This new report from Achilles, released during UK Construction Week in May 2025, reveals frontline insights into modern slavery risks across construction sites, and offers practical guidance to help the industry strengthen ethical labour practices. Based on data collected through Achilles’ Ethical Business Programme, the report draws from on-the-ground interviews with 9,834 workers representing 102 nationalities, across hundreds of sites in the UK and Ireland. These frontline insights provide a detailed view into the conditions facing those most at risk of exploitation.
