How do I turn off my gas supply?

If you’ve gas at home, it’s important to know how to turn it off in case of an emergency.  

How to turn off your gas supply

As soon as you move in or have gas installed for the first time, you should know how to turn off your gas supply at the safety isolation point. 

Your builder or gas installer should provide you with a 'Conformance Declaration' for your gas installation. This document contains important safety information, including the location of your safety shut off valve for use in the event of a domestic emergency or gas leakage. 

The shut off is frequently fitted within your meter box, outside the house. If you require a meter key or if the gas shut off valve is hard to reach or won’t  operate, call Gas Networks Ireland on 1800 464 464.

It’s advised to turn off the gas when you go away on holidays, or leave your home unoccupied for any length of time. 

  1. Firstly, turn off your gas appliance taps and any pilot lights.  
  2. Then turn the safety shut off valve to the off position. It's 'off' when the lever is at right angles to the pipe. 

How to turn your gas supply back on 

Ensure that all your gas appliance taps and pilot lights are turned off, then simply return the safety shut off valve to the 'on' position. 

  • It's 'on' when the lever is in line with the pipe. 
  • Then re-light any pilot lights following the manufacturer's instructions for each appliance.
