A workmanship warranty is your own guarantee that the labor is defect-free — the terminations and grounding you made, the breakers and devices you seated, and the way the circuit was wired to code. A manufacturer warranty covers the panel, breaker, or device itself and is issued by the brand, not the electrician. This certificate states your labor guarantee and passes through the manufacturer's parts coverage so the customer sees both in one place.

Most contractors guarantee their workmanship for about one year, while the manufacturer parts warranty on installed equipment often runs 10 years. Both clocks start on the completion or installation date, not the purchase date — so this certificate records that date and calculates each expiry from it.

Overloading circuits, DIY or third-party alterations to the installed work, misuse, and damage from lightning, floods, or utility power surges all void electrical workmanship coverage. Manufacturer-defect devices are routed to the product warranty rather than your labor guarantee, and unregistered equipment may carry only its base parts term.

Usually not — a contractor workmanship warranty is written for the original customer and this template is non-transferable by default, voiding if the property changes hands. Some manufacturer parts warranties allow a one-time transfer to a new owner within a set window, but that is separate from your labor guarantee. Edit the terms if you choose to offer transfer.

The customer contacts you in writing — using the phone or email on the certificate — within 30 days of noticing a defect, and includes the certificate number, the original invoice, and photos. You must be given a reasonable opportunity to inspect and remedy the issue before anyone else is hired. The claim process field spells this out so expectations are clear up front.
