Disconnecting a freestanding gas cooker from its flexible hose connection is a task that the Gas Safety (Installation and Use) Regulations permit a competent adult to do in their own home, as it involves breaking a connection rather than making a permanent installation. However, reconnecting the cooker or making any new gas installation must be done by a Gas Safe registered engineer. Understanding the correct procedure ensures the disconnection is done safely.

Important Safety Note

Before disconnecting a gas cooker, confirm that you can turn off the gas supply to the cooker at an isolation valve or at the main meter. If there is no isolation valve at the cooker and the main meter is the only way to turn off the supply, decide whether you are comfortable working with the supply isolated at the meter. If in doubt, use a Gas Safe registered engineer for the disconnection. The Gas Safe Register website provides a search tool to find registered engineers.

Disconnection Procedure

Turn off the gas at the isolation valve beside the cooker, or at the gas meter if there is no local isolation valve. Turn all the burner controls on the cooker to the off position. Wait several minutes to allow any remaining gas in the hose to dissipate. Loosen the nut connecting the flexible cooker connection hose to the bayonet fitting or LPG supply point. The connection is typically a compression fitting nut; use two spanners, one to hold the fitting and one to turn the nut, to avoid twisting the supply pipe. Unscrew the nut and pull the hose free.

Capping the Supply Point

Once the flexible hose is removed, the gas supply point must be made safe. If there is a bayonet fitting at the supply point, it will close automatically when the hose plug is removed. If there is an open-ended pipe fitting rather than a bayonet, a Gas Safe engineer must cap the pipe properly. Do not leave an uncapped pipe end even with the gas supply turned off at the isolation valve; a second line of defence against accidental gas release is always prudent.

The Flexible Hose

The flexible hose connecting a freestanding gas cooker to the supply is a purpose-made cooker connection hose certified for gas use. It must not be made from an unsuitable material, must be approved for the gas type (natural gas or LPG), and must be the correct length to allow the cooker to be pulled forward for cleaning without putting the hose under tension. Using improvised hoses or hoses not rated for gas is dangerous and illegal.

Summary

Disconnecting a gas cooker is legally permitted for a competent adult homeowner. The sequence is: turn off at the isolation valve, turn all burners off, wait, then disconnect the flexible hose. Cap the supply point or use the bayonet fitting. Reconnection must be done by a Gas Safe registered engineer using a new flexible hose. Never leave an open-ended gas pipe uncapped.
