A complete timeline of Building Safety Act milestones -- from the Grenfell Tower fire through to upcoming deadlines. Know what's happened, what's coming next, and what needs your attention now.
The Fire Safety Order replaced over 70 pieces of fire safety legislation with a single framework, placing fire safety duties on the "Responsible Person" for all non-domestic premises including common parts of residential buildings. It remains the foundation that the Building Safety Act builds upon.
A fire at Lakanal House in Camberwell killed 6 people, including a baby. The coroner's 2013 inquest recommended clearer building safety guidance and a review of Approved Document B -- recommendations that were largely unacted upon until after the Grenfell Tower fire.
The fire at Grenfell Tower in North Kensington killed 72 people and became the catalyst for fundamental reform of building safety regulation in the UK.
Dame Judith Hackitt's Independent Review of Building Regulations and Fire Safety recommended a complete overhaul of the regulatory system, including a new regulator and the "Golden Thread" of building information.
The Phase 1 report focused on the events of the night of the fire, making recommendations for improved evacuation procedures, building safety, and fire service operations.
Clarified that the Fire Safety Order applies to the structure, external walls, and flat entrance doors of multi-occupied residential buildings. Closed a regulatory gap that had existed since the Grenfell fire.
The Building Safety Act 2022 became law, establishing a new regulatory framework for higher-risk buildings including the Building Safety Regulator, duty holder regime, and the Golden Thread requirement.
The Building Safety Regulator (BSR) was formally established as a division of the Health and Safety Executive, with responsibility for overseeing the safety of higher-risk buildings. It left the HSE to become a standalone body on 27 January 2026.
Introduced mandatory fire door checks (quarterly for flat entrance doors, annually for common area doors), requirements for wayfinding signage in higher-risk buildings, and evacuation alert systems for buildings with simultaneous evacuation strategies.
Building owners and managers of existing higher-risk buildings could begin registering with the Building Safety Regulator, providing key building information.
The deadline for registering all existing higher-risk buildings with the Building Safety Regulator. The BSR became fully operational, with powers to enforce the new regime.
The Higher-Risk Buildings (Management of Safety Risks etc) (England) Regulations 2023 came into force with section 83 of the Act. A Principal Accountable Person must prepare a documented Residents' Engagement Strategy, consult residents on it for no less than three weeks, and keep it under review -- alongside the safety case and complaints duties.
A Principal Accountable Person must maintain and make available Key Building Information (KBI), forming part of the Golden Thread of building safety information for all registered higher-risk buildings.
Duty holders must report structural and fire safety occurrences in higher-risk buildings to the BSR. This includes any event that causes or is likely to cause a significant risk to life safety.
A Principal Accountable Person can apply to the BSR for a Building Assessment Certificate. The BSR assesses whether the Accountable Person is managing building safety risks effectively.
The Phase 2 report examined the wider causes of the Grenfell tragedy, including the role of government, industry, and product manufacturers in the systemic failures that led to unsafe cladding on buildings. Its first recommendation was a single construction regulator.
The Building Safety Regulator can request safety case reports from a Principal Accountable Person. These demonstrate how building safety risks are being identified, assessed, and managed.
The government accepted the findings and committed to act on all 58 recommendations, including a single construction regulator, a Chief Construction Adviser, and consolidating fire safety functions under one department.
The first of three amendment booklets took effect (circular 03/2024): references to BS 476 removed for reaction to fire and roofs, new guidance on sprinklers in care homes, and a consequential update to Regulation 38.
Parliament approved the regulations setting out how the Building Safety Levy operates, ahead of the levy taking effect on 1 October 2026. Draft amendment regulations making minor changes were laid on 2 July 2026.
MHCLG published statutory guidance for Responsible Persons ahead of the Residential PEEPs duty, alongside a Responsible Person's Toolkit of schemes that meet the regulations.
Asked by MHCLG to review the definition after the Phase 2 report, the BSR found the current 18m / seven-storey threshold appropriately reflects the evidence and recommended no change to scope for now. The definition instead moves to a continuous, structured review.
The Building Safety Regulator left the Health and Safety Executive to become an executive non-departmental public body sponsored by MHCLG, with a board chaired by Lord Andrew Roe -- the first structural step towards the single construction regulator.
The Fire Safety (Residential Evacuation Plans) (England) Regulations 2025 made Residential PEEPs a legal duty in England. Responsible Persons must use reasonable endeavours to identify relevant residents -- those with a mobility, sensory or cognitive condition affecting evacuation -- and offer each a person-centred plan. It applies to buildings of two or more domestic premises at 18m or seven storeys, and to buildings over 11m on a simultaneous evacuation strategy.
The BSR's 14-week review of Approved Document B ran from 25 March to 1 July 2026, covering a combustibility threshold for elements of structure, evacuation lifts in residential buildings above 18m, "specialised housing" terminology, and guidance on roofs including solar PV.
Homes England opens the buildings-under-11-metres cladding fund on 17 August 2026 for an 8-week application window, submitted through the Cladding Safety Scheme Building Remediation Hub. Applications must come from the responsible entity or their authorised representative -- gov.uk states that "Leaseholders and residents cannot apply directly" -- which places the whole application burden on the RTM company, RMC or managing agent. An application cannot be submitted without a FRAEW, and an FRA where available, so the evidence pack must be assembled before the window opens. Funding covers buildings containing 2 or more dwellings; works started before 9 July 2026 are ineligible. There is no pre-registration or early access, and a 6-week lead-in was given for responsible entities to prepare. The window therefore closes around 12 October 2026 -- that closing date is DERIVED from "the end of the 8-week application window" and is not stated explicitly by gov.uk; only the 17 August opening is published.
The 2026 Approved Document B amendment booklet (circular 04/2024) comes into force, recommending second staircases in new residential buildings above 18m. An 18-month transitional period applies to applications deposited before that date.
The levy applies in England to certain building control applications for works creating new dwellings or purpose-built student accommodation bedspaces, and to changes of use to residential. Developers pay before completion or occupation, whichever is earlier.
The third amendment booklet (circular 05/2024) removes the remaining references to BS 476 in relation to fire resistance, completing the move to the European classification system.

Coming, but not yet dated
Three changes are government policy without a commencement date, so they are not on the timeline above. The single construction regulator is the Grenfell Inquiry's first recommendation: the consultation on its shape closed on 20 March 2026, a full response was promised for summer 2026, and the government intends to stand the body up in 2028 with legislation later in this Parliament. The scope of the higher-risk regime now moves under continuous review by the BSR rather than a one-off widening, after its December 2025 review found no case for changing the 18m / seven-storey threshold. And a fully digital Golden Thread remains the direction of travel from the Hackitt Review, with no date set for mandatory digital record-keeping. Treat all three as intent, not deadlines.
