The cost of a smart thermostat can range from £120 to £220, depending on the make and model that you choose. On top of the unit cost, you also have to factor in the smart thermostat installation cost, which is usually around £30 to £80 (based on 1-2 hours of labour).

Factors affecting the cost of a smart thermostat

Installing a smart thermostat is fairly straightforward, so there aren’t a huge amount of factors to consider. The main ones that will affect how much you pay for your smart thermostat are:

  • Make and model of thermostat
  • Installation costs
  • Where you live (electrician hourly rates will vary across the country)

The average cost to supply and install a Hive smart thermostat is about £225. The main chunk of that cost is the thermostat unit itself, plus labour time to carry out the installation.

If you’re buying your first Hive unit, you’ll need to buy the Hive Hub, which is around £200. This lets you connect your Hive units to your smartphone. Any additional Hive thermostat units for your home will cost about £105.

Key features of Hive smart thermostats are multi-zone, hot water control, temperature notifications and holiday mode. To find out more, check out our Hive installation cost guide.

One of the key features of a Nest thermostat is that it learns your habits and so will bring an extra layer of smart to your home heating. It also has a handy green leaf symbol that appears when you’ve adjusted your thermostat to an energy-efficient temperature, to help you have a greener home.

A Tado unit offers many of the standard features of other smart thermostats, such as hot water control, frost protection, weather forecasts and holiday mode. It will also estimate your energy savings based on the number of hours you would be heating your home without it.

Benefits of a smart thermostat

If you’re still undecided as to whether a smart thermostat is right for you and your home, here are a few of the benefits to help you decide:

  • Complete control of your home heating. Smart thermostats combine the power and convenience of modern technology to help you manage your home heating. Use your smartphone or tablet to control temperature and hot water with a tap of your finger.
  • Save money on your energy bills. This is one of the biggest motivators for many homeowners, saving money. Smart thermostats give you greater control, which means you can be more precise with how and when you heat your home and water – and save up to 30% on your heating bills.
  • Use less energy. Another benefit of controlling your heating with a smart thermostat is that you use a lot less energy. You can have specific controls for times and days, including holiday mode when you’re out of town. No more wasting energy when you don’t need it!
  • High tech extras. Enjoy a heap of additional features, powered by the smart thermostat technology. From monitoring the weather to detecting the location of your phone to see when someone is home, many smart thermostats have features to help give you the best performance for your home heating – and it does all the heavy lifting for you.

Useful smart thermostat checklist

  • First, speak to your energy supplier to check that a smart thermostat will be compatible with your existing heating system.
  • Always research the options and features of each smart thermostat to decide which one is right for you and your home.
  • If in doubt, speak to your local smart thermostat specialists for their professional advice.
  • Shop around for fair and competitive smart thermostat prices.
  • When hiring a tradesperson, always choose someone with experience and relevant qualifications and accreditations, such as the Gas Safe Register, Competent Person Scheme, BESCA or Blue Flame Certification.
