The best smart plug and switch enables you to switch whatever appliance is connected to it on or off without having to leave the sofa. A smart plug extends the scope of your smart home, enabling you to remotely control everything from lamps to fans, even when you’re not close by. 

The best smart plugs are extremely easy to install - just connect one to an existing power outlet, however, the best smart switches are more fiddly and if you’re not qualified for home electrics, will require professional installation. Whichever of the two options you plump for, they’re both compact and won’t look out of place in your home. 

As well as making life easier, the best smart plug or switch can also help when it comes to saving energy, and money. If you’re forgetful and regularly leave the house with the lights or the coffee maker still on, you’ll no longer have to wait until you get home to switch them off (or make yourself late by going back), as you can use your smartphone instead. 

Many smart plugs build on this with the ability to track how much energy is being used by the appliance connected to the smart socket. Our article, do smart plugs save energy, offers a more in-depth look at the energy monitoring feature. 

Just like other smart home devices, as well as using your smartphone to control smart plug and switches, you can also use your voice, providing you have one of the best smart speakers or smart displays in your home. They can also be set to work in tandem with other smart home gadgets, so with just one command you can dim your smart lights, turn the smart thermostat up a few degrees, and switch on appliances connected to smart plugs and switches. 

There’s a wide array of smart plugs and switches on the market, from tech stalwarts such as Amazon and Hive to smaller brands including TP-Link, WeMo, and Eve. We’ve put a number of models to the test to help you decide which is the best smart plug and switch for you.

The best smart plug you can buy

Specifications

Dimensions: 2.8 x 1.5 x 2.4 inches (US) / 7.2 x 7.2 x 7.1 cm (UK)
Wireless connection type: Bluetooth and Thread

Reasons to buy

+
Excellent energy monitoring
+
Apple HomeKit compatible
+
Thread support

Reasons to avoid

-
No Alexa or Google Assistant support
-
Expensive compared to the rest of the market

The Eve Energy smart plug is the best you can buy in our eyes, although it has one small flaw - while it’s HomeKit-enabled, it won’t work with Alexa or Google Assistant. Simple to use, it keeps track of the energy consumption of the devices plugged into it - and if you provide specific details from the energy provider - the total cost, too. 

The smart plug connects over Bluetooth, or Thread smart home technology  - if you have a HomePod Mini or an Apple TV in your home - so you’ll be able to control even when you’re not at home. Thread is more stable than Wi-Fi and puts an end to smart home devices failing to respond.  

However, compared to the rest of the market it's expensive and its all-white design is simplistic, but don't let that fool you - it’s got plenty of handy features such as the ability to create schedules.

The best smart plug powerstrip

Specifications

Dimensions: 10.2 x 2.5 x 1.5 inches / 26 x 6.34 x 3.8cm
Wireless connection: Wi-Fi

Reasons to buy

+
Simple to use
+
Three smart sockets
+
Compatible with Alexa and Google Assistant

Reasons to avoid

-
No HomeKit support
-
No energy monitoring

For Alexa and Google Assistant-based smart homes, this smart powerstrip is a worthy choice if you need several smart plugs in one location. While it lacks energy monitoring and HomeKit support, it’s easy to use and even has a handy Away mode that will turn the plug on and off at random time - ideal if a radio or lamp is connected to one of the outlets and you want to to help deter unwanted intruders. There are also two USB ports on the powerstrip - although these aren’t smart. 

Like all of the smart plugs in this line-up - the plain all-white design won’t win any prizes for style but it offers almost all of the functions we’d expect, such as being able to set schedules and even create automations where other TP-Link branded products work in tandem alongside the smart plug.

The best smart plug for all voice assistants

Wireless connection: Wi-Fi

Reasons to buy

Reasons to avoid

Integration with voice assistants differs per territory

If you’ve using different voice assistants in your home, or you haven’t settled on your final option, the WeMo WiFi smart plug is ideal - as in the US at least it works with Alexa, Google Assistant and HomeKit. Unfortunately, in the UK, it’s HomeKit only, we’re afraid.  

A compact smart plug, that’s simple to use and has most of the features you’d expect, including the ability to set schedules so it turns on or off automatically, as well as engage the Away mode – which randomizes the times at which the smart plug switches on and off – to simulate occupancy. It’s affordable and has a manual power buttons, and LED that illuminates when the plug is switched on.

It’s only lacking when it comes to energy monitoring features, which is why it's a cheaper alternative to Eve Energy, but those on a budget we think this is a compromise worth making.

The best smart plug for Alexa

Specifications

Dimensions: 3.2 x 1.5 x 2.2 inches (US) / UK 5.6 x 9.62 x 6.3 cm (UK)
Wireless connection: Wi-Fi

Reasons to buy

+
Simple setup
+
Compatible with Alexa
+
Easy to create automations with other smart home devices

Reasons to avoid

-
No HomeKit or Google Assistant support
-
No energy monitoring

If your home is all-things Alexa, then opting for the Amazon-branded smart plug makes perfect sense. It may not be the cheapest smart plug on the market, but it integrates well with Alexa routines - making setting up automations for your home a simple task. 

The relatively bulky smart plug connects to the internet over Wi-Fi, so it can still be controlled even when you’re not at home and was extremely simple to set-up thanks to a QR code that did the hard work for us. 

On test, it proved to be responsive both when controlled by the app or Alexa. There’s no energy monitoring function, neither is there an Away mode to help deter intruders by randomly turning devices on or off. Unsurprisingly, you're out of luck with this smart plug if you want Google Assistant or HomeKit support too, but it’s still a solid smart home device.

The best smart plug for lights

Specifications

Dimensions: 2 x 3 x 1 inches (US) / 6.4 x 6 x 6cm (UK)
Wireless connection: Bluetooth

Reasons to buy

+
Compact design
+
Integrates with Philips Hue system
+
Works with Alexa, Google Assistant, and HomeKit

Reasons to avoid

-
Expensive compared to rest of the market
-
Requires Hue Bridge for control when you're not close by
-
No energy monitoring functions

After a smart plug purely to bring an internet connection so existing lamps that don’t support smart bulb? You’ll be hard pushed to find a better option than the Philips Hue smart plug. It integrates with any Hue smart lighting you already have in your home, and can be controlled through the Hue app.  Even better, it's compact and can be used with Alexa, Googl Assistant or HomeKit.  

As smart plugs go, it’s one of the more expensive models we’ve tested  - especially if you don’t already have a Hue bridge, which ensures the plug can be controlled away from home. It also doesn’t offer any energy monitoring feature either. 

That said, it's a great buy for anyone looking to make existing lamps smart.

Wireless connection type: Wi-Fi

Reasons to buy

+
Small, neat design

Works with Alexa, Google Assistant and HomeKit

Reasons to avoid

-
Needs Hive Hub or Active Heating
-
Some hiccups during initial setup

Hive began as a manufacturer of smart thermostats (opens in new tab), but has grown into one of the biggest names in smart home devices of all kinds, including lights, cameras, locks and plugs. It's one of the most affordable ecosystems to get into - cheaper than Philips Hue (opens in new tab), if you're interested in trying smart lighting.

The Hive Active plug requires either a Hive Active Heating thermostat or Hive Hub, but once you have that, it's simple to set up and use. You can create a schedule (with up to six time slots per day), trigger the plug using the Hive app on your phone, or link it to a Hive switch or sensor. It also works with Alexa, Google Assistant, and HomeKit.

The Hive Active Plug is also relatively small, making it one of the most discreet (if not stylish) options available. However, we did run into some initial hiccups during set up[, so you may need to persevere.

The best smart light switch

Specifications

Dimensions: 5 x 3.3 x 1.5 inches
Wireless connection type: Wi-Fi

Reasons to buy

+
Sleek design
+
Simple to use
+
Works with Alexa and Google Assistant

Reasons to avoid

Bulky
-
Won't fit all switches in your home
-
No HomeKit support

Smart light switches mean any lights in your home, even those that can't have the bulbs swapped for smart versions, can be controlled by your smartphone or a voice assistant. 

The sleek-looking TP-Link HS200 Smart Wi-Fi Light Switch is a well-designed, easy-to-use switch that gives a satisfying click, just like old-fashioned models, when pressed. 

But the similarities with old-school switches end there. This switch taps into an app called Kasa that lets you create different scenes that turn on or off certain lights, or set lights to turn on when your home's motions sensors detect movement, for example. 

The switch also works with Amazon Alexa and Google Assistant, but there's no HomeKit support.  It's a bulky device and as a result, we found it wasn't compatible with every switch in our home. So we recommend ensuring that it’ll fit before buying the switch, or at least making sure that the store you buy it from has a pretty good return policy.

Unfortunately, this switch is currently only available in the US.

The best simplistic smart plug

Specifications

Dimensions: 3.9 x 2.1 x 2.4 inches (US) / 10 x 5.3 x 6.2 (UK)
Wireless connection type: Wi-Fi

Reasons to buy

+
Simplistic smart plug
+
Easy-to-use app
+
Compatible with Alexa, Google Assistant and HomeKit

Reasons to avoid

-
Need additional hub and remote
-
No energy monitoring

If you're looking for a simplistic smart plug, then head to your local IKEA and check out the brand's TRÅDFRI range of smart home products, which includes this minimal but reliable smart plug on offer. 

It features a single socket that can be plugged into a power source and controlled via the IKEA Home Smart app. However, unlike most of the smart plugs on this list that connect directly to your home Wi-Fi network, it requires the Tradfri gateway and a Tradfri ‘steering device’, which makes this less of an im[pusle purchase and more of a considered buy. 

Once hooked up, the smart plug can be controlled using the IKEA Home Smart app, or thanks to integration with Alexa, Google Assistant, and Siri (via HomeKit), your voice. It lacks features such as an Away mode or energy monitoring, but for those that want to keep it simple, it's a good choice.

How we test smart plugs

To identify the best smart plugs and switches you can buy right now, we evaluate how easy they are to install and control. We assess how responsive they are to being controlled  from a smartphone, both when we’re away from home and close by. We also check which voice assistants each model integrates with and whether they integrate with Alexa, Google Assistant or Siri, and how effectively Alexa, Google Assistant and Siri respond to commands related to the smart plug. 

We also evaluate each design on how durable it is, and any extra features such as energy monitoring and Away modes that control the plug at random times in a bid to simulate occupancy.  We also assess any extra kit such as hubs that’s also available for the smart plugs and consider whether it requires reading a thick instruction manual before use. 

Best smart plugs and switches FAQs

What to consider when buying a smart plug or smart switch

When selecting the best smart plug or smart switch for you, there are a number of aspects that should be considered before plumping for a particular model

Start by thinking about how the smart plug or switch is installed. Most smart plugs simply connect to an existing outlet, however, there are some available that replace your existing outlets, just as smart switches replace the existing wall switches that control your lights. These smart plugs and switches look stylish but they require much more DIY expertise, so you may have to employ a professional. 

With smart plugs, it's also important to consider the number of outlets a smart plug offers. The majority will have one, but if you have several devices close together than you want to control from your smartphone, a powerstrip, which can have up to four smart outlets in one device, will be a more cost effective solution. 

Also consider if you need the ability to monitor how much energy a device connected to the smart plug is using, and if so, does the smart plug work out the subsequent cost if you enter your energy tariff details, too. 

Some smart plugs and smart switches connect to your smartphone using Bluetooth, but that means you’ll only be able to control them if you’re close by. However if you’re the forgetful type that struggles to remember to turn devices off, a model with Wi-Fi built-in or that uses a bridge to connect to the internet and relay instructions from the cloud, will ensure it can be switched on or off  even if you’re no longer at the property. 

Not all smart plugs and smart switches integrate with all voice assistants, so check if a model is compatible if you already use a voice assistant in your home, and whether it will integrate with other smart home devices you already own such as home security cameras, video doorbells and smart lights.

What is a smart plug or switch good for?

A smart plug or smart switch is ideal for making any standard appliance smart so it can be controlled from an app on your smartphone. Perhaps you want to be able to brew your coffee without having to get out of bed, or perhaps you’re forgetful and are looking for a way to switch your hair straighteners off after you’ve left the house.

It connects to an existing power outlet and can be used with any appliance that has a standard plug on it - the possibilities are endless. Smart plugs can also be useful for monitoring how much energy an appliance is using. The figure, which is usually in Kwh can be viewed in the companion app. However, some smart plugs also allow you to add the energy cost and work out a monetary value for this energy usage too. 

What are smart plugs and how do they work?

Smart plugs allow you to power an electrical socket on or off from your smartphone, even when you’re not at home. Some use Bluetooth to allow you to use an app on your smartphone to control them, while others connect to Wi-Fi and use internet access to relay the command. 

Smart plugs come in two styles; the simplest and most common versions plug into an existing power outlet, with the likes of Amazon, Philips Hue, We-Mo, and even IKEA producing this design of smart plug. 

Alternatively, opt for a smart outlet that replaces your existing power outlet. However, you won’t have as many models of this type of smart plug to choose from, and you’ll need to access your home’s wiring to replace these, which will mean calling in a professional. Find out more in our article What is a smart plug, and how it can stop your fear of leaving the coffee maker on?

Do smart plugs and switches save energy?

Smart plugs and switches can save you money, but only if you’re the sort of person that forgets to turn off electrical devices. For example, if you leave your laptop constantly on charge, even when the battery is full it will continue to use energy, or perhaps you regularly forget to lights, side lamps, or the radio off when you leave the room? If so, then using a smart plug or switch could be the answer. 

Do smart plugs and smart switches work with Alexa (and other voice assistants)

Many smart plugs snd smart switches will work with Amazon Alexa, as well as Google Assistant and Siri so you can use your voice to control the gadgets, either by asking a smart speaker, or smart display, or by using the voice assistant on your smartphone or tablet. 

You can also create automations controlling several smart home devices at once with one command, or when a certain situation happens. For example, if your home security camera detects motion,  a DAB radio connected to a smart plug could switch on or a smart switch will automatically illuminate the lights, to give the impression  there’s someone at home. 

It’s worth noting that not all smart plugs and smart switches work with all voice assistants, so if your smart home is well established, make sure you opt for a model that integrates with your current setup.
