One job. Six stages. Entered once.
Follow a consumer unit change on a three-bedroom semi, from the first question to the signed certificate. You enter each detail once, and Ohmly carries it through to every document.
Add the job
Pick the job type: a ring final, a lighting circuit, a shower, an EV charger, a three-phase board and more, and on Pro+ a consumer unit replacement workflow.
Then answer a few simple questions about the supply, the earthing and the circuits going back in. Ohmly asks only what this job needs.
The circuits are built
Ohmly draws every circuit from your answers, using a consistent symbol set and BS 7671 conductor colours, and chooses the cable sizes, protective devices and RCDs as it goes.
The drawing shows you, and whoever works on the installation next, exactly what is there. When plans change on the day, add to it and Ohmly checks the change live: green when the circuit is complete, amber when something is missing, red when it will not work.
A lighting circuit with two-way switching. Conductor colours to BS 7671; black and grey are the strappers.
The checks run
Every check is made against this design, on this supply, in this location, not against a generic template.
Where Ohmly needs something you have not told it, it asks for it by name rather than guessing.
Materials and quote
Ohmly generates the quote from the job you set up by answering a few simple questions: every cable, accessory and protective device counted for you and priced at your own rates, with your day rate, markup and VAT. Anything Ohmly holds no price for is listed on the quote as not included in the price, so the customer can see what the total leaves out.
You look it over and send the customer quote the same day, while they still remember you. Priced materials and the customer quote are Pro.
No VAT is charged on this quotation. Figures are illustrative. Ohmly prices against the rates you set.
Checklist and tests
Safe isolation comes first, as recorded steps, then an installation checklist made for the work in front of you.
Each reading is recorded once and checked against the value your design expects as you go, so a problem shows up while you are still at the board. Every result goes straight onto the certificate.
The certificate
Everything above is already on the certificate: the installation details, the supply, the inspections, the test results and the circuits.
Check it, sign it on your phone and issue it, numbered from your own register and locked once issued. Before you sign, the inspector preview shows you the job the way an assessor will read it.
You can send the customer a plain-English summary alongside it. On a condition report, price each observation and, with Pro, Ohmly writes the remedial works quotation too.

What you keep after the job.
The next job, already yours
Your customer keeps the certificates and a plain-English summary you can send them, carrying your business name and contact details, and your logo on the certificates with Pro. When they need an electrician again, years from now or after the house has changed hands, the paperwork in the drawer points straight to you.
The next inspection, not forgotten
On Pro+, every job is held against the property, and Ohmly reminds you when an inspection falls due, so the customer hears from you first.
Your instrument dates, looked after
Ohmly reminds you before each instrument is due for calibration, on your own interval. Free on every plan.
The next similar job, started
Duplicate a finished job or save it as a template, so repeat work starts from the last one.
Three ways into the same six stages.
Most work is a change to something already installed, so Ohmly is built for that as much as for new work.
New circuit
Designing from scratch. Answer the questions and Ohmly takes it from there.
Add to existing
Describe what is already there and draw your change on top, so the diagram shows old and new. Putting right what an inspection found starts here too, and the record shows what was done about each observation.
Condition report
Inspect a whole installation, board first, and Ohmly steers the paperwork to an EICR at the end.
Learning and quick answers are built in, and they are free. Lessons, practice questions that show where each answer comes from, a glossary, the symbol library, a safe isolation reference and calculators including “Which RCD do I need?” are all inside the app, so they work in a basement with no signal. Ohmly gives you the regulation number to look up in the book you already own.
