Thanks to Matter support in iOS and iPadOS, you can now add compact UK energy-monitoring plugs like the TP-Link Tapo P110M directly to the Apple Home app by scanning the QR code on the casing. Here are the top-performing HomeKit sockets from our best smart plugs UK test bench.
At-a-Glance UK Specification & Price Comparison
All models below feature a native UK Type G three-pin plug or socket conforming to BS 1363 (230V–240V AC, 50Hz) and have been evaluated for British double wallplate clearance, standby wattage, and local network reliability:
| Model (UK BS 1363) | Connection to Apple Home | Home Hub Needed for Away Access | UK Price & Link |
|---|---|---|---|
| TP-Link Tapo P110M | Matter over 2.4 GHz Wi-Fi | HomePod / HomePod Mini / Apple TV 4K | £11.99 (Amazon UK) |
| Eve Energy (UK) | Matter over Thread | HomePod Mini or Apple TV 4K (Thread) | £37.99 (Amazon UK) |
| Meross MSS315 (UK) | Matter over 2.4 GHz Wi-Fi | HomePod / HomePod Mini / Apple TV 4K | £19.99 (Amazon UK) |
| TP-Link Tapo P304M | 4 Outlets via Matter Wi-Fi | HomePod / HomePod Mini / Apple TV 4K | £36.99 (Amazon UK) |
1. Why Tapo P110M Changed the Game for UK Apple Home Users
At £11.99 single (or ~£9.75 per socket in a 4-pack), the Tapo P110M pairs straight into Apple Home via its Matter QR code while still giving you full UK pence-per-kWh energy tracking inside the companion Tapo app. For purists who want zero Wi-Fi traffic and zero cloud accounts, the Thread-based Eve Energy UK remains the gold standard.
How We Test (UK BS 1363 Workbench Protocol)
Our evaluation protocol is specifically designed around British domestic electrical standards rather than generic international spec sheets:
- Twin Wall Socket Clearance (BS 1363-2): We fit each plug into a standard UK MK Logic Plus and BG Nexus double switched wall socket to verify that a casing width of 52–57 mm leaves the adjacent socket and individual rocker switches completely unobstructed.
- True-RMS Standby & Relay Wattage: Using a calibrated 230V/50Hz inline wattmeter (0.1W resolution), we log 24-hour parasitic power consumption both with the relay open (Wi-Fi/Thread listening) and with the relay closed (energised coil + status LED).
- Thermal Pin & Load Verification: While a BS 1363 fuse is rated to 13A (2,990W at 230V), we monitor brass pin temperature after 60 minutes under sustained 2,200W resistive load and verify over-current auto-shutoff behaviour in the companion firmware.
- UK ISP Router & Offline Timer Resilience: We test 2.4 GHz onboarding on merged SSIDs (BT Smart Hub 2, Sky Max Hub, Virgin Media Hub 5) and disconnect the WAN fibre cable to confirm whether scheduled timers and local Matter/Thread automations still execute on time.
Added four Tapo P110M plugs to Apple Home via my HomePod Mini in about three minutes flat. Siri response is instant.
Awesome to hear James! Local Matter execution over LAN makes Siri toggling practically instantaneous.
