Smart homeGuides

Every smart home guide in one place

Smart home UK buyers have never had more choice, and never had a harder time working out which box does what. Matter was supposed to settle it. Instead there are three apps worth living in, two radio standards underneath them, and a lot of packaging that says "works with everything" while the small print says otherwise. So everything I have tested and priced sits here, grouped by what you are actually trying to do.

Start here

Building your first smart home

One decision comes before every purchase: whose app you want to open when a lamp will not turn off. These two answer that, and what it costs.

Best smart home starter kit UK Three routes in, priced side by side, and the Matter kit that stays put when you change your mind. Start here. Best smart speakers UK HomePod, Sonos and Echo on sound rather than hub duty, with the stereo and multi-room rules for each.
Lights, plugs and switches

The cheap bits that do the most

A plug and two bulbs change a house more than a £1,000 robot does. These are the ones I have actually run.

Best smart plugs UK Four plugs compared on price, energy monitoring and which platforms they join without a hub of their own. Tapo P110M review The £9.99 Matter plug I use most, and what its energy readings are and are not good for. Hue Bridge Pro review Whether the newer Bridge is worth the upgrade, and the MotionAware catch that comes with it. Tapo P110M, the details The factual record: specs, the 2.4GHz-only radio, what is in the box and where to buy it.
Cameras, doorbells and alarms

Watching the front door

The category where the hardware is cheap and the subscription is not. Read the plan prices before you pick the camera.

Blink video doorbell review Living with Amazon's cheap doorbell: setup, battery life and what the free tier actually keeps. Blink video doorbell, the details Prices, the Sync Module, and which Alexa devices answer the door with it. Nest Protect smoke alarm The connected smoke and carbon monoxide alarm, and what it tells your phone when you are out.
Heating

Thermostats and radiator valves

The one category where a smart device can pay for itself, as long as you ignore the unsourced savings claims that fill this corner of the internet.

Hive thermostat British Gas's controller, what it costs to fit, and which plans it needs. Nest Learning Thermostat The one that learns your schedule, and what that means for a household that keeps irregular hours.
Sound and the garden

The rest of the house

Two more places a smart home reaches once the basics are running.

Echo Studio Amazon's big speaker, which is also a Thread border router, so it earns a second job. Eve Aqua tap timer A Thread device that waters the garden on a schedule, and one of the tidiest Apple Home accessories going. Best garden gadgets UK The outdoor half of the same idea, from watering to lighting, with prices checked this year.
The state of it

What a smart home UK buyer needs to know in 2026

Matter did one big thing and left one big thing alone. The thing it did: a Matter bulb, plug or sensor now joins Apple Home, Google Home or Alexa, so the app you pick is no longer a lifetime commitment. The thing it left alone: you still need a hub, and all three platforms say so on their own support pages.

Underneath Matter sit two radios. Wi-Fi carries anything plugged into the mains. Thread carries the battery things, because it is a low-power mesh, and it needs a border router. That is the detail that decides which hub you buy, and it is the one the packaging is quietest about.

So the order that works for most smart home UK setups is simple: pick the app, buy a hub that carries Thread, then buy Matter devices underneath it. Do that and switching sides later costs you one box.

How I work

How I cover smart home kit

I check every price at the retailer's own listing on the day I write it, and I date it. Compatibility claims come from the manufacturer's own specification or support pages, never from the marketing copy on the box, because those two disagree more often than they should.

Where a product has no affiliate route I say so and link it anyway. Where a category has no good UK answer, as with Matter-certified fans, I say that too rather than filling the gap with a product I would not buy.

Smart home FAQs

Do I need a hub for a smart home in 2026?

Yes. Apple, Google and Amazon each require one before their app will accept a Matter accessory, and each states it on its own support pages. What changed is that one hub now serves every brand, so you need one box rather than one per manufacturer.

Which smart home system is best in the UK?

The one that matches the phone in your pocket, because that is the app you will actually open. Alexa is cheapest to start at £54.99, Google costs £99 and includes Thread from the beginning, and Apple is £129 and the tidiest to use, although Apple sells no camera, doorbell or wall panel of its own.

What is Thread, and do I need it?

Thread is a low-power mesh for battery devices such as door and motion sensors. If you only plan on bulbs, plugs and cameras, Wi-Fi is enough. The moment you want a sensor, you need a hub with a Thread border router inside it.

Will Matter devices work if I switch from Alexa to Apple Home?

They move across. You add a Matter plug, bulb or sensor to the new app with a pairing code, and multi-admin lets it answer to both during the changeover. Own-brand cameras are the exception: Blink stays with Alexa and Nest Cams stay with Google.

How much does a first smart home cost?

About £205 for a hub, a lighting starter kit, a plug and a door sensor. The starter kit guide prices that basket on all three platforms, and the gap between the cheapest and the dearest route is roughly £30.
