A Government Working party is considering extending the existing requirement to fit carbon monoxide alarms in rented properties. Currently, there is no requirement to fit a carbon monoxide (CO) alarm in a rented property unless it has a solid fuel appliance. This means that at the moment landlords with gas boilers do not have to fit a CO alarm in their property. Many landlords do, but it is not compulsory. The report is being backed by Alok Sharma MP, Minister of State for Housing and Planning. Under the new proposals landlords would have to fit a CO detector in all properties which contain any fuel burning appliance, including gas boilers.
