My smoke alarm isn't working

It's important to test your smoke alarms periodically to make sure that they're working properly.

We've got a how-to video which explains the differences between mains and battery-operated smoke alarms and how to test them here.

It's a good idea to test your smoke alarms at least once per month.

If you've tested your smoke alarm and it's not working as it should, or it's damaged or missing, you should report a repair.
