The operating system for fire safety and electrical contractors.
Excel at every operation.
Supercharge your engineers. Impress your customers. Grow your business — with your back-office on autopilot.

Trusted by contractors registered with
Everything you need to run the job.
Built for how fire safety and electrical contractors actually work — from the site visit to the signed certificate, without re-keying anything.






A back-office that actually has your back.

Features
Nine certificate types. One system.
Your engineer completes a job, Opscel generates the certificate — formatted to the correct British Standard, every mandatory field validated before it leaves.
Fire Safety Certificates
BS 5839-1 Installation, Commissioning, Service, Modification • BS 5839-9 Emergency Voice Communication • BS 5266-1 Emergency Lighting • BS 5306-3 Fire Extinguisher Service • Cable Test Readings (Clause 36)
Electrical Certificates
BS 7671 EIC • EICR • Minor Works
Automatic Delivery
Every certificate includes digital signature capture, automatic numbering, and PDF delivery straight to your customer's portal. No re-typing from handwritten notes. No missed fields flagged by your trade body.

One job. As many visits as it takes.
A fire alarm commissioning isn't one appointment — it's a job that takes three or four site visits. Opscel works the way you already think: one job number, multiple visits, one complete record.
Drag-and-drop calendar
See who's available, assign the right engineer
Multi-visit scheduling
Add visits as the job progresses, not upfront
Syncs with Google Calendar and Outlook
Engineers see their schedule where they already look

Defect to invoice, nothing re-keyed.
Your engineer services a fire extinguisher and finds a cracked hose on a CO₂ unit. They log the defect on-site. Back in the office, it's already a draft quote — Good, Better, or Best options ready to send.
Defect logging on-site
Engineers capture issues while they're still on the job
Good-Better-Best quoting
The customer approves from their portal with one click. It becomes a job. The job gets done. It becomes an invoice.
One flow, no re-keying
Defect → Quote → Approved → Job → Invoice. No chasing.

A portal your customers will actually use.
Your customers log in at portal.opscel.com — no app download, no password to remember. A magic link in their email gets them straight in.
Magic link authentication
From there they approve quotes, download certificates, and view invoices across all their sites.
Stop fielding requests
You stop fielding 'can you resend that certificate?' emails. They stop waiting for them.
Multi-site management
Customers with multiple sites see everything in one place

Built for how contractors actually work.
Works offline. Engineers fill out forms on a tablet in a plant room with no signal. The app syncs when they're back online. No lost data, no 'I'll do it when I'm back in the office.'
Your data stays yours
Every contractor company is fully isolated. Your customers, jobs, and certificates are never visible to anyone else.
BAFE, NICEIC, ECA, FIA ready
Certificate formats match what your trade body expects. We've mapped the mandatory fields from each standard so you don't have to cross-reference the spec.
