I think the way social media presents conversations like this doesn't help. If this was a face to face discussion it wouldn't end up as an argument.
However, think about it this way. Hertfordshire has around 5000 houses built each year. Is 357 Swift bricks over the last 5 years really enough?

My first comment was in relation to voluntary installation, which is extremely limited. In my experience, developers will do the bare minimum or forget to install at all
If the Homes for Nature commitment is honoured, then it will be excellent news, but experience so far suggests that it won't be

Here is evidence from Hertfordshire as to compliance with planning conditions for Swift bricks. 106 developments visited and less than half of the required bricks installed.
We have no voluntary installations in the county

See my other post. There are 8 bird boxes on a large development, only some of which are Swift bricks. This is almost certainly doing the minimum to comply with a planning requirement

I am not saying there are not Swift bricks, there are, but the vast majority are as a result of planning requirements.
David Wilson are part of Barratt who have installed bricks voluntarily
Read the High Weald post again. It is about how few Swift bricks there are on a large development

Cala Homes have had a commitment to 1 Swift brick per dwelling since 2022. I am unable to find details of any development where they have actually done this.
In Hertfordshire, Cala have installed 1 Swift brick in the last 3 years, and that was incorrectly installed as an external box

Barratt and the Duchy of Cornwall Estate have voluntarily installed them, no others have.
As I have already pointed out, the Hones for Nature commitment started from September 2024. No houses have yet been built in relation to that scheme

I frequently visit building sites to check that Swift bricks have been installed, and at the majority they haven't. When talking to site managers, I regularly get the impression that they have no idea what I am talking about

It is too early to say that. The Homes for Nature commitment that developers have signed up to only applies to planning applications submitted from September 2024, and none of those have been built yet. I doubt that many even have planning permission after a year.

The Duchy survey also found that House Sparrows did not use integrated Sparrow boxes, preferring Swift bricks wherever installed

Swifts are normally the slowest to occupy, however in 2025 they started using the Swift bricks at two of the Duchy sites in small numbers, and this will grow in future years.
I don't understand your point. Universal Swift bricks are used by 4 red-listed species. Why would you install any others?

You have this wrong. Vast majority of houses are suitable. British Standard, BS42021:2022 makes Swift bricks suitable for a variety of small birds as per @hannahbournetaylor.bsky.social above. The evidence from the Duchy Bird Box project backs this up

Could you remind @hertsmerebc.bsky.social and @stalbanscouncil.bsky.social about this please? We comment on planning applications throughout Hertfordshire but these two councils still do not condition Swift bricks on new developments

Kevin, absolutely agree. Very interesting paper which I hadn't read before. Lots to digest in there.
I do have to try and find hope for Swifts when I can. Without it I don't think I could continue Swift conservation work

A good example is the famous colony in the tower at the Oxford Natural History Museum, where 93 young fledged, the highest number since 2008

They’re back! This morning the first 2 swifts were seen exiting their nest boxes in the tower with another party of 11 spotted flying high overhead.
