Know what is current
Drawings, strategies and records change. It should be clear which information currently represents the building.
Building information, made understandable
The Golden Thread belongs to the building.
My Golden Thread helps building owners, Accountable Persons and building managers understand, organise and preserve the information needed to demonstrate how their building is designed, managed and kept safe.

The essentials
What is the Golden Thread?
A Golden Thread is more than a folder of documents. It is a reliable and accessible record of what is known about a building, how it is designed, what safety measures it relies upon, what has changed and the evidence supporting those conclusions.
For buildings within the higher-risk regime in England, keeping prescribed information digitally is a legal duty. For every building, the underlying discipline is valuable: accurate information helps people make safer, better-informed decisions.
Learn what the Golden Thread meansWhy it matters
A record people can rely on.
Good information reduces uncertainty. It helps dutyholders, residents and the people working on a building understand the current position and the evidence behind it.
Know where it came from
Information should retain its source, revision, author, verification and history.
Know what changed
Significant alterations should be recorded clearly without erasing what came before them.
Preserve continuity
The building record should survive changes of contractor, managing agent and ownership.
Documents need context
Uploading documents isn't the same as maintaining a Golden Thread.
A meaningful Golden Thread connects information to the building, systems and decisions it describes. It makes status and uncertainty visible, rather than allowing a shared drive to become the apparent answer.
What does this relate to?
Is it current?
Who supplied it?
Has someone verified it?
What replaced it?
What remains unknown?
Our principles
How we think a Golden Thread should work.
Building-first
The record belongs with the building, not whichever organisation currently manages it.
Evidence-led
Claims about the building should be supported by identifiable evidence.
Transparent
Missing, conflicting or unverified information should be recorded honestly.
Auditable
It should be possible to establish who changed something and when.
Portable
Information should remain exportable and transferable.
Practical
Information management should support the people doing the work, not add bureaucracy.
In development
The My Golden Thread platform.
We're developing a dedicated platform for maintaining the controlled safety information and operational history of buildings.
Building Record
Design, strategy, responsibilities and key building information.
Safety Systems
Structured records for safety-critical systems and their dependencies.
Controlled Evidence
Revision-controlled documents with provenance, verification and evidential status.
Digital Logbook
Permanent operational history for testing, maintenance, incidents and attendance.
Change History
Record what changed, why, what was affected and what evidence resulted.
Verifiable Audit Trail
File-integrity checks and tamper-evident historical records.
