The best smart thermostats make managing the heating in your home a doddle. They connect your central heating to your smartphone via the internet. So you can control the temperature in your home with a quick tap, wherever you are.

While most smart thermostats work the same, there’s a wide amount to choose from, and more coming online all the time. It’s a one-off investment that’ll stay with you for a while, so you want to get the right one.

Now obviously we’d always suggest you choose a Hive Thermostat! They’re the UK’s favourite after all… But that aside, here are some questions that it’s well worth considering to make sure you find the best thermostat for you – and that you know exactly what you’re paying for.

Does it come with professional installation?

First up, be sure to check if the thermostat you like comes with professional installation. And of course, if you know your way round a toolbox and fancy doing it yourself, make sure you’re not paying for an installation you don’t need.

Does the price include everything?

Lots of the comparison sites will look at the best smart thermostats in the UK based on price. However, you also need to think about whether you can install it yourself, as this will affect the initial price too, with professional installation usually costing extra.

It’s also worth checking what else you need to buy to get up and running. Most of the best wireless thermostats require some sort of hub to connect everything up to your WiFi. Without it you won’t be able to control your heating remotely.

Do you want to control your heating hands-free?

All smart thermostats let you control your heating remotely from your smartphone or tablet. However, if you’re still struggling to work out what is the best smart thermostat for you, it’s worth thinking about whether you’d like to be able to access it using other devices as well.

For example, many of the leading brands now work with Alexa and Google Assistant. Some are also compatible with Apple HomeKit. This means you can control the temperature in your home from your iPhone, iPad, Apple Watch or Mac.

So when you get caught in a downpour on your evening jog, you can ask Siri to boost your heating and hot water, ready for when you get home.

Is it compatible with other smart home devices?

For lots of people, a smart thermostat is a great way to dip their toe into the world of smart homes. But once you realise how convenient it is to be able to control your heating from anywhere you may be keen to come back for more. From smart lights to motion sensors, the possibilities are endless.

So when choosing the best WiFi thermostat for you it’s worth having a look at other products made by the same company, in case you decide to build on it over the years. Sticking with the same brand means you can get your products to work together and get your home operating seamlessly around you. For example, a motion sensor in the hall could trigger the lights to come on and heating to dial up a notch of two. It’s really useful stuff.

Those are the main questions to ask yourself before you get shopping. But it’s also worth having a think about whether some of these additional features would be helpful too.
