10 Best Smoke Alarms UK 2024

£100 for a smoke alarm may seem like a big investment, but this alarm from Google lives up to its price tag. For one thing, it connects to your home's wifi, allowing you to control and monitor the alarm through the Google Nest app.

Plus, you can silence the alarm from your phone, and it will notify you if the alarm is activated when you're not home. There's also a light to guide your way at night, and it connects with all other devices in the Google Nest range. The sensors are truly top of the range, and will only need replacing every 10 years. 

In case of excessive smoke and unusually high room temperature this photoelectronic wireless smoke detector will activate and sound an alarm. The thing that sets it apart, however, is the option to connect up to multiple units of the same alarm using radio frequency.

Create a wireless network of 15 smoke detectors all within 35m of each other; as soon as one alarm activates they all go. Easy and quick to install with a magnetic fixing included, the alarm is neat and unobtrusive.

If you hate the thought of a clunky white plastic box ruining your carefully curated domestic aesthetic, then this colourful alternative might be just what you're after. The minimalist design comes in six colours, including a metallic chrome finish.

At almost £30 for a simple optical smoke alarm, you really are paying predominantly for the design. But if it's all your home requires, and it means you have a smoke alarm set up when you otherwise wouldn't, then it's worth every penny.

When detecting smoke in the air, this device not only sets off an alarm but also turns on a bright escape light, illuminating your route out of the building, making it ideal for hallways and landings.

The light also serves another useful function – it provides a visual notification that the alarm is going off. This could be useful for people who are hard of hearing or for environments where a normal alarm might not always be audible.

This smoke alarm from FireAngel uses a heat sensor to detect rapid changes in temperature. This sensitivity to heat, rather than smoke, means it won't be set off by cooking or vehicle fumes.

As such, it's ideal for use in a kitchen or garage, where burning toast or your car's exhaust set off other types of alarm. The company's patented Thermistek sensor responds up to twice as fast as other heat-sensitive alarms, giving you invaluable extra time to react.

This combination smoke and carbon monoxide alarm comes from Kidde, one of the leading names in fire safety products, so you can trust it will work well when it's important.

The unique selling point of this alarm is that upon detecting smoke or carbon monoxide, a voice alert rather than an alarm sound goes off. This voice alert tells you which of the two dangers has been detected, allowing you to act accordingly.

For people who are particularly concerned about levels of carbon monoxide in the home, the practical LCD display on this alarm will bring peace of mind. The display shows the concentration of the dangerous gas in real-time, so you'll know if something's amiss before it becomes too serious.

As well as the LCD display, there's also three coloured LEDs to give information on the safe functioning of the alarm, and a silence button to cancel false alarms.

The smallest smoke alarm on our list, this is a great pick if the size is an issue and you require something that takes up as little space as possible. This award-winning alarm has an advanced chipset that can detect dangerous smoke concentrations in seconds.

As well as it's neat proportions, another nice feature is the long-lasting battery. It's built into the alarm and can also be replaced, offering the best of both worlds in terms of a good battery life and not needing to buy new alarms. 

With a real 'love it or hate it', design, this one definitely won't be everyone's cup of tea! This is a smoke alarm for people who really want to make a statement with their home decor, or perhaps a bit of fun for a kids bedroom. 

As with the other Jalo alarm on our list, it's got a hefty price tag given how simple the technology is. But if you're after something interesting to put on your wall, do consider this, or the Jalo Kupu alarm below.

This twin pack of smoke alarms from Kidde enables you to provide a wide range of coverage throughout your home; place one downstairs and the other upstairs to ensure your family's safety.

One added feature that makes it stand out from other cheaper alarms is the hush button. This means that in the case of a false alarm (such as the standard burning toast), the alarm can be temporarily silenced at the touch of a button, avoiding the need for flapping around it with tea towels.
