Standby power—also known as vampire energy—is one of the most overlooked sources of wasted electricity in UK homes. From phone chargers and routers to microwaves and gaming consoles, countless devices continue to draw power even when they’re not in use.
The result? UK households lose an estimated £50–£100 per year to standby electricity. But with the right smart plug or timer socket, you can automate shut-off times, reduce energy bills, and take control of your power usage—without changing your routine.
This guide covers the best budget smart plugs and auto-off sockets available in the UK, all under £20, with practical tips for setup and savings.
What Is Standby Power—and Why It Costs You
Standby power refers to the electricity consumed by devices that remain plugged in but aren’t actively operating. Think TVs on standby mode, chargers left in sockets, or printers waiting for a job. Even when idle, these devices draw a small but constant current.
According to the Energy Saving Trust, standby power can account for up to 10% of a typical UK household’s electricity bill. That’s money spent on nothing—and it adds up fast.
How Smart Plugs and Timer Sockets Help
Smart plugs and timer sockets are simple, affordable gadgets that let you control when devices turn on and off. They’re ideal for reducing standby power and automating your home’s energy usage.
Types of Energy-Saving Plugs:
- Smart Wi-Fi Plugs: Controlled via app or voice assistant (Alexa, Google Home). Schedule on/off times or use remote control.
- Countdown Timer Sockets: Automatically shut off after a set duration—perfect for overnight charging.
- Mechanical Timer Plugs: Set daily on/off cycles using a dial. No Wi-Fi required.
- Smart Plugs with Energy Monitoring: Track real-time power usage and identify energy-hungry devices.
These plugs work with everyday appliances—kettles, lamps, routers, fans, heaters, and more. And most cost less than a takeaway.

Setup Tips for Maximum Savings
- Start Small: Try one plug on a high-use device like a phone charger or kettle.
