Understanding the Building Safety Act 2022: A Paradigm Shift in UK Construction
The Building Safety Act 2022 is the most significant change to UK building regulation in decades, and it is now fully in force. The Building Safety Regulator is operating, the gateway regime controls progress on higher-risk buildings of at least 18 metres or 7+ storeys, and competence duties apply to all building work. The question for construction professionals is no longer when the requirements arrive, but whether their golden thread, gateway submissions and competence records stand up to scrutiny on live projects.
Scope and Application
The Act applies to specific building types during design, construction, and occupation phases:
Buildings in Scope
- Residential buildings: 18+ metres high or 7+ storeys
- Care homes and hospitals: 18+ metres high or 7+ storeys (in scope during design and construction, though the occupation-phase regime does not apply to them)
- Mixed-use buildings: In scope where the building meets the height threshold and contains at least two residential units
- Future expansion: Government may extend scope to other building types
Key Phases
- Design Phase: Gateway 1 (planning permission stage)
- Construction Phase: Gateway 2 (before construction begins)
- Occupation Phase: Gateway 3 (before occupation)
- In-occupation: Ongoing duties for Accountable Person
The Golden Thread Requirement
The Golden Thread mandates that building and fire safety information must be accurate, accessible, structured, and up-to-date throughout the building's lifecycle:
Information Requirements
- Design information: Plans, specifications, risk assessments
- Construction records: As-built drawings, material certificates, testing results
- Change documentation: All modifications and their safety implications
- Competency evidence: Qualifications and experience of key personnel
- Safety case information: Demonstrating building safety throughout lifecycle
Digital Requirements
Information must be:
- Structured: Organised according to recognised standards
- Accessible: Available to relevant parties when needed
- Accurate: Current and factually correct
- Complete: Comprehensive for safety decision-making
Gateway System Overview
The gateway process ensures building safety is properly considered at key project stages:
Purpose and Objectives
- Early intervention: Identifying and resolving safety issues before they become embedded
- Progressive assurance: Building confidence in safety throughout the project
- Regulatory oversight: BSR review at critical decision points
- Information continuity: Ensuring Golden Thread development through project stages
- Competency verification: Confirming appropriate expertise at each stage
Gateway Decision Authority
- Gateway 1: Decided by the local planning authority, with the regulator as statutory consultee on fire safety
- Gateways 2 and 3: Decided by the BSR as building control authority for higher-risk buildings
- Local authorities: Continued planning functions and building control for non-higher-risk work
- Independent oversight: Separation from commercial interests
Gateway 1: Planning Permission Stage
Gateway 1 operates at the planning application stage for in-scope buildings:
Submission Requirements
- Fire statement: The fire safety strategy for the development, at the level of detail the planning stage allows
- Site and access information: Fire service access, water supplies and site constraints
Construction control plans, the fire and emergency file and competence declarations come later, with the Gateway 2 application; Gateway 1 is deliberately lighter touch.
Fire Statement Content
The fire statement sets out the fire safety approach across areas such as:
- Means of escape: Safe evacuation routes and procedures
- Facade design: External wall system fire performance
- Fire spread: Prevention of fire spread within and between buildings
- Access and facilities: Fire service access and firefighting facilities
- Fire detection: Systems for early fire detection and alarm
- Management systems: Ongoing fire safety management arrangements
Gateway 1 Assessment Process
- Fire statement submission: Made with the planning application for in-scope buildings
- Statutory consultation: The regulator reviews fire safety matters and advises the planning authority
- Technical review: Assessment of the fire safety strategy at the level of detail planning allows
- Planning decision: The local planning authority determines the application, informed by that advice
Planning for Gateway Timescales
- Gateway 1: Runs on planning application timescales: the fire statement should be ready with the application
- Gateway 2: A statutory 12-week determination period applies for new higher-risk buildings, but assessments have frequently taken longer in practice; build realistic allowances into the programme
- Information requests: Incomplete or inconsistent submissions stop the clock and cost weeks
- Pre-application engagement: Strongly recommended to surface complex issues before formal submission
Gateway 2: Construction Commencement
Gateway 2 approval is required before any construction work begins:
Submission Requirements
- Full plans and fire and emergency file: Detailed design and a refined fire safety strategy demonstrating compliance
- Construction control plan: Detailed procedures for managing construction safety
- Quality management: Systems ensuring construction quality and compliance
- Information management: Plans for maintaining Golden Thread during construction
- Competency evidence: Qualifications and experience of construction team
- Change control: Procedures for managing design changes during construction
Fire Safety Strategy Development
The fire safety strategy must demonstrate continued compliance following design development:
- Design evolution: How fire strategy has been maintained through detailed design
- Product selection: Evidence of appropriate material and system choices
- Interface management: How different building systems interact safely

How the Regime Came into Force
The Act reached full operation in stages, and all of them are now behind us:
Establishment
- Planning gateway: Fire safety scrutiny at planning stage for in-scope buildings
- Building registration: Existing higher-risk buildings registered with the BSR
- BSR operational: The Building Safety Regulator acting as building control authority for higher-risk buildings
Full Operation
- Gateways 2 and 3: Regulator approval required before construction and before occupation
- Dutyholder and competence duties: In force for all building work, not only higher-risk buildings
- Golden Thread: Digital safety information duties live for higher-risk buildings
- Accountable Person duties: Occupation-phase responsibilities, safety cases and resident engagement operating
For teams starting a higher-risk project today, the practical consequence is that transitional arrangements have largely run their course: submissions are judged against the full regime, and gateway determination periods, which have frequently run longer than the statutory targets, need to be planned into the programme from the outset.
