WattLock vs smart plugs
Updated October 2026 · WattLock UK team
Smart plugs and WattLock solve different problems. Here's the difference in one minute.
Quick answer
Smart plugs switch single appliances on and off by app. WattLock plugs into one socket and works on the whole circuit with no app. Many homes use both.

- Need Wi-Fi and an app
- Save energy by switching things off on a schedule
WattLock

Use both
Smart plugs are great for timers; WattLock covers the circuit. They work happily side by side.
Different tools for different jobs
Smart plugs are excellent for control: turning a heater off at 10pm, switching lamps on when you're away, or making sure a games console isn't left on standby. They only affect the single appliance plugged into them, and they need an app and Wi-Fi.
WattLock is designed for people who don't want apps or schedules. It covers the socket circuit it's plugged into and stays put. Many households use both: smart plugs for specific appliances, WattLock on each circuit.
Which suits you?
- Comfortable with apps and want timers? Smart plugs.
- Prefer no apps and minimal fuss? WattLock.
- Want both control and a circuit device? Use them together.
