Smart heating controls cost (UK 2026)
Controls stratum: smart thermostat, zoning, weather and load compensation. Installed cost ranges for 2026.
Controls are the fifth stratum but often the first that pays back at a system level: a heat-pump on weather compensation with the right curve delivers an additional 0.3 to 0.5 SCOP versus a unit on fixed flow.
Surveyed 1 October 2026. Ofgem cap for 1 October to 31 December 2026 applied (gas 7.97p, elec 26.32p, gas standing 29.68p, elec standing 54.83p). Next scheduled review 25 November 2026 (January cap announcement). [ref M5]
