Swifts visit the UK between April and August, during which time they breed and raise their chicks before heading off to warmer climates for the winter. Unlike swallows and house martins, swifts prefer to nest in existing holes, cracks, and crevices, often in older buildings. Modern construction, with its improved energy efficiency and airtight designs, has reduced these natural nest sites, making swifts increasingly dependent on artificial nesting options, like nest boxes or specially designed bricks.
As a housebuilder, we have a unique opportunity to help. One simple, cost-effective solution is the installation of “swift bricks” – hollow bricks that replace a standard brick in a home’s construction. These clever little cavities provide nesting sites for swifts when traditional options are blocked or lost. And the best part? Swifts are tidy tenants, so homeowners often won’t even notice them!
