Smart Thermostats & Heating Controls — UK-Wide, Qualified & Priced Up Front
Smart thermostats & heating controls — handled UK-wide by qualified, insured local engineers, with the price agreed before work starts and honest advice on what your system actually needs.
What good controls actually do
Heating controls are the cheapest efficiency upgrade a wet heating system can get, because they attack the biggest waste: heating the home when nobody needs it, and overshooting the temperature when they do. The modern minimum is a programmable room thermostat plus thermostatic radiator valves; the worthwhile maximum for most homes adds a smart thermostat with scheduling from your phone, presence detection or geofencing, and — the sleeper feature — load or weather compensation, which lets a compatible boiler modulate down and run in its efficient condensing range far more of the time.
The savings claims around smart controls range from honest to heroic. The honest version: a household that currently runs heating on a manual timer and adjusts little will save meaningfully; a household already managing schedules carefully saves less from the scheduling and more from compensation features, which are about how the boiler runs rather than when. Compatibility matters — the compensation standards (OpenTherm and manufacturers' own protocols) only work on boilers that speak them, which is exactly what we check before recommending anything.
Installation and honest product advice
Fitting is straightforward for a competent engineer: the receiver wires at the boiler, the thermostat sits where it can sense the home honestly (not above a radiator, not in a hallway draught), TRVs go on radiators that lack them, and the schedule gets set up with you rather than left at factory defaults. Most installs are done within a couple of hours, and the walkthrough at the end — how to set schedules, how holiday mode works, what the app actually controls — is where the savings get locked in or lost.
On products: the mainstream smart thermostats are all competent, and the right choice hinges on your boiler's compatibility, whether you want per-room control via smart TRVs, and how much app sophistication you'll genuinely use. We'll happily fit a unit you've already bought, or supply one matched to your boiler — with the reasoning stated, because controls recommendations driven by installer margin rather than compatibility are one of this trade's quieter bad habits.

Frequently asked questions
Will a smart thermostat cut my bills?
If you currently heat on a fixed timer with little adjustment, yes — meaningfully. If you already manage schedules tightly, the gains come mostly from compensation features that let the boiler modulate, which need a compatible boiler. We'll tell you which case you're in before you spend.
What is OpenTherm and do I need it?
A protocol letting the thermostat continuously modulate a compatible boiler rather than switching it on and off — smoother running, more time condensing, better efficiency. If your boiler supports it, choosing a compatible thermostat is worth doing; if not, a well-set standard smart stat still serves.
Can you fit a thermostat I've already bought?
Yes — supply-and-fit or fit-only both priced fairly. The engineer checks compatibility with your boiler first; if the unit you've bought won't deliver its headline features on your system, you'll be told before it goes on the wall.
Do smart TRVs make sense?
For larger homes or ones with rooms used very differently, per-room scheduling genuinely helps. For small, open homes they're mostly a gadget. They're the classic 'depends on your house' product, and the honest answer follows a two-minute conversation about how you live.
