Under the Regulations, all landlords are legally required to ensure a carbon monoxide alarm is fitted in any room that contains a fixed combustion appliance. This excludes gas cookers. Landlords are also legally required to ensure that smoke and carbon monoxide alarms are repaired or replaced once they are informed of a fault.
Landlords must also ensure that at least one smoke alarm is fitted on every storey where there is at least one room being used as living accommodation, as per the original Smoke and Carbon Monoxide Alarm (England) Regulations 2015.
Any landlord who is found to be in breach of these Regulations could be fined up to £5000.
Tenants who find their alarms are not working should first try to replace the batteries. If the alarm still does not work after the batteries have been replaced, or if the tenant is unable to replace the batteries themselves, they should inform their landlord as soon as possible.
The Department for Levelling Up, Housing & Communities has published guidance and frequently asked questions on the new Regulations for both landlords and tenants. These can be found on the gov.uk website.
