Purpose and Procedure for Drafting the Document

What Is a Gas Pre-Commissioning Inspection Report?

This report documents the inspection of a gas installation before commissioning, verifying that tightness tests pass, appliances are correctly installed, and ventilation is adequate.

Why Use This Template?

The online template ensures all pre-commissioning checks are documented, including tightness test parameters, appliance conditions, and ventilation status. It provides a clear readiness assessment.

Key Sections

Sections include inspection details, tightness test, appliance checks (repeatable), ventilation check, conclusions, and signatures.

New Gas Installation

After a new gas installation is completed, the pre-commissioning inspection verifies it is safe to proceed with commissioning.

Major Modification

When significant changes are made to an existing gas system, this inspection ensures the work meets safety standards before recommissioning.

Quality Assurance

Contractors and gas engineers use this report to document that all pre-commissioning steps have been completed satisfactorily.

  1. 1

    Perform Tightness Test

    Conduct a gas tightness test on the installation pipework, recording test pressure, duration, pressure drop, and result.

  2. 2

    Check Appliances and Ventilation

    Inspect each gas appliance for condition and verify that ventilation is adequate for safe operation.

  3. 3

    Assess Readiness

    Provide an overall status indicating whether the installation is ready for commissioning, and list any recommendations.

Frequently Asked Questions about Photo Reports and Photo Tables

Who performs a pre-commissioning inspection?

A Gas Safe registered engineer typically performs the inspection. The installer may also be present and sign the report.

What is included in the tightness test?

The tightness test measures the pressure applied, test duration, pressure drop, and whether the test passed or failed. It ensures there are no gas leaks.

Can I add photos to the report?

Yes, the template supports attaching photos of new pipework, appliance connections, and tightness test equipment.

What happens if the installation is not ready?

If the overall status is 'Not Ready', the report includes recommendations for remedial work that must be completed before commissioning.

How do I use this template?

Open the template in the online editor, fill in the inspection details, record tightness test results, check appliances and ventilation, and sign digitally. Export the completed report.
