Smart thermostat and heating controls across London

If your smart thermostat is not heating on schedule, the app keeps dropping out, or your Hive, Nest, or Tado never gave the promised savings, our Gas Safe engineers across London and the M25 wire it in properly, enable OpenTherm, and verify it works, typically within 30 to 60 minutes.

A smart thermostat is only as good as its installation. Most DIY installs leave OpenTherm modulation switched off (costing 5,10% efficiency), don't enable hot-water control properly on combi-DHW systems, and miss the proper geofencing setup that delivers the headline savings. The thermostat works, but it doesn't deliver the savings the manufacturer promised.

We install smart heating controls properly, wiring centre updated where required, OpenTherm enabled and verified with the boiler, hot-water schedule configured, weather compensation set up where supported, geofencing tied to all household phones, and a hand-over walk-through so you actually know how to use it. Average payback period properly installed: 18,30 months on heating bill savings.

Frequently Asked

Your questions answered

How much does a smart thermostat installation cost?
Smart-control installs are priced after a free on-site consultation and a written fixed-price quote, with no obligation. The thermostat hardware itself typically runs £150–250 for Hive/Nest/Tado and £200–500 for Honeywell evohome zone systems.
Will a smart thermostat actually save me money?
Yes, typically 10,18% on heating bills for an average London household, properly installed. Savings come from learning your patterns, geofencing (turning down when nobody's home), modulating boiler output via OpenTherm, and weather compensation. Payback period 18,30 months.
Which smart thermostat is best for my London home?
Honest opinion: Tado° if you're into geofencing precision and weather compensation; Hive for simplicity and the best UK system support; Nest for AI learning; Honeywell evohome if you want zone-by-zone control in a larger home (best ROI in 4+ bedroom houses).
Will a smart thermostat work with my boiler?
Almost certainly yes for any boiler made after 2005. Older non-condensing boilers may need a wiring centre upgrade. We check compatibility before quoting, no nasty surprises on the day.
Can you install a smart thermostat alongside underfloor heating?
Yes, Hive Multizone, Tado° and Honeywell evohome all support hybrid radiator + UFH installations. We design the configuration and install both ends.
