UK Building Safety Regulator 2-Year Review

What this countdown tracks

1 April 2028 is the expected date of the UK Building Safety Regulator's (BSR) first two-year operational review, coming two years after the regulator's new leadership arrangements landed in 2026. The review will assess whether the post-Grenfell regime is delivering on its safety and competence objectives for higher-risk residential buildings in England.

Background

The Building Safety Regulator was established under the Building Safety Act 2022 and is hosted within the Health and Safety Executive (HSE). Its jurisdiction covers "higher-risk buildings" in England — residential buildings of at least 18 metres or seven storeys containing two or more residential units — with powers across three Gateways during design and construction and a building-assessment and certification regime in occupation. The Act responded to the 14 June 2017 Grenfell Tower fire, which killed 72 people and which Sir Martin Moore-Bick's Phase 2 Inquiry report (September 2024) attributed to systematic dishonesty by product manufacturers, regulatory failure, and poor industry competence.

By 2025 the BSR had faced criticism for chronic backlogs in Gateway 2 design-stage approvals, with industry groups reporting median approval times running at 30+ weeks against a 12-week target. In February 2025, the Government announced a restructure that moved Gateway 2 approvals into a fast-track assessment pilot, appointed a new BSR chief executive, and separated the regulator more clearly from HSE's operational reporting line. Amendments under secondary legislation transferred additional functions in 2025–2026. A formal two-year operational review was committed to publicly by the Ministry of Housing, Communities and Local Government and HSE, anchored to the 2026 reorganisation. The Grenfell Tower Inquiry Phase 2 Report, published 4 September 2024, had made 58 recommendations and pointedly criticised the fragmented pre-2022 regulatory regime, naming manufacturers Arconic, Kingspan, and Celotex and condemning the former Department for Communities and Local Government. The Government's formal response, published in early 2025, accepted the majority of the recommendations in principle, including support for a single construction regulator. The BSR two-year review is the operational test of whether the architecture committed to in the 2025 response is delivering in practice, including the registration of 12,500 higher-risk buildings in England.

Why the date matters

The 2028 review is the first structured opportunity to test whether the 2025–2026 restructure fixed the BSR's capacity and decision-speed problems without softening safety. It will inform decisions on whether to hive the BSR out of HSE into a fully independent statutory body, whether Gateway scope should be narrowed or widened, and how registered building inspectors and building-control approvers are regulated. Findings will feed directly into the UK Government's response to the Grenfell Tower Inquiry Phase 2 recommendations.

What to watch for

• Approval times and backlog metrics at Gateways 1, 2, and 3.
• Assessment of BSR's independence from HSE.
• Progress on registration of Building Control Approvers and Inspectors.
• Data on Building Assessment Certificates issued in occupation phase.
• Compliance and enforcement action statistics against Principal Accountable Persons.
• Alignment with Welsh and Scottish building-safety regimes.
• Whether MHCLG proposes primary-legislation amendments post-review.
