Looking for the best power usage meters for tracking electricity UK 2025? These devices reveal how much energy your appliances really use — helping you spot hidden costs and cut your bills with precision. Whether you’re curious about a fridge’s overnight draw or testing the savings from your new smart plugs, a power meter is the simplest way to take control.
🔹 Why Every Home Should Have a Power Meter
Most people underestimate how much “vampire power” their devices use — that’s the electricity consumed while gadgets sit on standby. A meter lets you see this in real time. Plug it in, connect your device, and you’ll instantly get readings for watts, kWh, amps, and total cost.
💡 Example:
A TV left on standby 24/7 might use 50 kWh per year, costing around £15. Catching just three of those hidden drains easily saves £40–£50 annually.
