Smart thermostats only pay off if they match your boiler and wiring. I’ve kept this list to three Amazon UK options that cover the common paths: a tado X wired room thermostat starter (Bridge X in the box), a tado X radiator starter when you want TRV heads first, and a Meross Wi-Fi thermostat aimed at many UK combi / underfloor setups. tado X is not compatible with older tado V3+. Always check the maker’s compatibility tool for your boiler. (Here’s how we choose products.)
-
Best full-system start: tado X wired starter + Bridge X (#1)
-
Best radiator-first start: tado X radiator starter + Bridge X (#2)
-
Best tado° add-on valve: tado° Radiator X (#6)
-
Best Honeywell wireless kit: Honeywell Home T6R (#?)
-
Best Hive Mini add-on: Hive Thermostat Mini (#?)

FAQ
Will this work with my boiler?
Only if the maker says so. Use tado’s or Meross’s compatibility checkers, and get an electrician if the wiring isn’t a like-for-like swap.
tado X or older tado V3+?
These X kits are not compatible with V3+. Don’t mix generations.
