Best smart radiator valves UK (2026): which need a hub, which work with Matter, and what they fit

The second-generation version of Drayton's zoning kit: a hub, a room thermostat and two smart radiator thermostats, run from the Wiser Home app. It controls a combi boiler over OpenTherm or relay and grows to 16 rooms. The listing's 'save up to 30%' is Drayton's own claim, so treat it as a ceiling: what you save depends on the home and how consistently you use the schedules.

Best for Households wanting room-by-room heating control on a combi boiler, starting with two radiators.

• No subscription fee, per the listing, for app control and schedules
• Two radiator thermostats in the box, expandable to 16 rooms and 63 Wiser devices
• Works with Alexa and Google Assistant, and the hub is a Matter bridge

• Combi boilers only — a system with a hot water cylinder needs Multi-Zone Kit 2
• The 'up to 30%' saving is Drayton's own figure, and the hub wiring at the boiler is mains work

Who shouldn't buy it: Don't buy it if you have a hot water cylinder — Multi-Zone Kit 2 adds the hot water channel. Check your radiator valves first too: if a head can't fit your valve body, the body has to be replaced, which means draining the system.

Eve's fifth-generation Thermo is a Matter-over-Thread radiator valve with touch controls on the valve itself. Eve says it works without an Eve cloud account, registration or subscription. It needs a Thread border router and a Matter controller in your home, so it suits people who already have that kind of smart home. Eve's spec list does not give the valve thread, so check your valve before buying, and note it controls radiators only, not the boiler.

Best for Households already running Apple Home, Alexa or Google Home who want local, subscription-free radiator control.

• Works with Apple Home, Alexa and Google Home through Matter
• Eve says there is no cloud, registration or subscription
• Matter 1.4.1 certificate on record for this generation

• Needs a Thread border router and Matter controller, such as a compatible speaker or streamer
• Radiator valves only: it does not control the boiler
• Each valve runs on two AA cells that need changing

Who shouldn't buy it: Don't buy it if you have no Matter hub or Thread border router and don't want to buy one, or if you need one system that also runs the boiler.

This starter kit swaps onto your existing radiator valve in a few minutes with no draining and no plumber, giving useful per-room scheduling from day one. tado's headline 'up to 55%' saving assumes its optional AI Assist subscription (£3.99 a month), so budget for that if you want the full effect.

Best for Households who want per-room heating control without replacing valve bodies or draining the system.

• Genuine DIY install — no draining or water-leak risk, and the six adapters fit 'almost all radiator valves', per tado
• Bridge X gives Thread/Matter connectivity for reliable control via the app, Alexa, Google Assistant or Apple Home
• Rechargeable USB-C battery rather than disposables; tado says a charge lasts about a year (the USB-C cable isn't in the box)

• The starter kit fits only one radiator: zoning the whole house means a head for every other radiator, and tado recommends one Bridge X per 100 m² in larger homes
• tado's 'up to 55%' figure compares its £3.99-a-month AI Assist with the free app, and its 'up to £244 a year' is its own estimate from its users' data: both are tado's modelling, not independent tests

Who shouldn't buy it: Skip the starter kit on its own if you want whole-house zoning immediately — you'll need extra thermostat heads for every other radiator, and tado's headline 'up to 55%' saving assumes the paid AI Assist add-on rather than the free app.

A tool-free way to put smart control on three radiators at once — the heads swap onto the existing valve bodies with no plumber and no draining. Budget for the hub separately: it's a heads-only pack, and tado's app control needs a Bridge X or another Thread border router to talk to.

Best for Homes on tado's X platform, or buying a Bridge X alongside, that want smart control on three more radiators in one purchase.

• Rechargeable batteries rather than disposable cells to keep replacing
• Screws onto the existing valve body — no plumber or drained system required
• Thread and Matter support, so it fits wider smart-home setups, not just tado's own app

• Bridge X (or another Thread border router) is sold separately
• Geofencing, adaptive scheduling and energy reports sit behind tado's optional AI Assist subscription

Who shouldn't buy it: Don't buy this pack on its own if you don't already have a tado Bridge X or a compatible Thread router — without one it won't connect to the tado app. It won't pair with the older V3+ system either.

Aqara's W600 runs in one of two modes. In Thread mode it joins Matter ecosystems such as Apple Home, Google Home and Alexa through a Thread border router. In Zigbee mode it needs an Aqara hub, and Aqara says that mode adds on-device schedules and the option to read temperature from a separate Aqara room sensor. The box includes six valve adaptors, which helps with fitting. Like other smart valves it controls radiators only.

Best for Smart-home users who want one radiator valve that can run on Matter or on Aqara's own Zigbee hubs.

• Two connection modes: Thread/Matter or Zigbee
• Six adaptors included, covering Danfoss, Caleffi, Giacomini and others
• Aqara quotes up to two years of battery life from two AA cells, on typical use

• Thread mode needs a Matter controller and a Thread border router
• Aqara says local schedules and the external room-sensor link need Zigbee mode with an Aqara hub
• Radiators only: it does not switch the boiler

Who shouldn't buy it: Don't buy it if you have no Matter or Aqara hub, or if you want one system that also runs the boiler and hot water.

The second-generation version of Drayton's two-channel kit: heating and hot water on separate schedules, plus two smart radiator thermostats to start zoning. It suits conventional and system boilers with a cylinder, switching by relay, and grows to 16 rooms. The value comes from actually using the schedules; left on factory settings it won't save money.

Best for Homes with a hot water cylinder wanting room-by-room heating schedules and separate hot water timing.

• Separate heating and hot water channels, each on its own schedule
• Two radiator thermostats included, expandable to 16 rooms and 63 devices
• No subscription fee, per the listing, and works with Alexa and Google Assistant

• Relay switching only on Drayton's specification — it doesn't list OpenTherm for this kit
• The hub wires in at the boiler or programmer position, which is mains work

Who shouldn't buy it: Don't buy it if you have a combi boiler — the second channel is for a hot water cylinder, so combi owners want Multi-Zone Kit 1 instead.

A straightforward DIY upgrade for anyone with existing numbered TRV heads and a compatible Hive Hub — swap the head, set a schedule per room, and stop heating rooms nobody's in. The pack-of-3 price only makes sense if you're already in the Hive ecosystem or buying in for several rooms at once.

Best for Multi-radiator households wanting room-by-room scheduling without replacing valve bodies or a full smart-thermostat rewire.

• Room-by-room temperature control and scheduling from the Hive app
• DIY swap onto existing TRV valve bodies in roughly 10-20 minutes each, with M30, M28 and Danfoss RA adaptors included
• Open-window detection and child lock built in

• Needs a current-generation Hive Hub or Hub 360 to work at all — Hub 1 isn't supported, and that's an extra cost if you don't already have Hive
• Runs on 2× AA batteries per valve, so a whole-house install means an ongoing battery-swap routine across multiple rooms

Who shouldn't buy it: Don't buy if your radiators only have plain manual on/off valves (no numbered dial), or if you're not sure of your valve body — the included M30, M28 and Danfoss RA adaptors cover most UK valves but not every one, so check before ordering. Also don't buy if you don't already have, or want, a compatible Hive Hub: the pack price assumes you do, and adding a Hub on top pushes out the payback.

A straightforward DIY way to bring room-by-room scheduling to extra radiators on tado's older V3+ platform — but it's an add-on only, with no bridge in the box, so check what you already own before buying.

Best for Households that already own a tado V3+ (or V2/V3) starter kit and want per-room control on three more radiators.

• Fits most existing valves directly or with one of the six adapters supplied per head
• Gives proper per-room scheduling once paired with an existing tado starter kit
• Works with Alexa, Siri and Google Assistant, per the listing

• Needs an existing tado V2, V3 or V3+ starter kit — it does nothing on its own and won't pair with tado's newer X system
• Legacy V3+ generation with no upgrade path to tado X, running on AA batteries rather than the X range's rechargeable cells

Who shouldn't buy it: Don't buy this pack as your first tado purchase — it only works with an existing tado V2, V3 or V3+ starter kit — and don't expect it to pair with a tado X Bridge.

The KE100 is a battery-powered radiator valve that talks over 868 MHz radio to a separate Kasa KH100 hub, which is not in the box with this listing. Through the Kasa app it offers schedules, grouping and temperature control, and the listing names Alexa and Google Home support. It is an add-on rather than a whole heating system: TP-Link says it controls radiator valves only and cannot run the boiler or a central thermostat.

Best for Budget-minded households wanting simple app schedules per radiator and already using or happy to add a Kasa hub.

• TP-Link says one pair of AA cells lasts a heating season
• Adaptors for Danfoss RA, RAV and RAVL valve types come in the box
• Listing names Alexa and Google Home support

• Needs a Kasa KH100 hub, bought separately with this listing
• Does not control the boiler or a central thermostat
• Manual knob adjusts in whole 1 C steps

Who shouldn't buy it: Don't buy it if you need Apple Home or Matter, which TP-Link's listing doesn't name, or if you don't want an extra hub.

A tidy, tool-free upgrade for existing Hive households with TRV valve bodies already fitted — the head swaps on in minutes with no plumbing involved, and each radiator gets its own schedule. Manual valves need the head-and-body version instead, which does involve draining the system. It's an add-on, not a starting point, so it only earns its keep once a current Hive Hub (or Hub 360) is already running.

Best for Households already on the Hive ecosystem who want to heat room-by-room instead of the whole house to one setting.

• No tools or plumber needed if a TRV valve body is already fitted — old head unscrews, new one hand-tightens on in around 10-20 minutes
• Room-by-room scheduling and boost via the Hive app rather than one setting for the whole house
• Works with any plumbed radiator system that has TRV bodies fitted — no Hive thermostat or Active Heating required on top of the hub

• Tied to the Hive ecosystem — needs a current Hive Hub or Hub 360 already running to do anything, so it's not usable standalone
• Five battery-powered heads (2x AA each) to keep topped up rather than one central thermostat

Who shouldn't buy it: You don't already have a current Hive Hub or Hub 360 running — the original Hive Hub 1 doesn't support radiator valves, so check your hub generation before buying. A separate Hive thermostat or Active Heating isn't required.
