// For fire & security installers

Every system installed, serviced and on record.

Fire alarms, emergency lighting and security systems are installed once and serviced for years - and every visit has to be evidenced. DuoApp keeps installs, servicing schedules, sign-offs and engineer cards in one app your engineers will use, with clients able to see their own records.

// Sound familiar?

Safety-critical work, run on spreadsheets.

Fire and security firms carry real responsibility, but most still run servicing on spreadsheets and paper. These are the problems they tell us about most.

Service visits that slip

Six-monthly fire alarm services and annual emergency lighting tests tracked on a spreadsheet, until a client's insurer asks for the records.

Install progress by phone call

Cabling, first fix, devices, commissioning - you find out where each job is by ringing round.

Evidence scattered everywhere

Test results, photos and signatures on paper, on personal phones and in email, so pulling a site's history takes an afternoon.

Engineer cards and vetting

ECS cards, DBS checks and training expire without anyone noticing until a client or certification body asks.

Remedials never quoted

Faults found on a service visit are written on a sheet and never turned into a quote or an invoice.

Clients chasing paperwork

Facilities managers email for service reports you've already done - because they can't see them.

// How DuoApp helps

Built around how fire and security firms work.

Everything below is included in the same £10 per user, for install engineers, service engineers and the office alike.

Installs and servicing in one view

Break installs into the stages you price for, and set up maintenance contracts as tasks that repeat monthly, six-monthly, yearly or at any interval. The next visit appears when the last is done, and overdue servicing stands out.

  • Install stages by floor or area
  • Recurring service visits at any interval
  • Overdue servicing flagged

Commissioning and service sign-offs

Checklists for commissioning and each service visit, with photos, notes and a signature. Every record is timestamped and stored against the site, with a full audit trail.

  • Pass / fail / N/A checks
  • Photos and signatures on every record
  • Works offline and syncs later

  • Access set per role and per site
  • Clients never see your rates
  • Fewer requests for paperwork

Engineer cards and vetting - tracked

  • Expiry warnings for every card
  • Approval inbox for new documents
  • Ready for audits
More on Document Compliance →

Fire door and fire stopping inspections

Quarterly fire door inspections, fire stopping and compartmentation checks, fire safety equipment logs and fire risk assessments from ready-made templates, against each block or plot. Photos can be mandatory, inspections renew with reminders, and each record locks into a branded PDF.

  • Fire door inspections renew quarterly
  • Mandatory photo evidence
  • Golden thread pack for handover
More on Compliance & Certificates →

Remedials and variations signed off

Raise remedial work or a variation from site on your phone, send it for approval and keep a full audit trail, so faults found turn into work won.

  • Raised from site on a phone
  • Custom approvers per contract
  • Full audit trail

Everyone on the latest drawings

Mark device layouts, cause-and-effect documents or RAMS as required reading. DuoApp notifies everyone affected, blocks sign-off until they've opened it, and re-locks on every revision.

  • Required-to-view documents
  • Sign-off blocked until read
  • Re-locks on each revision
More on Document Alerts →

CIS and retention, built in

On new-build and fit-out work, deductions, verification status, retention and releases sit on every invoice, worked out for you.

  • CIS deductions and verification
  • Retention held and released
  • Split payments against real work
More on Retention & Deductions →

Faults and warranty callouts

Log faults and callouts after handover, schedule the visit and sign it off with photos, so warranty work is tracked rather than lost.

  • Triage and schedule callouts
  • Sign-off with photos
  • Full history per site

// Fire & security FAQs

Questions fire and security installers ask us.

Can DuoApp schedule fire alarm and emergency lighting servicing?
Yes. Service visits are recurring tasks that can repeat monthly, six-monthly, yearly or at any interval you set to match your contracts and the relevant standards. The next one appears when the last is completed, or a set number of days before it's due, and overdue visits are highlighted.
Does DuoApp produce BS 5839 or BS 5266 certificates?
There are no BS 5839 or BS 5266 certificate templates out of the box. Compliance & Certificates includes templates for fire risk assessments, fire safety equipment logs, fire door inspections and fire stopping, and admins can build their own. Certificates produced in your existing software can be recorded with the PDF uploaded, so the checks, photos, signatures and certificate sit together.
Can our clients see their service records?
Yes. Client contacts can be added as users who see only their own sites - visits, reports and photos - without seeing your costs. They're the same £10 per user.
Does it work for CCTV, intruder and access control too?
Yes. Installs and servicing work the same way for any system type - you set up the stages and checklists that suit each one.
Is DuoApp suitable for a small fire and security firm?
Yes. You pay £10 per user, per month, so a team of five costs £50 a month with every feature included. You can add and remove people as your team changes and you're billed pro-rata.
How much does it cost and is there a free trial?
£10 per user, per month plus VAT, with every feature included. There's a 14-day free trial of the full platform, and you can cancel any time from the billing screen.
