While the main framework of the Building Safety Act is in place, key details are still being filled in by secondary legislation. We provide a roadmap of what to expect next.. BSA Secondary Legislation: What's Still to Come in 2026 2027? The Building Safety Act 2022 (BSA) stands as a monumental piece of legislation, fundamentally reshaping the landscape of building safety in the UK. While its primary framework is firmly established, the true operational impact and granular detail are being progressively unveiled through a steady stream of secondary legislation. This phased implementation, a necessity given the Act's complexity and scope, means that fire engineers, building owners, developers, and residents alike must remain acutely aware of the ongoing legislative pipeline. As we navigate 2026 and look towards 2027, several crucial statutory instruments are anticipated, promising to further define responsibilities, refine processes, and embed the culture of safety that the BSA champions. The devil, as ever, is in the detail, and understanding these forthcoming regulations is paramount for effective compliance and practice. Background The BSA 2022 emerged from the tragic lessons of the Grenfell Tower fire, aiming to rectify systemic failures in building safety and accountability. Its core tenets include establishing the Building Safety Regulator (BSR) within the Health and Safety Executive (HSE), introducing a stringent new regulatory regime for higher risk buildings (HRBs), enhancing resident engagement, and extending liability for defective buildings. The Act itself provides the overarching legal framework, but its practical application is contingent upon a vast body of secondary legislation – statutory instruments (SIs) – which flesh out the specifics. Initially, much of the focus was on establishing the BSR's powers, defining HRBs, and implementing the "gateway" process (Gateways 1, 2, and 3) for HRBs. We've seen significant progress with the Building Regulations etc. (Amendment) (England) Regulations 2023, which brought into force many key provisions, including the duty holder regime and enhanced requirements for competence. The Building Safety (Leaseholder Protections) (England) Regulations 2022 and subsequent amendments have also been critical in addressing the contentious issue of cladding remediation costs. However, the journey is far from complete, with several areas still requiring detailed regulatory definition to ensure the BSA's full intent is realised. Key Developments Looking ahead to 2026 2027, the anticipated secondary legislation is expected to focus on several critical areas, refining existing provisions and introducing new requirements that will directly impact fire engineering practice and building management. One significant area is the ongoing development of competence requirements and certification schemes . While the BSA mandates competence for duty holders, the precise mechanisms for demonstrating and maintaining this competence are still evolving. We anticipate SIs that will further detail the requirements for independent third party certification bodies, potentially expanding the scope beyond specific roles to broader aspects of building design, construction, and management. This could include more specific criteria for fire engineers involved in HRB projects, aligning with the BSR's drive for a more professionalised industry. Further clarity is expected regarding the "golden thread" of information . While the principle is enshrined in the Act, the exact digital formats, data standards, and accessibility requirements for this crucial information management system are still being refined. SIs in this area will likely provide prescriptive guidance on how building safety information must be recorded, stored, and updated throughout a building's lifecycle, from design through to occupation and demolition. This will have profound implications for how fire strategies, fire risk assessments, and other critical safety documentation are managed and shared, moving beyond traditional paper based systems. The operationalisation of the BSR's enforcement powers is another area ripe for further legislative detail. While the BSR now has powers to issue compliance notices, stop notices, and prosecute breaches, the procedural aspects, including appeals processes and specific penalties for different types of non compliance, may see further refinement. This will be crucial for ensuring consistency and fairness in enforcement, providing clarity for those subject to the regulations. We also anticipate SIs that will address existing buildings beyond HRBs , particularly concerning the scope and application of the new safety case regime. While the initial focus has been on HRBs, the BSA provides powers to extend its provisions to other building types. While a full extension to all buildings is unlikely in the immediate future, we could see targeted SIs addressing specific risks or building categories that
