Approved Document J has been amended – October 2022

Part of: Building control news and updates

Approved Document J has been amended to extend the provisions and update the guidance for carbon monoxide alarms in support of requirement J3 (Warning of release of carbon monoxide). This new edition sets out that a carbon monoxide alarm should be fitted upon the installation of fixed combustion appliances that burn solid fuels, gas fuels (excluding gas cookers) and oil fuels.

A carbon monoxide alarm (which complies with British Standard BS EN 50291) should be fitted when fixed combustion appliances are installed in new homes and in existing homes for new or replacement fixed combustion appliances.

The new arrangements came into force on 1 October 2022. Please see Approved Document J for guidance on the specification and placement of carbon monoxide alarms:
