Smart thermostats can switch your heating on or off remotely via the internet. So if your plans or the weather change, you can adapt your heating to match. Prices range from around £100 to £250, although some energy suppliers offer them as part of fixed-term gas and electricity deals.
Many smart thermostats show you how much heating you're using. Some can also monitor your usage, learn your routine, or turn on when you're near home (using GPS data). As with a traditional thermostat, you can program the times when you want the heating to turn on and off - but you do this via your phone or computer, rather than the thermostat itself.
Whether or not a smart thermostat could save you money will depend on factors including the price you pay for the system, how effectively you use your existing heating controls, how comfortable you are using apps, and if you intend to stay in your current property for several years to recoup the cost of installation through your reduced bills.
See our comprehensive guide to smart thermostats to decide whether they're the best choice for you.
