10 Best Room Thermometers UK 2023

While you can still buy traditional glass designs, the most accurate way to measure the temperature of your room, baby's nursery, greenhouse or even your wine cellar is with a digital wall thermometer. Many also double up as hydrometers, which measure humidity, as well as syncing with your phone or device and your smart home setup too. 


However, some people may find all of these new functions confusing. To help you sift through the specs and find the perfect room thermometer for your home, we've compiled a feature-led buying guide. Then, check out our top 10 recommendations available to order online from Amazon, Boots and Argos.

How to Choose a Room Thermometer in the UK

Key Points to Consider
  1. Choose an Indoor, Outdoor or Baby Room Thermometer, Depending on Its Purpose
  2. Check the Thermometer’s Refresh Rate and Range for an Accurate Temperature Reading
  3. Pick a Model With a Good Hygrometer if You’re Conscious of Humidity Levels
  4. Consider a Thermometer That Comes With an App to Set Up a Smart Home

Decide Between an Indoor, Indoor/Outdoor and Baby Room Thermometer Based on Your Intended Purpose

Decide Between an Indoor, Indoor/Outdoor and Baby Room Thermometer Based on Your Intended Purpose

There are three main types of room thermometer and each serves a different purpose, so it's likely that one will be more suitable for your needs. The simplest indoor devices look a bit like a thermostat and can be mounted or placed anywhere in your home. Look for products with additional sensors if you want to record temperatures in more than one room. 


Another option is an indoor/outdoor thermometer, which will always come with a sensor that is able, and safe, to be placed externally. As well as displaying both the inside and outside temperature, more advanced models will give you a weather forecast and data on air pressure too. 


While you can use any of the above gadgets to monitor the temperature in your child's room while they are sleeping, baby-specific designs may be more suited to the task. Many double up as night lights or bath toys, which are things you'll probably be buying anyway if you have little ones! The latter of these can also measure your baby's bathwater, to ensure a comfortable splashing session.

For the Best Accuracy, Check That the Reading Will Be Correct to at Least ±1°C and Will Refresh Within 10 Seconds

For the Best Accuracy, Check That the Reading Will Be Correct to at Least ±1°C and Will Refresh Within 10 Seconds

First things first, you want your thermometer to be accurate — so look for those promising that the reading will be correct to at least ±1°C and will have a quick refresh time (the best on the market recalibrate every two seconds). You'll also want to check whether its range meets your requirements, although most should do so at between -50 and 70°C! 


If you're not a Celsius user, check whether the thermometer supports Fahrenheit, and consider whether you'd find a minimum and maximum temperature display useful. Thermometers with this feature will automatically save previous readings, allowing you to keep an eye on changes in the room's climate. 


Finally, it's worth examining the size of both the unit and the display. Some will have smaller screens that you may not be able to see from a distance, whereas others will prioritise certain readings in larger digits. A backlight is also handy to have, in case you're placing the gadget somewhere dark or want to be able to take readings at night.

If You're Conscious of Humidity Levels, Pick a Design With a Good Hygrometer That Offers a Range Between 10% and 99% RH

If You're Conscious of Humidity Levels, Pick a Design With a Good Hygrometer That Offers a Range Between 10% and 99% RH

Depending on where you live and whether you or someone in your household suffers from allergies, asthma or skin issues, you might want to keep an eye on the humidity in your home. This feature will also be of interest if you want to monitor moisture levels in a greenhouse or to keep an exotic pet comfortable. 


A good hygrometer will offer a range between 10% and 99% RH (relative humidity), with some helpfully displaying whether the current reading is considered good, bad or satisfactory. The recommended level is 40 to 50% and, ideally, your chosen thermometer should offer accuracy of at least ±5% RH.

If You're Setting up a Smart Home, Consider Thermometers That Come With App Connectivity to Keep Everything Automated

If You're Setting up a Smart Home, Consider Thermometers That Come With App Connectivity to Keep Everything Automated

Want the convenience of being able to monitor temperatures and receive alerts from a space further away in the home like a cellar, attic or greenhouse? Consider thermometers that come with app connectivity. These are also great for those who want to check levels without disturbing a sleeping baby!


You have two options here: a regular LCD display unit that comes with an app or a sensor with no display whose readings you will only be able to see from its app. For either, you might want to check the range if you plan on placing the thermometer somewhere further away like a greenhouse. 


Smarter still, it's also possible to link some gadgets with your home automation system so you can control temperatures from afar. If you'd like to connect to more than one thermometer in a number of rooms, check how many units the app can sync with. You might also want to note whether the data it records can be stored on a cloud for even more convenience.

A Smart Temperature and Weather Station With Style

The first thing you'll notice about this station is its attractive design — it would look great on a bedside table or living room dresser. Plus, with all the data it displays, that's exactly where it would be most useful! By synchronising with Google Weather, you'll see temperature, humidity, UV index, wind speed and the weather forecast. 


There are also three weatherproof remote sensors included, allowing you to keep track of other rooms or spaces up to 60 m away. Best of all, the brilliant app not only alerts you of changes but it also records humidity history and other data via easy-to-read graphs. If it's features you want, this amazing thermometer ticks all of the boxes!

Monitor Your Greenhouse or Wine Cellar From Afar

This option is ideal for anyone looking to monitor different areas of their home, such as a greenhouse, pet area or wine cellar — or just another room if you have a big house! By connecting to the associated app via Bluetooth, you'll get real-time readings from 60 metres away. 


These readings are updated every two seconds and can keep track of essential information including humidity levels and minimum/maximum temperature. The app will also alert you if levels become too high or low. As for the unit itself, its large LCD screen clearly displays all of the above, alongside a comfort indicator.

Includes Three Sensors With Their Own Screens

The Kalawen room thermometer has many excellent features, with the main one being the amount of detailed information it provides. As well as indoor and outdoor temperatures, there's data on humidity, barometric pressure and weather — plus it even has a nifty alarm! All of this is shown on a bright, full-colour LED display.


Included are three remote sensors which show the readings on separate small screens, meaning you don't have to waste your time running back and forth if you require humidity data for your child's bedroom. Helpfully, the device also runs on either an AC mains adapter or AA batteries.

The Best Baby Room Thermometer on the Market

Health professionals advise that a baby's room should maintain a temperature within 16-20°C, which can become a bit of an obsession for new parents. In addition to being small, subtle and stylish, the Groegg2 makes the whole process a total breeze by displaying the temperature in large, clear digits. 


Additionally, this thermometer-come-nightlight actually changes colour to indicate whether the temperature is suitable — red or orange when it's too hot or warm, blue when it's a little cold and yellow when it meets the recommended guideline temperature. A very highly rated product that you'll get loads of use from!

Feature-Free Sensors Keep It Simple

Unlike most of the designs on our list, this set is completely feature-free with no display unit. Instead, you'll view detailed data straight from the Govee app, which is perfect if you don't want to ruin the aesthetics of your home or if you'd simply prefer to access information with the touch of a button at all times.

We also like that this product can link up via either WiFi or Bluetooth, and that it can be added as a widget to your phone's home screen. The sensors require batteries, so you'll need to be prepared to replace these fairly regularly (around three or four times a year), but at least you won't have to remember to charge them!

A Smart System That's Compatible With Alexa

Are you in the process of making your home fully automated? This is one of the only room thermometers that's compatible with Alexa, Google Assistant and other smart systems. Plus, with the included SwitchBot App, you can set a "Scene" to modify the temperature or humidity in your home. 


Even if you're only interested in the app and thermometer, the other smart features are very appealing too. Not only can the app store unlimited data, but the accuracy, range and other specifications are top-notch. Just bear in mind that you'll need to purchase an additional SwitchBot Hub Mini for the integration, although they're not pricey.

An Affordable Way to Display the Essentials

If you're not interested in any bells and whistles but you would like to monitor the temperature in various rooms around your house, pick this affordable three-pack by ThermoPro. The sleek, compact units can be wall-mounted, stood or even stuck on the fridge and use fuss-free, long-lasting AAA batteries. 


While there's no backlight and only temperature, humidity and comfort levels are recorded, keeping things minimal means that the display is easy to read at a glance. There is also no mention of the specific accuracy, but the manufacturer does promise that an advanced high-precision sensor is used.

A Wealth of Info for up to Three Rooms

Looking more like a mini-tablet than a wall thermometer, this indoor/outdoor unit displays a wealth of information on its backlit touchscreen. You'll be able to view the temperature and humidity from wherever you've placed the three sensors, all of which are IPX4 water-resistant


It offers a good range of -40°C to 70°C and 20% to 95% for humidity, as well as the ability to see trends of your chosen locations in case you need to adjust the temperature in those places. With all of this detailed data available though, it would be handy if this product came with an app.

All the Data You Need in a Neat Package

This little gadget may be palm-sized, but it still packs in a lot of data on its screen. Ideal for pretty much anywhere, from nurseries to attics full of precious items, it can easily be moved around and mounted in three different ways. We particularly like the comfort meter gauge, which is simpler to interpret than other options on our list. 


The downsides are that this thermometer's range doesn't go below 0℃ and its refreshing time for accuracy is 15 seconds, which is a bit slow. The fact that you won't be able to see all of those readings without getting up close might not be convenient for some people either.

Monitor Your Baby's Room and Bath Temperature

This simple stand-up thermometer will help you keep an eye on the temperature in your baby's nursery as well as when it's time to bathe them. There is no accuracy range but after a quick tap, the unit will calibrate and display the current temperature in seconds.


In terms of hygrometer functionality, the LED warning light will flash red if bathwater is above 39°C, and therefore too hot for your little one. It can also display in Centigrade or Fahrenhei, depending on your preference. While this is a very basic thermometer, it's nonetheless a valuable one for parents of young children.
