Use this checklist to verify that your project has the records, approvals, and duty-holder arrangements required under the Building Safety Act 2022 and the Higher-Risk Buildings (Descriptions and Supplementary Provisions) Regulations 2023. Tick each item when evidence exists and is linked in your golden thread.
Project setup & duty holders
- Client has appointed a Principal Designer and Principal Contractor in writing
- Duty-holder roles are recorded for design, construction, and (where applicable) occupied phase
- Building is classified as HRB or non-HRB with documented rationale

- Change control process defined for design and safety-critical information
Gateway 1 (planning)
- Fire statement prepared where required for relevant applications
- Consultation responses from the Building Safety Regulator (BSR) logged
- Design intent for fire and structural safety documented
- Key assumptions and constraints recorded for downstream gateways
Gateway 2 (pre-construction)
- Full design intent package assembled for BSR review
- Fire strategy, structural design, and MEP safety interfaces aligned
- Construction control plan drafted
- Change management procedure agreed before works commence
- Golden thread information requirements defined per asset/system
- Evidence that building work will not commence until BSR approval
Gateway 3 (completion)
- As-built information reconciled against design intent
- Fire safety and structural certification complete
- Resident engagement strategy (where HRB) prepared
- Safety case evidence compiled for handover to Accountable Person
- Defects and outstanding items tracked to closure
Golden thread & information management
- Single source of truth for safety-critical information identified
- Version control applied to regulated documents
- Audit trail for uploads, approvals, and changes
- Information linked to building, storey, and system level where practicable
- Access controls reflect duty-holder responsibilities
Occupied phase readiness (HRB)
- Accountable Person and Principal Accountable Person identified
- Safety case structure defined with evidence owners
- Mandatory occurrence reporting process understood
- Resident engagement and complaints pathways documented
- Building Assessment Certificate application plan in place
Contractor & supply chain
- Design changes from contractors routed through change control
- Product substitutions assessed for fire/structural impact
- Installation records and test certificates collected
- Snagging linked to safety-critical systems until resolved
Assurance before submission
- Internal peer review completed on Gateway pack
- Gaps flagged with owners and target dates
- Submission readiness review signed off by competent person
- BSR correspondence filed against each gateway decision
This checklist supports planning and assurance. Gateway requirements and HRB obligations should be verified against current BSR guidance and your legal advisers.
