Smart Home: The First Five Things Worth Buying — key points at a glance
Published 17 September 2026 · updated 2026-09-17 · by GimmickHub
Short answer: The five smart home devices worth buying first are Matter-compatible smart plugs, an energy-monitoring outlet, a motion sensor, smart bulbs, and a voice assistant. Start with two plugs under £15 each — look for 15A/1800W rating and Matter certification — then add a motion sensor and bulbs as you build out automations.
Most people who regret their smart home start bought the wrong device first — a £200 smart display used as a clock, or a subscription-locked gadget that stopped working after eighteen months. The first five smart home things worth buying are Matter-compatible smart plugs, an energy-monitoring outlet, a motion sensor, smart bulbs, and a voice assistant. Every one is available for under £30.
Why Smart Plugs Are the Best First Smart Home Purchase
Smart plugs are the lowest-risk, highest-return entry point into a connected home. You don't need to replace any appliance, run a single cable, or call an electrician. Push the plug into a standard 13A UK wall socket, connect the appliance you already own, and you have remote on/off control, scheduling, and — with the right model — real-time energy monitoring.
The technology gap between a £10 smart plug and a £25 smart plug has narrowed considerably. The key differentiator now is ecosystem compatibility, not basic function.
Matter: The One Protocol Worth Understanding
Matter is a universal smart home standard developed jointly by Apple, Google, Amazon, and Samsung. A plug certified for Matter works simultaneously with Apple Home, Siri, Alexa, Google Home, and SmartThings — meaning you are not locked into any single ecosystem if you later switch phones or voice assistants.
The Linkind Matter Smart Plug (from £10.99, 4.6 stars) is a 15A/1800W-rated outlet that supports Apple Home, Siri, Alexa, Google Home, and SmartThings out of the box. At under £11, it is one of the cheapest routes into a fully cross-compatible smart home setup. A second Linkind variant (£15.99, 4.4 stars) adds built-in timer and schedule functions if you prefer that configuration.
For four plugs in a single purchase, the SONOFF Matter Smart Plug S41s 4-Pack (£29.99, 4.5 stars) brings the per-unit cost to roughly £7.50. All four are ETL certified, support remote and voice control, and include timer scheduling. If you are equipping a living room — TV, floor lamp, speaker, fan — this is an efficient single-box start.
Energy Monitoring: The Plug Feature Worth Paying Extra For
Not all smart plugs track power draw. The ones that do show you exactly how many watts an appliance is consuming in real time and log cumulative usage over days and weeks.
The Kasa Smart Plug Mini KP115 (£12.99, 4.5 stars) adds energy monitoring while staying compact enough not to block the second socket on a double outlet. It works with Alexa and Google Home and requires no separate hub — just your existing 2.4GHz Wi-Fi network.
Use energy monitoring to find your standby culprits
Plug a games console, a TV, or an older router into an energy-monitoring smart plug and check its standby draw. Many devices pull between 5W and 15W continuously when nominally "off". A schedule that cuts power during overnight hours typically recovers the plug's purchase cost within a few months on a standard UK tariff.
The WiZ Smart Plug (£14.19, 4.5 stars) goes further by adding sunset-to-sunrise automation and motion detection integration. If you want a single plug that reacts to ambient light levels — cutting the hall lamp at dawn without a schedule — WiZ handles that without a separate hub or additional sensor.
Motion Sensors: How to Make Your Smart Home Actually React
A timer-based smart plug is convenient. A motion-triggered one is genuinely intelligent. Motion sensors detect movement and fire automations — lights come on as you enter a room, a plug cuts power after an hour of inactivity, or a notification pings your phone if movement is detected while the house is empty.
The TP-Link Tapo Motion Sensor (£13.99, 4.5 stars) uses a Sub-1G low-power wireless protocol rather than standard 2.4GHz Wi-Fi. This matters in UK homes built before 1980, where thick solid brick or stone walls absorb standard Wi-Fi signals aggressively. Sub-1G's lower frequency penetrates wall materials more effectively and extends battery life considerably compared with Wi-Fi-only sensors.
Check hub requirements before buying a motion sensor
The TP-Link Tapo Motion Sensor requires a Tapo Hub to function — it does not pair directly over Wi-Fi. The hub is a separate purchase and can cost as much as the sensor itself. A product listing may not make this dependency obvious until you reach the setup page. Always check for "requires hub" or "requires gateway" in the compatibility section before adding a sensor to your basket.
What to check when comparing motion sensors:
Detection angle: 110–120° covers most rooms; narrower angles suit hallways and corridors.
Battery life: Look for at least 12 months on a single set of batteries to avoid constant maintenance.
Adjustable sensitivity: Essential if you have pets, large houseplants near windows, or a busy street visible through glass.
Hub dependency: Some sensors work via Zigbee, Z-Wave, or direct Wi-Fi. Confirm which before buying.
Smart Bulbs: The Most Visible First Upgrade
Smart bulbs give you the most immediate, visible change to how your home looks and feels. You swap one in exactly as you would replace a failed bulb, and within minutes you have colour temperature control, dimming from an app, and schedule-based automation.
Key specs to confirm before buying:
Lumens, not watts: 800 lumens is the standard replacement for a 60W incandescent. Anything below 650 lumens is only suited to accent or secondary lamps.
Colour temperature range: 2700K is warm white (living rooms, bedrooms). 4000–5000K is neutral to cool white (kitchens, home offices). A wide range gives you flexibility across moods.
Fitting type: UK homes use both E27 (large Edison screw) and B22 (bayonet cap). Photograph your existing bulb before ordering if you are unsure.
Dimming floor: A bulb that dims to 1% is noticeably more versatile than one that only drops to 20%.
Smart bulbs from established brands typically carry a two-year warranty. Cheaper unbranded options often do not — worth checking if bulbs are going into ceiling fittings where replacement requires a step ladder.
A Voice Assistant: The Hub That Ties It Together
Every smart plug, bulb, and sensor benefits from a central voice interface. An Amazon Echo, Google Nest, or Apple HomePod acts as the hub you speak to — and in many setups handles local processing for automations so they fire even if your broadband drops briefly.
Amazon Alexa has the broadest third-party device support at every price point. If you want maximum choice in hardware, Alexa is the safest default.
Google Home integrates tightly with Android phones, Google Calendar, and Nest thermostats. Routines triggered by calendar events are a genuine standout feature.
Apple Home offers the strongest privacy model: processing happens on-device where possible. If you use an iPhone and value local control, Apple Home paired with Matter devices is a coherent, locked-down choice.
Matter-certified devices, including the Linkind and SONOFF plugs above, work across all three ecosystems simultaneously. If you are undecided between platforms, start with Matter devices — you will not be locked in.

How We Chose These Five
We shortlisted products against four fixed criteria:
Rating floor of 4.4 stars from verified purchasers.
Under £30 for individual items, or proportionally strong value in multi-packs.
Ecosystem transparency: devices that clearly state which voice assistants and apps they support, without ambiguity.
No mandatory subscription for basic on/off, scheduling, or energy monitoring functionality.
We excluded devices that required a monthly cloud subscription to deliver features that are standard on competing products at the same price. We also flagged hub dependencies prominently where listings tend to bury them.
Who This Suits — and Who Should Skip It
A good fit if you:
Rent and cannot modify wiring or wall switches
Already own an Alexa, Google Nest, or Apple HomePod device
Want to start with three or four devices and expand at your own pace
Use a mix of Apple and Android devices in the same household — Matter plugs solve the ecosystem split cleanly
Want to reduce unnecessary standby power consumption
Skip plug-in smart home devices if:
You want a whole-home setup from day one. Permanent smart switches wired at the wall are the right route — a professional installer is worth the cost.
Your priority is Thread rather than Wi-Fi. Matter supports both protocols, but not every Matter-certified plug runs over Thread. Check the technical specification tab for the wireless protocol before buying.
You have thick concrete or stone walls across a large property. Hub-based sensors using Sub-1G, like the Tapo system, will outperform standard Wi-Fi devices in these conditions — budget for the hub from the start.
The Order to Buy Them In
If you are equipping a home from nothing, this sequence keeps costs manageable and ensures you are actually using each device before adding the next:
Two smart plugs — one beside the bed, one by the TV. Build the habit of using the app before you add complexity. The Govee Smart Plug 2-pack (£19.99) covers both sockets in a single purchase.
A voice assistant — even an entry-level Echo Dot or Nest Mini transforms the experience from app-only to hands-free, and unlocks most automation features.
Two smart bulbs in the living room or hallway — the most visually rewarding step.
A motion sensor — once you are comfortable creating automations, adding movement triggers makes them genuinely reactive rather than just time-based.
Energy monitoring — either buy a plug with it built in from the start (Kasa KP115) or add it later. This is the feature most likely to recover its own cost in electricity savings.
Buy in this sequence, use each purchase for a fortnight before buying the next, and you will build a setup you actually use — rather than a drawer full of gadgets still in their boxes.
Our picks

Do smart plugs work with both Alexa and Apple Home at the same time?
Matter-certified smart plugs — such as the Linkind Matter Smart Plug and the SONOFF Matter Smart Plug S41s — are designed to work simultaneously with Apple Home, Alexa, Google Home, and SmartThings. You add the device once and it appears across all the apps you use. Non-Matter plugs typically lock you to a single ecosystem, so check the listing carefully before buying.
What is the running cost of leaving a smart plug switched on all day?
A smart plug itself draws very little power — typically under 1W in standby. At UK electricity rates, a single plug costs only pence per year to keep online. The real value is the opposite: a plug with energy monitoring like the Kasa KP115 lets you see how much power the appliance connected to it is drawing, so you can cut standby consumption from devices that waste electricity around the clock.
Do I need a hub to use smart plugs in the UK?
Most smart plugs connect directly over your home's 2.4GHz Wi-Fi network and require no hub. Motion sensors are different — the TP-Link Tapo Motion Sensor, for example, requires a Tapo Hub. Always check the compatibility notes in the product listing before buying a sensor, as hub requirements are not always prominently displayed and the hub is typically a separate cost.
What is the difference between a 15A smart plug and a standard one?
The 15A rating describes the maximum current the plug can safely handle, which corresponds to roughly 1800W at UK mains voltage. This covers the vast majority of household appliances — lamps, TVs, fans, small heaters, and kitchen gadgets. Anything above 2000W, such as a kettle or a tumble dryer, should not be connected to a standard smart plug. Check the wattage of your appliance before plugging it in.
