When does commissioning happen?

After the system is installed. The DNO needs the commissioning paperwork to close out the connection.

What do I need to provide?

The install date, commissioning test sheets, photos and details of any equipment changes.

Yes. DNOs expect commissioning documents shortly after installation, typically within 28 days.

What if the installed equipment differs from the approval?

Tell us before submitting. We'll check whether the DNO needs to be informed of the change.
