iCertifi vs NAPIT FastTest
NAPIT FastTest is scheme software with metered AI credits, and notification is tied to NAPIT membership. iCertifi is the app voted #1 by electricians in the TradeSkills4U survey in Professional Electrician & Installer – four AI tools, a professional cable calculator, native Apple security and five trades, whichever scheme you are with.
Quick answer
iCertifi is voted #1 by electricians in the TradeSkills4U survey in Professional Electrician & Installer, with Board Vision, Test Vision, Spark AI, Certificate Guardian and Circuit Designer. NAPIT FastTest is the scheme’s own cloud software – fine if you are NAPIT-registered, but its AI is metered by credit and notification is built around NAPIT membership. iCertifi works whichever scheme you are with and keeps your data on your device.

Working across every scheme, not inside one
A full AI engine vs no AI: Board Vision, Test Vision, Spark AI and Certificate Guardian scan the board, read the meter, answer the regs and check compliance. FastTest has none of this.
Not tied to one scheme: iCertifi works whether you are with NICEIC, NAPIT, ELECSA or SELECT, and your certificates go with you if you switch. FastTest is built around NAPIT.
A professional cable calculator built in: Circuit Designer sizes the cable, calculates volt drop and Zs and pushes the circuit onto the certificate. FastTest has no equivalent.
On-device, every trade, and it invoices: data stays on your device, gas (CP12) and PAT join fire and emergency lighting, and Mintbooks turns each certificate into a Making Tax Digital invoice. FastTest does not advertise invoicing.
What FastTest asks you to give up
Metered AI: 200 credits are included with a licence, then 2p per additional circuit generated.
Built around one scheme: oriented to NAPIT rather than working freely across every scheme provider.
Licensed per seat: one Windows and two mobile licences. iCertifi adds Gas, PAT, invoicing and an Apple Watch app.
Which one fits your setup
If you are a committed NAPIT member and want the scheme’s own tool, FastTest does the job. But its AI is metered by credit and notification ties you to one scheme. iCertifi works with any scheme, adds a full AI engine and Circuit Designer, keeps data on-device, invoices the job and covers five trades. It is the app voted #1 by electricians in the TradeSkills4U survey in Professional Electrician & Installer.
NAPIT FastTest questions electricians ask
Can I use iCertifi if I am NAPIT registered?
Yes – iCertifi produces BS 7671 compliant certificates and works whichever scheme you are with, including NAPIT, NICEIC, ELECSA and SELECT.
Is NAPIT FastTest better than iCertifi?
No. FastTest is scheme software with metered AI credits, and its notification is oriented to one scheme. iCertifi has a full AI engine, Circuit Designer, native Apple security and five trades.
Does iCertifi work offline?
Yes – the standard app works fully offline on-device, and Cloud Pro adds encrypted cloud sync when you want it. FastTest is cloud-based.
Can I use iCertifi while I am NAPIT registered?
Yes. NAPIT scheme rules require certificates that comply with BS 7671, not a particular piece of software. iCertifi produces BS 7671 compliant certificates in the standard model forms, and the same certificates suit NICEIC, ELECSA or SELECT if you ever change scheme. Always check your scheme’s current requirements.
Does NAPIT FastTest have AI?
Yes – NAPIT sells AI Integration with a monthly credit allowance and AI boards and circuits. The difference is depth and metering: iCertifi’s AI is unmetered and covers board scanning, meter reading, a BS 7671 and BS 5839 regs assistant, and a full compliance check before you sign.
