Smoke Alarms

Smoke alarms are a vital part of home safety and one of the simplest, most effective ways to protect your family. Whether it’s in the hallway, on the landing, or in your bedrooms and lounges, having a working smoke detector nearby could be the difference between escape and tragedy.

In fact, just one working smoke alarm in your home can increase your chances of surviving a fire by up to 90%. That’s a small investment for such a life-saving advantage. Our range of smoke alarms is carefully selected to suit every room and every need, so you can shop with confidence and create a safer home today.
