Smoke Alarm Regulations You Can’t Ignore

Landlords, Are You up to Code?
The latest legislation states that landlords must install smoke alarms in every rented property, with CO alarms required in every room containing fuel-burning appliances. Avoid the risk of fines, legal actions, or putting tenants in danger. Compliance isn’t optional.

Protect your property and ensure peace of mind for both you and your tenants. These regulations are in place to safeguard lives, prevent injuries, and protect property from damage. Failing to comply not only risks heavy fines but can also void your home or business insurance coverage.

FAQs

A Smoke & CO alarm is a dual safety device that detects both smoke from fires and carbon monoxide gas. It provides early warnings through alarms (and sometimes voice alerts), giving you vital time to react and keep your household safe.

Yes, carbon monoxide (CO) alarms expire. Most last between 5–10 years, as the internal sensor wears out over time. Always check the expiry date on the unit and follow the manufacturer’s guidelines for replacement.

A CO alarm beeps four times with a pause to warn of dangerous carbon monoxide. A single chirp every 30–60 seconds means a low battery or that the unit needs replacing. Newer models may also announce: “Warning: Carbon Monoxide.”

To test a carbon monoxide alarm, press and hold the test button until it beeps and flashes. If it doesn’t sound, replace the batteries, clean the unit, and try again. A chirping sound means low battery or end-of-life, so replace the alarm. Test monthly to ensure safety.

In the UK, it’s recommended to have at least one smoke alarm on every floor of your home, ideally positioned in a central hallway. Alarms should be mounted on the ceiling, at least 30cm away from light fittings.

If you only have a single alarm, ensure it’s placed where it can be heard clearly, even while you’re asleep.

Most detectors last 5 to 7 years, though newer models can last up to 10 years. Over time, the sensor loses sensitivity due to prolonged exposure, so it's important to replace it as recommended.
