Completion Certificate (>=50kVA)

The Irish Electrical Completion Certificate (No. 2) is the equivalent of the No. 1 certificate for larger installations with a supply capacity at or above 50kVA, typically covering commercial, industrial, and large-scale developments. In addition to the standard installation details and circuit schedule, it captures supply capacity, maximum demand, and main distribution board details. It certifies compliance with I.S. 10101 and must be issued by a Safe Electric registered contractor. CertBox produces the supporting test record; the Completion Certificate itself must be issued on the numbered form supplied by Safe Electric.

I.S. 10101:2020 (National Rules for Electrical Installations, as amended by A1:2024), S.I. 256 of 2007, Safe Electric schemeValid: No fixed expiry — attached to the installation

Frequently asked questions about Completion Certificate No. 2

What installations require a Completion Certificate No. 2?
A No. 2 certificate is required for installations with a supply capacity of 50kVA or above — typically commercial units, office buildings, industrial premises, and large residential developments with a three-phase supply. Domestic properties almost always use the No. 1 certificate.
Do I need to declare maximum demand on a No. 2 certificate?
Yes. The maximum demand (kVA) is required on a No. 2 certificate to confirm the installation has been designed to handle the anticipated load. This is particularly important for commercial installations where diversity factors and future load growth must be considered.
Can the same Safe Electric contractor issue both No. 1 and No. 2 certificates?
Yes, provided the contractor holds the appropriate Safe Electric classification for the type of work. Some contractors are registered for domestic work only, while others hold authorisation for commercial and industrial installations.
