Purpose and Procedure for Drafting the Document
What Is a Gas Tightness Test Certificate?
A gas tightness test certificate is a formal document that provides evidence that a gas system has been tested for leaks and meets the required standards. It records the test pressure, duration, pressure drop, and pass/fail result.
Who Uses This Template?
This template is used by Gas Safe registered engineers to certify the integrity of gas pipework after installation, repair, or modification. It may also be required by building owners or regulatory bodies as proof of compliance.
Key Features
The template includes sections for test details, system information, equipment used, observations, and signatures. It also requires photo evidence of the pressure gauge reading and test equipment setup.
New Gas Installation
After installing new gas pipework, this certificate confirms that the system is gas-tight and safe to use.
Gas Repair or Modification
Following a repair or modification to existing gas pipework, a tightness test is required to ensure no leaks were introduced.
Pre-Commissioning
Before commissioning a gas appliance or system, this certificate provides documented proof that the pipework holds pressure.
Compliance Documentation
The certificate may be submitted to building control, insurance companies, or gas network operators as part of compliance records.
- 1
Isolate System
Isolate the gas system and ensure all appliances are turned off.
- 2
Connect Test Equipment
Connect the pressure test equipment to the system and pressurize to the required test pressure.
- 3
Hold Pressure and Monitor
Hold the pressure for the specified duration and monitor for any pressure drop.
- 4
Complete Certificate
If the test passes, release pressure, reconnect the system, and complete the Gas Tightness Test Certificate with all details and signatures.
Photo Report Generator

Frequently Asked Questions about Photo Reports and Photo Tables
What is a gas tightness test?
A gas tightness test is a pressure test performed on gas pipework to check for leaks. The system is pressurized to a specified level and held for a set duration; if the pressure drop is within acceptable limits, the test passes.
Who can perform a gas tightness test?
Only a Gas Safe registered engineer should perform a gas tightness test. The engineer is responsible for conducting the test correctly and completing the certificate.
What information is recorded on the certificate?
The certificate records the test date, test pressure, duration, pressure drop, pass/fail result, system description, installation location, equipment details, observations, and signatures of the engineer and witness.
Is a witness signature required?
A witness signature is optional but recommended. The witness may be the property owner, contractor, or another engineer. The engineer's signature is mandatory.
How does this certificate differ from a Gas Pressure Test Record?
Both documents record pressure test results, but the Gas Tightness Test Certificate is specifically for tightness tests after installation or repair, while the Gas Pressure Test Record may include other types of pressure tests (e.g., strength tests) and is more general.
