If you’ve been looking at smart thermostats recently, you’ve probably noticed one thing - Google Nest has effectively disappeared from the UK market.
And that leaves a pretty big question.
What replaces it?
For years, Nest was the benchmark for smart heating. It looked good, felt premium, and offered more than just basic app control. But now there’s a gap - and tado° X looks like one of the clearest attempts yet to fill it.
This is tado°’s newest smart thermostat system, built around Matter-over-Thread and designed to offer quicker response times, better connectivity, proper room-by-room control, and a more future-proof smart home setup than older generations.
But does it actually live up to the hype?
In this tado° X review, we’ll look at what it is, how it works, what installation is like, what you get for the money, and whether it’s genuinely worth buying - or just another smart thermostat with a shiny app.
What Is tado° X?
tado° X is a smart heating control system designed to give you more control over your home’s heating, whether you’ve got a boiler, heat pump, or a more complex setup with multiple radiators and zones.
And really, the easiest way to understand it is by looking at the three levels of heating control most homeowners end up choosing between.
Level 1: Basic control
This is your standard manual or programmable room thermostat. Functional, familiar, and not particularly clever.
Level 2: Connected control
This is where you get app access. You can turn your heating on and off from your phone, adjust temperatures remotely, and feel vaguely futuristic.
Level 3: Proper smart heating
This is where Nest built its reputation - and where tado° X is now aiming.
We’re talking about smart connectivity, room-by-room control, automation, learning behaviour, and actual energy-saving intelligence.
That’s what makes tado° X more interesting than a lot of cheaper competitors. It isn’t just trying to put your boiler on your phone. It’s trying to make your heating system work better.
What Comes in the Box?
The version most people will look at is the Wireless Smart Thermostat X Starter Kit.
Inside the box, you’ll typically get:
the wireless thermostat
the receiver
a mounting kit
setup instructions through the app
First impressions are strong. The packaging is clean, tidy, and properly premium - very much the sort of presentation Nest used to nail.
That matters more than people think. When you’re spending proper money on heating controls, you want it to feel like a quality upgrade, not just another plastic box for the wall.
The thermostat itself looks smart, modern, and minimal without trying too hard.
How Much Does tado° X Cost?
We paid £159 direct from tado° for the wireless version, plus £4.99 delivery, which puts it right in that premium smart thermostat bracket.
That said, we’ve also seen it drop lower during sales, with prices dipping to around £129 on Black Friday.
As a rough guide, current pricing usually looks something like this:
Wireless Smart Thermostat X Starter Kit: around £159
Wired Smart Thermostat X: around £70 to £100
Smart Radiator Thermostat X: around £60 to £80 each
Bridge X: around £50 to £60, if needed
Heat Pump Optimiser X: around £230
A single-zone setup is fairly reasonable. A whole-home setup with multiple radiator valves can get expensive quickly.
So yes, this can be a smart investment - but it definitely isn’t the bargain-bin option.
Installation: Easier Than You Might Expect
One of the biggest wins for tado° X is that installation is surprisingly approachable.
The app takes you through the process step by step, and it’s far more polished than a lot of heating products we’ve seen.
If you’re swapping out radiator valves, there’s no plumbing involved, which makes things much less intimidating. If you’re wiring in the receiver, it’s still manageable for a confident DIYer.
That said, don’t be daft - if you’re not comfortable around electrics, get a professional in.
The bigger point is that this doesn’t feel like one of those smart home products that promises simplicity then immediately sends you into a spiral of error codes and frustration.
The setup process is logical, guided, and clearly built for normal homeowners rather than tech obsessives.

The Big Upgrade: Matter Over Thread
This is the bit tado° really wants you to care about - and to be fair, it’s a meaningful upgrade.
tado° X uses Matter-over-Thread, which sounds like the sort of phrase smart home companies love because it makes normal people’s eyes glaze over.
In plain English, it means the system is designed to be:
faster
more reliable
better connected
more future-proof
Thread creates a mesh-style network between devices, which is especially useful in bigger homes.
Rather than relying on one flaky connection point, devices help strengthen the network between themselves. In practice, that means faster reactions and fewer dropouts.
Matter support also makes tado° X easier to use with platforms like:
Apple Home
Google Home
Amazon Alexa
SmartThings
That’s a real step forward from older systems that often felt more locked into their own ecosystem.
Features That Actually Matter
Plenty of smart thermostats list loads of features. Fewer make a convincing case that you’ll genuinely use them.
tado° X mostly gets this right.
[1] Smart scheduling
You can create heating schedules that actually reflect how your home works, rather than blasting the whole place at the same temperature all day.
[2] Room-by-room control
Add smart radiator valves and you can control individual rooms separately.
That’s one of tado°’s strongest selling points, especially if your home heats unevenly or you don’t want to waste money warming rooms nobody’s using.
[3] App control
You can make quick changes, boost the heating, tweak schedules, and keep tabs on what’s happening from your phone. The app is clean, clear, and easy to use.
[4] Geofencing
The system can tell when you’ve left home and reduce heating automatically.
[5] Open Window Detection
If it senses a sudden drop in temperature, it can respond accordingly rather than continuing to heat the room like nothing’s happened.
[6] Adaptive Heating
This is where tado° tries to move into “properly smart” territory. It learns how your home warms up and helps optimise timings so you get comfort without unnecessary waste.
[7] Boiler and heat pump support
tado° X works with a wide range of systems and is positioned well for homes looking beyond basic combi boiler setups.
The Catch: Subscription Features
This is where the review needs to be honest.
The hardware is good. The app is good. The system is clever. But some of the most useful automation features are behind a paid subscription.
That includes things like:
automatic geofencing
automatic open window actions
AI-powered heating optimisation
The subscription currently sits at roughly £3.99 per month or £29.99 per year, and whether that annoys you will depend on your tolerance for yet another monthly fee.
Some people won’t mind. If it saves money and removes hassle, fine.
Others will look at a £159 thermostat and fairly ask why more of that functionality isn’t included from the start.
That’s probably the biggest weakness in the whole tado° X proposition.
Everyday Performance
Day to day, tado° X is genuinely impressive.
This is where the newer tech starts to make sense. Commands are fast. Changes in the app happen quickly.
The system feels stable. And compared with older smart heating products, there’s much less sense that you’re wrestling with the technology.
The overall user experience is slick enough that it fades into the background - which is exactly what you want from heating controls.
You don’t want to think about them. You just want your house to be warm when it should be, cooler when it shouldn’t, and cheaper to run where possible.
The room-by-room control is particularly good in practice. If your home has one boiling bedroom, one freezing office, and a living room that never seems to settle, this is where tado° X starts to earn its keep.
tado° X Pros and Cons
Pros:
Premium design and packaging
Strong app experience
Fast, responsive controls
Matter and Thread make it feel genuinely modern
Excellent room-by-room heating potential
Easier setup than many rivals
One of the closest things to a proper Nest replacement in the UK
Cons:
Subscription needed for some of the smartest automation features
Can become expensive if you go all-in on multiple rooms
Not compatible with older tado° V3+ hardware
Might be more system than some smaller homes really need
tado° X vs tado° V3+
If you’re deciding between tado° X and tado° V3+, the answer is pretty straightforward.
If you’re buying new, get tado° X.
It’s quicker, better connected, more future-proof, and clearly where tado° is putting its focus.
If you already own tado° V3+ and it’s working perfectly well, the need to upgrade is much less urgent.
You’re not suddenly stuck with a bad product. But the X range is the better platform going forward, and that matters if you want the latest compatibility and best possible performance.
So the simple version is this:
New buyers: go for tado° X
Existing V3+ users: upgrade only if you want the newer ecosystem or better responsiveness
tado° X vs Hive and Nest
Against Hive, tado° X feels more advanced, more flexible, and much stronger for multi-room setups. Hive is simpler, but it doesn’t really compete on intelligence or zoning.
Against Nest, things are more interesting.
Nest used to be the thermostat everyone compared everything else to. In the UK, that’s no longer as relevant as it once was - which gives tado° X a real opening.
And honestly, if you’re asking what replaces Nest in the UK, tado° X is one of the best answers right now.
It has the premium feel, the stronger smart home compatibility, the advanced heating control, and the modern platform. Nest still has the legacy reputation, but tado° X looks much more like the product built for what comes next.
Is tado° X Worth It?
Yes - for the right home, tado° X is absolutely worth it.
It’s one of the few smart thermostats that feels like a real upgrade rather than just a connected gimmick. It looks good, performs well, and offers proper smart heating features that can genuinely improve comfort and reduce waste.
The subscription model is the only real sour note. That won’t be a deal-breaker for everyone, but it is the one thing that stops this feeling like an easy five-star recommendation.
Still, if you want a smart thermostat that offers more than basic remote control, and you’re looking for the most credible Nest alternative currently available in the UK, tado° X is right near the top of the list.
Final Verdict
tado° X is one of the best smart thermostat systems you can buy right now.
It’s polished, fast, modern, and much more convincing than the many “smart” heating products that are really just old thermostats with an app bolted on.
The install process is refreshingly simple, the controls are slick, and the room-by-room heating potential is where it really starts to shine.
Would we prefer more of the clever stuff without a subscription? Definitely.
But even with that caveat, this is still a seriously strong bit of kit - and one of the clearest answers yet to the question of what replaces Nest in the UK.
If you want smarter heating, better zoning, and a system that feels built for the next few years rather than the last few, tado° X is a very strong buy.
