Question to the Department for Levelling Up, Housing & Communities:

To ask Her Majesty's Government wat assessment they have made of the research conducted by Which? into the effectiveness of carbon monoxide alarms, published in June 2018.

In 2019, the Office for Product Safety and Standards examined a small sample of carbon monoxide and smoke alarms for compliance with safety requirements. It found that nine out of ten were compliant and the remaining carbon monoxide product was over-sensitive which did not give rise to safety concerns.

UK product safety legislation requires products, including carbon monoxide alarms, to be safe before they can be sold to consumers. Where the installation of carbon monoxide alarms is required by law or recommended, Government advice is that they should comply with British Standard BS EN 50291.
