Check five things before paying: that your scheme provider accepts the app's certificates in writing, which edition of the wiring rules its templates follow, how test results reach the certificate, whether every AI-written or pre-filled value can be seen, edited and switched off, and who holds your data if you cancel. The sign-off stays yours.
The AI is the least important part of the purchase. A certificate's value rests on the edition of the rules it follows, the accuracy of the test figures and your signature. Of the three vendor pages read for this tutorial in October 2026, two name the edition their templates follow and the third says only 'the latest version'. None names a tester that results can be imported from, none states who owns the data you enter and none claims approval by a scheme provider.
What three apps' pages say, and what they leave out
The apps below are the ones whose pages turn up for this search: iCertifi, TradeCert and GetSparky. This is what each page says, read in October 2026, with no vendor prices quoted because they are listed in local currency. Every cell is a claim by the vendor, not a test result.
| Check | iCertifi | TradeCert | GetSparky |
|---|---|---|---|
| Scheme and standard wording | Says its certificates follow a named edition and amendment of the wiring standard; claims no scheme approval, and scheme names appear only in an illustration | Says certificates are 'suitable for' two named scheme providers and client submissions, and aligned with a named edition; claims no formal approval | Says circuits are designed 'strictly in accordance with' the standard and to the latest version; claims no scheme approval |
| Test results | AI reads a photo of the tester's display; 'no cables, no Bluetooth'; names no compatible testers | Lists import of test results and PDFs; names no testers | Test results entered on site in the app; names no testers |
| AI features listed | Board photo to circuit schedule, display reading, a compliance check before sending, and a regulations Q&A | Board photo to circuit data, AI observation wording, notes to certificate fields, and a validation of missed or impossible values | None listed; automated circuit-design calculations |
| Where data lives | On your device or in your own Apple or Google account; ownership not stated | Synced through a major cloud provider; ownership not stated | Stored in the vendor's cloud; ownership not stated |
| Offline use | Certificates and PDFs offline; the AI features need a connection | Certificates completed 'fully offline', then synced | Offline saving, then sync |
| Pricing structure | Free to download; paid plans allow unlimited certificates; no per-certificate fees; a 7-day trial on one plan | Free plan with 200 AI tokens; unwatermarked PDFs need a subscription; 250 monthly AI tokens on the main plan; 'no contract' | Free plan for estimates, invoices and signing others' certificates; paid monthly or yearly plans; a 30-day trial on paid plans |
Read the gaps as a to-do list. No page names a tester that results import from, none states data ownership, and none claims approval by a scheme provider. That doesn't make the apps unsuitable; it means the answers have to come from the vendor in writing before you pay. One page lists eight certificate types for its suite and describes its electrical app as covering three, so check that the types you issue are in the plan you buy. For the wider tool field, seven AI tools for electricians, from calls to certificates puts certificate apps next to the rest.
Scheme and standard: four checks before the AI matters
- Does your scheme provider accept the app's certificates? 'Compliant', 'aligned with' and 'suitable for' are the app maker's words. 'Approved' or 'listed' is the scheme provider's. Ask your scheme provider by email which software or certificate formats it accepts, and keep the reply with your records. If your scheme issues certificates through its own portal, ask whether the app's output uploads to it or has to be typed in again. Double entry cancels most of the time the app was meant to save.
- Which edition and amendment do the templates follow? The rules your certificates are written against change by edition and by amendment, and a template that lags is a template you may have to correct by hand. Open a blank certificate in the trial, find the edition and amendment printed on the form, and compare them with the current ones on the standards body's own page. A vendor that can't tell you when its templates were last updated is a risk in itself.
- How soon after an amendment does the app update, and what happens to certificates in progress? Ask for the update history, and for the policy on drafts started under the old edition. A certificate that spans an update shouldn't change its wording underneath you.
- Are the certificate types you issue in the plan you are buying? Installation certificates, periodic condition reports and minor works certificates are the usual three; EV charging, fire alarm, emergency lighting and solar forms may sit in separate apps or higher plans; one vendor's suite lists them apart from its electrical app. List what you issued last year and tick each one against the plan.
The tutorials on what AI can draft on an installation certificate and what you must sign and what periodic report software and AI can draft and what you decide cover what belongs in the certificate itself. The point here is narrower: whether the template is the right one before the AI touches it.
Test results: how readings reach the certificate
Apps handle test results in three ways, and each fails differently.
| Route | How it works | How it goes wrong | How to catch it |
|---|---|---|---|
| Typed by hand | You enter each reading from the tester's screen | Fatigue and transposed digits late in the day | Read three values back against the screen before you sign |
| AI reads a photo of the display | You photograph the tester; the app reads the number | Misread digits and decimal points; a glare or an unusual layout | Keep the photo with the certificate, and compare three values |
| File or wireless import | The tester sends results to the app | Only some readings arrive, or units and greater-than values are mangled | Compare a full circuit's results with the tester's own memory |
Whichever route an app uses, ask for a live demonstration with your own tester model. 'Works with most testers' isn't an answer, and on the pages read, none of the three names a tester model that results come from. If the route is a photo, ask what the app does with a reading it is unsure of: a flag, a blank or a confident guess. If the route is an import, ask which readings come across. Results that come in several parts for one circuit, such as protective-device tests at different currents, are the likeliest to be dropped.
The failure worth rehearsing is the plausible digit swap. A photo reader sees 0.35 on the display and records 0.53. Both are believable for a lighting circuit, so a rule that flags impossible values stays silent, and the certificate now holds a figure the tester never showed. On a certificate with 60 readings, one swap is easy to miss and doesn't announce itself. The defence is dull: on every certificate, compare three readings against the tester's screen or stored results, picking the highest and lowest values, and keep the tester's own record in the job file. The tutorial on whether ChatGPT can answer electrical code questions safely makes a related point about the regulations Q&A some apps include: it is a lookup aid, not the authority.
AI wording and pre-fills: what you can see, edit and switch off
This is where the advertised AI sits, and where a certificate can quietly stop being yours. Two behaviours need separate checks: pre-filling fields, and drafting wording.
Pre-fills. These are illustrative results from a trial job in which an app read a photo of a 12-way board and filled the circuit schedule, checked against the real board:
| Field | Possible | Correct | Wrong | Filled without being visible |
|---|---|---|---|---|
| Circuit label | 12 | 11 | 1 | 0 |
| Protective device rating | 12 | 10 | 2 | 0 |
| Device type | 12 | 9 | 3 | 0 |
| Cable size | 12 | 0 | 0 | 12, from typical values for the installation type |
| Fields visible on the board | 36 | 30 (83%) | 6 |
Thirty of 36 visible fields right is a useful first draft and a poor final one: six wrong values, each findable only by looking at the real board. The cable size row is the more serious finding. The photo can't show it, so the app filled all 12 from typical values for the installation type, and they now look exactly like readings you took. One vendor's page describes pre-filling 'compliant values' according to installation type. Pre-filling saves typing; it doesn't save inspection. The checks to apply:
- Provenance. Can you tell, on screen and on the PDF, which values were typed, imported, read from a photo or pre-filled? If every value looks alike, a pre-fill becomes a claim you made.
- Required fields. Will the app refuse to issue until a person has confirmed every test value and every field it couldn't see? A button labelled 'validate' that only catches blanks isn't the same thing.
- Switches. Can you turn off each AI feature separately, and does the certificate still work with them off?
- Metering. Where AI is sold in tokens, ask what a typical certificate uses and what happens at zero. If a plan includes 250 tokens a month and a board photo plus wording costs, say, 15, that covers about 16 certificates; ask the vendor to confirm with a real job, because the arithmetic depends on figures the pages don't give.
- Connection. One page says its AI features need a connection even though certificates work offline. A loft or a plant room with no signal means typing.
Drafted wording. Here is a realistic case. The electrician types: 'Junction box in loft has no lid, live parts accessible.' An AI draft comes back: 'Junction box lacks an enclosure and live parts are accessible to touch, contrary to regulation 412.1. Urgent remedial action required.' Two things need fixing. The regulation number is the app's addition, not your finding, and an AI may cite one wrongly: check it against the current edition or delete it. And the severity wording is a classification decision that belongs to you under your report's coding. Ask whether the app lets AI suggest a severity at all, and whether it records the electrician's final choice separately from the draft. A good app shows the AI draft beside your own note, keeps both in the edit history, and never classifies for you.
Records after issue: locks, revisions and signatures
A certificate is a record, and a record that can be edited without a trace is a liability. Four checks that the three pages read did not make clear:
- Locked on issue. Once a certificate is issued, can anyone, including you, change its content without leaving a trace? A good app locks it, and makes any correction a new, numbered revision that keeps the old one.
- Numbering and identity. Does each certificate get a unique reference that survives export, and does the sequence stay intact when you delete a draft? Gaps and duplicates invite questions.
- Signatures. How are the electrician's and the customer's signatures captured and stored, and does your scheme provider or client accept electronic signatures on certificates? Put it in the same email as the acceptance question.
- Several engineers. Ask about separate logins, who can see whose certificates, whether office staff can edit anything after issue, and whether a departing engineer's certificates stay with the firm. One page lists office users as free and charges for each additional user, which makes the role question a pricing question too.
Here is why it matters. A customer queries a certificate issued 14 months ago and says a reading looks wrong. The app's history shows issue on 3 March, one revision on 5 March by the engineer correcting a typo in the address, and nothing since. That answers the question in two minutes. Without a revision history, the only record is a PDF that anyone could have regenerated, and the conversation becomes one person's word against another's.
Who owns the data when you stop paying
The three pages describe three different arrangements: data held on your device or in your own Apple or Google account, data synced through a major cloud provider, and data stored in the vendor's cloud. None states who owns it. The practical questions are what you can get out, in what form, and for how long after you cancel. Send this before subscribing and keep the reply:
Subject: Questions before I subscribe
1. Who owns the certificates and test data I enter? Please point me to the
clause in your terms.
2. Where is it stored, and is any of it used to train an AI model?
3. If I cancel, can I still open, download and reissue past certificates?
For how long?
4. Can I export every certificate as a PDF and every test result as a
spreadsheet? Is there a charge?
5. What happens to my data if you close the service?
6. Which edition and amendment of the wiring rules do your templates follow,
when were they last updated, and how soon after an amendment do you update?
7. Which scheme providers accept your certificates? Can you point me to
their written statement?
8. Which tester models import results? Can you show me one live?
9. Can I switch off each AI feature, and can I see which values were typed,
imported or pre-filled?
Then test the answer. Export ten certificates, open the files on a different device, and check that the PDFs match what the app shows and that the test results arrive as something you can read in a spreadsheet. A client or an insurer may ask for a certificate years after the job; the period you must keep records is for your scheme provider and insurer to say, so ask them, and make sure the app's retention matches or that you keep your own PDFs. The wider question of what a supplier can do with the data you enter is in questions to ask before buying AI that touches client data.
Flat fee, tokens or per certificate: what the structures cost
The three pages show four structures: a flat subscription with unlimited certificates; a free plan that watermarks or limits output; AI metered in tokens; and a free tier that covers other jobs, such as estimates and invoices, while certificates cost money. None of the three charges per certificate on the pages read; if an app you are weighing does, work out the break-even rather than guessing. With illustrative prices of $20 a month for a flat plan and $2 a certificate for a per-certificate app, the break-even is 10 certificates a month. At 25 certificates a month the flat plan costs $20 and the per-certificate one $50; at 6 a month the per-certificate app is cheaper at $12.
Read the trial terms as carefully as the price. A 30-day trial that converts to a yearly plan unless you cancel is a different offer from a 7-day trial that doesn't ask for a card. Ask what the plan costs after the trial and whether cancelling is a button or an email. One page says 'no contract'; that should still be confirmed in the terms before you rely on it. Whether a dedicated app is needed at all, or ChatGPT is enough for the office side, is covered in an AI app for electricians, or is ChatGPT enough.
A trial plan: one finished job, three apps, one afternoon
Pick a job you've already certified, with 10 to 15 circuits and test results you trust. Spend 90 minutes on each app: enter the job, time yourself, note every field the AI pre-filled, check each against the board, and compare the PDF with the certificate you issued. Then apply five gates before you look at price. An app that fails any gate is out. These results are illustrative:
| Gate | App A | App B | App C |
|---|---|---|---|
| 1. Scheme provider confirms acceptance in writing | Pass | Pass | Not answered |
| 2. Templates match the current edition and amendment | Pass | Pass | Pass |
| 3. Pre-fills and AI wording are visible, editable and switchable | Pass | Fail: cable sizes pre-filled with no marker | Pass |
| 4. All certificates export as PDF and results as a spreadsheet | Pass | Pass | Pass |
| 5. Works offline for the whole certificate | Pass | Pass | Pass |
App B fails gate 3 and App C fails gate 1 until the scheme provider replies, which leaves App A. Only now compare speed and price. If the old method took 55 minutes a certificate and App A took 38, that saves 17 minutes. At 25 certificates a month that is 425 minutes, about 7.1 hours; valued at $40 an hour, roughly $283 a month, against a plan of perhaps $20. The saving is an assumption until you time it, and the corrections you made to the AI's draft count as time taken. If App A took 38 minutes only because you skipped checking the pre-fills, the real figure is higher.
Before you sign: six checks that stay with you
No app moves these off your desk. The declaration is yours, so treat every AI-filled field as something you wrote.
- Read every line the AI drafted, aloud if it helps, and delete any regulation reference you haven't checked.
- Compare three test values with the tester's screen or stored results, including the highest and lowest.
- Check the circuit count and labels against the board, and confirm anything the app pre-filled from a photo.
- Confirm the severity of each observation yourself, using your report's own coding.
- Check the limitations, agreed departures and next-inspection date, which are easy to leave at a default.
- Keep the tester's original results and the site photos with the job file, outside the app.
If you'd rather run the trial and the questions with someone, that is what my AI implementation consultation covers: finding the jobs where AI pays off, adding AI to the tools you already use, and handing over something you can run. The contact page has the form.
Questions electricians ask about certificate apps with AI
Can a certificate app sign off the certificate for me?
No. The signature is your declaration that the inspection and tests were done and the results are true, and the app only prints it. AI can draft wording and fill fields, but you have to read and own every line. Treat any AI-filled value as something you wrote, and ask your insurer and scheme provider how they view AI-assisted certificates.
Does the app need to be approved by my scheme provider?
Ask your scheme provider in writing which software or certificate formats it accepts, and keep the reply. Words such as compliant, aligned with and suitable for are the app maker's. Approved or listed is the scheme provider's wording. If your scheme issues certificates through its own portal, check whether the app's output can be uploaded or has to be typed again.
Is photographing the tester's display safe?
It can save typing, but a misread digit does not always trip a validation rule, because 0.35 and 0.53 are both plausible for many circuits. Compare three readings per certificate against the tester's screen or stored results, and keep the tester's own record with the job file. Ask the vendor how it handles decimals and greater-than values.
What happens to my certificates if I cancel?
It depends on the app, and the vendor pages read for this tutorial didn't say. Ask whether you can still open, download and reissue past certificates, for how long, and whether you can export every certificate as a PDF and every test result as a spreadsheet. Test the export on ten certificates before you subscribe, not after you cancel.
Is a free plan enough to start?
It can be for trying the workflow, but read the limits. One app's page says PDFs without watermarks need a subscription and its free plan includes 200 AI tokens; another's free plan covers estimates, invoices and signing certificates others prepared. Use the free tier to run one finished job through, then judge the paid plan on the checks below.
