Golden Thread Starter Guide

What the law requires

The golden thread is the coherent, up-to-date building-safety record duty holders and the BSR can rely on. Works-phase duties sit in SI 2023/909 Part 4; occupied keep and provide duties sit in BSA s.88–s.89 and SI 2024/41 (Schedule 1 prescribed content; Schedules 2–3 for residents and other prescribed persons). Change of Accountable Person triggers BSA s.90 — not s.94.

Key clocks

Keep prescribed information
BSA s.88 + SI 2024/41 Schedule 1 — occupied keep-list must stay current.
Change of AP
Outgoing AP prescribed information under BSA s.90 / SI 2024/41 reg.13 (presence ≠ legal adequacy).
MOR in the thread
Occurrence records and BSR references form part of the occupied evidence base (s.87 / SI 2023/907 reg.6).

Operating checklist

The golden thread is the coherent, up-to-date record of building safety information. For England HRBs it must be maintained through design, construction, and occupation so duty holders and the BSR can rely on it. Works-phase duties sit in SI 2023/909 Part 4; occupied keep / provide duties sit in BSA s.88–s.89 and SI 2024/41 (Schedule 1 prescribed content; Schedules 2–3 resident / owner provision).

What the golden thread must achieve

Accurate, accessible information about the building and its safety-critical elements (BSA s.88)
Clear accountability for creating, reviewing, and updating information
Traceability of changes from design through to occupation
Evidence that supports gateway decisions, the safety case, BAC packs, and regulator requests
Prescribed occupied content mapped to SI 2024/41 Schedule 1 — not an informal document dump

Information to capture at design

Fire strategy and supporting calculations
Structural design assumptions and revisions
Product specifications with fire performance data
Value engineering and substitution decisions with safety impact
Coordination records between design disciplines
Gateway 1 / 2 pack versions retained with approval status

Information to capture during construction

As-built drawings and marked-up design changes
Installation certificates and commissioning records
Inspection and test results for regulated systems
Photographic evidence for concealed works where required
Snag items affecting fire or structural safety until closed
Change-control decisions linked back into the golden thread and safety case narrative

Handover into occupation (BSA s.76 + s.90)

s.76 occupation handover package assembled (information the AP needs to manage safety risks) — distinct from Gateway 3 completion alone
AP / BSM responsibility-transfer records where roles change (not labelled as BSA s.94)
On change of Accountable Person: outgoing AP prescribed-information transfer under BSA s.90 with SI 2024/41 reg.13 pack themes (all eight mapped themes — presence attestation; legal adequacy remains with the duty-holder)
Incoming AP and regulator information pathways understood

Information for occupation (HRB)

Safety case evidence and structural / fire assessments (SI 2023/907)
Key Building Information category evidence retained alongside the thread (SI 2023/396)
Maintenance regimes and inspection intervals
Mandatory occurrence logs, attention dates, notices, full reports, and BSR portal references (BSA s.87 / SI 2023/907 reg.6)
Resident engagement records, Schedule 2 / 3 fulfilment, and complaint resolutions under reg.10 / reg.12 (any 10 UK working-day complaint window is platform / organisational policy — not a fixed national SI clock; s.89 / s.91B)
Building Assessment Certificate supporting material kept coherent with the live thread
Registration change evidence retained (SI 2023/315 reg.4 — 14 relevant days)
Companion FSER / FRA / fire-door / EEIS / PEEP records linked where they support building safety risk management (SI 2022/547 adjacent)

Structuring your golden thread

Organise by building → system → asset where possible
Apply consistent naming and version numbering
Link documents to duty holders and approval dates
Separate draft, approved, and superseded records
Maintain an audit trail for all changes
Control resident-visible vs duty-holder-only information deliberately (Schedules 2–3)

Common pitfalls

Safety-critical PDFs stored in email threads without version control
Contractor substitutions not reflected in the golden thread
Gateway packs that diverge from site reality at handover
No single owner for information updates after practical completion
Resident-facing information not connected to safety case evidence
Confusing SI 2023/908 consequential amendments with registration duties (use SI 2023/315 reg.4)
Treating AP responsibility transfer as ‘s.94’ (s.94 = regulator complaints)
Starting the MOR 10-day clock from create date instead of AP attention date
Treating a 10 UK working-day complaint SLA as a statutory national clock under reg.12
