An outdoor smart plug is one of the most practical smart home additions you can make. Plug in your garden lights, pond pump, or patio heater, and you can schedule them, control them remotely, and — on the right models — track exactly how much electricity they are using. The challenge is choosing a plug that can survive British weather. Unlike indoor plugs, outdoor models must carry a minimum IP44 weatherproof rating, use a robust BS 1363 socket or hard-wired connection, and handle the full 13A (3,120W) allowed by a standard UK circuit.
The market has improved considerably since 2024. Matter support has arrived on outdoor hardware, IP65-rated double-socket units are now widely available, and prices have fallen. Whether you want simple scheduling for Christmas lights or a full Home Assistant automation that turns the garden on at sunset, there is now a well-priced option for every use case.
This guide covers four of the best outdoor smart plugs you can buy in the UK right now, followed by a buying guide covering IP ratings, single versus double sockets, and energy monitoring.
At a Glance: Our Top Picks
- Best overall: TP-Link Tapo P400M — IP65, dual socket, Matter, ~£25
- Best budget double socket: Meross MSS620HK — IP44, dual socket, HomeKit/Alexa/Google, ~£26

TP-Link Tapo P400M — Best Overall
IP rating: IP65 | Sockets: 2 individually controlled | Protocol: Matter (Wi-Fi 2.4 GHz) | Price: ~£25
The Tapo P400M is the most capable outdoor smart plug currently sold in the UK. Its IP65 rating means it is fully dust-tight and protected against water jets from any direction — the highest weatherproofing found on any mainstream consumer outdoor plug. That makes it suitable for completely exposed locations, not just sheltered porches.
It has two independently controlled sockets, so you can schedule your garden lights on one and a pond pump on the other without buying two separate plugs. Matter certification means it works natively with Apple Home, Amazon Alexa, Google Home, and Samsung SmartThings out of the box — and it integrates with Home Assistant via the Matter add-on for fully local control.
Pros: IP65 waterproofing; dual sockets independently controlled; Matter certified; wide 300ft Wi-Fi range claimed by TP-Link; no hub required.
Cons: No built-in energy monitoring on the P400M; 2.4 GHz Wi-Fi only; slightly bulkier than single-socket alternatives.
The P400M is the default recommendation for any UK garden where the socket will be exposed to rain without overhead cover. At around £25 it represents strong value for a dual-socket IP65 Matter-certified unit.
Meross MSS620HK — Best Budget Dual Socket
IP rating: IP44 | Sockets: 2 independently controlled | Protocol: Wi-Fi 2.4 GHz | Price: ~£26
The Meross MSS620HK is a 13A-rated outdoor double socket with a solid weatherproof build and exceptionally broad smart home compatibility. It works natively with Apple HomeKit, Amazon Alexa, Google Home, and Samsung SmartThings — and importantly, it also has a well-maintained Home Assistant integration via the Meross cloud, with a local-polling option for users who prefer to minimise cloud dependency.
The IP44 rating is lower than the Tapo P400M but is sufficient for most UK gardens: it handles rain and garden hose spray, making it suitable for covered porches, against a garden wall under an eave, or in a sheltered patio position. Both sockets can be toggled independently from the Meross app or via voice control, and robust socket covers protect the pins when not in use.
Pros: HomeKit, Alexa, Google, and SmartThings all supported natively; competitive price; solid build quality; 13A per socket; independent socket control.
Cons: IP44 only (not suitable for fully exposed positions); no Matter support at time of writing; energy monitoring not included on this model.
If you are already invested in the Apple ecosystem and want HomeKit support without spending extra, the Meross MSS620HK is the most straightforward outdoor option at this price point. It is available on Amazon UK and from the Meross website.
TP-Link Tapo P410M — Best Value Single Socket
IP rating: IP54 | Sockets: 1 | Protocol: Matter (Wi-Fi 2.4 GHz) | Price: ~£20
Where the P400M is the flagship dual-socket unit, the P410M is TP-Link's compact single-socket outdoor plug aimed at buyers who only need one output. Its IP54 rating (dust-protected, splash-resistant) sits between IP44 and IP65 and is appropriate for covered outdoor locations and most British gardens. The operating temperature range of -20°C to +50°C means it will cope with winter frosts without issue.
The P410M's standout feature at this price is built-in energy monitoring: it tracks real-time wattage and historical kWh consumption, which is useful for monitoring a pond pump or outdoor electric heater. Like the P400M, it is Matter-certified, so it slots straight into Apple Home, Alexa, Google Home, and Home Assistant via Matter with no additional configuration. TP-Link also notes zero-crossing detection and overload protection as built-in safety features.
Pros: Energy monitoring included; Matter certified; compact single-socket form factor; IP54 weatherproofing; frost-rated to -20°C; child safety lock.
Cons: Single socket only; IP54 is not suitable for fully exposed locations; primarily a European launch with UK availability from specialist smart home retailers and Amazon UK.
The P410M is the plug to buy if you only need one outdoor outlet and want to keep an eye on consumption — for example, monitoring an outdoor fridge or a pump running a water feature.

IKEA TOFSMYGGA — Best for Smart Home Enthusiasts
IP rating: IP44 (lid closed) | Sockets: 2 independently controlled | Protocol: Matter over Thread | Price: ~£13
IKEA launched the TOFSMYGGA in early 2026 as its first outdoor smart plug — and priced it aggressively at around £13 in the UK. The TOFSMYGGA uses Matter over Thread, the newer mesh radio protocol that offers lower latency and better reliability than Wi-Fi for smart home devices. To use Thread, you will need a Thread border router, such as an Apple HomePod mini, Apple TV 4K, or IKEA's own DIRIGERA hub.
Once paired, the TOFSMYGGA integrates directly into Apple Home, Google Home, or Amazon Alexa via Matter — and also works with Home Assistant's Matter add-on for fully local control. It has built-in energy monitoring and can control up to two sockets independently. IKEA also supports pairing multiple units with a single IKEA remote or motion sensor, useful if you want to trigger garden lights with movement detection.
Pros: Exceptionally low price for a dual-socket Matter-over-Thread device; energy monitoring included; Apple Home, Google, Alexa, and Home Assistant compatible; IKEA ecosystem integration (remotes, motion sensors).
Cons: Requires a Thread border router for Thread networking (falls back to Bluetooth pairing without one); IP44 only — not for fully exposed locations; pairing required a few attempts for some users at launch; relatively new product with a shorter track record than established brands.
The TOFSMYGGA is the best option if you already have an Apple TV 4K or HomePod mini acting as a Thread border router, and you want to minimise Wi-Fi congestion in a garden with multiple smart devices. It is available in UK IKEA stores and online.
Outdoor Smart Plug Buying Guide
IP44 vs IP65: Which Do You Need?
The IP (Ingress Protection) rating is the single most important specification for any outdoor electrical device. The rating comprises two digits: the first indicates solid-particle protection, the second indicates liquid protection.
- IP44: Protected against solid objects larger than 1 mm, and against water splashing from any direction. Suitable for covered porches, garden walls under an eave, or sheltered patio positions. IP44 handles typical British rainfall and a garden hose used nearby, but not a direct water jet aimed at the socket.
- IP54: Dust-protected (not fully sealed) and splash-resistant. A practical mid-point rating that suits most sheltered garden installations.
- IP65: Fully dust-tight and protected against water jets from any direction. Suitable for completely exposed positions — a post in an open lawn, near a pond, or anywhere without overhead cover. Choose IP65 if there is any doubt about the level of exposure.
For most UK homes with a back garden and a standard socket position under a porch or wall light, IP44 is sufficient. For a standalone post, poolside installation, or a coastal garden, IP65 is the safer choice.
Single vs Double Socket
Double-socket outdoor plugs (such as the Tapo P400M, Meross MSS620HK, and IKEA TOFSMYGGA) offer independent control of two circuits from a single physical unit. This is typically better value and tidier than buying two separate single-socket plugs, since you only need one outdoor circuit to run two independently scheduled devices. The only reason to choose a single socket is if you genuinely need just one output and want the most compact form factor possible.
Energy Monitoring
Not all outdoor smart plugs include energy monitoring. The Tapo P410M and IKEA TOFSMYGGA both include it at a budget price; the Tapo P400M and Meross MSS620HK do not. Energy monitoring is particularly useful outdoors for devices that run continuously — pond pumps, outdoor fridges, and electric garden heaters — where you want to quantify the running cost and optimise scheduling. If this matters to you, check the specification before buying.
Matter and Home Assistant Support
Matter-certified plugs (P400M, P410M, TOFSMYGGA) integrate with Home Assistant's built-in Matter integration without any third-party add-ons or cloud dependencies. This means automations continue to function even if the manufacturer's servers go down. Non-Matter plugs such as the Meross MSS620HK can still be used in Home Assistant via the Meross integration, though this uses the Meross cloud.
If Home Assistant local control is a priority, our guide to best smart plugs UK covers the broader indoor landscape, including Shelly and Zigbee options with fully local APIs. For outdoor use specifically, the Tapo P400M or P410M via Matter are the most straightforward path to reliable local control in Home Assistant.
UK Socket Compatibility
All outdoor smart plugs reviewed here use the standard UK BS 1363 three-pin plug format and are rated for the UK 230V / 50Hz mains supply. None require a separate hub or transformer. Simply plug into an outdoor-rated socket — which itself must be installed by a qualified electrician in compliance with BS 7671 (the IET Wiring Regulations) — and set up via the manufacturer's app or a Matter controller.
Our Recommendation
For most UK gardens, the TP-Link Tapo P400M is the safest all-round choice: IP65 weatherproofing, dual independent sockets, Matter certification, and a price of around £25 deliver the best combination of durability and future-proof compatibility. If your budget is tight and you are happy with IP44, the IKEA TOFSMYGGA at around £13 is remarkable value for a dual-socket Matter-over-Thread device with energy monitoring — particularly if you already own a Thread border router.
Always buy outdoor smart plugs from a reputable UK retailer to ensure you receive the correct BS 1363 plug version with valid UKCA certification for the Great Britain market.
