The Complete Guide to Smart Heating in the UK
Smart heating is the highest-impact home automation upgrade you can make. The average UK household saves £150–£300 per year with a smart thermostat.
Types of smart heating
Smart Thermostat
Replaces your existing thermostat. Controls your boiler’s heating schedule remotely. Best for single-zone homes (one thermostat for the whole house).
Smart TRVs (Thermostatic Radiator Valves)
Replace your existing radiator valves. Each room gets individual temperature control. Add these to existing smart thermostat systems for multi-zone control.
Intelligent Heating Systems
Full systems that combine weather compensation, room-by-room control, and self-learning algorithms. Examples: Hive, Nest, tado°, Drayton Wiser.
UK-specific considerations
Boiler compatibility
Most smart thermostats work with combi, system, and heat-only boilers. Always check:
- Opentherm – some boilers support this protocol for modulating control
- 230V vs 24V – older systems may need professional installation
- Wireless or wired – wireless is easier but needs batteries
Hot water control
Important: Nest Learning Thermostat does NOT control hot water in the UK. Hive and tado° do. If you have a hot water tank, factor this in.
Smart meter integration
Some smart thermostats can integrate with your smart meter data for deeper energy insights.
