A smart plug sits between your wall socket and whatever you want to control, turning any ordinary lamp, fan or appliance into something you can switch on and off from your phone. They're one of the cheapest and easiest ways to start with smart home gadgets, and most need nothing more than a plug socket and a WiFi connection to get going.
The difference between a good smart plug and a frustrating one usually comes down to the app it uses, how reliably it stays connected, and whether it plays nicely with voice assistants like Alexa or Google Home. Energy monitoring is a handy bonus if you want to see what your appliances actually cost to run, but it's not essential for everyone. Reviews and rating counts matter more than spec sheets here, since reliability over months of daily use is what separates the good ones from the rest.

Smart Plugs Buying Guide — What to Look For
Decide if you need energy monitoring
Some smart plugs simply turn devices on and off, while others also show you how much electricity they're using. If you're curious about running costs for things like heaters, fridges or tumble dryers, an energy-monitoring plug is worth the small extra cost. If you just want to schedule a lamp or switch off a device remotely, a basic plug will do the job fine.
Check app and voice assistant compatibility
Most smart plugs work through their own companion app, and many also support Alexa or Google Home for voice control. Before buying, check the app has decent reviews on its own merits, since a clunky app can make an otherwise good plug annoying to use. If you already use a particular smart home ecosystem, confirm compatibility before adding to your basket.
Think about Matter support for future-proofing
Matter is a newer smart home standard designed to make devices from different brands work together more easily. Not every smart plug supports it yet, and it isn't essential right now, but it's worth considering if you plan to build out a wider smart home system over the next few years.
Multi-packs often make more sense than singles
If you're planning to fit out more than one room, buying a two-pack is usually cheaper per plug than buying singles. It also means you can standardise on one app rather than juggling several, which makes scheduling and automations much simpler to manage.
Our Final Verdict
For most people, the Tapo P100 2-Pack Smart Plug at £15 is the one to buy, thanks to its combination of low price, huge review count and consistently high rating.
If you just want the cheapest way into smart plugs, the STATUS Smart Plug Wi-Fi Adaptor at £8 covers the basics without asking you to spend much at all.
