What to Expect When Hiring a Gasfitter in Christchurch

The Process: Step by Step

1. 1

   Describe the Job or Issue

   Contact the gasfitter with details about the work needed — new appliance installation, repair, or gas leak concern. Mention the gas type (natural gas or LPG) and the specific appliance brand if relevant. For gas leaks, call immediately and ventilate the area.

2. 2

   Site Assessment

   The gasfitter inspects the site, checks existing gas pipework and connections, and assesses ventilation requirements. For new appliance installations, they confirm the gas supply is adequate and pipework is correctly sized.

3. 3

   Quote & Appliance Selection

   You receive a quote covering labour, materials, the Gas Safety Certificate, and any consent costs. If a new appliance is needed, the gasfitter may recommend specific brands and models suited to your requirements.

4. 4

   Gas Work

   The gasfitter installs, repairs, or services the gas system. This may involve new pipework, appliance connection, regulator installation, and ventilation modifications. The gas supply may be temporarily shut off during the work.

5. 5

   Pressure Testing & Safety Checks

   After completing the work, the gasfitter pressure-tests the entire gas system to check for leaks. They test appliance operation, check ventilation adequacy, and verify carbon monoxide levels to ensure everything is safe.

6. 6

   Gas Safety Certificate & Handover

   The certifying gasfitter issues a Gas Safety Certificate confirming the work complies with NZ regulations. They explain the operation of any new appliances, provide maintenance advice, and clean up the work area. Keep the certificate for your records.
