Disconnect gas meters and regulators

Business Sectors (Suites): Gas Network Construction Operations
Developed by: Energy & Utility Skills
Approved on: 01 Mar 2023


​This standard is about disconnecting gas meters and regulators.  Meters can:

  • be credit, prepayment diaphragm or ultrasonic
  • have a capacity of 2.5 to 16.0m3/hr
  • be low pressure up to 75mbar or medium pressure from 75mbar to 2bar (4bar in Northern Ireland).

This standard covers all aspects of disconnecting gas meters and regulators and can apply to any type of fuel gas or combinations of fuel gas including, but not restricted to, natural gas, LPG, blended or 100% hydrogen.
This standard is for gas network construction service layers who are also required to carry out meter disconnections. 

Performance criteria

You must be able to:

​1. Make sure all required pre-work checks have been carried out prior to starting disconnection activities

2. Check that conditions within gas and earthing systems will permit safe disconnection 
3. Select and use the correct tools, test equipment and other equipment for all aspects of the work
4. Use designated safe isolation methods, tests, fittings and procedures to disconnect gas and earthing systems and components
5. Take precautionary actions to ensure that temporarily disconnected meters do not present a safety hazard
6. Minimise damage to customer property and building features throughout all stages of work
7. Disconnect and remove any decommissioned gas meters with a capacity from 2.5 to 16.0m3/hr, regulators, gas systems and components, and earthing system components in current use in line with disconnection plans 
8. Mark any live gas pipes with a notice to indicate they contain gas
9. Complete all relevant documentation and paperwork in line with industry standards
10. Resolve problems within own area of responsibility and competence in accordance with approved procedures
