Smart Thermostat Installation
We fit smart, Wi-Fi-enabled thermostats so you can control your heating from your phone, on a schedule that suits your home. Done properly, with your wiring checked and your system left working exactly as it should.
What's included with your installation
Every smart thermostat job covers the same careful groundwork, whatever brand you've chosen.
Wiring & Compatibility Check
We check your existing wiring, including whether you have a C-wire, before any work starts so there are no surprises.
Removal & Mounting
Your old thermostat is safely removed and the new one mounted level and wired in correctly.
Wi-Fi & App Setup
We connect the thermostat to your Wi-Fi and get the app paired so you're ready to control it straight away.
Schedule & Settings Support
We help set up an initial heating schedule and talk you through the basics before we leave.
Swapping your old thermostat for one you can control from anywhere
A smart thermostat replaces your existing wall control with a Wi-Fi-enabled version, letting you turn the heating up, down, or off from an app, wherever you happen to be. It's a small job with a noticeable everyday benefit, and it's one we're regularly asked to do alongside boiler servicing, heating repairs, or as part of a wider central heating upgrade.
We start by turning off power to the system and carefully checking and photographing your existing wiring before anything is disconnected. Some homes have a C-wire already in place for continuous power; others don't, in which case we'll fit an adapter or find another suitable solution so the new thermostat runs reliably. Once the new baseplate is mounted and wired in, we restore power, connect it to your Wi-Fi, and walk you through the app so you're using it with confidence before we leave.
A smart thermostat is only as good as the wiring and setup behind it, that's the bit worth getting right.
The main thing customers want to know is whether their system will actually work with a smart thermostat, and whether it'll be a big disruptive job. In most cases it's straightforward and quick once we've confirmed compatibility, though homes with unusual or older wiring can take a bit longer to get right.
More information
We fit smart thermostats for homeowners across Brighton, Hove, Woodingdean, Worthing, Lewes, Shoreham-by-Sea, Haywards Heath, Seaford and Burgess Hill, often as a quick add-on when we're already on site for a boiler service, heating check, or bathroom installation. As a Gas Safe registered and accredited Vaillant installer, we're used to working on the heating systems behind the thermostat, not just the thermostat itself.
If you're not sure whether your current wiring will support a smart thermostat, or which brand suits your system, get in touch and we'll talk it through before booking anything in.

“New Boiler. Ryan, Jake and the RK Team were brilliant. Fitted a new boiler and removed the old tanks. They were polite, tidy and we are really happy with the new boiler and Hive thermostat. Highly recommend using RK for and plumbing/boiler needs”
Jamie Bevan
“Ryan and his team were lovely! Did a really lovely job making my once spaghetti-junction-resembling pipes lovely and straight and simple! They also fitted a new boiler and radiators and got me all set up for a Hive - I feel like a proper grown up (I'm 47 😂). They went above and beyond and were a pleasure to have around. Will definitely use them again.”
