TL;DR
The Scottish parliament has passed legislation making swift bricks mandatory for all new buildings, aiming to support declining swift populations. This move contrasts with delays in England and other UK nations. The law will be implemented after a 12-month consultation.
The Scottish parliament has passed a law requiring all new buildings to include swift bricks where reasonably practical and appropriate, marking a major policy shift for bird conservation in Scotland.
The legislation was backed by MSPs across parties, following an amendment by Scottish Green MSP Mark Ruskell. The law aims to provide nesting sites for swifts and other cavity-nesting birds such as sparrows, starlings, and house martins, which have seen significant population declines.
The move was supported by wildlife campaigners and ministers, including Gillian Martin, who highlighted the species’ decline of 60% since 1995 and its status on the red list of birds of conservation concern. The legislation will be enacted after a 12-month consultation to establish appropriate building standards for the bricks.
Why It Matters
This decision represents a concrete step in wildlife conservation, addressing habitat loss caused by modern renovations and insulation schemes that eliminate traditional nesting sites. It sets a precedent for other UK nations, especially as delays and opposition persist elsewhere, notably in England and Wales.
Wildlife advocates see this as a landmark victory that could inspire similar policies nationwide, potentially reversing declines in swift populations, which are now fewer than 40,000 pairs in Britain.

Background
In recent years, efforts to mandate swift bricks have faced challenges, with England’s government opting to include them only in planning guidance rather than law. Campaigners have argued that this approach is ineffective, as studies show many planned installations are not carried out. Gibraltar has demonstrated success with similar policies, seeing population stabilization and growth among swifts.
Scotland’s move follows a four-year campaign, with the Green MSP Mark Ruskell leading efforts to secure legal requirements. The Welsh government rejected similar mandates last year, citing concerns over developer flexibility, but Scotland’s legislation aims to overcome such hurdles through a formal law.
“This iconic species was once a very common sight across Scotland, particularly in urban areas, but they are under threat, declining by 60% since 1995, which has led to them being on the red list of birds of conservation concern.”
— Gillian Martin, Scottish Minister
“Swifts join our communities every summer, but they are becoming rarer everywhere. I hope this legislation inspires other UK lawmakers to follow Scotland’s lead.”
— Mark Ruskell, MSP
“Scotland’s decision on swift bricks is a significant step in ensuring the survival of this species, which has come to depend so much on us.”
— Prof John Cortes, Gibraltar Environment Minister

Key Questions
What are swift bricks?
Swift bricks are specially designed nesting cavities that can be incorporated into new buildings to provide safe nesting sites for swifts and other cavity-nesting birds.
Why are swift populations declining?
Their decline is mainly due to habitat loss from modern renovations and insulation schemes that eliminate traditional nesting sites on buildings.
Will all new buildings in Scotland have to include swift bricks?
Yes, the law mandates their inclusion where reasonably practical and appropriate, following the completion of a consultation process to establish standards.
How does this compare to policies in other UK nations?
While Scotland is implementing a legal requirement, England and Wales have only included guidance without mandatory standards, and Wales rejected mandates last year.
What is the expected impact of this law?
It aims to provide immediate nesting sites for swifts, helping to stabilize and potentially increase their populations across Scotland.
