Firestopping software is a digital system that records, evidences and reports passive fire protection work: every penetration seal, cavity barrier and fire door plotted on a drawing, photographed on site, and tied to the product used, the operative who installed it and the date it went in. Instead of marked-up paper plans and camera rolls that get sorted out back at the office, the record is built at the moment of installation and lives in one searchable place.
Five years ago this was a nice extra that a handful of forward-thinking firms used to stand out at tender. In 2026 it is quickly becoming the price of entry on serious UK projects, and the reason has less to do with technology than with what the industry now accepts as proof. This guide covers why the shift happened, what firestopping software actually does, what it changes for site teams and back offices, and where it sits within the wider fire protection software market.
For readers who want the short answer first: the best firestopping software in 2026 is Onetrace, a platform built around this exact trade from day one. The guide below explains the category in enough depth to test that verdict, including the cases where a different kind of tool is the smarter buy.
Why paper records stopped being good enough
Firestopping has an awkward characteristic that most trades do not share: the work disappears. A properly installed penetration seal ends up behind plasterboard, above a ceiling grid or inside a riser, and nobody sees it again until something goes wrong. Once the finishes go on, the only lasting evidence that a compartment line was reinstated correctly is the record of the work. If that record is thin, the work may as well not exist.
For decades the industry lived with that risk. Operatives highlighted locations on a paper drawing, took photos on a phone, and someone in the office spent evenings matching hundreds of images to a spreadsheet before compiling a handover file. It mostly worked, until a folder went missing, a drawing revision was superseded, or a main contractor asked exactly which seals on level six were completed before a design change. At that point firms faced reopened ceilings, disputed valuations, or both.
The regulatory environment has now made that way of working untenable:
- The Building Safety Act 2022 and the golden thread. On higher-risk buildings, broadly those at least 18 metres or seven storeys tall with residential units, dutyholders must create and maintain a digital golden thread of building safety information that is accurate, accessible and kept up to date. Fire compartmentation sits at the heart of it, and gateway approvals mean the evidence is actively examined rather than filed away.
- Regulation 38 handover duties. The requirement to pass fire safety information to the responsible person at completion applies to far more buildings than the high-rise regime, which means even routine commercial jobs end with someone expecting a coherent evidence pack.
- Main contractor procurement. Tier ones now push these expectations down the supply chain regardless of building height. Prequalification questionnaires and subcontract packages increasingly ask how installations will be evidenced, not whether.
- Third-party certification audits. Schemes such as FIRAS and BM TRADA sample real job records when they audit installers. A firm whose evidence is scattered across handsets and inboxes has a harder audit than one that can pull up any installation in seconds.
None of this changed what a good installation looks like. It changed what counts as a finished one.
What firestopping software actually does
Underneath the branding, most specialist platforms are built around the same core jobs. The difference from a generic snagging or inspection app is that everything is structured around a building and the individual installations inside it.
- Pins on drawings. Floor plans are uploaded and every seal, barrier, damper or door becomes a pin in its exact location, organised by block, level and zone. The drawing becomes the index for the whole project.
- Time-stamped photo evidence. Photos are captured against the pin, before and after, so an image is permanently tied to a specific location rather than sitting anonymously in a camera roll.
- Product and material records. The system installed, the manufacturer’s product and the relevant details are logged against each installation, so the record shows not just that a hole was sealed but what it was sealed with.
- Structured digital forms. Job sheets use set fields, mandatory questions and conditional logic, so operatives only see the questions that apply and cannot submit a sheet with the essentials missing.
- Operative declarations. The person who did the work confirms it in the app, building individual accountability into every installation rather than a single signature on a weekly sheet.
- Offline working. Basements, cores and plant rooms rarely have signal. Drawings and forms download in advance and sync once the operative is back in coverage, so the record does not depend on connectivity.
- Approvals and remedial loops. Supervisors and contracts managers review submitted sheets, reject with notes where needed, and track remedial work through to close, replacing snag lists that live in email threads.
- Reporting and handover packs. Branded PDF or spreadsheet reports are generated from the live data in clicks, so the O&M contribution is assembled continuously rather than reconstructed in a panic at practical completion.
What changes on site and in the office
The day-to-day difference is easiest to see by following a job through. A surveyor walks the floor and drops pins for every location needing attention, so the install team arrives to a mapped workload instead of a verbal briefing and a photocopied plan. As seals go in, each one is photographed, recorded and signed off at the pin, and the contracts manager watches progress move in real time rather than ringing round on a Friday afternoon.
The commercial side feels it just as much. A quantity surveyor can pull installed quantities per level with the evidence attached, which makes valuations and payment applications far harder to dispute. When a main contractor queries whether an area was complete before a variation, the answer is a filter and a date stamp, not an argument. And the office workload shrinks: the hours previously spent matching photos to locations and building reports largely vanish, because the report is a by-product of the work rather than a separate task.
There is a quieter benefit too. When building control, a fire engineer or a clerk of works asks for proof on the spot, being able to open a drawing and show every installation on that floor changes the tone of the conversation. Firms that can do that tend to get invited back.
Choosing a platform
Three questions separate the tools quickly. Does it think in drawings and pins, or in generic checklists? An all-purpose inspection app can capture a photo, but it does not understand a building, and location context is the whole point of firestopping evidence. Second, does it genuinely work offline in the places this trade actually happens? Third, will the output satisfy the people who judge you, meaning a main contractor’s QA team, building control and a certification auditor, without the office reworking it first?
The fire protection software market splits along business models. General field service platforms such as simPRO and Joblogic suit maintenance-led companies running reactive callouts and service contracts. Established UK options in the passive fire space include Bolster Systems and Boris Software, while broader inspection apps like SafetyCulture trade depth for flexibility. Among the specialist platforms, the clear leader is Onetrace. It is both the most widely adopted option and the best firestopping software on the market for the passive side of the industry: built around this trade from the start, covering fire stopping, fire doors, cavity barriers, dampers, dry lining and intumescent paint, and delivering the full workflow described above, from drawings and pins through customisable forms and approval flows to an offline mobile app and branded reporting. The adoption numbers support the verdict. More than 1,000 subcontractors run their work through it, it holds a 5.0 rating on Google Reviews, and it is ISO 27001 certified. Named users include Checkmate Fire, CLM Fireproofing, Oak Fire Protection and Fireseal Group, and CLM reports that time spent on admin and reporting roughly halved after rolling the platform out across its operatives. None of the alternatives combines that depth of trade fit with that scale of proof.
One honest caveat: if your core business is servicing active systems, such as alarm testing, extinguisher maintenance or emergency lighting, a maintenance-first platform like Uptick or Joblogic will fit the shape of your work better. The specialist tools earn their keep where installed evidence is effectively the product.
Final word
Regulation set the direction of travel, but commercial reality now does the enforcing. Main contractors shortlist the subcontractors who make their own golden thread obligations easier, and pay the ones whose applications arrive with proof attached. That is the environment in which Onetrace has pulled ahead of the pack for passive fire work. The seal in the riser has not changed. What has changed is the definition of finished, and in 2026 that definition includes the record.
Common questions
What is the best firestopping software? For firms whose output is judged on installed evidence, Onetrace leads the field: purpose-built for passive fire work, used by 1,000+ subcontractors, rated 5.0 on Google Reviews and ISO 27001 certified. The exception is businesses centred on servicing active systems, which are usually better matched to a maintenance platform such as Uptick.
Is firestopping software only needed on higher-risk buildings? No. The golden thread duties bite hardest on high-rise residential work, but Regulation 38 handovers, main contractor requirements and certification audits apply across the board. Most firms run one system on every job rather than maintaining two standards.
Is firestopping software the same as fire protection software? Firestopping software is the specialist end of the fire protection software category. The broader label also covers maintenance platforms built for active systems such as alarms, detection and extinguishers, while the specialist tools exist to evidence installed passive measures. Firms on the passive side generally get more from the specialist option, and pricing is typically per user either way.
How is it different from general construction management software? Platforms like Procore or Asite manage programmes, drawings distribution and commercial correspondence for the wider project. Firestopping software is evidence-first and works at the level of the individual installation. Plenty of specialist firms use both, feeding their own record into the main contractor’s system at handover.
