The Hive vs tado° vs Nest thermostat question comes up constantly in UK smart-home forums — and for good reason. All three brands dominate the UK market, all three work with the combi and system boilers found in most British homes, and all three promise meaningful energy savings. But under the surface they target quite different households. Hive leans on the British Gas installer network; tado° is the multi-zone specialist; Nest excels at set-it-and-forget-it automatic scheduling. Read on for a full breakdown.
At a Glance: Quick Comparison
Before diving into detail, here is how the three brands stack up on the factors most UK buyers care about:
- Hive Active Heating — around £179 for the hub and thermostat starter kit; optional subscription for advanced features; boiler-only control in the base kit (no TRVs); largest UK installer network via British Gas.
- tado° V3+ — around £99.99 for the wireless starter kit; TRV expansion modules available; Auto-Assist geofencing subscription at £2.99 per month; works with Apple HomeKit, Alexa and Google Home.
- tado° X — around £149.99; Matter-compatible (launched 2024); same ecosystem as V3+ but future-proofed for the open smart-home standard.
- Google Nest Thermostat (4th gen) — around £119.99; requires a C-wire or the Nest Power Connector; ENERGY STAR certified; no TRV support.
- Nest Learning Thermostat (3rd gen) — around £219.99; learns your schedule automatically over the first week; works with Alexa and Google Home.

Hive Active Heating
Best for: British Gas customers and anyone who wants a professional installation.
Hive is owned by British Gas and benefits from the largest heating-engineer network in the country. If you want a professional to handle the wiring and commissioning, Hive is the easiest path — British Gas engineers install it routinely, and the Hive app walks you through pairing in minutes afterwards.
The starter kit (hub plus wireless thermostat) typically costs around £179 and can be self-installed, though many buyers opt for the paid installation service for peace of mind. The Hive Hub connects to your router and acts as the bridge between the thermostat and the Hive cloud. Unlike tado°, which is wireless throughout, the Hive Hub does require a mains socket near your router.
The base subscription is free and covers scheduled control, manual boosts, and remote access via the Hive app. A Hive Heating Plus subscription (pricing varies) unlocks multi-zone heating, Autumn and Spring modes, and more granular usage reporting. Hive works with both Amazon Alexa and Google Home for voice control.
Limitations: the base Hive kit controls your boiler only — there are no Hive TRV (thermostatic radiator valve) products, so you cannot set different temperatures room-by-room without a full multi-zone system. If per-room control matters, tado° is a better fit. Read our full Hive Active Heating review for installation detail and long-term performance notes.
tado° V3+ and tado° X
Best for: multi-zone heating with TRVs and Apple HomeKit users.
tado° is the go-to choice for UK households that want genuine room-by-room temperature control. The brand's Smart Radiator Thermostats (TRVs) fit most standard radiator valve bodies and connect wirelessly to the tado° internet bridge. You can add as many TRVs as you have radiators, setting individual schedules and temperatures for each room from the app.
The V3+ wireless smart thermostat starter kit costs around £99.99, making it the most affordable entry point of the three brands. The Auto-Assist subscription, at £2.99 per month (or around £24.99 per year), adds automatic geofencing — your heating adjusts based on whether household members are at home — and open-window detection that pauses heating when a window is left open.
Without Auto-Assist, geofencing is manual: you tap a button in the app when you leave. Which? has noted that the free tier is still functional for most households, but the subscription adds measurable energy savings for busy families. The tado° app also shows a daily energy IQ score and estimated savings, giving clear feedback on system performance.
tado° X, launched in 2024 at around £149.99, adds Matter support. Matter is the industry-standard smart-home protocol backed by Apple, Google, Amazon and Samsung, meaning a tado° X system can be controlled natively from Apple Home, Google Home or Amazon Alexa without relying solely on the tado° cloud. For households building a wider smart-home setup, the X generation is worth the extra cost.

Google Nest Thermostat
Best for: hands-off auto-scheduling and Google Home households.
Google offers two thermostats in the UK: the 4th-generation Nest Thermostat (around £119.99) and the Nest Learning Thermostat 3rd generation (around £219.99). Both live entirely within the Google Home ecosystem and integrate tightly with other Nest and Google devices.
The Nest Learning Thermostat is the headline product: it watches when you manually adjust the temperature and builds a schedule automatically over the first week. Most households find they barely need to open the app after the first fortnight. It also detects when the home is empty (via your phone's location) and enters Eco mode, reducing energy waste without any manual input. ENERGY STAR certification means it meets strict energy-efficiency criteria defined by the US EPA, though the thermostat is fully optimised for UK heating systems and works with Alexa as well as Google.
The 4th-generation Nest Thermostat is the budget option at around £119.99. It drops the learning algorithm but retains remote scheduling, Eco mode and the clean mirror-glass display. One important caveat: Nest thermostats require a continuous-live (C-wire) connection to your boiler wiring — if your boiler does not have a C-wire, Google sells a Nest Power Connector adapter, though compatibility varies by boiler model.
Limitations: Neither Nest thermostat supports TRVs. Google has no radiator valve product, so Nest is a whole-home solution only. It is also the only brand here that does not support Apple HomeKit. If your household is invested in the Apple ecosystem, tado° is the better choice. Our Nest Learning Thermostat UK review covers installation and auto-scheduling in detail.
Installation and Compatibility
All three brands are compatible with the UK's most common boiler types:
- Combi boilers — fully supported by Hive, tado° and Nest
- System boilers with a hot water cylinder — supported; Hive and tado° can also control the hot water circuit
- Heat pumps — tado° X has the broadest heat-pump compatibility via its Matter integration and dedicated heat-pump thermostat variant
Self-installation is straightforward for all three if you are replacing an existing programmer/thermostat — typically 30–60 minutes with a screwdriver. Hive and tado° are wired to the boiler's existing connections; Nest may require a C-wire adapter on older boilers. If in doubt, all three brands offer professional installation services.
Smart Platform Compatibility
| Brand | Alexa | Google Home | Apple HomeKit | Matter |
|---|---|---|---|---|
| Hive | Yes | Yes | No | No |
| tado° V3+ | Yes | Yes | Yes | No |
| tado° X | Yes | Yes | Yes | Yes |
| Nest (4th gen) | Yes | Yes | No | No |
| Nest Learning | Yes | Yes | No | No |
Ongoing Costs and Subscriptions
Subscription costs are where the three brands diverge most sharply. Nest charges nothing after purchase — all features are included. tado° offers a fully functional free tier but gates geofencing and open-window detection behind the Auto-Assist subscription (around £2.99/month or £24.99/year). Hive's Heating Plus subscription unlocks multi-zone modes; the exact price varies, so check the Hive website for current pricing.
Energy Saving Trust research suggests smart thermostats can cut heating bills by around £75–£150 per year for a typical UK home, though actual savings depend heavily on your existing controls, boiler efficiency, and how well you use the system's smart features. See our article on whether smart heating is worth it in the UK for a full payback calculation.
Which One Should You Buy?
The right choice depends on your household's priorities:
- Choose Hive if you are a British Gas customer, want the largest installer network, or prefer a brand with strong UK customer support and no mandatory subscription.
- Choose tado° V3+ if you want to add TRVs for room-by-room control, use Apple HomeKit, or want the lowest upfront cost.
- Choose tado° X if you are building a broader smart-home setup and want Matter compatibility for long-term platform flexibility.
- Choose Nest Learning Thermostat if you want a truly hands-off system that learns your schedule automatically and you are already in the Google Home ecosystem.
- Choose Nest Thermostat (4th gen) if budget is a priority and you do not need auto-scheduling or TRV support.
