Test your smoke alarm and any carbon monoxide detector monthly by pressing the button. If the alarm doesn’t sound, replace the battery – or contact us immediately if you have a mains-powered smoke alarm fitted, so we can arrange to fix it. This is the most important check you can do to protect yourself from fire or carbon monoxide poisoning.
Replace the batteries each year or when the alarm sounds to show the batteries are running low.
Consider fitting extra battery-powered alarms in the centre of the ceiling – away from any lights.
