Assaya vs FireArrest: Fire Stopping Software for UK Contractors

Assaya vs FireArrest: the short version

If you want the quick answer, here's where each platform sits. Both are capable UK passive-fire tools — the difference is maturity versus model.

• FireArrest: an established, roughly eight-year-old UK platform with a broad, mature feature set, named installer customers and blue-chip end-client logos. Priced per user/seat, with a 7-day free trial and a 15% annual discount.
• Assaya: a modern golden-thread platform built and operated by fire-stopping contractor Rockfirepro Ltd. Flat pricing with unlimited operatives, drawings and jobs per tier, plus distinctive record-integrity features like hash-chained history and QR label linking.
• Common ground: both cover fire stopping, fire doors and fire dampers, both work offline in the field, and both keep an auditable record history.

Pricing: flat vs per-seat

The biggest practical difference is the pricing model. FireArrest, like many platforms in this category, is priced per user/seat — its public tiers are billed per user each month, with a 7-day free trial and a 15% discount for paying annually. That model is clear and common, but the bill grows as you add operatives, so scaling your team scales your software cost.

Assaya is flat. Each tier includes unlimited operatives, unlimited drawings and unlimited jobs — there is no per-seat or per-drawing meter — so you can put your whole crew on it for one predictable price. Early firms can also lock in founder pricing. If your headcount moves up and down with projects, a flat licence takes the maths out of adding people.

We deliberately don't publish head-to-head per-seat figures here: seat prices change, and a pricing war helps nobody. The point is the shape of the bill. Per-seat rises with your team; flat doesn't.

Record integrity and the golden thread

For the Building Safety Act era, how a record proves it hasn't been tampered with matters as much as what it captures. FireArrest provides an 'uneditable activity log' — an audit trail of changes — which is a solid, well-understood approach.

Assaya's distinct approach is cryptographic. Every record is written into a hash-chained history that is tamper-evident by design: altering an entry breaks the chain, so the integrity of the whole record is mathematically verifiable, not just logged. Assaya also adds QR label linking — scan a physical sticker on site to bind it to a specific seal — a recurring inspection scheduler aligned to the Fire Safety (England) Regulations 2022 cadence for doors and dampers, and a client golden-thread portal that gives your customer a live, read-only register with share links.

These aren't claims that FireArrest can't record a golden thread — it can. They're the areas Assaya has chosen to push hardest: provable immutability, physical-to-digital linking, and a client-facing register.

Feature overlap: where FireArrest and Assaya meet

It's worth being clear about how much these platforms share. FireArrest has spent around eight years maturing its product, and it shows: pin-on-floorplan capture, photo capture with annotation, custom forms, automatic reports and invoices, cost/materials/VAT tracking, offline mode, Microsoft 365 SSO (which it markets as an industry-first), geofencing, a document library, and PDF/Excel export. That is a genuinely broad, well-rounded toolset, and its track record is a real strength.

Assaya covers the core field workflow too — an offline-first app your operatives use on site, records tied to your drawings and to physical QR labels, a recurring inspection scheduler, and a live register you can share straight to your client — with its emphasis on record integrity and flat, no-meter pricing. If your priority is the longest, most mature feature list, FireArrest's maturity counts. If it's tamper-evident records, flat team pricing and a contractor-built workflow, that's where Assaya is focused.

Built and operated by a live fire-stopping contractor

Assaya is built and operated by Rockfirepro Ltd, a working fire-stopping contractor. The people designing the software run the same installs, inspections and sign-offs you do, so the workflow is shaped by day-to-day site reality rather than assumptions.

To be fair, FireArrest shares this DNA: it launched in 2017 in partnership with Latimer Fire Protection, a fire-stopping contractor, and is now owned by Cube Purple Ltd. Both products come from people who know the trade. The difference today is that Assaya is still run hands-on by a live contractor and is being built with current technology and a flat commercial model aimed squarely at growing subcontractors.

Accreditations and compliance

Both platforms take compliance seriously, and their credentials are worth comparing directly rather than assuming one set beats the other.

The two hold different certifications rather than a strictly better or worse set. FireArrest's include ISO 9001 and Fire Aware, which reflect its maturity; Assaya's centre on data security, procurement and Building Safety Act alignment. Match them to what your clients, frameworks and PQQs actually ask for.

• FireArrest: ISO 9001, Fire Aware certified, IFSM membership, and AES256 encryption stated.
• Assaya: Cyber Essentials certified, Constructionline Gold, Building Safety Act certified, UKAS-accredited SSIP for health & safety (via Once For All), and Social Value — UK-hosted in London.
