It is not only an electrical certificates app. It helps you run the business.
Certificates are the job. Clients, retests, reminders and invoices are the business. iCertifi keeps all of it in one place, and hands the rest to the apps you already use.
Client Hub
Every client, their certificates, their retest dates and your notes on one card. The list builds itself as you send certificates out.
Retest reminders
Every next inspection date is watched. iCertifi shows who is overdue and who is due soon, and writes the reminder for you to read and send.
Invoicing
Finish the certificate and the draft invoice is waiting in Mint Books, priced from your own price list. Nobody types the job out twice.
Talks to your other apps
Mint Books, Verifi, your Calendar, your Contacts, Dropbox and the other iCertifi apps on your device.
Your competition is still typing. You’re already done.
From the consumer unit to the next booking, every step of the job happens in one app. Tap a step to see how it works.
Bring them back
Client Hub and Retests due tell you who to remind before their certificate runs out.
However the circuit data exists, Board Vision finds it
Photograph a distribution board, a printed or handwritten schedule, or scan a PDF certificate. Board Vision reads it, builds the circuit schedule and shows you everything before anything goes onto your certificate.
Three ways to scan
Scan Whole DB Board
One photo of the board: every way, device and rating, including 3-phase TP&N boards.
Single Circuit
Add or check one circuit at a time without rescanning the board.
Hand Written Or Printed Schedule
Bring in the schedule from an old paper or PDF certificate. Scan Another Sheet when it runs over more than one page.
- Reads MCBs, RCBOs, AFDDs, RCDs, SPDs, fuses and main switches, with their ratings
- 3-phase TP&N boards with L1, L2 and L3 worked out automatically
- Scan a PDF certificate and its circuit data comes straight in
- Warns you if the photo is blurry, too dark or has glare, or does not show a board, so you can retake it
Photograph
Frame the board or the schedule, crop to what matters and tap Crop & Scan.
Review
Every circuit, device, rating and phase on the full screen Review Scan. Change anything before you import.
Import
The circuit schedule fills in on your certificate, with L1, L2 and L3 printed where they apply.
Watch Board Vision scan a real board
See a consumer unit go from one photo to a filled circuit schedule in iCertifi.
Test Vision: point the camera at the tester and the reading lands in the right box
Photograph your multifunction tester’s display. Test Vision recognises the test you are doing, reads the value and fills your certificate. Works with any test instrument: no cables, no pairing, no manufacturer software.
- Camera buttons on Continuity, Insulation resistance, Zs and RCD results
- Scan one result after another, then Add All Results to the circuit in one tap
- A confirmation screen shows every value, how confident the reading is (high, medium or low) and the box it will fill, before anything is added
Circuit details and test results: tap Ring and the circuit fills itself
The circuit page shows circuit details and test results together, or one half at a time. What you need is on the page, not hidden in a menu.
- Quick Fill bar: Ring, Radial, Lights, Cooker, Shower, Immersion, Smoke, Boiler, Spare, EV charger, Garage, your own saved circuit, and More with over 50 domestic, commercial, industrial and sub-main options
- A camera button on each test result scans your tester straight into the right box
- Test Logic speaks on the page: an out of range reading turns red or amber with a short explanation and what to do next
- On a TT installation, a reminder that every circuit needs an RCD (Regulation 411.5.2) when no RCD is entered
- The Circuit Assistant menu: Copy Circuit, Paste Circuit, Save Circuit As Template, and Mark circuit as complete
Digital schedule of test results: turn your device sideways and the board becomes a spreadsheet
No more paper EICR test sheets. One row per circuit and every column the schedule prints, with the same pick lists as the circuit page. Return moves down the column and skips spare ways.
- No. and designation stay put while you scroll sideways
- L1, L2 and L3 rows are tinted, and out of range readings are coloured by the same rules as the circuit page
- N/A, Lim and Clear sit on the keyboard bar
- Turn back and the circuit page shows what you typed. Detailed View on the board page opens the same grid
- Add a circuit, a 3 phase circuit or group, several at once, a spare, a submain, a template, Pre Filled Circuits, Board Vision or Design Circuit from one menu
Automatic DB schematic: see what feeds what
On any certificate with two or more boards, iCertifi draws the distribution diagram for you: the supply, every board and the board that feeds it, on its own PDF page.
- Drawn from each board’s Supplied from box, so there is nothing new to fill in
- Supply device and cable size on every line, with main switch, Zs, Ipf and circuit count on every board
- Blank or unmatched links show as dashed lines, never guessed
- Check board links spots boards fed from a circuit called DB10 Supply and asks before filling it in
- EICR, EIC, Domestic EIC and EV Charger. Turn on Board Diagram in Settings, or per certificate from the cog menu
Certificates from another app? Import the PDF
Moving to iCertifi, or taking over a job another firm certified? Import PDF reads a certificate made in another app or software and turns it into an iCertifi certificate for you to check and finish.
- Tap the cog in Saved Certificates, then Import PDF. Save the PDF to Files first, then choose it
- Copies the client and installation details, the supply details, and every board, circuit and test reading on the schedule
- Make it an EICR, EIC, Domestic EIC or Minor Works
- Any reading the PDF gave two different answers for is shown for you to pick or type before anything is imported
- Tick boxes, observations, the earthing type and the overall result are not copied, so you fill those in yourself
- Your first 10 imports are free, whatever their size. After that each circuit uses 1 AI token, the same as BoardVision
From EICR observation to the repair certificate
Coded a C1, C2, C3 or FI on an EICR? Tap Certificate for this repair on the observation and choose the certificate the work needs. The new certificate starts filled in from the EICR.
- Minor Works for a repair or change to one circuit. Pick the circuit and its details come across
- EIC or Domestic EIC for a new consumer unit, new circuits or a rewire. For a consumer unit change, copy the boards and circuits (names, cables and wiring) or start with an empty board
- The client, address, contractor, supply and earthing details come from the EICR, with a description of the work taken from the observation
- Test results, protective devices, dates and signatures are left blank for the work you have not done yet
- The EICR is not changed. The new certificate is waiting in Saved Certificates
An EICR app with photo evidence: a picture tells a thousand words
iCertifi is EICR software on your iPhone and iPad. Code every observation C1, C2, C3 or FI and attach the photos straight from the job. Your customer sees the evidence in the report, and you keep a complete, defendable record.
