Frequently asked questions
What should an Electrical O&M Manual include?
A complete Electrical O&M Manual typically includes a cover page, document revision record, scope of works, system descriptions, manufacturer datasheets, test certificates, commissioning records, as-built drawings, warranty information, maintenance recommendations and emergency contact details — as covered by this checklist.
Do I need to include electrical test certificates?
Yes. An Electrical O&M Manual should include the relevant test certificates, such as Electrical Installation Certificates (EIC) and Minor Works Certificates, along with commissioning records for systems like emergency lighting and fire alarms.
What's the difference between this checklist and a finished O&M manual?
This checklist helps you gather and organise the right documents. A finished Electrical O&M Manual takes those documents and presents them in a structured, formatted PDF with a cover page, contents page and clear sections — ready to hand over to your client or main contractor.
What if I'm missing some items from this checklist?
Send Project-OM what you have. We'll structure the manual around your available documents and flag anything important that's still missing before the manual is issued.
