01
Room fit
Match the room
Hallways, landings and bedrooms usually call for smoke alarms; kitchens and garages may suit heat alarms instead.
Read the guide →02
Battery choice
Pick the power source
Replaceable batteries suit simple replacements, while sealed 10-year batteries reduce routine maintenance.
Read the guide →03
Whole-home set-up
Decide on interlinking
Linked alarms are useful where you want one alarm to trigger the rest of the home system.
Read the guide →Questions shoppers ask
Which smoke alarm is best for a hallway?+
A standard optical smoke alarm is a common choice for hallways and landing areas in UK homes.
Should I choose a 10-year battery model?+
If you want less battery maintenance, a sealed 10-year battery alarm is often the easiest option.
What is the benefit of an interlinked alarm?+
Interlinked alarms let the whole system sound together, which can help in larger or multi-storey homes.
Are smart smoke alarms worth considering?+
They can be useful if you want app alerts or connected features, especially in busier households.
How often should I test a smoke alarm?+
Use the test button regularly, following the manufacturer’s guidance for your exact model.
When should I replace a smoke alarm?+
Replace the unit at the end of its stated life, or sooner if the manufacturer advises it.
