Expert review

The Kidde 10Y29 smoke alarm is reasonably priced for a smoke detector with a lengthy 10-year battery. It works as a standalone alarm and can't be linked to other alarms in the home. This means that it won't be suitable for homes in Scotland when the alarm regulations change in 2022. But will this long-life optical smoke alarm give you the peace of mind you’re looking for by going off quickly enough if there’s a fire? Check out our full test results and star ratings to find out how it responded to four different types of fire.
