Smoke Alarm Installation: common questions

What alarms does a rented home need?

In England, landlords must fit a smoke alarm on every storey used as living accommodation, and a carbon monoxide alarm in any room with a fixed combustion appliance, excluding gas cookers. Rules differ in Scotland and Wales, so check the latest guidance.

Where should a heat alarm go?

Heat alarms suit kitchens, where cooking fumes would set off a smoke alarm. Smoke alarms are best in hallways and on landings on each floor.

How long do alarms last?

Most smoke and heat alarms should be replaced about every 10 years. Check the date on the back of the unit, and test them monthly with the test button.
