Carbon Monoxide Awareness Week: What Landlords Need to Know to Keep Tenants Safe

Share  

Carbon Monoxide Awareness Week is now underway, making this the ideal moment for landlords to review the safety standards within their rental properties. Carbon monoxide (CO) is often referred to as the “silent killer” because it has no smell, taste or colour, yet exposure can be fatal. For landlords across Burnley, Pendle, Colne, Barrowford and the surrounding areas, ensuring that every home you let is adequately protected is not just best practice; it is a legal requirement.

Why landlords must take carbon monoxide seriously

Every year, preventable cases of CO poisoning occur due to faulty appliances, blocked flues, or malfunctioning alarms. Even well-maintained homes can be at risk if checks lapse or alarms are missing. With regulations tightening and tenant safety firmly under the spotlight, landlords have a responsibility to demonstrate that their properties meet the correct standards.

Your legal obligations

In England, landlords must:

  • Install carbon monoxide alarms in every room containing a fixed fuel-burning appliance (excluding gas cookers).

  • Test alarms on the first day of each new tenancy.

  • Ensure gas appliances are serviced annually by a Gas Safe registered engineer.

  • Provide tenants with a valid Gas Safety Certificate.

  • Keep clear maintenance and inspection records.

Non-compliance can lead to fines, enforcement action and increased risk to tenants.

Best practice for safe, compliant rental homes

To protect tenants and minimise risk, landlords should:

  • Test CO alarms regularly and replace any that are faulty or outdated.

  • Install alarms at head height, 1 to 3 metres from the relevant appliance.

  • Ensure boilers, fires, stoves and heaters are serviced annually.

  • Keep flues, chimneys and ventilation points clear.

  • Act promptly if tenants report symptoms, damp smells, scorch marks or appliance issues.

Consistent and documented checks are essential for demonstrating compliance and safeguarding your investment.
