Energenie ENER007 Energy Saving Power Meter Review (2026)

The Energenie ENER007 is a standalone power monitor that sits between your wall socket and any appliance. It is designed to provide visibility into electricity consumption, displaying metrics such as watts, volts, and total kilowatt-hours (kWh). Unlike smart plugs that require an app, this device uses a built-in LCD screen to show real-time data, making it ideal for users who prefer a local, privacy-focused solution for monitoring appliances like fridges, TVs, or heaters.

In testing, the ENER007 is particularly effective at catching 'vampire' loads—the small amounts of power devices consume when in standby. The large screen is readable, though the menu navigation can feel clunky when cycling through the eight different display modes. It is physically robust but can be bulky, occasionally blocking the adjacent socket on a standard UK double wall outlet depending on the plug shape of the appliance being monitored.

For the average UK household, this device is unlikely to save energy on its own, but the data it provides can lead to significant changes. By identifying a single old appliance left on standby that consumes 10W unnecessarily, a user could save roughly £20-£25 per year at current price caps. It is most effective when used to decide whether to upgrade an old, inefficient appliance or to prove the value of switching devices off at the wall.

Installation involves simply plugging the monitor into a UK 13A socket. No Wi-Fi or hub is required, though you will need to manually input your current unit cost per kWh from your energy bill if you want the 'Cost' feature to be accurate.

The device itself consumes less than 0.5W to operate, meaning it costs less than £1.50 per year to keep plugged in permanently.
