All the so-called “vampire” appliances silently draining cash from your bank account have been revealed and they could be costing households over £100 a year.
With energy prices still high in 2026, many Brits assume their bills should be easing. But experts warn that a hidden culprit could be quietly pushing costs back up.
A home energy specialist says everyday devices left on standby are still using electricity – even when you think they’re off.
“Those little standby lights and digital displays might seem harmless, but they’re constantly drawing power in the background.”
“Over a full year, that wasted energy builds up into real money leaving your pocket.”
So-called “vampire appliances” are electronics that continue to use power when plugged in but not actively in use -also known as standby energy.
Research suggests this wasted electricity can account for up to 23% of a household’s energy use, adding potentially £80 to £140 or more annually depending on usage.
More recent estimates in 2026 suggest the total impact could be even higher in some homes, with “phantom load” devices adding hundreds of pounds a year in extreme cases.
“Many households don’t realise how many devices are still running 24/7. Chargers, TVs, routers -they all add up.”
From living rooms to kitchens, the biggest offenders are devices left on standby or permanently plugged in.
Typical culprits include:
- TVs and smart TVs
- Set-top boxes and streaming devices
- Games consoles
- Wi-Fi routers (often left on constantly)
- Phone and laptop chargers
- Microwaves with digital clocks
- Coffee machines
- Smart speakers and smart plugs
- Printers and baby monitors
For example:
- A set-top box can cost over £30 a year on standby
- TVs can add around £9–£10 annually
- Microwaves and coffee machines each add several pounds more
Even small devices like chargers still draw electricity when left plugged in.
Wallis said:
“Individually these costs seem small -but together they can easily exceed £100 a year in wasted energy.”
The warning comes as UK households continue to face elevated energy bills, with price caps and usage costs still significantly higher than pre-crisis levels.
Typical homes use around 2,700 kWh of electricity annually, meaning even small inefficiencies can have a noticeable impact on bills.
Wallis added:
“With energy costs where they are, cutting out waste is one of the easiest ways to save money without changing your lifestyle.”
The good news is that tackling vampire devices is simple.
Wallis recommends:
- Switching appliances off at the mains socket, not just standby
- Unplugging chargers when not in use
- Using smart power strips to cut multiple devices at once
- Being mindful of always-on tech like routers and smart devices
He said:
“You don’t need expensive upgrades -just better habits. Turning things off properly can make a real difference.”
While each device may only cost a few pounds a year, the combined effect is significant.
Wallis warned:
“It’s one of the easiest leaks in your household budget to fix -but also one of the most overlooked.”
