Hive vs Tado vs Nest is the smart thermostat question most UK homeowners actually mean to ask, because these three brands cover almost every heating control sold here. Hive (British Gas) is the simplest and has no forced subscription. tado° X is the most automated but now needs a paid app subscription to use day-to-day. Google Nest still works well, but Google confirmed in April 2025 it’s no longer launching new Nest hardware in Europe, so what you buy today is what you’re stuck with. If you want set-and-forget automation and don’t mind £0.99–£3.99 a month, tado° wins. If you want full control with zero ongoing cost, Hive wins. If you’re already deep in Google’s ecosystem, Nest still makes sense — for now. The rest of this guide breaks down real UK prices, subscription costs, installation and which one actually saves you money on the bills that are about to go up again.

Quick Comparison: Hive vs Tado vs Nest at a Glance
tado° Smart Thermostat X currently edges this out on paper — Matter and Thread certified, the most precise temperature sensing of the three, but with a subscription now required for full app access. Hive stays close behind on reliability and value with no forced monthly cost. Nest drops to third once you weigh in Google’s decision to stop building new Nest thermostats for Europe. Here’s how they stack up.

Google Nest Learning Thermostat
Still a genuinely good thermostat and it plays nicely with Google Home and Nest cameras — but Google has stopped building new ones for Europe.
~£183.83 (Amazon UK)
Hive: Simple, Subscription-Free Heating Control
The Hive Thermostat costs £119 for the thermostat, receiver, batteries and guide (hivehome.com, checked 18 September 2026), and its core features — scheduling, Boost, Away Mode and basic Heating History — all work without ever paying a subscription. That’s genuinely unusual in 2026, when both tado° and most rivals now gate at least some app functionality behind a monthly fee.
If you want more, Hive+ costs £3.99/month or £39.90/year (hivehome.com, checked 18 September 2026) and adds Saver Mode, a Budget Tracker, Schedule Assist and 24/7 efficiency monitoring plus an extended warranty. Crucially, it’s optional — you’re never locked out of the app or the core thermostat like you are with tado°’s new Basic plan requirement. Hive also has a Mini version at £79 (heatable.co.uk, updated 27 August 2026) for a cheaper second-zone or simpler install.
Installation is where Hive asks more of you. A standard single-zone kit is DIY-friendly for most combi boiler setups, but multizone installs typically need a Hive Hub and professional fitting — commonly quoted around ~£99 (checkatrade.com/mybuilder.com cost guides, secondary sourcing, not confirmed on Hive’s own checkout). Hive doesn’t support Matter or Thread, so it won’t join a wider Matter smart home mesh the way tado° X can — worth knowing if you’re building out a broader smart home setup around Matter devices.
Pros
- Core scheduling and Away Mode never require a subscription
- Backed by British Gas — widespread UK support and engineer network
- Cheaper Mini option at £79 for extra zones
- Works with Alexa and Google Home
Cons
- No Matter or Thread support
- Multizone setups usually need a Hive Hub and a paid install
- Less precise temperature sensing than tado° X (1°C vs 0.5°C increments)
Hive isn’t available through our usual affiliate partners yet, so we’re not running a deal button on it here — but it’s a genuinely solid, fully-featured option and one of only a few smart thermostats on the market that doesn’t force a subscription on you to use the core product. Check current pricing directly on hivehome.com.
Tado: The Most Automated Option — But Now With a Subscription Catch
tado° Smart Thermostat X (Wired) Starter Kit currently costs £119.99, a 25% promotional reduction from its £159.99 RRP (shop.tado.com, checked 18 September 2026) — that’s an active sale price, not a fixed one, so it’s worth checking the live figure before you buy. What you get for that is the most capable hardware of the three here: 0.5°C temperature precision (double Hive and Nest’s 1°C steps), and it’s the only one of the three that’s Matter and Thread certified, meaning it can join a wider Matter-based smart home instead of sitting in its own silo.
Here’s the catch competitors mostly gloss over: since 19 February 2025, tado° has required a subscription just to use its own app. Without any subscription, the physical thermostat still works and can still be controlled through Apple Home, Google Home or Alexa — but the official tado° app itself is locked out. The entry-level Basic plan is widely reported at ~£0.99/month (moneysavingexpert.com forum thread, corroborated by smarthomeassistant.co.uk — tado.com’s own pricing page returned a 404 when we checked on 18 September 2026, so treat this as a well-corroborated but not primary-confirmed figure and check tado.com directly before buying). Most people end up on the fuller AI Assist tier at £3.99/month or £29.99/year (shop.tado.com, checked 18 September 2026), which unlocks geofencing, pre-heating, open window detection, weather adaptation, holiday mode and energy tracking — the automation that’s genuinely the reason to pick tado° over the other two.
Installation is self-install friendly for most combi and OpenTherm-compatible boilers, and tado°’s own smart home hub bridges over WiFi rather than needing a dedicated separate radio hub the way multizone Hive setups do. If you’re weighing this against a wider mesh WiFi or smart hub upgrade at the same time, it’s worth reading our Amazon Echo vs Google Nest UK comparison first to decide which voice ecosystem you’re building around.
Pros
- Matter and Thread certified — joins a wider smart home mesh
- Most precise temperature sensing (0.5°C)
- Genuinely useful automation: geofencing, weather adaptation, open window detection
- Self-install friendly on combi and OpenTherm boilers
Cons
- App access now requires a subscription, from ~£0.99/month upward
- Best features locked behind the £3.99/month AI Assist tier
- £119.99 is a promo price, not a guaranteed one
Google Nest: Still on Sale, But Google Has Moved On
The Google Nest Learning Thermostat (3rd Gen) is still a genuinely good bit of hardware — its learning algorithm, which builds a schedule from how you actually adjust the temperature, was arguably the feature that started this whole product category. Google’s own Store lists it at £219, with the cheaper Nest Thermostat E at £199 (homeenergyquotes.co.uk, citing a check of Google Store UK listings dated 27 July 2026). On Amazon UK, where this site links out for Nest purchases, we found the White 3rd Gen model listed at ~£183.83 with only a handful of units in stock when we checked on 18 September 2026 — cheaper than Google’s own price, but the limited stock is the real story here.
That’s because in April 2025 Google confirmed it will not launch any new Nest thermostats in Europe. It’s continuing to sell the existing 3rd-gen Learning Thermostat and Thermostat E “while supplies last,” and has said it’s instead backing specialist manufacturers — namely tado°, Hive, Drayton Wiser and Heatmiser — for the European market going forward. Support for the older 1st-gen, 2nd-gen and the 2014 EU 2nd-gen models already ended on 25 October 2025, with no app or Google Home connectivity from that date. No end date has been announced yet for 3rd-gen or Thermostat E support, but buying into a product line the manufacturer has publicly stepped back from is a real consideration, not a hypothetical one.
If you already run an Alexa or Google Home smart home, it’s worth reading how Nest fits against the wider ecosystem in our Amazon Echo vs Google Nest UK comparison before committing — particularly if voice control and integration with Nest cameras or speakers matters more to you than long-term hardware support.
Pros
- Learning algorithm builds a schedule automatically from your habits
- No mandatory subscription for core thermostat function
- Tight integration with Google Home, Nest cameras and speakers
- Polished, well-understood app and interface
Cons
- Google has stopped launching new Nest thermostats in Europe
- UK stock is genuinely limited, pushing some Amazon listings higher
- No Matter or Thread support on the 3rd-gen model
- Long-term software support beyond the current generation is unconfirmed
Hive vs Tado vs Nest: Full Spec and Price Comparison

Which Smart Thermostat Is Right for You?
With only three real options in this comparison, the right pick comes down to how you feel about subscriptions, how automated you want your heating to be, and which smart home ecosystem you’re already invested in.
Best for simplicity and no subscription: Hive
If the idea of another monthly bill for something as basic as adjusting your heating annoys you, Hive is the obvious pick. Scheduling, Boost and Away Mode all work without ever paying Hive a penny beyond the £119 hardware cost, and British Gas’s UK-wide support network means help is easy to find if something goes wrong.
Best for multi-room, zoned homes: Tado
tado°’s smart radiator valves and geofencing make it the strongest option if you’re heating a larger home in zones and want the system to actually adapt to who’s home and the weather outside. Just budget for the ongoing app subscription on top of the £119.99 hardware.
Best if you’re already deep in the Google ecosystem: Nest
If your home already runs on Google Home, Nest cameras and Nest speakers, the Learning Thermostat still slots in neatly and the learning algorithm remains genuinely useful. Just go in aware that Google has stepped back from this product category in Europe, and current UK stock is limited enough that prices vary noticeably between retailers.
Best if you want zero ongoing subscription commitment at all: Hive
Of the three, only Hive guarantees its core functionality stays free indefinitely — Nest doesn’t force a subscription either today, but tado°’s February 2025 change shows how quickly that can shift. If avoiding recurring costs is your main priority, Hive is the safer long-term bet.
General self-install steps, whichever you choose:
- Turn off power to your boiler at the fuse box before removing your existing thermostat or wiring centre cover.
- Check your boiler is combi, system or conventional, and confirm OpenTherm compatibility if you’re fitting tado° X.
- Fit the receiver or bridge close to your boiler or wiring centre, following the manufacturer’s wiring diagram exactly.
- Mount the thermostat unit itself somewhere central, away from direct sunlight or draughts, and pair it with your home WiFi.
- Run the app’s setup wizard to confirm heating schedules, then test a full heating cycle before considering the job done.
If any of that sounds daunting, all three brands offer or recommend professional installation — worth the ~£99 typical cost if you’re not confident working near your boiler’s wiring.
How Much Could You Actually Save on Heating?
Ofgem confirmed the energy price cap will rise by 4% from 1 October 2026, taking a typical dual-fuel direct-debit household from £1,663/year to £1,723/year — an extra £60/year (ofgem.gov.uk press release, checked 18 September 2026). That makes any genuine heating saving worth more this winter than last.
Manufacturer marketing for all three brands claims savings in the 15–30% range, but that figure comes from the companies selling the product, not independent testing, so treat it as a ceiling rather than an expectation. We haven’t independently verified a specific lower real-world figure this session, and won’t quote one without a named, dated source behind it — if you see a site claiming an exact “X% saving” number without saying who measured it and when, be sceptical of it. What we can say with confidence: smart scheduling that actually reduces how long your heating runs when nobody’s home — rather than a dumb timer left running all day — is where the genuine saving comes from, regardless of which of these three you pick. Geofencing (tado°) and Away Mode (Hive, Nest) both do this automatically; a dumb thermostat only does it if you remember to change it yourself.
If you’re weighing this purchase against other smart home spending, our smart home cost UK guide breaks down what each tier of setup — from a single smart plug to a full house — actually costs to run.
Frequently Asked Questions
Which is better for saving money on energy bills — Hive or Tado?
Both can reduce wasted heating through scheduling and Away Mode, and neither brand’s marketing savings figures are independently verified, so there’s no honest answer that names a clear winner on bill savings alone. tado°’s geofencing automates “heating off when nobody’s home” more completely than Hive’s manual Away Mode, which may matter more in practice than the headline percentage either brand advertises.
Does Tado still need a subscription to use in the UK?
Yes. Since 19 February 2025, tado° has required a paid Basic plan (widely reported at ~£0.99/month) just to use the official tado° app. Without any subscription, the physical thermostat still works and can be controlled through Apple Home, Google Home or Alexa, but the tado° app itself is locked out.
Is the Google Nest thermostat still available to buy in the UK?
Yes, the Nest Learning Thermostat (3rd Gen) and Nest Thermostat E are still on sale in the UK through Google’s Store and retailers including Amazon, but Google confirmed in April 2025 it won’t launch any new Nest thermostat hardware in Europe. Current stock is being sold “while supplies last,” and UK availability is already visibly limited on some retailers.
Which smart thermostat is easiest to install yourself?
tado° Smart Thermostat X and the Google Nest Learning Thermostat are both generally rated as the most DIY-friendly for a straightforward single-zone combi boiler setup. Hive is also self-install friendly for a single zone, but multizone Hive installs typically need a Hive Hub and are more commonly professionally fitted.
Do I need a British Gas (or other professional) engineer to install Hive?
Not necessarily. A standard single-zone Hive Thermostat is designed for DIY installation on most combi boilers. Professional installation is more common — and often recommended — for multizone setups that need a Hive Hub, and typically costs around ~£99, though this figure comes from third-party cost-guide sites rather than Hive’s own checkout.
Which smart thermostat works best with Alexa and Google Home?
All three — Hive, tado° and Google Nest — work with both Alexa and Google Home. tado° additionally supports Apple Home, which neither Hive nor Nest offer, making it the strongest pick if you’re using Apple’s smart home app alongside Alexa or Google Home.
Is Hive or Tado better for a combi boiler or OpenTherm setup?
Both Hive and tado° work with combi boilers. tado° Smart Thermostat X specifically supports OpenTherm-compatible boilers for smoother modulating control, which Hive doesn’t advertise in the same way — check your boiler’s own compatibility list before buying either.
How much does a smart thermostat cost to install in the UK?
Self-installing any of these three costs nothing beyond the hardware price (from £119). Professional installation, typically needed for multizone Hive setups or if you’re not confident working near your boiler’s wiring, is commonly quoted around ~£99, based on third-party cost-guide sites rather than any single brand’s official pricing.
Can I use Tado for free, without paying for AI Assist?
You can use tado° without the £3.99/month AI Assist tier, but not entirely for free — a Basic plan (widely reported at ~£0.99/month) has been mandatory for official tado° app access since 19 February 2025. Without any subscription at all, the thermostat still works but only through Apple Home, Google Home or Alexa, not tado°’s own app.
Which of the three supports Matter?
Only tado° Smart Thermostat X is Matter and Thread certified among these three. Neither the Hive Thermostat nor the Google Nest Learning Thermostat (3rd Gen) supports Matter, so if joining a broader Matter-based smart home matters to you, tado° is currently the only one of the three that fits.
Ready to Choose? Here’s Where to Buy
tado° Smart Thermostat X is currently £119.99 on a promotional price and is the most automated pick if you’re happy with the subscription. Google Nest is still available but increasingly stock-limited on Amazon UK — worth checking current availability before you commit. Hive doesn’t have a live deal link through our affiliate partners yet, but it remains the strongest subscription-free option and is easy to buy directly from hivehome.com.
Prices, subscription costs and stock levels for smart thermostats change often — every figure in this guide is dated and sourced above, and we recommend double-checking the current price on the retailer’s own page before buying.
