The BSA platform for Principal Designersand Accountable Persons.
BSA 2022 compliance infrastructure for England HRBs — golden thread, Gateway 1, Gateway 2, and Gateway 3, handover, safety case, 16 KBI categories, occurrences, residents, and Part 5 — plus readiness scorecards, deadline calendars, and portal-day packs so you see gaps before a BSR visit. Statutory floor on every paid plan.

The Building Safety Act is a lifecycle problem.
England HRB duties span design, gateways, handover, and occupation. Generic project tools and document stores were not built for that statutory chain — Principal Designers and Accountable Persons need one coherent platform.
Golden thread across the whole life
BSA 2022 requires an accurate, accessible digital record from design through occupation (SI 2023/909 Part 4; s.88). Spreadsheets and shared drives break at handover — when the Accountable Person needs the record most.
Read the golden thread guideGateway packs the BSR will accept
Gateway 2 and 3 demand coordinated evidence, sign-off, and correspondence. One missing mandatory item delays construction or occupation — and email threads are not an audit trail.
Occupied duties do not stop at PC
Safety case, 16 KBI categories, occurrences, resident complaints, FRA, and BSR returns are ongoing AP/BSM obligations. Most tools stop at design — Threadsovereign does not.
Every duty-holder in one system
Principal Designers, clients, contractors, residents, and Accountable Persons need role-scoped access to the same building record — not five products and a shared inbox.
Under the Building Safety Act 2022, non-compliance can result in unlimited fines, project stoppage, and criminal prosecution of duty holders.
One platform for the full England HRB lifecycle.
Purpose-built for Building Safety Act duty-holders — not a document store or project tool with BSA checklists bolted on. Golden thread, gateways, handover, safety case, KBI, residents, and Part 5 in one auditable system, with statutory workflows on every paid plan.
Scattered tools, broken chains, compliance gaps
One platform, connected parties, structured BSA workflows
Built for the England HRB regime — not adapted from generic PM.
