What did the consultation propose?

The proposed amendments seek to ensure that new build and materially altered properties in England have a Carbon Monoxide (CO) alarm installed wherever a fuel burning appliance is present (excluding cookers), as per the Building Regulations, Approved Document J.

In addition, it also looked to remove the word ‘solid’ from the requirements for CO alarm installation.


As of 1st October 2022, in England, Carbon Monoxide alarms are required for:

  1. Solid fuel (Including solid biofuel) appliances up to 50kW
  2. Gas appliances up to 70kW
  3. Oil burning appliances up to 45kW
