Most of us know to switch off the lights when we leave a room, but fewer people think about what happens when appliances are left on standby power. TVs with the red dot glowing, gaming consoles left on pause, chargers plugged in long after your phone is fully charged, they’re all quietly using electricity. While each device may only sip a small amount of power, across an average UK household those sips quickly add up to real money on your energy bills.
Below, we’ll explore how much power is used on standby, which appliances are the worst offenders, and how to reduce your energy costs without making your home less convenient.
What is Standby Power?
Standby power is the electricity consumption of electrical appliances when they’re left plugged in but not in active use. It’s sometimes called “phantom load” or “vampire power.” Even when a device looks switched off, internal circuits remain active.
Examples include:
- A TV on standby waiting for the remote signal
- A router that is never switched off
- A phone charger left plugged in after the phone is fully charged
- A gaming console left on rest mode overnight
Your smart meter may show a base level of energy consumption even when you think everything is off. That’s standby power in action.
How Much Power Does a TV Use on Standby?
A modern TV on standby uses around 1–3 watts, which doesn’t sound like much. But multiply that across the year and you could be paying £10–15 just for one television to sit idle. Older TVs can use far more. Add in a sound system, satellite box, and streaming stick, and your energy consumption is higher than most people expect.
In an average UK household, appliances left on standby can account for 9-16% of total electricity consumption. That’s not insignificant, especially with today’s price cap keeping bills higher than they used to be.
The Hidden Cost of Gaming Consoles and Chargers
Gaming consoles are some of the worst culprits for standby power consumption. A console left in rest mode can use between 10–15 watts, and even more if background downloads are running. Over a year, that could cost £30–50 depending on your tariff.
Chargers are another source of wasted energy. Leaving a phone or laptop charger plugged in when it’s not connected to a device still draws power. It may be small, but if you’ve got multiple chargers across the house, the costs build up.
Do Devices Left on Standby Really Matter?
Yes, especially when combined. Here’s what standby power consumption might look like in a typical home:
- TV on standby: £15 per year
- Gaming console rest mode: £40 per year
- Wi-Fi router: £20–30 per year
- Kitchen appliances with clocks/displays: £20 per year
- Assorted chargers: £10 per year
Suddenly, you’re looking at £100–120 annually just for devices on standby. That’s money you could save without any loss of comfort or convenience.
How to Reduce Standby Power and Save Money
You don’t need to start unplugging everything obsessively, but some simple steps can reduce your energy usage significantly:
- Unplug fully charged devices: Once your phone or laptop hits 100%, disconnect the charger.
- Switch off at the wall: Turn off TVs, gaming consoles, and kitchen appliances when not in use.
- Use smart plugs: These let you cut power to devices on a schedule or via your phone. Perfect for appliances you forget about.
- Group appliances: Plug your TV, soundbar, and console into a single power strip with a switch for easy control.
- Upgrade inefficient kit: Some older appliances are much less energy efficient than modern replacements.
