Exploring the legal battles emerging from the BSA 2022. Who pays for safety upgrades and ongoing management in a post-Grenfell world? A review of recent tribunal decisions.. Managing Building Safety Costs: A New Wave of Legal Disputes The landscape of building safety in the UK is undergoing a profound transformation, driven by the Building Safety Act 2022 (BSA 2022) and the enduring legacy of the Grenfell Tower tragedy. While the Act aims to create a safer built environment and protect leaseholders from exorbitant remediation costs, a new front line of legal disputes is emerging. Leaseholders, building owners, and developers are increasingly clashing in tribunals and courts over who bears the financial burden of historical safety defects and ongoing building safety management. Recent tribunal decisions are providing crucial insights into how the protections afforded to leaseholders are being interpreted and tested, setting precedents that will shape the future of building safety remediation and management across the country. Background The Grenfell Tower fire in 2017 exposed systemic failures in building safety regulations, construction practices, and oversight. The subsequent Hackitt Review recommended a fundamental shift in the regulatory regime, leading to the enactment of the BSA 2022. A cornerstone of this legislation is the protection of leaseholders from the costs of remediating historical safety defects, particularly those related to cladding. The Act introduced a complex hierarchy of financial responsibility, placing the primary burden on developers and building owners, with strict conditions under which leaseholders can be asked to contribute, primarily for non cladding defects and only if certain financial thresholds are met. Prior to the BSA 2022, the responsibility for remediation costs often fell squarely on leaseholders, leading to financial hardship, unsellable homes, and immense stress. Government schemes like the Building Safety Fund (BSF) were introduced to provide some relief, but the scale of the problem meant these funds were often insufficient or slow to disburse. The BSA 2022 sought to codify and strengthen these protections, introducing "leaseholder protections" and "qualifying lease" criteria to define who is protected and under what circumstances. It also established the Building Safety Regulator (BSR) within the Health and Safety Executive (HSE) to oversee the new regime for higher risk buildings, including the gateway process (Gateway 2 and 3) for design and construction approvals. The BSA 2022 also significantly amended the Regulatory Reform (Fire Safety) Order 2005 (RRO 2005), expanding the duties of responsible persons and introducing new requirements for managing building safety risks. This includes the preparation of a safety case report for higher risk buildings, demonstrating how fire and structural safety risks are being managed. The Approved Document B (ADB) of the Building Regulations, alongside British Standards like BS 9991 and BS 9999, provides guidance on fire safety design, but the BSA 2022’s emphasis on proactive risk management and ongoing safety assurance goes far beyond these prescriptive standards. Furthermore, Publicly Available Specification (PAS) 9980 has become a critical tool for assessing external wall fire risk, informing remediation strategies. Key Developments Recent months have seen a surge in applications to the First tier Tribunal (Property Chamber) – FTT – by building owners seeking to recover costs from leaseholders, and by leaseholders challenging these demands. These cases are pivotal in defining the practical application of the BSA 2022's leaseholder protections. One recurring theme in FTT decisions involves the interpretation of "qualifying lease." For a lease to be a qualifying lease, it must have been granted for a term of more than 21 years, the dwelling must be in a relevant building (at least 11 metres or 5 storeys), and the leaseholder must have owned the dwelling on 14 February 2022. Disputes often arise over whether a lease meets all these criteria, particularly in shared ownership schemes or where lease assignments occurred close to the cut off date. The FTT has generally adopted a strict interpretation, meaning that even minor deviations can exclude a leaseholder from protection, leaving them potentially liable for significant costs. Another critical area of contention is the scope of "relevant defects." The BSA 2022 primarily focuses on defects that pose a risk to the safety of people in or about the building, specifically those related to the external walls, common parts, and structural elements. Building owners are attempting to pass on costs for non cladding defects, such as internal fire compartmentation issues, inadequate fire doors, or missing fire stopping. The FTT is scrutinising these claims carefully, requiring robust evidence that the defects fall within the statutory definition and that the proposed remediation work is
