Say what you found and Modyx writes it up, codes it to BS 7671, and cites the regulation. You read it, change anything you disagree with, and sign. The certificate is finished and issuable — nothing to retype into anything else.
How many of these do you do a week?
£639 and 14h 12min a month, lost to paperwork.*

First 5 certificates free · then £39/month · cancel any time
Your first 5 certificates are free. After that it's £39 a month — one plan, no tiers, no credits, no per-certificate charges. Unlimited certificates, quotes and invoices, and you can cancel any time. That's the whole price list.
When you sign your 6th certificate — not on a date, and not on a timer. Your first 5 are free, so the bill starts when the product has already done 5 real jobs for you. There's no clock ticking down while you're having a quiet fortnight. We email you the moment your free run is used up, and the app asks you to confirm before it signs the one that starts the £39. No surprise charge, ever. Start your 5 free certs.
You're not paying anything today — the card is stored, not charged. Your first 5 certificates are free, on your own real jobs, and that's where you find out whether it holds up: the finished, issuable PDF is delivered every time, coded to BS 7671, from the very first one. We email you the moment the free run is used up, and the app asks you to confirm before the certificate that starts the £39. Cancel any time before then and you've paid nothing. Start your 5 free certs.
So that nothing interrupts you later. The alternative is a paywall that slams down mid-job — you're in someone's loft at half four on a Friday, you sign your sixth cert, and the app asks for a card. We'd rather take it up front, charge you nothing, and let the 5 free ones run. It's a card on file, not a payment: nothing moves until you've used your free run, we email you before it does, and you cancel in two clicks any time.
10, and then the same £39 kicks in — same as the certs, and the same email warns you first. It works out at about two per job, so it lands at roughly the same time as your fifth free certificate. It's there to stop the free run being used as a permanent invoicing app, not to catch you out. Once you're subscribed there's no limit at all.
Yes. Unlimited certificates, quotes and invoices, for one working electrician. We don't throttle you, meter you, or cut you off for doing a lot of certificates — do forty in a month and you pay £39, same as everyone. Fair use here means abuse: sharing one login across several people, running it through automation, or reselling it. It has never meant volume. The one honest caveat: if you're doing serious numbers we might drop you a line to check Modyx is keeping up. That's a conversation, not a cap, and it isn't a bill.
Yes — every one, from the first. It's the standard form, filled in and coded, as a finished PDF signed under your own name and reg number. No watermark, no "DRAFT" stamped across it, nothing held back until you pay, and nothing to retype into another system. You send it to the landlord or the letting agent like any other cert.
Your signature and your registration number are what certify a cert. That's what transfers the liability, and it's been true of every certificate you've ever issued, whatever software drew the form. Modyx fills the form in; you certify it. You stay the duty-holder, and nothing goes out that you haven't read and signed.
No, and you shouldn't. You review every observation, every code and every test value before you sign, and you can change any of them — "make obs 3 a C3" takes five seconds. Modyx codes against BS 7671 and Best Practice Guide 4 and cites the regulation on every line, so checking is quick, and it flags borderline readings rather than quietly waving them through. The judgment is yours.
No. Quotes and invoices are included in the £39 — no separate charge, no separate bill, and once you're subscribed no limit either. Dictate as many as the job needs. It's the paperwork around the job, in the same app, on the same plan. (During your free run there's a cap of 10 — see above.)
You can cancel any time, online, in two clicks — no contract, no notice period, no phone call. The certificates you've already signed are yours. They're finished PDFs: you've issued them to the client, and cancelling a subscription doesn't reach back and take a signed cert off you.
Keep dictating. If there's no signal, the note is saved on your phone and sent the moment you're back in range — you'll see it sitting there marked as waiting, and it goes on its own. Nothing you say is ever lost to a dead bar. The one honest caveat: the coding happens on our servers, so you won't see the written-up observation until it's uploaded. In a cellar you talk; in the van it catches up.
Talk the job through and the coded cert lands in the app in minutes — observations classified, schedule built. You read it over and sign it. That's the cert issued.
EICR, EIC, Minor Works and RAMS — plus the quote and the invoice around the job, in the same app.
Read them out as you go, import the CSV from your tester, or photograph the schedule. Modyx puts the readings into the schedule of test results and flags anything out of range for you to look at.
It's built on voice notes from real jobs — van noise, regional accents, "consumer unit" said six different ways. If something material is missing it asks you one question, then gets out of your way.
Sign up here on the web — that's where your account, your card and your plan live. Then download the iOS app, which is free, sign in, and talk your next job into it. No desktop software, no portal, no instrument export.
Your account and your certificates live on servers in the EU (Amsterdam), encrypted at rest. They are never sold and never used to train AI models. Being straight with you about one thing: to turn your voice into a cert, the recording goes to our transcription provider and the text to Anthropic — both US companies, both contractually barred from training on it. Share links expire after 72 hours, and if you ask us to delete your data it's gone. It's all set out plainly in our privacy policy.
Walk the job, talk it through, read the draft over and sign. That’s the whole workflow.
