11th December 2025 - Industry and Regulators Committee’s report Published

The Industry and Regulators Committee’s report The Building Safety Regulator: Building a better regulator, whilst welcoming the increased scrutiny the Building Safety Regulator has brought to the design, construction and management of buildings in the interest of safety, also warns that the delays mean the Government is in danger of missing its target to build 1.5 million homes by 2029.

June 2025 - ATLG Open Letter in Response to the Building Regulations Guidance Review

The significance of understanding and accurately interpreting the Approved Documents (ADs) as the primary guidance for compliance with Building Regulations cannot be overstated. As one of the primary user groups of Building Regulations guidance, it is essential that everyday practitioners are involved and consulted as part of the development, drafting, and quality of guidance. Since the Government’s announcement of the Building Safety Regulator’s (BSR) review of the ADs, the Architectural Technical Leads Group (ATLG) has been engaged in discussions and has now drafted a series of outline recommendations in support of the BSR’s work.

The open letter is endorsed by 63 leading UK practices, they constitute a significant proportion of the AJ100 list.
