Smart thermostats have become an essential part of modern smart homes, offering convenience, energy efficiency, and remote control over heating systems. In the UK, where gas boilers are the predominant heating method, choosing the right smart thermostat can make a noticeable difference in comfort and cost savings. These devices replace traditional thermostats by connecting to your heating system and allowing you to schedule, monitor, and adjust temperatures from your smartphone or voice assistant.
Two of the most popular smart thermostats in the UK market are Hive and Tado. Both claim to improve heating control and reduce energy bills but differ in their features, compatibility, and pricing. For UK homeowners, understanding how these devices work with various types of boilers and heating setups is crucial.
When selecting a smart thermostat for a UK boiler, compatibility with your existing system is the most important consideration. Look for support regarding combi, system, or conventional boilers. Other critical factors include ease of installation, app functionality, and integration with third-party smart home platforms. We spent time analysing the Hive and Tado smart thermostats to find out which works best for UK boilers and homeowners seeking greater control and savings.
Best Smart Thermostats for UK Boilers
We have reviewed the top smart thermostats designed for UK boilers to help you make an informed decision. Our list compares Hive and Tado models based on features, compatibility, and ease of use. These options offer reliable performance for a smarter home heating experience.
tado Smart Thermostat X Starter Kit
This thermostat offers reliable smart heating control for UK boilers, with strong energy-saving features and easy app operation.
Pros
- Effective multizone temperature control via app and voice assistants
- AI-driven energy savings including geofencing and open window detection
- Straightforward DIY installation with clear instructions
Cons
- Requires the Bridge X for full functionality and smart home integration
- Not compatible with older tado models (V3+ and below)
- Some users may find installation daunting without basic wiring knowledge
We found the tado Smart Thermostat X to be simple to set up thanks to its well-documented guide and included hardware. The ability to control heating and hot water from the app or voice commands made daily adjustments effortless.
Its AI Assist feature helps optimise heating schedules around our routines, noticeably reducing unnecessary energy use. The multi-room temperature management is particularly useful for avoiding heating unused areas.
On the downside, the thermostat depends on the Bridge X to unlock all smart home features, which is included but adds complexity. Also, if you have an older tado system, this model won’t connect with those devices. Overall, it’s a solid choice for modern boiler control with smart home compatibility.
tado° Starter Kit – Wireless Smart Thermostat V3+
This thermostat suits anyone wanting smart heating control that’s easy to install and delivers reliable performance with UK boilers.
Pros
- Intuitive app control with real-time heating adjustments
- Smart notifications for open windows and no-one-home detection
- Voice assistant compatibility for Alexa, Siri, and Google
Cons
- Connectivity issues reported with some boiler types
- Extra fees for optional Auto Assist features
- Slight learning curve during initial setup
We found the tado° system straightforward to install, even on an older boiler, thanks to clear, tailored instructions. The wireless receiver and app interface give full control over heating and hot water, which helped us reduce unnecessary energy usage.
The geofencing and open window detection features genuinely cut down on wasted heating hours. However, a few connection drops with the wireless link to the boiler meant troubleshooting was sometimes necessary.
The app is responsive, and its heating boost option is very handy for quick warmth in all rooms. Overall, it’s a solid choice where precise temperature control and energy savings are priorities without a complicated setup.
tado° Smart Thermostat Starter Kit V3+
If you’re after precise smart heating control that works reliably with most UK boilers, the tado° Starter Kit is worth considering.
Pros
- Intuitive app control lets us adjust heating from anywhere
- Supports a wide range of UK heating systems including gas and oil boilers
- Automatically reminds us to reduce heating when windows are open or no one’s home
Cons
- Full automation features require a paid subscription
- Setup can be fiddly depending on existing boiler wiring
- Some functions need additional smart thermostats for multi-room control
From our experience, the tado° app gives excellent control options. We can schedule heating room-by-room or activate a quick boost to warm everything up fast, which is handy on chilly mornings. It’s also reassuring to get push notifications when windows are left open, helping save energy.
The compatibility is broad, so it fitted smoothly with our gas boiler system without needing extra hardware. The reminder alerts and optional Auto Assist subscription make it smarter in managing heating when the house is empty. However, setting it up took a bit of patience on our older wiring.
In sum, this thermostat blends intelligent heating management with flexible controls. It performs well in everyday use but is best suited for those happy to invest some time initially and potentially subscribe to unlock full automation.
tado Smart Thermostat X
We find the tado Smart Thermostat X a strong choice for wired heating control in UK homes that want straightforward, energy-efficient management via app or voice.
Pros
- Easy DIY installation and setup with clear instructions
- Works well with multiple smart assistants including Alexa, Siri, and Google
- AI-driven features like Geofencing and Open Window Detection increase savings
Cons
- Requires the Bridge X for Thread and Matter support, sold separately
- Not backward compatible with older tado models (V3+ and before)
- Battery life can be limited compared to mains-powered alternatives
When we installed the tado Smart Thermostat X, the process was remarkably simple, even for someone with basic DIY skills. The step-by-step manual and wired installation made it clear how to connect it to a compatible gas boiler or heat pump.
Controlling the heating via the app delivers precise temperature adjustments, and we appreciated how it integrates seamlessly with voice commands through Amazon Alexa and other assistants. The display is intuitive, making manual control quick if needed.
The AI Assist functionality impressed us by optimising heating schedules based on our patterns, which could lead to significant energy savings over time. However, the reliance on a separate Bridge X unit for the latest smart home protocols is a slight drawback that adds to the setup cost and complexity.
tado Smart Radiator Thermostat 4-Pack
This smart radiator valve add-on is ideal for those wanting granular heating control room by room with an established tado system.
Pros
- Easy, DIY installation with clear app guidance
- Enables individual room temperature adjustments via smartphone
- Compatible with most UK radiator valves using included adapters
Cons
- Requires a tado Starter Kit to operate
- Some units may occasionally face connectivity issues
- Batteries included but may need replacement sooner than expected
We found the installation straightforward, simply unscrewing old TRVs and replacing them with these smart valves. The app guides the process well, even for those less tech-savvy, allowing quick setup of heating schedules tailored to each room’s use.
Controlling heating per radiator significantly improved comfort and efficiency in our home. Being able to adjust temperatures remotely was a decisive advantage during cold days when we forgot to preheat rooms.
Some connectivity hiccups did occur, notably with units struggling to maintain WiFi at times, but these were isolated cases. Overall, the tado smart radiator thermostats offer a practical way to save on heating costs and up the smart home convenience if you already own a tado starter kit.
Buying Guide
When selecting a smart thermostat for UK boilers, we focus on compatibility first. Check if the device supports your specific boiler type—combi, system, or conventional. Ensuring proper integration helps avoid installation issues and guarantees efficient control.
Next, consider the ease of installation and setup. Some products offer straightforward DIY options, while others might require professional help. We suggest choosing one that fits your comfort level with smart home technology.
Features play a critical role. Look for:

| Price & savings | Upfront cost vs efficiency benefits | Budget-friendly and cost-effective |
We recommend weighing these aspects to find a thermostat that suits our needs and home setup best.
