What Assaya is
Assaya records the golden thread for passive fire protection and proves it. Every seal, fire door and fire damper is pinned to the drawing, backed by photographic evidence, and locked into a hash-chained history that can't be quietly edited after the fact. The line says it plainly: every seal, attested.
It's offline-first, so the field app keeps working in a plant room with no signal and syncs when you're back in range. Behind it sits an admin console for the office and a client golden-thread portal, so main contractors and building owners can see a live, read-only register of the work.
- Fire stopping, fire doors and fire dampers — all three trades native in every paid tier
- Offline-first field app, admin console and client portal
- Photographic evidence pinned to the drawing
- Hash-chained, tamper-evident record history
- UK-hosted in London, with UK data residency
Where OneTrace fits
OneTrace is an established UK software platform used across fire safety and by subcontractors. It's known for its QA-workflow approach — configurable forms, sign-off steps and branded reporting — and it's a capable tool that plenty of firms rely on.
The honest picture: OneTrace and Assaya overlap on the fundamentals. Both let you pin work to drawings, capture photos, work offline and give clients access to an audit trail. So the real decision isn't a checklist of who has which button — it's about the pricing model, how the record is built, and who built the tool.
Pricing: flat price vs the meter
This is where the two diverge most. Many platforms in this space meter what you use — a charge per user or per drawing — so the bill climbs as your team or your job list grows. Exact plans change, so always check a provider's current published pricing directly.
Assaya doesn't meter. One flat price per tier covers unlimited drawings, unlimited operatives and unlimited jobs, so you know exactly what you'll pay before you've dropped a single pin. Published tiers run Free, Solo (£120/mo +VAT), Crew (£180/mo +VAT), Business (£450/mo +VAT) and Enterprise (from £950/mo +VAT), with founder pricing available for the first firms on board and a month free on annual billing.
- No per-seat charge — add operatives without adding to the bill
- No per-drawing charge — you never have to merge floors to dodge a meter
- One predictable number per tier
Built by fire-stopping installers, not a generic forms tool
Assaya is built by Rockfirepro Ltd, a working passive fire protection contractor — a Building Safety Act–certified, Constructionline Gold firm whose health-and-safety competence is independently assessed under a UKAS-accredited SSIP scheme (Once For All, ISO/IEC 17020). The wizard, the statuses and the certificate-grade pack were designed by people who've knelt in the riser and had their own work inspected.
On the platform side, Assaya is Cyber Essentials certified and hosted in the UK, with your data kept in UK data residency. You own your records, and you can take them with you.
The compliance backdrop
Passive fire protection records have to stand up to scrutiny. The Building Safety Act 2022 introduced the golden-thread duty — accurate, accessible information about a higher-risk building, kept current through its life. Assaya is built around that idea: a continuous, attributable record rather than a folder of loose PDFs.
The Fire Safety (England) Regulations 2022 set out fire-door check duties for the responsible person in many multi-occupied residential buildings, while fire-damper and ductwork inspection is guided by recognised standards such as BS 9999. Assaya keeps door, damper and seal records in one place with dates, evidence and history, so the next inspection is easy to schedule and easy to prove.
Which should you choose?
If your priority is a configurable QA workflow inside a large, established platform and a metered plan suits you, OneTrace is a serious option worth trialling. If you want a purpose-built passive fire protection record — three trades native, a flat price with no meter, an offline-first app and a certificate-grade pack — built by installers and hosted in the UK, that's exactly what Assaya is for.
The good news: you can try Assaya free and see your own drawing pinned before you commit.

Join the founding listIs Assaya a like-for-like OneTrace replacement?
It covers the same core ground — pin-to-drawing capture, photographic evidence, offline working and client access — with a passive-fire focus, a flat no-meter price and a certificate-grade output pack. The best test is to trial both on one of your own jobs.
How is Assaya's pricing different?
Assaya charges one flat price per tier for unlimited drawings, operatives and jobs — no per-seat or per-drawing meter. Many platforms in this space price per user or per drawing, so always compare against a provider's current published pricing.
Does Assaya cover fire doors and fire dampers, or just fire stopping?
All three — fire stopping, fire doors and fire dampers are native in every paid tier, kept in one golden-thread record.
Where is my data stored?
In the UK. Assaya is hosted in London with UK data residency, and records are held in a hash-chained, tamper-evident history. The platform is Cyber Essentials certified.
Who builds Assaya?
Rockfirepro Ltd, a working passive fire protection contractor — Building Safety Act–certified and Constructionline Gold — so the tool is designed by people who install fire protection for a living.
