Thinking about upgrading to a Nest Learning Thermostat or Hive Thermostat? It's easier than ever to bring modern comfort to your home or office.

Custom Settings: Control Your Heating & Hot Water Efficiently
- Smart radiator and heat pump configuration

Once your smart thermostat is up and running, it’s time to optimise the system. Create custom heating schedules from within the app to fit your daily routine (for example: lower the temperature after bedtime, or boost it as you return from work). Don’t forget to set up separate zones if your property uses smart radiator valves or multiple thermostats—you’ll stay cosy in every room and limit wasted energy.
Advanced users can link their thermostat with heat pumps (if supported), configure eco modes, or activate away settings to further trim bills. The learning thermostat function will get smarter as it tracks your preferences, often needing just a week or two to start making useful, energy-saving suggestions.
Advanced Smart Thermostat Features & Integrations
Linking Your Smart Thermostats With Smart Home Platforms
- Pairing with Amazon Alexa, Apple HomeKit, and Google Home

Modern smart thermostats are at their best when synced with your other smart home devices. Pair with Amazon Alexa, Apple HomeKit, or Google Home for total voice control (“Alexa, set the living room to 21°C!”). Use these platforms to set routines—for example, switch off your heating as you leave for work, or pre-heat your home on the way back from the office.
Integration with smart radiator and hot water controls means you can heat only the rooms you’re using, while also ensuring your hot water is always ready when needed. All these features streamline your daily schedule and keep your property efficient, comfortable, and ready for the future of energy management.
