows, red-listed starlings or red-listed house martins may use them”.

I would therefore urge the Government to look again at the policy and at what can be done to either enforce or encourage the delivery of more swift bricks in homes across the country.

To end on a brighter note, there are now many examples of swift bricks being used. One of the largest installations of swift bricks has taken place across the Duchy of Cornwall estate. The “Big Duchy Bird Box Survey” showed that, across all of the newly installed swift bricks from 2015 onwards, almost half had been used.

I want to give credit to the RSPB for this campaign, but also to the Stroud Valleys Project, which has been a really strong campaigner on this. It does things such as a “Swift Walk” around Minchinhampton common, which is absolutely fantastic. I wholly endorse the proposals for changes in terms of local authorities and planning, but what I want to hear from my hon. Friend is a real gee-up for everybody who is promoting the protection of these species, because there is actually a lot going on in many of our communities. I am not down on the swift boxes, by the way; while homeowners do not necessarily have the bricks, they can look to have the boxes. I think that this is a wonderful opportunity to celebrate these birds.

[Matt Vickers]

One thing to say about this petition is that, while there are lots of petitions that people sign because it is in their own interests, for the 109,000 people who signed this petition, this was not necessarily in their personal interests but was something that they saw as being in our natural interest and as a huge game changer for the country.

We can combine that result from the “Big Duchy Bird Box Survey” with other large-scale installations that have taken place. Barratt Homes is leading the way and doing its bit, going above and beyond. It has installed boxes on a huge number of sites, and it reckons that as many as 96% are being used, with that percentage increasing over time.

There is plenty of climate anxiety to go round at the moment. Unlike Hannah, I am not going to take my clothes off, and nor am I going to go round chucking orange powder and confetti everywhere, but I will leave Members with this thought. In a survey carried out by Lancet Planetary Health into climate anxiety among children and young people, around 60% of those young people said they feel extremely worried about climate change and our natural environment. This proposal is an opportunity to help to save four species at minimal cost and inconvenience. It is welcomed by the public and by developers, and it is time to get on with it before it is too late.

It certainly does. I was going to mention Hertford and Halesworth, and now I can say Hampshire too. Cambridge also has a group.

I pay particular tribute to Save Wolverton’s Swifts and Martins, which has a special place in my heart because it is run by my sister, who is in the Public Gallery. That shows the difference between us: I am always here talking about things, and she is actually out there doing things. That group has provided 170 new homes for swifts since 2020, and this year swifts have finally taken up home in her house.

Last year, because the heatwave made the bricks too hot, there was a real problem with fledglings trying to leave before they were ready to fly. All around the country, local groups rescued swifts; my sister cared for 17. I remember going down to Sidcup to pick up her daughter from university, and as the three of us sat outdoors at a Sri Lankan restaurant, there was a swift on the other chair being fed crickets—it had to be fed every hour to keep it alive. My sister did that while juggling three kids and working a full-time job.

An interesting fact is that a swift weighs the same as a Cadbury’s creme egg. Save Wolverton’s Swifts and Martins is making egg cosies to raise funds for swift groups. If anyone wants one, I am sure I can arrange that.

I also want to thank Milton Keynes Swifts, which works very closely with Save Wolverton’s Swifts and Martins. I thank Mike LeRoy for sending me a comprehensive briefing about the work that group is doing with developers and housing associations. It was particularly helpful on biodiversity net gain, which I will come to in a moment.

As we have heard, when a building is demolished or renovated, swifts lose their nests, and new buildings do not always offer the same nooks and crannies. That habitat loss is one of the reasons swifts are now red listed. They are a conservation concern, as their numbers fell by 62% between 1995 and 2021.

Other Members have explained effectively that swift bricks are very simple and easy to use. They blend into the building and do not affect insulation. That issue has been raised with me, particularly given the discussion at the moment about the need to retrofit homes, but the bricks will not have an impact on the energy efficiency programme. They are durable, low cost and do not require maintenance. Even if they do not attract swifts, they can be beneficial for other red-listed species such as house sparrows, starlings and house martins. Hibernating tortoiseshell butterflies and bees also use them.

[Siobhan Baillie]

I defer to the hon. Lady’s absolutely fantastic knowledge of swifts, and I thank the former aviation Minister, my hon. Friend the Member for Witney (Robert Courts), for his amazing account of swifts’ aviation.

Swift bricks have been around for many years—possibly 20 years. They are very simple and cheap to install. There is deep affection for these birds, not least in Stroud. I thank the 500 petitioners from Stroud and the thousands of others. Does the hon. Lady agree that we have waited long enough, so we need to mandate? The bricks are so simple, and it is obvious that we need to install them, but that is not happening at a great enough scale, so mandating will make the difference for that species.

[Kerry McCarthy]

As has already been said, only a small number of local authorities—Exeter, Hackney, Islington and Brighton and Hove—have taken the step of requiring bricks. I am working on Bristol, and I hope we will do that in the next iteration of its local plan. That is tiny compared with the potential of what we can do. It would be so easy to have swift bricks in all new developments—not just new housing, although the petition is about housing, but other buildings too. We need to do something to turn this from a nice little local initiative into something that is far more widespread.

It is important to say that developers are not opposed to this proposal. Barratt Homes has actively worked with the RSPB to develop a swift brick and has pledged to install swift bricks in all new houses built in Bristol as well as in several other cities. I actually went up on the roof of one of its new houses in Blackberry Hill—one of those classic “MP in a hard hat”-type pictures—to do that. Another sister of mine is working with a housing developer in Milton Keynes that is also putting swift bricks into all of its new houses. This work can be done and there is no opposition to it, so there is no reason for the Government to be cautious about it.
