Smart thermostats can help you to use energy efficiently and keep an eye on your heating costs and Nest is one of the most trusted names in the business. If you've been considering investing in a smart thermostat, Cyber Monday is a good time to go for it.

If you're in the US, Amazon has a deal on the Google Nest Thermostat. Buy it in the Sand or Snow colourway, and it's just $89.99, down from a launch price of $129. (The Charcoal and Fog models are $99.99.)

Granted, Amazon isn't alone in having this programmable Wi-Fi thermostat on sale today, but at $89.99, it has the best deal.

The Nest Thermostat is an affordable way to take charge of your heating. You can set a heating schedule, use location services so that it switches itself off when you leave the house and its Savings Finder will ensure you're not wasting money on heat.

If you're in the UK, the cheapest way to get Nest smart heating this sales weekend is to buy a Nest thermostat E.

Full disclosure: it's been discounted to this price before but that's unlikely to drop further in the near future.

You can find out more about what it's like to use in our review but in short, you can install it yourself (a big plus), schedule heating and set it to use location data on your phone so that it switches off automatically when you leave the house.
