    Gas cookers and gas hobs have 2 very different ways of connecting to the gas supply.


    First the Gas cookers, they have to be connected via a flexible gas pipe into a bayonet. 

    The gas hobs have to be connected into the supply via rigid pipe and not by a flexible pipe into a bayonet.

    Over the last 12 months we have been to many properties to carry out landlords gas safety inspection

    We found that the gas hobs has been connected to the gas with a flexible pipe. 

    This is against the gas regulations and as such we had to disconnect the gas hob. 

    Most of the customers asked us to reconnect the gas supply the correct way, which we did.

    With a gas hobs, the supply pipe needs to be clipped to the wall for support, and a gas valve fitted.

    So the hob can be isolated if repairs need to be carried out, 

    without switching off the whole supply within the property. 

    The pipework should be in copper and must not be in plastic.

    With the gas cookers, when you purchase from your local store they don’t come ready to plugin like some of the salesmen may tell you. 

    The Gas cooker needs a fixing kit for the correct installation. 

    The kit consists of a gas cooker flexible hose pipe, bayonet if needed, and a stability bracket or chain.

    As with any gas works, only a gas safe registered engineer can carry out the installation of gas cookers or gas hobs, and you should not try to do it yourself.

    When you call in the local gas safe installer, the first thing he will do is to carry out a gas tightness test, this is to make sure there is no gas leaks in the property. 

    The test takes 4 minutes to complete. 

    First they do a let by test, this is to see if the gas meter is letting gas pass the emergency control valve, then on to a stability test, this is to let the gas settle, then on to check for leakage. 

    If no leakage is found then the installation can go ahead.

    With gas cookers, the first thing is to make sure the gas off, if a bayonet is needed then the pipe will be cut and clipped to the wall and the bayonet fitted to the pipe.

    The bayonet must be looking down and not up or sideways. 

    The reason it needs to look down is when the hose is connected from the gas cooker, 

    it will give the hose a nice gentle bend, if sideways it could make the hose kink.

    Next the stability bracket or chain has to be fitted to the wall, 

    we tend to use the chain as it’s easy for the customer. 

    Should they wish to pull the gas cooker forward for cleaning, 

    all they need to do is disconnect the chain and the cooker can be moved.


    Once all the connections have been made it time to switch the gas supply back on.

    Once on, we purge any air in the pipe until the cooker lights, then we switch off.

    Then carry out another gas tightness test to make sure that the work we carried out is leak free.

    With gas hobs it’s basically the same, other than using a flexible hose pipe, 

    we use rigid pipe with a gas valve connected.

    It’s very important that you don’t try and connect your gas cookers or gas hobs yourself, 

    because should something go wrong you may find your home insurance is void. 

    Always use a gas safe registered engineer or company.
