C02 Alarms

12 Sep 2022 | 4 comments

HI Guildy,

I have read conflicting information, we have a number of gas boilers in kitchens. Am I right in that we install a Co2 alarm in a kitchen (there is conflicting information that says not as the steam etc can effect the alarm)

We also have one property with the boiler in a cupboard in a bathroom – should we install an alarm there also?

    Yes, it would be needed in the kitchen. The only time it’s not required in the kitchen is if there’s only a gas cooker and no other fixed combustion appliance.

    A bathroom or lavatory is to be treated as a room used as living accommodation, so a CO alarm is needed if the boiler is in a bathroom or toilet.

    Thank you very much, just for confirmation gas cooker or gas hob is not required?

    Although not defined in the regulations, the guidance says:

    Gas cooker refers to any apparatus heated by gas and used for cooking food.

    This would therefore include both a cooker and hob in our view.
