It learns your habits, adjusts automatically, and helps you save money without sacrificing comfort. Whether you’re in a rented flat or a family home, these are the best smart thermostats available in the UK right now.

The Magic Step: Creating Easy Heating Routines

Once your thermostat is connected, you can automate your comfort. Try these simple Alexa routines:

“Good Morning” Routine: At 7 a.m., your thermostat warms the house to 20 °C while Alexa reads your weather forecast and plays your morning playlist.

“Away Mode” Routine: When you say “Alexa, I’m leaving,” your thermostat drops to eco temperature, saving energy until you return.

These small automations make your home feel smarter — and your bills lighter.
