Why is Nest no longer available in the UK?
Google confirmed in April 2025 that it would not develop new Nest thermostat hardware for Europe, citing the fragmented mix of boiler protocols, wiring standards and hybrid zoning systems found across European homes compared with the more standardised US HVAC market. The existing 3rd-generation Nest Learning Thermostat and Nest Thermostat E remained on sale in the UK only while stock lasted, with no successor model announced. Google also confirmed that first- and second-generation Nest thermostats lost remote app control on 25 October 2025, when the legacy Nest app retired in favour of Google Home — those older units still work, but only via the physical dial on the wall. As a goodwill gesture, Google partnered with tado to offer existing Nest owners a discount on a tado replacement, which is one signal of who Google itself considers the closest alternative.
Which thermostat is the closest match to Nest?
The tado° X is the closest match to Nest for most UK homes, because it shares Nest's touch-display, phone-based geofencing and mainstream ecosystem support (Apple Home, Google Home, Amazon Alexa) while adding OpenTherm boiler modulation Nest never offered in Europe. tado has been expanding its UK retail presence specifically to absorb ex-Nest customers, and the X range runs on Matter and Thread rather than a proprietary cloud bridge, which means Home Assistant users get a local API instead of the cloud-only control Nest required.
How did we choose these Nest replacements?
Every pick below had to be currently on sale from a UK retailer, compatible with a standard UK combi, system or regular boiler (not a US-style forced-air furnace), and either OpenTherm-capable or otherwise able to modulate rather than simply cycling the boiler on and off. We also checked each brand's Home Assistant integration status, since that's a common reason Nest owners are shopping for an alternative rather than switching to another Google Home product. We excluded thermostats still in pre-order or without confirmed UK stock, and we didn't rank options requiring a mandatory ongoing subscription just to control the boiler.
What are the best Nest thermostat replacements for UK homes in 2026?
1. tado° X — best overall replacement
Who it's for: anyone replacing a single-zone Nest on a combi boiler who wants the closest look and feel, plus better boiler modulation.
The tado° X Wireless Starter Kit currently costs £129.99 in the UK (down from £159.99 list) and includes the Bridge X, which acts as a Thread border router as well as an internet bridge. Unlike the older tado° V3+, the X range supports OpenTherm out of the box on boilers that offer it — common on Vaillant ecoTEC, Ideal Vogue, Worcester Bosch Greenstar and Baxi Platinum models — letting the boiler modulate its flow temperature instead of simply switching on and off. Core scheduling, manual control and OpenTherm modulation work without any subscription; the optional tado° AI Assist tier (£3.99/month) adds geofencing automation and energy reports on top, but isn't required to heat your home. For Home Assistant users, tado X integrates natively over Matter with local control, avoiding the cloud round-trip Nest always required in Europe.
The catch: the full starter kit with hot water control costs more than a bare-bones Hive, and if your boiler doesn't support OpenTherm you'll only get relay (on/off) control, which narrows the advantage over cheaper rivals.

2. Hive Thermostat Mini — best budget pick
Who it's for: Nest owners who mainly used the app to nudge the temperature up or down and don't need OpenTherm modulation.
At £79 (£71.10 for Hive+ members), the Hive Thermostat Mini is the cheapest like-for-like Nest replacement that still gets a proper smartphone app, geofencing-style scheduling and voice assistant support. It works with most gas and LPG combi boilers, oil boilers that already have a room thermostat, and electric boilers with standard controls — though it's not compatible with heat pumps, solid-fuel systems or a handful of specific Worcester Bosch and Vaillant control setups, so check compatibility before buying. Core heating control needs no subscription; Hive+ (£3.99/month) is optional and adds Budget Tracker and Saver Mode rather than gating basic functionality. Hive's Home Assistant integration has shipped in HA core since 2017, maintained by community contributors rather than British Gas itself, but in practice it's stable and widely used by UK households.
The catch: no native OpenTherm support, so you lose the modulation efficiency gains tado and Wiser offer on compatible boilers.

3. Drayton Wiser — best for multi-zone and radiator-level control
Who it's for: larger homes wanting to heat individual rooms separately rather than the whole system as one zone, which Nest never properly supported in the UK.
Drayton Wiser's one-channel Thermostat Kit costs £98.98 at Screwfix (RRP £119.99), and the range scales up to multi-room kits with Smart Radiator Thermostats for room-by-room control — something the single-zone Nest Learning Thermostat couldn't match. On boilers with an OpenTherm terminal, the included Communication Module (bundled with the HubR) lets Wiser modulate flow temperature the same way tado does. Wiser supports Matter, Thread and all three major voice assistants, and our full Drayton Wiser review covers zoning setup and running costs in more detail.
The catch: Wiser's own app is less polished than tado's or Hive's, and full multi-zone kits cost significantly more than the entry-level single kit once you add radiator valves.
4. Heatmiser neoHub Mini OT — best for underfloor heating and large homes
Who it's for: homes with underfloor heating loops or more than four heating zones, where Nest was never a realistic option.
The neoHub Mini OpenTherm kit costs £144–£149.99 depending on retailer and supports OpenTherm boiler modulation alongside multi-zone control for radiators and both electric and water underfloor heating — a combination none of the other picks here handle natively. Heatmiser Neo works with Alexa, Google Home, HomeKit and IFTTT out of the box; Home Assistant support comes via a community-maintained integration on GitHub rather than an official one, so it's a slightly more hands-on setup than tado or Hive.
The catch: it's the most expensive single-zone entry point on this list, and the Home Assistant integration isn't officially supported by IMI Heatmiser.

Who should skip a Nest replacement altogether?
Skip buying a replacement now if your Nest is a working 3rd-generation Learning Thermostat or Nest Thermostat E, since Google has confirmed these keep receiving security updates and app control for the time being — there's no functional reason to rip out a device that still works normally. It's also worth skipping a full thermostat swap if your real complaint is Google Home app performance rather than the hardware itself; in that case, revisiting your automations or moving control to Home Assistant may fix the annoyance without a purchase.
Should you just keep using your existing Nest?
If your Nest thermostat is a 3rd-generation Learning Thermostat or Nest Thermostat E bought recently, you don't need to replace it immediately — Google has said these will keep receiving security updates and app control for now, and the discontinuation only affects new sales and older 1st/2nd-generation hardware. Replace it now if your Nest has already lost remote control, if you want OpenTherm modulation to cut gas use, or if you're moving to Home Assistant and want local control instead of a cloud dependency that Google could withdraw again.
