Gas Bayonet fitting

Question

I am having my gas cooker replaced with an electric one. Can I remove the bayonet myself and leave it uncapped, or is this an illegal action. Obviously, I'm not a gas safe registered individual.

Hi Richard
If a gas cooker is no longer to be used then the bayonet fitting must be removed and the pipework capped off accordingly, 
This needs to be carried out by a gas safe registered engineer 
The reason for this is that an uncapped bayonet fitting is classed as an open end , even though it is a spring loaded valve - the valve could possibly fail and cause a gas leak

Paul · Answer

You can remove the cooker hose yourself, but the exposed bayonet fitting needs to capped off as these can allow the gas to escape.

Hello, a bayonet type gas cooker hose can be undone at the bayonet fitting end by anyone provided that it is only a temporary matter. The bayonet is a special fitting which self seals (or is supposed to). This is the whole reason for the bayonet type fitting - it can be easily disconnected by anyone.

If you were dumping the old cooker or replacing it and waiting for a gas safe engineer to connect the new one soon then, yes, you can legally disconnect the bayonet from the bayonet fitting as this will be a temporary matter.

If you are not going to be getting another gas cooker soon then you would need to get a Gas Safe Registered engineer to cap it off correctly and do a tightness test for gas leaks before and after.

A bayonet fitting with nothing connected is not classed as an 'open end' and it is classed as an 'appropriate fitting' for gas  but not appropriate for a long term solution.

An appropriate fitting would be a plug or cap on the gas pipe after removing the bayonet fitting which is classed as 'gas work' and requires gas safe registration.

I would always recommend using  a gas safe Registered engender to test the gas after removal of any appliance  in case the bayonet is leaking

John · Answer

Yes you can. You do not need to be GasSafe to disconnect a bayonet. fitting as it remains sealed.

Damien · Answer

Do not remove the bayonet yourself as it would be an open ended uncapped gas pipe. 
This is advice, nobody can tell you what to do in your own gone but I would recommend not doing this yourself and to get a gas safe engineer in to remove, cap and make safe any work on gas.

Hi,

This would be deemed illegal and you could be prosecuted for such actions. Please Find a gas safe registered engineer to remove the bayonet and test gas.

Kind Regards

Wayne · Answer

You would need a gas engineer to do this type of work.

Pedro · Answer

Hello, 
Any work on gas pipe is illegal to work on unless you are gas safe .  Let alone leaving it uncapped. Very dangerous!

Chris · Answer

Hi
Always use a Gas Safe registered engineer for any gas works. 
You cannot remove bayonet fitting or leave uncapped as there be live Gas in pipework. 
The GSRE removing old gas Hob should disconnect and make installation safe for you by means of removing bayonet fitting and using a compression cap end.
