These are the best smart plugs for 2019.

How to buy the best smart plug for you

Smart plugs are typically operated over Wi-Fi (or occasionally Bluetooth) from your phone – you can turn that corner light on and off with a tap, or even set it on a schedule. Every smart plug has the same basic functionality.

Some products let you take the idea a little further with zones (groups of plugs) and scenes (automated settings on a schedule or based on your movements). Happily, most of the best smart plugs work with the popular smart home platforms, like Apple HomeKit and Samsung SmartThings.

That's really your first consideration – whether a smart plug works with the kit you've already got installed (or want to get installed). Then you can look at extra features, like turning sockets on or off when you leave the house. Without any further ado, these are the best smart plugs for the UK in 2019.

Our pick of the best smart plugs you can buy in 2019

Belkin WeMo Insight Switch best smart plugs 2019

1. Belkin WeMo Insight Switch

A smart plug for smart people

No. of sockets: 1
Indoor/Outdoor Use: Indoor only
Connectivity: 802.11n W-Fi (2.4GHz)
Compatible with: Android 4.4 or later; iOS 9 or higher
Reasons to buy
+Wi-Fi and 3G/4G ready+Works with Amazon Alexa and Nest+Easy to set up and use+Part of modular WeMo system

This is Belkin's top-of-the-line smart plug and you'll struggle to find anything better – it works with Amazon Alexa, Apple HomeKit and Google Home, it can slot right into most smart home setups, and it can monitor your energy usage as well as letting you turn your appliances on and off from your phone.

Scheduling on and off times is simple – to make sure the kids turn the TV off when they're told to, for example – or you can just use it manually. It's fast, it's reliable, and as we've said it connects to a lot of different third-party apps and services, including the always useful automator tool IFTTT (If This Then That).

You might think it would be relatively easy to design a smart plug app, but you'd be surprised at the mess some manufacturers make of it. Thankfully the WeMo app is clear and straightforward on both Android and iOS, and we'd actually recommend other WeMo kit as well if you're thinking about extending your smart home. Hands down one of the best smart plugs around.

2. Hive Active Plug

A great way to extend your Hive system

No. of sockets: 1
Indoor/Outdoor Use: Indoor only
Connectivity: 802.11n Wi-Fi (2.4GHz)
Compatible with: Android 4.4 or later; iOS 9 or later
Reasons to buy
+Part of Hive Smart Home System+Easy to set up and use

Designed to work in conjunction with the Hive Hub developed by British Gas (though you don't have to be a British Gas customer to use it), the Hive Active Plug works in a similar way to the Belkin WeMo Insight Switch above – you can turn your sockets on and off with a tap on your phone or on a preset schedule.

In other words, very handy for those times when you need to check whether you left the iron on, or just fancy boiling the kettle for a cup of tea while you’re still lying in bed upstairs. The only real catch is that Hive Hub requirement: the Hive Active Plug won't work without one, so this is only really the best smart plug for a specific subset of people.

Naturally the Hive Active Plug is controlled using the free accompanying Hive apps for iOS and Android, and as well as a schedule you can also create actions that work in conjunction with each other (so switching on a lamp when a door sensor is triggered, for example). If you already have Hive kit installed, it's ideal. You can control the plug with the Amazon Alexa assistant too.

TCP Smart Wi-Fi Plug best smart plugs 2019

3. TCP Smart Wi-Fi Plug

The smart plug basics with a few useful extras

No. of sockets: 1
Indoor/Outdoor Use: Indoor only
Connectivity: Wi-Fi (2.4GHz)
Compatible with: Android 4.1 or later; iOS 8 or later
Reasons to buy
+Works with Alexa and Google Assistant+Simple setup and operation

The TCP Smart Wi-Fi Plug doesn't stand out in any particular area, but it does come with some very handy extras – like Alexa and Google Assistant integration – and it works very reliably, so it's an easy call for one of the best smart plugs around.

You don't really want to get lost in a maze of settings and menus when it comes to setting up or operating your smart plug, and thankfully this one is very easy to get up and running. Plug it into a spare socket, set up the Android or iOS app, and that's just about job done.

The plug can be turned on and off using the app, you can set it to go on and off on a schedule, and you can even do a countdown timer (if you want the lamp to turn on in 30 minutes, for example).

D-Link DSP-W118 Mini Wi-Fi best smart plugs

The Mini Wi-Fi Smart Plug from D-Link offers a neat, compact size, as well as all the functionality you need.

4. D-Link DSP‑W118 Mini Wi-Fi Smart Plug

A simple and reliable smart plug from D-Link

No. of sockets: 1
Indoor/Outdoor Use: Indoor only
Connectivity: 802.11n/802.11g Wi-Fi
Compatible with: Android 4.4 or later; iOS 9 or later
Reasons to buy
+One of the most compact smart plugs+Works with Alexa and Google Assistant

All you really need from a smart plug is to have it work reliably from your phone, whether you're turning it on and off manually or setting it on a schedule, and the D-Link DSP-W118 delivers here. It's not the first smart plug that D-Link has put out, and that expertise means it knows exactly how to put together a smart plug like this.

It's worth mentioning the size of this particular D-Link smart plug, because it's smaller than most at 8.4 cm x 6 cm x 6 cm: that means you can squeeze two of these side by side on a double plug socket, something that stops a lot of smart appliances like this from being as useful as they can be.

On top of that you've got polished apps for Android and iOS to make use of, and there's integration with Google Assistant, Amazon Alexa, and the always-useful IFTTT (If This Then That) as well. If you're after one of the best smart plugs around, then make sure you check out the D-Link DSP-W118 smart plug.

Teckin Smart Plug Wi-Fi best smart plugs 2019

5. Teckin Smart Plug Wi-Fi

Cheap but very competent

Reasons to buy
+Simple to set up and use+Comes with Alexa/Google Assistant support

Teckin is perhaps not the best-known tech brand out there, but its smart plugs are inexpensive, simple to use, and compatible with Amazon Alexa and Google Assistant too – so you can turn on all kinds of gadgets with the power of your voice.

We also like the design of the Teckin Smart Plug Wi-Fi, which is discreet and unobtrusive. The power supply can be set to work on a timer if you need it to, or operated manually through the app.

The plugs also include a sliding safety cover to stop kids from poking their fingers in where they shouldn't be. It doesn't have all the bells and whistles of some of its rivals but it's still one of the best smart plugs of 2019.

Eve Energy best smart plugs

6. Eve Energy

Ideal for Apple HomeKit – and not much else

No. of sockets: 1
Indoor/Outdoor Use: Indoor only
Connectivity: Bluetooth 4.0 Smart
Compatible with: iOS 10+, tvOS 10+
Reasons to buy
+Easy to set up and use+Part of Eve Systems' smart home range+Works with Apple HomeKit

There's a lot to like about the Eve Energy smart plug, but there's also a big caveat, which is that it only works with Apple gear. You're going to need an iPhone (or iPad) to operate this, and it's going to work best as part of a HomeKit setup. Sorry, Android users.

In fact, Eve Systems (formerly Elgato) used to specialise in TV tuner and video capture products for Apple devices before switching its focus towards smart home tech instead. Even if it is Apple-centric, this is a very powerful plug: you can create geofences, triggers, actions and scenes using the free accompanying Eve app or Apple Home.

Unusually the Eve Energy relies on Bluetooth 4.0 Smart rather than a Wi-Fi connection, which means you're going to need a 4th-generation Apple TV or newer, or an Apple HomePod smart speaker as an intermediary if you want to switch connected devices on and off away from home. Otherwise, you can control the plug directly from the app.

TP-Link HS110 best smart plugs

7. TP-Link HS110

Amazon Echo-ready smart plug

No. of sockets: 1
Indoor/Outdoor Use: Indoor only
Connectivity: 802.11b/g/n Wi-Fi (2.4GHz)
Compatible with: Android 4.1 or higher; iOS 8 or higher
Reasons to buy
+Elegant, minimalist design+Works with Amazon Echo (sold separately)+Easy to use via the Kasa app

This smart plug from networking specialists TP-Link has everything you need to remotely control connected devices whether you’re at home or away. The driving force for the product is the free Kasa app for iOS and Android devices, which connects to the TP-Link HS110 via your wireless router. It can also be controlled with your voice, provided you have an Amazon Echo.

The Kasa app is easy to use and enables you to switch the smart plug on or off, create custom actions and set a schedule that can trigger connected devices to switch on and off automatically throughout the day. Everything works smoothly and as advertised, and you can use it on its own or in combination with other TP-Link gear.

A step up from the TP-Link HS100 smart plug, this one includes energy monitoring, so you can see how long a connected device has been active for – and how much it’s costing you when it's switched on. It lacks support for Apple HomeKit and Samsung SmartThings, but this is otherwise a very capable plug.

Amazon Smart Plug best smart plugs 2019

Amazon Smart Plug

8. Amazon Smart Plug

The best smart plug for covering the basics

No. of sockets: 1
Indoor/Outdoor Use: Indoor only
Connectivity: 802.11b/g/n Wi-Fi (2.4GHz)
Compatible with: Android or iOS (iOS 10 or higher)
Reasons to buy
+Perfect for your Alexa-powered home+Nice and cheap

If you don't want to spend much and already have an Amazon Echo or two set up in your home, then the Amazon Smart Plug covers the basics for not much money at all. It's simple to set up and use, and can be controlled with your voice.

That said, it only works through the Alexa app on your phone, so it's really only the best smart plug if you rely on Amazon kit – it doesn't have quite as many features and functions as you'll find on the other smart plugs in this list.

If you're all set up with Amazon gear though, it might just be the best smart plug in 2019 for you. Coming from Amazon, you know it's not going to let you down.

Ikea Trådfri smart plug best smart plug 2019

9. Ikea Trådfri smart plug

A bargain basement option from Ikea

Reasons to buy
+Won't dent your bank account much+Works with HomeKit as well

Ikea is making quite a name for itself with its Trådfri range, and this is the smart plug bit of it. These smart home gadgets stick to the basics, but they do them well, and for a very cheap price as well.

The Ikea Trådfri smart plug does exactly what you would expect it to, and can be controlled via an app to operate manually or on a schedule. If you connect the plug up to a Trådfri gateway you need a steering device to go with it (most Trådfri devices come with one).

Ikea recently added HomeKit support so this plug will play nicely with other gear hooked up to your Apple network. It's also an alternative way of controlling the device if you don't want to use Ikea's own app.
