The Nest Protect passed our sealed incense test with flying colours: the smoke alarm went off first, followed by the CO alarm five minutes later; according to the app, the CO level was 414ppm and increasing. We can’t think of a better CO currently alarm on the market, particularly as it also detects smoke. The Nest Protect is very easy to set up: simply remove the battery tab, launch the app, log in to your Wi-Fi, give it a name (kitchen, lounge and so on) and mount it in a suitably elevated place on a wall. The second impression, on opening the box (and without even seeing the detector), was that this was going to be a quality product.

If a fire breaks out while you’re asleep, the smoke it emits will set off the alarm, hopefully giving you time to get out before being asphyxiated by the fire’s deadly concoction of chemical gases. I’m a huge advocate for carbon monoxide detectors in homes, and for me, they have the same importance as a smoke detector. Unfortunately, this importance isn’t shared across the broader demograph of the United Kingdom, with Policy Connect estimating that only 46% of homes in the UK have a CO detector installed.Most manufacturers suggest locating your alarm next to or near a gas appliance, and it’s worth having one in the same room as any fire or wood-burning stove. It should be around 1.5m from the ground and at least 30cm away from any ceiling, and most can be mounted on a worktop, shelf or table – or simply mounted on the wall.

Carbon monoxide sensors have a finite lifespan of between five and seven years, although a few manufacturers now claim that their sensors will last a full ten years. Generally speaking, it’s worth playing it safe and replacing your alarm a year or two before its life is supposed to run out. Tests in the US have shown that alarms over eight years old can fail to detect CO at levels of above 400ppm.
