- New: OBS (Observation Only) Button
You can now record non-coded observations on your EICRs — items that are noteworthy but don't carry a C1, C2, C3 or FI deficiency code.
A new blue OBS button sits alongside the existing code buttons. Use it for:
- Compliant items worth noting (e.g. "Installation uses pre-harmonised cable colours throughout")
- General comments about the installation condition
- Client advisories that aren't deficiencies
- Positive findings demonstrating thoroughness
On the PDF certificate, OBS items display as "Observation only" in the code column, clearly distinguishing them from coded deficiencies.
- Fixed: Reference Methods A and B were missing from the Circuit Designer installation method picker. Users selecting "Singles in Conduit" cable type could not select these methods, forcing incorrect use of Method C which gives higher (less conservative) current ratings.
Improvement
The reference method picker now dynamically filters to show only valid methods for the selected cable type:
T&E: C, 100, 101, 102, 103
SWA (PVC/XLPE): C, D, E, F
Singles in Conduit: A, B, C, E
MICC: C, E, F

- Re built: Qualifying Supervisor (QS) Signature System (enterprise users)
Streamlined Certificate Approval for Electrical Contractors
The QS Signature System in iCertifi provides a secure, efficient workflow for Qualifying Supervisors to review and approve electrical certificates remotely. Designed specifically for UK electrical contractors working under competent person schemes, this feature eliminates the need for paper-based sign-off processes.
How It Works
For Engineers in the Field
When an engineer completes a certificate, they can send it directly to their Qualifying Supervisor for review. The certificate data and a preview image are securely transmitted via iCloud, allowing the QS to review the work from anywhere.
For Qualifying Supervisors
QS devices receive incoming signature requests with full certificate details. The QS can review the certificate information, add their signature, and approve or reject the work - all from their iPhone or iPad. Approved certificates are automatically updated with the QS signature and name.
Key Features
Real-Time Notifications
Pending requests are highlighted with visual indicators.
Complete Audit Trail
Every approval and rejection is logged with full details including certificate reference, date, time, and QS name. The audit trail can be exported to CSV for record-keeping and compliance purposes.
Secure Transmission
All certificate data is transmitted securely via iCloud CloudKit, ensuring sensitive client information remains protected throughout the approval process.
Works Offline
Engineers can queue certificates for approval even without an internet connection. Requests are automatically sent when connectivity is restored.
Perfect For
Electrical contractors with multiple engineers requiring QS oversight
Competent person scheme members needing documented approval workflows
Businesses wanting to reduce paperwork and streamline certificate sign-off
QS professionals managing approvals across multiple jobs and engineers

Full Restore – Replaces all certificates with the backup. Now includes a confirmation step to prevent accidental data loss.
Backup Notifications
Shows which device created the backup and when
Flashing indicator when another device backs up
Smart sync detection prevents unnecessary alerts
- Calculate Zs now uses Ze at the distribution board (when recorded) instead
of Ze at origin, giving more accurate Zs values for circuits fed from sub-boards
• Fixed: Calculate Zs now correctly checks the Ze/Zs toggle setting before using
board impedance value
• Added: Calculate Zs support for EV Charger certificates
• Improved: Clearer alert messages when Ze falls back to origin value
- Test Results: Yellow box only shows when using Test Vision to show what was entered rather than on every test
- Stops yellow box appearing after entering every test result
- Other improvements and fixes
12.12.31 Jan 16
- Test Vision is here! Photo your test instrument , get results directly into your electrical certificate
Test Vision reads the result, identifies the test type, result, and populates your certificate fields automatically. No cable, no locked in to manufacturers software or instruments.
Batch Scanning Mode. For efficient testing workflows, the MFT Scanner supports batch operation. Take photos of multiple test results in sequence. Each scan adds to a queue visible in a table view. When you've captured all your readings, review the list. Tap individual items to populate specific circuit fields, or use the Add All function to import everything at once. This approach matches how electricians actually test. Complete all the measurements on a circuit, photograph each result, then import the batch. No context switching between testing and data entry.
- BoardVision 2.0 is here:
Building on our successful single circuit extraction. BoardVision 2.0 is an AI-powered distribution board scanner built into iCertifi. It uses computer vision to analyse photographs of UK consumer units and automatically extract all the circuit data. Take a photo of the board, BoardVision identifies every MCB, RCBO, and RCD. It reads the ratings, determines the type curves, and transcribes the circuit labels. All of it flows directly into your certificate. The system handles UK-specific challenges like label strips with handwritten text, symbol icons for showers and cookers, faded markings on older boards, and the various layouts used by different manufacturer
Both Board Vision and Test Vision show a confirmation screen before populating your certificate. You see the detected test type or circuit, the extracted values, and which fields will be updated. If the display was partially obscured or the AI isn't certain about a value, you'll know to check before confirming at your multifunction tester display for high accurate and blazing fast electrical testing and inspection
- Dynamic Pickers
DB location and Circuit destination remembers the last 20 value entered and adds them to the picker list automatically to use next time. Builds yoru own picker list automatically
- Sub Mains
Add sub mains to Db boards that create a tree view for easy visual reference when managing large list of DB baords and Sub mains. Automatically pre fills sub main circuit and details like disconnection time, points served etc
- Quick Fill
Quick Fill has been significantly expanded — now offering over 40 selectable circuit data options for domestic, commercial, and industrial use (up from 6).

12.12.25 12/18/2025
• New: AI Compliance Checker for BS 7671
Introducing iCertifi’s groundbreaking AI Compliance Checker — a fully automated compliance audit powered by advanced artificial intelligence. It analyses your electrical certificates against BS 7671:2018 + A2:2022 in seconds.
It’s not a spell checker. It’s not a calculator. It’s a complete compliance engine that reviews every circuit, every test result, and every value against the actual wiring regulations.
With a single tap, the AI Compliance Checker:
– Scans your entire certificate (supply characteristics, boards, circuits, observations and signatures)
– Validates all test results against BS 7671 requirements
– Identifies non-compliances with precise regulation references
– Generates a clear, professional compliance report showing exactly what needs attention
You’ll instantly see:
– What’s compliant
– What needs review
– What does not meet regulations
• Spark AI: Image Support Added
You can now send images to Spark AI — perfect for querying EICR codes or showing AI an electrical non-compliance rather than describing it.
