Minor Works Certificate App
Finish a Minor Electrical Installation Works Certificate in a few minutes on your phone — describe the work, add circuit details and test results, then sign and send.

Minor Works certificates in minutes
Adding a socket, moving a light or fitting a spur is quick work — the certificate should be too. AiCert° gives you a short, focused Minor Electrical Installation Works Certificate you can complete on your phone before you leave the property, so small jobs do not turn into late-night admin.
Describe the work, confirm the circuit it is on, record the protective device and conductor sizes, enter your test results and sign. The customer gets a professional PDF straight away, and you get your evening back.
What the Minor Works app includes
- A clear description of work section, with AI help turning your notes into tidy wording.
- Circuit details: circuit type, conductor sizes, protective device and supply.
- Test results for continuity, insulation resistance, polarity, Zs and RCD operation.
- Customer and address filled in from the job automatically.
- Sign on screen and send the certificate to the customer by email.
- Every certificate stored against the job and property for future reference.
Small jobs, properly paid
Minor works are often the jobs where invoices slip through the cracks. Because the certificate lives on the job in AiCert°, you can go straight from signing to raising the invoice and recording the payment. At the end of the month you can see how much those small jobs really brought in.
Each Minor Works certificate costs £1 to issue. There is no monthly fee on the Free plan, so you only pay when you actually do the work.
Know when to use an EIC instead
A Minor Works certificate is for additions and alterations that do not include a new circuit. If the job includes a new circuit or a consumer unit change, use the Electrical Installation Certificate instead — both are available in the same app, and you can switch between them without re-entering the job details.
As with every certificate in AiCert°, AI only helps with the typing. You carry out the tests, check the results and sign the certificate yourself.
