Thermostat Repair & Smart Upgrade

Your thermostat is the brain of your heating system — when it stops talking to the boiler, you're left with cold radiators, a permanently-on system, or wildly swinging room temperatures. We diagnose and fix every kind of thermostat and programmer fault, from a dead screen and missing batteries to wiring failures, stuck relays and pairing problems on wireless units. We also specialise in smart thermostat upgrades. Whether you want Google Nest, Hive, Tado, Honeywell evohome or Drayton Wiser, we'll spec the right kit for your boiler and pipework, fit it cleanly, replace the wiring centre if needed, pair it to your Wi-Fi and walk you through the app on your phone before we leave. Geofencing, schedules, hot-water timers and zone control — properly set up, not just bolted on. Most households save 10–25% on their heating bill in the first year after a smart upgrade — heating only the rooms you're actually using, only when you're actually home. We carry common thermostats and back-plates on the van so most jobs are completed in a single visit.
