Energy savings
Real-world studies (Nest, Tado) suggest 10–20% off heating bills — largely from geofencing (turning heating down when you leave) and learning your routine. Savings depend on how badly programmed the old thermostat was.
Nest Learning Thermostat
Learns your schedule after about a week, auto-adjusts flow temperature on newer OpenTherm-compatible boilers, integrates with Google Assistant. Slick design; typically £180–£220 supplied and fitted.
Hive
British Gas's option. Simple app, easy scheduling, geolocation, multi-zone if you fit extra receivers. Wide radiator TRV range. Typically £150–£200 fitted.
Tado
Best-in-class geofencing and per-room control via smart TRVs. Open Window Detection saves waste when a window's open. Requires subscription for some features. £150–£250 fitted.
Fitting
Most swaps take 1–2 hours by a Gas Safe engineer, including wiring the new receiver to the boiler and pairing the wireless thermostat. We install all three brands across Kingston, Twickenham and every KT/TW postcode.

Will a smart thermostat work with my boiler?
Nearly all modern boilers are compatible. Combi, system and older conventional boilers with a room thermostat can all use smart controls. We check compatibility during the quote.
Can I install one myself?
Some are marketed as DIY, but connecting to a boiler's live/switched-live circuit safely requires an electrician or Gas Safe engineer — cheaper long-term than mis-wiring.
