    Product Overview

    Enjoy complete peace of mind at home with the Nest Protect smart alarm. It’s a smoke and carbon monoxide detector in one, so you can rest assured that all fumes will be monitored. This alarm can detect varying levels of smoke, so when you’ve burnt the toast you’ll get a calm voice alert instead of the full siren.

It automatically tests its own batteries and sensors, and its 10 year lifespan means you’re protected for the long term. Plus, it has an integrated light with motion sensor, so it’ll gently illuminate your path at night when you need a glass of water.

    Features we love


    Through their line of smart products, Nest create a home that takes care of the people inside it. Their products are designed to talk not only to each other, but with other smart home products too, all coming together in the Nest app to give you a single point in which to manage everything. So by starting with a Nest, and adding more devices as you go, you can ensure your house tailors itself to you.

    Find your way in the dark

    It’s not just emergencies where this smart alarm is useful. There’s a built-in light that will activate if and when you walk underneath it. So if nature should happen to call during the night, the pathlight will softly illuminate your route to the bathroom.

    Works with Amazon Alexa

    This product is compatible with Amazon Alexa, providing you have an existing Alexa-enabled speaker. Just open the Alexa app on your smartphone or tablet and you’ll be able to connect this product. Then, you’ll be able to control it with just the power of your voice.

    Intelligently identifies the type of fire

    Get advanced warning of any emergencies thanks to the alarm’s ability to differentiate between different types of smoke. The Split-Spectrum sensor contained within the alarm analyses the particles in the air, and by doing so can detect both fast burning and smouldering fires faster than more traditional set-ups. As a result, you can rest assured that when called upon, the alarm will activate early ensuring you can get to safety.

    No more wailing

    Whilst most alarms will just sound a siren, this smart alarm talks to you. If you’ve got several alarms around the house, the friendly human voice will tell you which room the smoke is coming from. It will also let you know when its detected smoke coming from the kitchen before sounding the alarm, so you won’t need to start wafting the tea towel if you’ve just burnt your toast.

    Extra connectivity for extra safety

    This alarm is compatible with your Philips Hue products and Nest Thermostat for an even more intelligent home set-up. By synchronising these smart devices, they can provide added safety in an emergency. If the alarm goes off, your lights come on, illuminating your path, and your thermostat will turn off the heating to keep any danger from spreading.

    Works with smart speakers for voice control

    This product is compatible with selected smart speakers for even greater control. Once you’ve synchronised your device with your speaker, you’ll be able to turn it on and off or adjust the settings with a simple voice command. So you can get comfy, and let your virtual assistant do all the work.

    Excited over a smoke alarm!

    So easy to set up the Nest has a 10 year life span and AO delivered the most recent I have read that some companies have delivered those with a much older date, very happy with my purchase, expensive but saved on electrician expenses as this is battery operated, lovely nightlight which is also a bonus will be ordering another very soon

    Intuitive Alarm

    I’ve had these before and they’re really good. Plus I like the fact they light up at night (to help guide the little ones on their visit to the loo). I also like the fact the alarm speak as my batteries had failed on one of my other devices and the alarm sensed smoke and it was the voice activation telling me: there was smoke and that the alarm was going to sound, that woke me up which although was scary, made me realise how important having a voice activated alarm is.

    Nest Protect

    Love the Nest Protect. Makes you feel safer just having it there, plus the ‘night light’ is good
