10 Best Smart Smoke Detector 2025 in the UK

The Kidde 10SCO is a combination smoke and carbon monoxide alarm designed to save space by combining two detectors into one unit. It uses photoelectric detection technology, which is effective at sensing smoke from smoldering fires, helping increase safety in your home. The alarm features distinct voice warnings for smoke and CO, alongside a loud 85dB sound, making it clear what type of danger is present.

It’s powered by two AA alkaline batteries included in the package, but these need to be replaced roughly every 1 to 2 years, which means some ongoing maintenance rather than a true long-life battery. While the sensor itself lasts 10 years, matching the manufacturer’s warranty, this device does not have smart connectivity features like Wi-Fi or app control, so you won’t get remote alerts or integration with smart home systems.

Installation is straightforward, with screws and plugs supplied, and the unit is battery-powered, so no wiring is needed—perfect for easy setup anywhere in the home. The detector is lightweight and compact, with a clean white design that fits most interiors. Its major strengths are reliability, clear audio alerts, and a decade-long sensor life, but if you want smart home connectivity or longer battery life without replacements, this model might not meet those needs.

The FireAngel SCB10-R is a reliable combination smoke and carbon monoxide alarm designed to protect your home from two major hazards with one device. It uses advanced optical smoke detection to spot smouldering fires early and an electrochemical sensor for accurate carbon monoxide detection. This means it can alert you to invisible gas leaks as well as smoke, which is a strong advantage for comprehensive safety. The included battery is sealed and designed to last a full 10 years—the lifetime of the alarm—so you won’t need to worry about frequent replacements or battery changes. It also signals clearly when it’s time to replace the unit.

The alarm offers separate, distinct sounds and visual signals for smoke and CO, helping you quickly understand the type of danger. Installation is straightforward, suitable for wall or ceiling placement near bedrooms or living areas. However, it lacks smart features like Wi-Fi or app connectivity, which means you won’t be able to monitor it remotely or receive alerts on your phone. It also doesn’t support interlinking with other alarms for synchronized alerts across the house.

Certified with Kitemark and BSI standards, the alarm provides assurance of quality and safety and comes with a 3-year warranty. While it’s not a “smart” device by modern standards, it remains a practical, low-maintenance choice for those wanting dependable dual hazard protection with minimal upkeep.

The X-Sense Wi-Fi Combination Smoke and Carbon Monoxide Alarm (SC07-WX) is a reliable choice for those looking to enhance their home safety with modern technology. This device uses advanced photoelectric and electrochemical sensors, ensuring precise and quick detection of both smoke and carbon monoxide, which is vital for timely alerts and safety. A standout feature is its integration with the X-Sense Home Security app, which allows for remote monitoring and instant notifications for alarms, low battery, and faults, making it highly convenient for users who are frequently on the go or want to keep an eye on their home from anywhere.

Additionally, the device supports sharing with up to 12 other users, so multiple family members can stay informed about home safety. The product's direct 2.4 GHz Wi-Fi connectivity means it does not require a base station, simplifying the setup process. The included replaceable CR123A battery and the 10-year lifespan of the sensors contribute to its long-term reliability.

It's important to note that this model does not support an interconnect function or compatibility with the SBS50 base station, which could be a downside for users looking to integrate it with existing security systems. Installation is straightforward, with all the necessary components included in the package. The device has also received high customer ratings, indicating general user satisfaction. Despite some limitations regarding interconnectivity, the SC07-WX offers robust performance and smart features, making it a solid choice for a standalone smart smoke and carbon monoxide detector.
