Civil Defence NOCs, system certificates and completion

A Civil Defence NOC, a system certificate and a completion certificate cover different stages. Check which document the application requires.

In this guide

Design acceptance, installed-system certificates and the authority’s completion document serve different purposes. Ask who issues the requested document, what it covers and which application depends on it.

Identify the document and its issuer

DCD’s completion application uses “Fire fighting Certificate” for the extinguishing system’s supply, installation and test certificate. It is a supporting system certificate, not DCD’s own completion certificate. The form also asks for certificates for other systems, including the fire alarm and emergency lighting.

Gather the certificate and project references

Gather the actual document title, issuer, project reference, date and stated scope. For an existing property, ask for the available design and completion records rather than relying on a verbal description.

Check the scope and stage

  1. Identify the issuer

    Distinguish an authority document from a contractor or system record.

  2. Identify the stage

    Clarify design, installation, inspection or completion.

  3. Check the scope

    Confirm the building, unit and systems covered.

  4. Check acceptance

    Ask the receiving authority which exact document it requires.

Check the completion document required

DDA’s fit-out completion service asks for a DCD completion certificate. Keep that authority document separate from the system certificates submitted to support it.

Common questions

Is a system certificate the same as DCD completion?

No such equivalence should be assumed. Check the issuer and the receiving authority’s requirement.

Which documents should I keep?

Retain the approved design, relevant system records and authority deliverables with their project references.
