tado Smart Radiator Thermostat X Starter Kit review
Households who want per-room heating control without replacing valve bodies or draining the system.
By Tom Calder
This starter kit swaps onto your existing radiator valve in a few minutes with no draining and no plumber, giving useful per-room scheduling from day one. The bigger savings tado advertises assume its optional AI Assist subscription, so budget for that if you want the full effect.

- Genuine DIY install — no draining or water-leak risk, and the adapters fit 'almost all' UK valve types, per tado
- Bridge X gives Thread/Matter connectivity for reliable control via the app, Alexa, Google Assistant or Apple Home
- Rechargeable USB-C battery rather than disposables, unlike most rival TRV heads
- The starter kit fits only one radiator — a typical UK home needs several more heads at full price to zone the whole house
- tado's headline 'up to 55%' and 'up to £244/year' figures are its own modelling against its free app tier, and the AI Assist features behind them cost £3.99/month
Who shouldn't buy this
Skip the starter kit on its own if you want whole-house zoning immediately — you'll need extra thermostat heads for every other radiator, and the advertised savings only apply with the paid AI Assist add-on rather than out of the box.
