Later this year, the importance of fitting CO alarms will increase further, affecting installers of heating oil boilers as well as Biomass and gas boilers.

From October 2015, it will be the law for Landlords to install working smoke and carbon monoxide alarms in their properties. This measure was announced at the beginning of March this year by the Housing Minister, Brandon Lewis.

Below, we have listed a few key facts to remember:

  • When a new or replacement fixed solid fuel appliance is installed in a dwelling, a CO alarm should be fitted in the same room where the appliance is located. This will soon expand to affect heating oil and gas appliance installations in privately rented properties
  • A CO alarm should comply with BS EN 50291:2001and be powered by an appropriate battery
  • Alarms should also have warning devices within them which will alert users when the alarm’s working life is nearly complete
  • A CO alarm should either be fitted onto the ceiling at least 300mm from any wall, or on a wall as high up as possible (above any doors and windows) but not within 150mm of the ceiling. Furthermore, the alarm should be between 1m-3m horizontally from the appliance.
