Upgrading to a smart light switch UK can significantly enhance your home's lighting efficiency and convenience. If you’d like the benefits of smart lighting without having to invest in smart bulbs, then smart light switches are the way to go.

Before I begin, here’s a quick run through of important things to know …

  • Generally speaking, you have the choice between smart on/off and dimmer switches, if you are replacing your existing switch. 
  • Some switches work off Wi-Fi and don’t need a smart hub, while others are Z-Wave or Zigbee compatible.
  • Some switches require a neutral wire to provide constant power while others don’t, so best to check that first and foremost. Be careful as products that advertise that they don't need a neutral wire, may actually need one somewhere in the lighting circuit.
  • If you would like to keep your existing light switches, you can install a mini-relay behind the switch or above the light fixture, which you can then control via a smart hub.
  • If you already have Philips Hue smart bulbs, there are also light switches available for them, to give the more traditional experience

Best UK Smart Dimmer Switch

8.7
Top Smart Dimmer Switch
1-4 Gang Dimmers Available

The Lightwave Smart Series Dimmer allows you to control the lighting in your home via the Lightwave app or voice assistants like Alexa, Google Assistant, or Siri. It features energy monitoring, easy installation with no extra wiring, and multiple control options.

Top Features
  • Compatible with dimmable LED bulbs
  • Multiple Lightwave device triggers
  • Amazon Alexa/Google Assistant/Apple Homekit compatibility

The Lightwave LP21WHMK2 is a smart dimmer switch that allows you to control the lighting in your home through your smartphone or voice-controlled assistants such as Alexa, Google Assistant, and HomeKit. The dimmer switch is simple to install and requires no extra wiring – it can work without a neutral or earth wire.

It replaces your existing light switch and can be paired with the Lightwave Link Plus to control your lights from anywhere. You can set schedules, create timers, and adjust the mood of your home room by room. The dimmer switch is compatible with dimmable LED bulbs and requires a Wi-Fi router with broadband internet connection.

The biggest problem I have with the Lightwave smart dimmer switch is you really need to buy the Lightwave hub to get the switches full functionality. Unfortunately the Lightwave hub is quite expensive (more than £100) so suddenly this smart dimmer becomes a more significant investment.

Scenes / Routines

With the Lightwave app, you can also create what they call “Magic Buttons” to trigger multiple Lightwave devices with a single press. You can also set up a gentle wake-up call in the morning by automating your lights. The device is available in white metal and is compatible with iOS and Android devices.

It has a maximum dimmable load of 280W (non-LED) and a current rating of 1 Amp. It comes with a 2-year manufacturer's warranty.

Its worth noting that not all LED bulbs are compatible, and the switch can reset itself if the resistance in the circuit is too low.

It supports 2-way switching via the grouping feature in the app.

What I liked
  • Nice looking product with a modern design
  • Works well with Alexa, Google Assistant and Apple Homekit
  • Technical support are quite helpful when needed
What I didn't like
  • Expensive when you take the additional hub into account
  • Compatibility issues with some LED bulbs

With the SONOFF Smart Light Switch, you can take full advantage of the smart scene feature. The smart scene integrates multiple triggers in a single set up. You can set up one SONOFF device to trigger the other one on/off. Alternatively, you can choose to run all devices at once with a single command.

  • Timing and Scene Functionality

The SONOFF Wi-Fi Touch Wall Light Switch is a smart switch is compatible with both Amazon Alexa and Google Assistant, so you can use voice commands to turn your lights on and off. If you prefer, you can also control your lights via the Alexa or Google Home app, or via the eWeLink app, which is available for both iOS and Android devices.

The switch doesn't require a hub, and it works with any 2.4GHz Wi-Fi router. There can be issues initially pairing if you also have a 5GHz band configured on your router.

A neutral wire is required for this switch to work, so best to check your wiring beforehand.

With the timing function, you can set your switch to turn your lights on and off automatically according to your schedule. You can create smart scenes, so one SONOFF device can turn another one on or off. This allows you to control multiple devices with just one tap.

Build Quality and Materials

The SONOFF switch is CE, RoHS, and FCC certified and features a tempered glass panel and a PC fire-retardant housing. The build quality has received mixed reviews, with some people impressed with its sleekness while others not happy with the quality.

From an installation point of view, you can use it to replace your old, traditional wall light switch as it fits in the same 86-type box, so you don't have to worry about making any major changes to your home's electrical system.

It also supports 2-way switching via the grouping feature in the app.

What I liked
  • Integration with Google Home and Alexa works well
  • No additional hub required
  • Product is generally easy to set up (if you know what you're doing!)
What I didn't like

Top Features
  • Dark blue LED light
  • 2.4GHz Wi-Fi operation
  • Tempered glass touch screen

With its tempered glass finish the TCP Smart Light Switch can be used to controlling multiple light fixtures. It can be controlled by voice through Amazon Alexa or Google Home, through an iOS or Android app, or through touch. While it says its compatible with Siri, some users had problems connecting it to Apple HomeKit and Siri Shortcuts.

Similar to the SONOFF, the TCP switch also requires a neutral wire so I recommend checking out what wires you have in the box.

Its worth noting this switch requires a deeper back box than usual. It can work with mains voltage lighting and offers a variety of features including timers and schedules, so you can control your lights even when you're not home. The switch is rated at 13 A and comes with a 1-year manufacturer guarantee.

As its a Wi-Fi switch a smart hub is not needed.

What I liked

Features of Smart Light Switches

Voice Control

Some of the best UK smart light switch options are compatible with voice control tools. Some of the common ones include IFTTT, Amazon Alexa, Google Home/assistant, and Apple Home Kit/Siri.

This makes it easy for you to control the lighting hands–free. All you need to do is mutter out the voice commands. This function allows you to integrate your home lighting into your smart home system as well.

Remote Control

What makes smart light switches stand out is their remote control feature. Some smart light switches are Wifi controlled – allowing you to connect them to your home’s Wifi network. This means that you can then control them remotely using their proprietary app. Others work off Z-Wave or Zigbee protocols so you can integrate with a compatible smart hub.

Depending on the light switch design and capacity, this feature doesn’t only allow you to remotely switch your lighting on and off. You can also use this feature to set up timing schedules and tailor your home lighting habits based on your needs.

Technology

Most UK smart light switches use technology that you may already be using in your home. So, before investing in one, it is a good idea to cross check this information – so you can figure out how to take advantage of the technology and ensure effective functionality.  

Generally, a smart light switch will be compatible with at least an iPad, android device, Nest, or Ecobee in your home. For example, Apple Homekit devices such as Ecobee or iPad are perfect for iDevices and in-wall outlets. SmartThings technology on the other end supports Z-Wave and Zigbee devices.

Switch or Plug

When shopping for smart light switches, you will come across switches and plugs. Switches come with the convenience of working as regular light switches with natural operation whilst boasting features such as app remote control and timing automations. 

They work great for those who want to automate their regular light fixtures. Smart plugs on the other end tend to be more flexible as you can plug them with whatever device you want – great for lamps!

The Verdict

I hope this guide was useful in helping you choose a smart light switch for your UK or Irish home. Installing a smart light switch UK is an easy way to modernize your home and control lighting with just a tap.
