Carbon Monoxide Alarm Requirements for Landlords in England

This guide applies to landlords renting out homes in England. It explains the practical carbon monoxide alarm requirements for rental properties, alongside the smoke alarm checks that usually sit in the same move-in and inspection process.

It is practical compliance guidance, not legal advice. Use it to organise alarm locations, tenancy start checks, tenant fault reports, and evidence records alongside your wider landlord compliance checklist.

For landlords in England, carbon monoxide and smoke alarm rules are legal requirements. If required alarms are missing, not working at the start of a tenancy, or not repaired or replaced after a fault is reported, the local council can take enforcement action and may issue a financial penalty.

Carbon Monoxide Detector Requirements For Rental Properties

The carbon monoxide detector requirement is room-based. Walk the property and identify each room used wholly or partly as living accommodation that contains a fixed combustion appliance.

Common examples include:

• A room with a gas or oil boiler.
• A living room with a log burner, coal fire, or gas fire.
• A utility room, hallway, bathroom, or other living accommodation space containing a relevant fixed combustion appliance.

The gas cooker exception matters. A room does not need a carbon monoxide alarm solely because it contains a gas cooker, but you should still check whether the same room contains another fixed combustion appliance.

Simple Compliance Checklist

• List every storey used as living accommodation and confirm at least one smoke alarm is present.
• List every room with a fixed combustion appliance, excluding gas cookers, and confirm a carbon monoxide alarm is present.
• Install alarms according to the manufacturer's instructions and keep the instructions or product details where practical.
• Test each required alarm on the day a new tenancy begins.
• Record the test date, alarm locations, and who completed the check.
• Repair or replace a reported faulty alarm as soon as reasonably practicable.
• Add alarm checks to your property inspection routine and maintenance records.

Deadlines To Track

• Check required alarms on the day each new tenancy begins.
• Replace or repair a required alarm as soon as reasonably practicable after a tenant reports a fault.
• Review alarm placement before marketing, renewal, major repairs, boiler replacement, stove installation, or property layout changes.

Evidence To Keep

• A dated move-in alarm test record.
• Notes showing smoke alarm locations by storey.
• Notes showing carbon monoxide alarm locations by room and appliance.
• Tenant reports of alarm faults and follow-up action taken.
• Receipts, invoices, or photos for replacement alarms where relevant.
• Property inspection notes confirming alarms are present and working.

Where RentPilot Fits

Use RentPilot maintenance tracking to record alarm tests, tenant fault reports, replacement dates, contractor notes, and inspection follow-up. That keeps carbon monoxide detector evidence with the property record instead of scattered across email, photos, and spreadsheets.
