Dual-protocol done properly — pair it hubless over Matter/Thread if you just want a switch, or feed it into an Aqara hub over Zigbee if you actually want the energy stats, because (this is the catch) Aqara plugs don't put power or energy readings on the Matter side at all, only the on/off state. The RGB ring reading out live power draw is a genuinely nice touch in the Aqara app, but treat the HA side as switch-only until that changes. It's also brand new stock (announced 23 July 2026), so don't expect flawless Thread commissioning on day one.

The premium pick: officially Works with Home Assistant certified (Eve joined the programme in April 2025), connecting via Matter-over-Thread with energy monitoring, 100% local control and no cloud account at all. At £39.95 it's roughly seven times IKEA's GRILLPLATS (£6, also Matter-over-Thread) and three times SONOFF's Zigbee S60ZBTPG or TP-Link's Tapo P110 — you're paying for the WWHA certification and Eve's own energy cluster, built with HA's developers, avoiding the stuck-at-zero cumulative-energy bug on cheaper Matter plugs. It's compact (72 x 72 x 71mm) though Eve doesn't publish a standby-power figure. You'll need a Thread border router (ZBT-1/SkyConnect, Apple TV or HomePod); each plug also strengthens the mesh.

IKEA's 2026 replacement for the Tretakt and Inspelning, and at £7 with full energy monitoring (power, voltage and amps) it still undercuts SONOFF's S60ZBTPG (£13.99) and TP-Link's Tapo P110 (£12.99) by roughly half. The trade-off is protocol lock-in: it's Matter-over-Thread only, so you need a Thread border router — a Home Assistant Connect ZBT-1, Apple TV or DIRIGERA — already running before it does anything, unlike the Zigbee S60ZBTPG or standalone Wi-Fi P110. IKEA doesn't publish a standby draw figure, so treat idle-power claims with caution until someone measures a unit. Best value pick if you already have Thread infrastructure; otherwise the P110 is the easier standalone buy.

The cheapest name-brand smart plug you can buy in the UK — around £8 and rock-solid on the local tplink integration. No energy monitoring, so spend the extra couple of pounds on a Tapo P110 if you want power stats. At just 51×72×40mm it's genuinely compact, sitting close to the wall so it won't block the second socket on a UK double gang — a real problem with bulkier smart plugs. The 13A/2990W rating covers kettles and heaters if you need switched high-draw sockets. It's rated for indoor use only, 0-35°C, with a sliding safety cover over the socket — no IP rating for anything damp like a shed or greenhouse.

This is the plain P110 with Matter certification added, and at £9.97 it's still essentially the same single-unit price as the non-Matter version (£9.99) — Matter comes free here rather than at a premium, unlike most TP-Link Matter upgrades. The catch is which pairing path you use: connect it over Matter and HA only sees three entities (Energy, Energy Exported, Power), losing the voltage, current and frequency detail the native tplink integration exposes in full. Buy this one specifically if you're running Apple Home, SmartThings or another ecosystem alongside HA and need one plug all of them can control — otherwise the plain P110 does the identical job with richer HA sensors for the same money.

The default UK smart plug: cheap, everywhere, and HA's core tplink integration polls it locally with per-plug energy stats that are accurate enough for tumble-dryer automations. Buy multipacks — Tapo's own store runs the 2-pack for well under £8/unit and the 4-pack cheaper still, beating a single Amazon unit outright. Prefer Zigbee mesh or don't want another Wi-Fi device on the router? The SONOFF S60ZBTPG matches it on price and load rating without eating Wi-Fi bandwidth. Need to monitor a whole extension lead instead of one socket, look at the Tapo P304M power strip. For a single always-on appliance on Wi-Fi, the P110 is still the easiest, cheapest option.

A small UK reseller's plug that ships pre-flashed with ESPHome (or Tasmota), so it lands in HA with zero cloud dependency, zero vendor app, and OTA firmware you control end to end — nothing bricks if the seller vanishes tomorrow. That's the tinkerer's dream at under £15: no subscription, no forced updates, full local ownership. The tradeoff is a small, largely unknown brand rather than an established name — LocalBytes itself admits its factory power calibration "is not perfect," so budget time to calibrate against a known load. Best suited to privacy-conscious, offline-first households already running HA who don't mind setup friction in exchange for never phoning home.

A tiny 16A power meter that hides behind a socket, in a ceiling rose, or spliced into a consumer unit to monitor a whole circuit, not just one device. Unlike a plug-in energy monitor, which only sees whatever is plugged into it, this wires inline on the live conductor, so it can sit on a cooker circuit, an immersion heater, or a lighting ring and total everything downstream. It is not a CT-clamp meter — no clip-on sensor, just two screw terminals — so the circuit needs isolating to fit it. No relay, just measurement, fully local on the core Shelly integration and cheap enough to scatter around the house.

The power-user's Wi-Fi plug: HA's excellent core shelly integration talks to it locally and push-updates instantly, with proper 13A/3000W rating and precise power metering. At roughly double a Tapo P110 or SONOFF S60ZBTPG, it earns its keep — a local RPC API keeps automations running if the internet drops, and on-device scripting can enforce power limits without HA in the loop. Standby draw is under 1W, so running it 24/7 costs pennies a year. At 60 x 60 x 56mm it's a chunkier cube than the P110, so check it won't block a neighbouring socket. (The smaller Plug S Gen3 is EU-pin only — this is the BS1363 model.)

At roughly thirty pounds it undercuts four separate Tapo P110 mini plugs, which cost more combined for the same four-socket count, while using one wall socket instead of four — the better buy for a media unit, desk setup or entertainment cluster where devices sit side by side rather than scattered. It is a proper UK extension lead: 260mm long with a 1.5m cable, BS1363 sockets with child-safe shutters, each switched independently with its own status LED. One catch a few retailer listings get wrong: there are no USB ports on this model, confirmed by TP-Link's own spec sheet and independent reviews — AC sockets only.

The best Z-Wave smart plug with genuine UK BS1363 pins — accurate energy monitoring, S2 security and a colour LED ring that shows load at a glance. At £42-55 depending on retailer it costs more than the Zigbee energy plugs we cover elsewhere, and the premium only pays off if you're already on Z-Wave: every Wall Plug repeats the mesh, extending range to door locks and battery sensors further from the hub. It's also a chunky ~56mm cube that can overhang and block a neighbouring socket on a double gang outlet — check clearance first. S2 security is the right call here, since unlike a battery sensor this thing is mains-connected and always on.

The step beyond plug-level monitoring: a CT-clamp meter that sits in your consumer unit and feeds two circuits' worth of power into HA's Energy dashboard via the core Shelly integration — all local, no subscription. Compare that to the Hildebrand Glow: Glow reads your actual smart meter register for one whole-home import/export figure, while the EM Gen3 clamps onto specific cables you choose — grid tails, a solar inverter, an EV charger — so it's more flexible but per-circuit rather than automatically whole-home. Shelly quotes ±2% current accuracy rather than a formal IEC class. Needs an electrician unless you're confident around the consumer unit.

This is a genuine in-wall replacement, not a plug-in gadget — isolating the circuit and wiring in the faceplate is a 15-minute job if you're competent with a screwdriver, but get an electrician if you're not; a like-for-like swap isn't notifiable under Part P, but live mains isn't something to guess at. At roughly £68-70 it costs more than a cheap plug-in energy monitor plus a separate USB charger, but you get both in one flush faceplate with no trailing plug. Best suited to a TV/media unit or kitchen worktop, where a bulky adaptor looks wrong — check your back-box depth first, since anything under 25mm needs the included spacer.

Best-value Zigbee energy-monitoring plug for UK sockets: pairs straight into Zigbee2MQTT or ZHA (no eWeLink hub needed), reports power/energy, and doubles as a solid Zigbee router. The Type G version of the well-reviewed S60 series. Usually a couple of pounds cheaper than TP-Link's Tapo P110, and for a Zigbee mesh already anchored by a Home Assistant dongle it's the better buy — no cloud dependency, no separate WiFi credentials, and one more repeater strengthening the network. If you don't already run Zigbee, the Tapo's plug-and-play WiFi setup and app are simpler. Best fit: monitoring always-on appliances (fridges, routers, AV kit) where local, hub-free readings matter more than a slick app.

A tidy, well-built Zigbee plug that pairs into a Philips Hue bridge as well as Zigbee2MQTT/ZHA — a real point of difference from the SONOFF S60ZBTPG and Aqara Power Plug H2 UK RGB on this list, neither of which offer that Hue-bridge route into HA. At £19.99 it sits between the SONOFF (£13.99, cheapest energy-monitoring Zigbee plug here, but hub-free Z2M/ZHA only, no Hue) and the pricier Aqara H2 UK RGB (£32.99, Matter/Thread native but no power or energy data over Matter at all). Best fit: a household already running a Hue bridge for lighting that wants one more plug reporting proper wattage into HA without adding a second ecosystem. If you're not on Hue, the cheaper SONOFF is the better buy.

A heating-trade staple you'll find in every UK plumber's merchant rather than an electronics retailer — Salus sells to installers first, smart-home shoppers second, so don't expect flash sales or Amazon Prime delivery. At £32 it's pricier than SONOFF's iPlug (£14) or Innr's SP 244 (£17), both of which expose usable energy monitoring in Home Assistant; you're paying Salus prices for a plug you're buying specifically because it skips metering. Buy it for what it does well: a plain, reliable 13A BS1363 switch and Zigbee router that pairs straight into Zigbee2MQTT or ZHA with no Salus gateway required.

This is a 20A in-line wired switch, not a plug — it's wired directly into the circuit it monitors, typically an immersion heater or another hardwired appliance. That's mains-wiring work, realistically electrician territory for anything permanent, unlike a £15 plug-in energy monitor you just plug in and forget. The trade-off buys you whole-circuit monitoring a plug-in device can't offer, plus an on-device LCD for at-a-glance power, voltage and current without opening Home Assistant. Works locally via the SonoffLAN HACS integration, and the ESP32 inside is ESPHome-flashable if you want eWeLink out of the picture entirely.

This 2-pack lands around £11 a plug — cheaper than a single Tapo P110 (£12.99), but pricier than Tapo's own multipacks, which dip under £8/unit. The catch is HA support isn't native: it's the community meross_lan integration via HACS, so functionality depends on one volunteer maintainer rather than a vetted core integration — fine for tinkerers, a dealbreaker if you want zero-touch setup. Once installed it runs fully locally over HTTP/MQTT with no cloud round-trip. Best fit is multi-socket energy-monitoring rollouts (workshop, home office, several appliances) where the per-plug price undercuts buying singles — not a first smart plug for HA beginners.

The go-to UK outdoor smart plug — IP44-rated with two independently switchable 13A BS1363 sockets. At around £34 it sits mid-market: pricier than no-name IP44 plugs from marketplace sellers, but cheaper than premium HomeKit-certified outdoor sockets. It's a corded unit rather than a wall-mounted pass-through — the roughly 28cm cable is short, so plan to site it near an existing outdoor socket or extension lead rather than at the far end of the garden. Best suited to festoon lights, a pond pump, or Christmas lights on a patio or deck. Setup needs the Meross cloud app for initial pairing before meross_lan takes over for fully local HACS control — no energy monitoring on this model.

The CAD (Consumer Access Device) is the bit that actually matters for Home Assistant — a small unit that pairs with your existing SMETS1/2 smart meter over Zigbee and pushes readings to a local MQTT broker or the Glow cloud API. The 3.5-inch touchscreen display bundled with it is really for people who want an in-home dashboard; if you only care about HA data, Hildebrand has previously sold CAD-only versions without the display for less, though stock availability varies. Either way you need a smart meter already installed and enrolled with the DCC before ordering — verify via the Bright app first.

Britain's favourite solar-diverting EV charger, and its energy data slots straight into Home Assistant's energy dashboard via the myenergi HACS integration — though it's cloud-only, so automations depend on their servers rather than local control. Stick with the 7kW single-phase model unless you have a rare UK three-phase supply; the 22kW variant can't charge any faster without it. Tethered and untethered cost roughly the same, so pick tethered for convenience. Budget £400-700 on top of the unit price for professional installation. If you own your home with a driveway you won't qualify for an OZEV grant — that's reserved for renters and flat owners now.
