Tado X outpaces Evohome on smart heating, but Honeywell still makes the stronger no-subscription case

Tado X offers quieter hardware, simpler installation and more capable automation, while Honeywell Evohome remains a compelling one-off purchase for larger, more complex multi-room heating systems.

Tado X and Honeywell Evohome remain the most prominent names in multi-room heating, but they serve different priorities. The Ambient’s testing suggests that Tado X is the more modern system, with a cleaner app, quieter hardware and stronger automation, while Evohome still appeals to buyers who want a one-off purchase and a long-established platform. Other comparisons from Powering Homes, Comparer Autrement and Smart Home Junkie broadly support that split, with Tado X framed as the more streamlined DIY option and Evohome as the more mature but older-feeling system.

On hardware and installation, Tado X is the more polished product. Its smart radiator thermostats have rotating displays that remain legible at awkward angles, and the rechargeable USB-C battery packs avoid the repeated cost and waste of disposable batteries. The Ambient also notes that the units operate almost silently, which matters in bedrooms and at night. Evohome, by contrast, uses bulkier controllers and louder radiator valves, and its interface feels dated by comparison. Both systems can handle underfloor heating through additional hardware, while Evohome offers a more specialised manifold option for complex setups.

The installation experience is another clear dividing line. Tado X is designed for self-installation, with adaptors supplied in the box and app-based guidance that walks the user through wiring and setup. Once fitted, the thermostatic heads calibrate themselves and extra rooms can be added by scanning the Matter code. Evohome can also be installed by competent users, but Honeywell recommends professional fitting, and zone configuration is more awkward, with changes buried in menus. Reports from other review sites also underline that Evohome can scale to 12 zones, which makes it attractive for larger homes, but that flexibility comes with more complexity.

Pricing is less straightforward. Tado X has a lower entry price for a starter kit, but its radiator thermostats cost more individually, and the most useful automation features sit behind a £29.99 annual subscription. Evohome has cheaper individual radiator heads and no recurring fee for its core functions, but the upfront cost of the controller, boiler switch and additional thermostats rises quickly. The Ambient’s testing suggests that a full-house Evohome build can end up expensive, while Tado X’s modular approach lets buyers begin with a few rooms and expand later. That said, Evohome keeps the appeal of paying once and owning the system outright.

Functionally, Tado X is the more advanced platform. Its adaptive heating features learn how each room behaves, it can adjust for open windows and geofencing, and changes in the app are pushed almost immediately over Thread. Evohome still handles scheduling well and remains capable for basic room-by-room control, but it lacks built-in geofencing and its updates can take noticeably longer to apply. Smart Home Junkie and other reviewers also point to Tado X’s support for Matter and broader platform compatibility, although the Matter setup can be tedious when each device must be paired separately.

Evohome retains one advantage that matters to some buyers: its integrations can be more practical in day-to-day use, particularly through Alexa and Google Assistant. The Ambient found that voice control can handle whole-house heating and multi-zone routines more naturally on Evohome than on Tado X’s Matter link, which does not handle system-wide mode changes as well. Even so, the broader conclusion is that Tado X is the stronger choice for most people who want modern controls, easier installation and quieter hardware, while Evohome remains a credible option for those who prefer a one-time purchase and do not mind older software and a more involved setup.
