New Smoke & Carbon Monoxide Alarm Rules For Landlords

The UK Government has extended the rules for domestic smoke and carbon monoxide alarms within all rented accommodation in England.

Following parliamentary approval, it will soon be mandatory for landlords to repair or replace smoke and carbon monoxide alarms once they have been informed that they are faulty, although testing throughout the duration of a tenancy will remain the resident’s responsibility.

Landlords will also have to ensure a carbon monoxide alarm is installed in any room containing there is a ‘fixed combustion appliance’ (including a gas boiler). Where a new appliance is installed a carbon monoxide alarm will be required to be installed by law. Gas cookers appliances are excluded from the new rules.

The most significant changes are:

  • carbon monoxide alarms will be mandatory in rooms with a fixed combustion appliance, excluding gas cookers
  • carbon monoxide alarms will also be mandatory when a new heating appliance is installed, excluding gas cookers
  • landlords will have to repair or replace alarms when a tenant reports that they are faulty

“The revisions to the smoke and carbon monoxide detector regulations are both welcome and necessary to improve tenant safety.

“Private landlords have been required since 2015 to provide working smoke and carbon monoxide detectors where applicable in rented property, and the extension of the regulations to encompass gas boilers is a sensible amendment.”

No fixed timescale has yet been set, but the government has confirmed it will amend the Smoke and Carbon Monoxide Alarm (England) Regulations 2015 as soon as parliamentary time allows.
