The certificate is the end of the job, not a second job.
Ohmly writes the EIC, the EICR and the Minor Works certificate from the design, the checklist and the test results it already holds. You check it, sign it and issue it.
Electrical Installation Certificate
New installations, additions and alterations. Carries the design, construction and inspection declarations, the supply characteristics, the schedule of inspections and the schedule of test results.
Electrical Installation Condition Report
Periodic inspection. Observations recorded with their classification codes and carried through to the summary, the extent and limitations, and the overall assessment. Photos added to an observation print on the report, each captioned with the observation's item number and without the camera's location data.
Minor Works Certificate
Work that does not include a new circuit. The short form, filled from the same job record as everything else rather than as a separate exercise.
Where each part of the certificate comes from.
Every part of the certificate comes from something you have already done: the address from the property, the supply details from the start of the job, the circuits from the drawing, the results from your tests and the inspection schedule from the checklist.
Your details, your scheme membership number and your qualification numbers come from your business profile, set once.
On the certificate you issue, a box of the form that Ohmly was not told about prints "Not stated", never as an empty box that could be read as an answer.
Illustrative layout. Ohmly designs its own certificate.
What issuing does, and how it protects you.
Signed on the device, bound to the contents
Your signature is tied to exactly what the certificate said when you signed it. Change a value afterwards and the signature no longer matches, which is what a signature is for.
Numbered from your own register
Certificate numbers come from your issue register, in sequence. They are yours, they do not collide, and they do not repeat. When a customer or an inspector asks for certificate 0092, there is exactly one.
Immutable once issued
An issued certificate cannot be quietly edited. A correction is a new issue that replaces the original, so the original stays exactly as you signed it, which protects you.
Checked the way an inspector will
Before you sign, the inspector preview shows the job read-only, limitations first, then the notices the installation needs and the instruments you used. Anything an assessor would query, you see first.
What Ohmly does, and what stays with you.
Straight answers to what an electrician asks before choosing certificate software.
Works with your scheme
Ohmly’s certificates are set out in a clear layout of Ohmly’s own rather than the IET’s model forms, and list in red anything still missing before you issue. Works with whichever scheme you’re registered with. Your certificate isn’t scheme-branded, and notification stays in your scheme’s own portal.
Every value checked against the book
Every figure Ohmly uses is read from a named edition of BS 7671 or the IET guidance and published sources that go with it, and checked against what is printed. Ohmly gives you the regulation number to look up in the book you already own, and the judgement on site stays yours.
Part P stays in your scheme’s portal
You notify through your own scheme’s portal as you do today, and Ohmly records the scheme, the date and the reference against the job.
You stay in charge
Ohmly does the arithmetic, holds the record and writes the document. The design decisions, the inspection and the declaration are yours, as they should be.
Your certificate questions.
Which certificates does Ohmly generate?
Three: the Electrical Installation Certificate for new installations, additions and alterations, the Electrical Installation Condition Report for periodic inspection, and the Minor Electrical Installation Works Certificate for work that does not include a new circuit.
Which plan are certificates on?
All three are on the free plan, signed and issued, and your first job is free to issue. A job drawn with a Pro or Pro+ wizard needs that plan to issue its certificate. Pro removes the one-job limit and adds your logo. See the plans.
Will my competent person scheme accept it?
Ohmly’s certificates are set out in a clear layout of Ohmly’s own, signed by you on your phone and locked the moment you issue them. Before you issue, Ohmly lists in red anything still missing, and shows you the list again as you issue. Works with whichever scheme you’re registered with. Your certificate isn’t scheme-branded, and notification stays in your scheme’s own portal, just as it does today.
Does Ohmly use the IET model forms?
No. Ohmly lays out its own certificate rather than reproducing the layout of the IET published model forms. The declarations each signatory makes are printed in the model forms' wording.
Can I put my own logo and scheme number on it?
Yes. Your business details, scheme membership number and qualification numbers are set once and carried onto every document you produce, and your logo prints on them with Pro.
Can a certificate be edited after it is issued?
No. An issued certificate is locked. A correction is a new issue that replaces the original, so the original stays exactly as you signed it and your register shows it was replaced.
Where are my issued certificates stored?
On your phone, with the job they belong to. For a second copy, share the PDF somewhere you keep your records, or take a backup file from Settings, which carries every issued certificate. Google Drive backup (Android 12 and later, with a screen lock set) copies the certificate records, but not the issued PDFs.
Does Ohmly handle the EICR observation codes?
Yes. Observations are recorded with their classification and carried through the report. Price each one and, with Pro, Ohmly writes the remedial works quotation for the customer, grouped by urgency, so the report and the next job leave the property together.
Can I record instrument calibration?
Yes. Type the expiry from the calibration certificate, or tell Ohmly how often you have your instruments calibrated, and it reminds you before each one falls due.
Does Ohmly notify Part P work?
No, and it does not need to. You notify in your own scheme’s portal as you do today, and Ohmly records the scheme, the date and the reference against the job.
