Best Smart Thermostats for Heat Pumps UK (2026 Guide)

Best Overall

1. tado° Smart Thermostat X (2nd gen)

Best for: homeowners wanting a modern, expandable smart-heating system with explicit support for compatible boilers, heat pumps and water-based underfloor heating.

The second-generation tado° Smart Thermostat X improves the physical thermostat while retaining the wider tado° X ecosystem. The wired thermostat is slimmer at 17.8mm, uses a rechargeable USB-C battery and includes a redesigned LED matrix display, light ring and physical controls. More importantly for this comparison, tado° states that the wired model supports compatible boilers, heat pumps and water-based underfloor heating using Relay or OpenTherm.

Why we recommend it: tado° currently offers one of the strongest combinations of mainstream usability, heating-system compatibility, smart-home connectivity and room-by-room expansion. It is easier to recommend to the average homeowner than some of the more specialist zoning systems below.

Best for Advanced Zoning

2. Honeywell Home evohome

Best for: larger properties, complex radiator layouts, mixed radiator and underfloor-heating systems, and homeowners who want deeper room-by-room heat-pump control.

evohome is closer to a complete smart heating-control system than a simple wall thermostat. It can manage up to 12 heating or cooling zones and includes installer settings intended for heat-pump operation.

Why we recommend it: evohome is one of the strongest choices if you are designing room-by-room control as part of the heat-pump installation rather than simply replacing one central wall thermostat.

Best for you if: you have a larger home, several heating zones or a mix of radiators and wet underfloor heating.

Best Value Multi-Room System

3. Drayton Wiser

Best for: homeowners who want effective smart zoning and radiator control without moving into one of the more expensive ecosystems.

Wiser is particularly attractive as an expandable system. Wiser Smart Radiator Thermostats allow individual rooms to have different target temperatures, while the wider system can also support room thermostats and wet underfloor-heating control.

Why we recommend it: Wiser offers much of the practical zoning functionality most homeowners actually need without requiring the more involved setup of evohome.

Best for you if: you have radiators in several rooms and want a sensible, expandable smart-heating system at a more accessible cost than some premium alternatives.

Best for Underfloor Heating

4. Heatmiser neoStat V3

Best for: multi-zone properties, wet underfloor heating and homes where individual wired room thermostats form part of the heating design.

Heatmiser is different from tado°, Nest or Hive. It makes most sense when the thermostat forms part of a properly designed zone-control system rather than simply replacing one central wall controller. The neoStat V3 supports programmable heating control, remote sensing, floor-temperature limiting and mesh networking when used within the wider neo ecosystem.

Why we recommend it: a heat-pump home with several wet underfloor-heating zones has very different control requirements from a conventional single-zone radiator home. Heatmiser is particularly strong in that environment.

Best for you if: your installer is building a multi-zone or underfloor-heating control strategy rather than relying on one central thermostat.

Best Smart-Home Experience

5. Google Nest Learning Thermostat

Best for: simpler heat-pump installations where design, automation and day-to-day usability matter more than advanced zoning.

The UK Nest Learning Thermostat remains one of the most polished thermostats to use. The display, app and automatic scheduling are easy to understand, and suitable heat-pump installations can be controlled through the Nest Heat Link.

Why we recommend it: Nest remains a good option if you want a simple, polished control experience and the heat pump installer confirms that the Heat Link arrangement is appropriate.

Why it ranks below tado°, evohome and Wiser: those systems offer a clearer path to detailed room-by-room control.

Best if You Already Use Hive

6. Hive Thermostat

Best for: homeowners already invested in Hive who want familiar app-based space-heating control and whose heat pump supports third-party thermostat input.

Hive can control space heating on compatible heat pumps that accept third-party controls. However, its thermostat uses relatively simple on/off control, so it is important that the installer confirms this approach suits the heat pump design. Domestic hot water normally remains under the heat pump manufacturer’s own controller.

Why we recommend it: if you already own Hive products, replacing the whole ecosystem may make little sense. But we would not choose Hive purely because it is the most familiar brand.

Best for you if: you already use Hive and your installer is satisfied that simple external room-demand control will work correctly alongside the heat pump’s own weather compensation and system controls.
