What we fit

Smart thermostats and Heatmiser controls we install

Hive, Nest and tado° suit most homes with radiators. Heatmiser comes into its own with underfloor heating or several zones to run. We’ll tell you honestly which fits — see our guide to smart heating controls to compare them.

Hive

A Hive thermostat and receiver wired to your boiler, with hot water control on homes with a tank (the Heating and Hot Water version), and Hive radiator valves if you want room-by-room control.

Google Nest

The Nest Learning Thermostat picks up your routine and builds its own schedule. A Heat Link is fitted at your boiler, and we set it all up with you.

tado°

A smart thermostat plus tado° smart radiator valves for room-by-room control. It works with Apple Home, Google Home and Alexa, and has an away mode that turns the heating down when everyone’s out (automatic with tado°’s Auto-Assist subscription).

How it works

Three steps to a smarter, cosier home

  1. Free survey

    We check your boiler, wiring and Wi-Fi, ask how you live, and recommend the system that suits your home, and exactly which kit to buy.

  2. Fit & set up

    Neat, tidy installation, usually in a single visit. We connect everything to the app and set your schedules with you.

  3. We show you how

    A proper walkthrough on your own phone before we leave, and we’re a call away if anything needs tweaking later.

Why go smart

Warm when you want it. Off when you don’t.

Smart controls stop you paying to heat an empty house — without ever coming home to a cold one.

Control from anywhere

Turn the heating up on the way home, or off when plans change.

Heat only the rooms you use

Smart radiator valves give each room its own schedule.

Eco & away modes

Geofencing knows when the last person leaves and turns things down.

Works with your voice assistant

Alexa, Google Assistant or Apple Home, depending on the system.

FAQs

Good questions

How much does it cost to fit a smart thermostat?

Fitting starts from £75, plus the cost of the thermostat itself. We don’t sell the equipment; we tell you exactly what to buy. The total depends on the brand, whether you add smart radiator valves, and how your boiler and wiring are set up. You’ll get a clear quote before any work starts.

Can I install a smart thermostat myself?

Some people do. It usually means working with mains-voltage wiring at your boiler, and a mistake can leave you without heating or hot water. Hive, for example, says you need to be competent with electrical wiring and recommends an experienced tradesperson.

Will a smart thermostat work with my boiler?

Most combi, system and oil boilers can take smart controls, but not every model or setup suits every brand. We check your boiler, wiring and Wi-Fi on the survey before you spend anything.

Are there any downsides to smart thermostats?

A few. You need Wi-Fi for app control (your heating still runs on its schedule if the internet drops), some extra features such as tado°’s automatic away mode are paid subscriptions, and how much you save depends on how you use it. We’ll be straight with you about all of that before you buy.

Do smart thermostats really save money?

They can, mainly by not heating the house when nobody’s in and by heating only the rooms you use. The saving depends on your home and your habits, so we won’t promise a figure — we’ll set your schedules up so the controls actually get used.

Which is best: Hive, Nest or tado°?

It depends on your home and how you live. Room-by-room control, hot water, voice assistants and budget all play a part — we’ll talk you through it honestly and recommend the one that fits.

Can I control underfloor heating from my phone?

Yes. Heatmiser’s smart thermostats connect to an app so you can set each zone’s schedule and temperature from anywhere. We fit and set up the controls — not the underfloor heating pipes or mats themselves.
