Smart Thermostats

Using a smart thermostat will transform the way you heat your home. You’ll no longer need to be near your boiler to pre-programme your schedules. Instead, with smart heating controls you can use a simple mobile app to warm your house from anywhere. Heading home from work on a cold night? Use your phone to turn the heating on before you get back, to take the chill away. Maybe you’ve left the heating on by mistake? Switch it off with a simple swipe of your screen. A smart home thermostat will help you cut down on unnecessary spending when it comes to your energy bills, by making it easier than ever to switch off your heating when you don’t need it.

Nest Thermostats

Using a Nest smart thermostat from Google is a great way to cut down on energy waste. This smart room thermostat is clever enough to learn your schedule and automatically adjust heating or cooling when your house is occupied – or about to be occupied. Manual controls are also available if needed, all via the Nest app on your smartphone.

What is a smart thermostat?

A smart thermostat lets you control your heating from a phone or personal device. It connects via your Wi‑Fi allowing you to change the temperature in your home and schedule heating from anywhere.

How do smart thermostats save energy?

They only heat your home when needed. Features like schedules, geofencing (detecting when you’re out), and learning your routine can cut waste and lower bills.

Can I install a smart thermostat myself?

Some models are DIY‑friendly, especially wireless ones that replace a simple wall thermostat. Others need wiring into your boiler or heating controls and are best fitted by a professional. Check the thermostat’s information before attempting to install it.

Do smart thermostats work with all boilers?

Most work with combi, system, and heat‑only boilers. Always check compatibility, especially for older models or if you want advanced features like OpenTherm modulation.

What’s the difference between a smart thermostat and a smart TRV?

Smart thermostat: controls your whole heating system. 
Smart TRVs (thermostatic radiator valves): control heat for individual radiators, giving you zoned heating.

Do smart thermostats need Wi‑Fi?

Yes, for remote control and updates. If the internet goes down, most can still work like a standard thermostat using the manual controls.

How much can I save with a smart thermostat?

Savings can vary, but many households cut heating bills by 10–20% by using schedules, lowering the set temperature across the home, and cutting down on not heating empty rooms.
