How often should I test my smoke detector?

Left double quote

Ideally every week.

Answered by Sarah, Electrical Safety Expert

Smoke alarms are essential in keeping you safe by alerting you in the event of a fire. There should be a minimum of one smoke alarm per floor with a heat detector in the kitchen. You should fit enough alarms to cover all areas where a fire could start. Make sure they are tested regularly - ideally every week.

Also check your smoke alarm's expiry date: Smoke alarms have a lifespan, usually around 10 years. Even if it sounds fine during tests, it might not be reliable in an actual fire.
