You will require this approval if you are undertaking any gas installation work. There are three types of gas installations, standard, prescribed and complex. The gas installation type is defined largely by the class of building into which the gas installation is being located. For a thorough description of the types of installations please refer to the Agency website.
Any individual gas appliances being fitted as part of the gas installation must also be approved by the Agency. The gas-fitter carrying out the gas installation must complete a Gas Fitting Notice (Certificate of Compliance), which certifies that the installation has been carried out in accordance with any relevant standards.
Please consult the Contact Officer for more information.
