Public Consultation on I.S. 820 Non-domestic Gas Installations


I.S. 820 – Non-domestic Gas Installations – (Edition 3)
The enquiry will last from the 10th April until the 22nd May 2018.

This Standard specifies the requirements for natural gas and liquified petroleum gas (LPG) installations in commercial and public access buildings, outdoor catering, mobile catering and display units at maximum operating pressures not exceeding 5 bar and industrial gas installations at maximum operating pressures not exceeding 0,5 bar, from the point of delivery up to and including the appliance(s) in these non-domestic premises.
The requirements include:
  • the design, construction and testing of pipework, pipework ancillaries and meters for new installations as well as to replace parts of, or extensions to existing installation pipework;
  • purging of air from, and the admission of gas to, pipework installations and handover to the operator/duty holder;
  • the installation and commissioning of appliances;
  • the safe operation and maintenance of installations in use.

Edition 2 of this standard was published in 2010.
Since then, the CRU has advised that the current Registered Gas Installer (RGI) regulatory model, which governs the work of RGIs in the domestic sphere, will be extended to those works on Natural Gas and LPG fittings designed to be used by Non-Domestic gas customers. This will make it a legal requirement for Non-Domestic Gas Works to be carried out by a Non-Domestic RGI only.
In light of this, I.S. 820, which will be referenced in supporting legislation, has been revised by the subcommittee, TC2 "Installations and Appliances" of the Gas Technical Standards Committee to reflect the new provisions.
Included in the new provisions, are the requirements for LPG outdoor catering, mobile catering and display.
