Households with TVs have been warned that they are losing out on around £13.61 per year. Most UK households have TVs, and many of them are incredibly smart devices that not only carry channels, but let households stream movies, shows, music and audiobooks. TVs are among the devices that use up quite a bit of energy in the house, and they cost money even when they are in standby mode, much like other appliances that don't need a constant power source.

Energy experts at Electric Radiators Direct have revealed that the simple mistake of not unplugging common appliances can cost households quite a bit. Households are spending an average of £130 more per year when they don't unplug devices when they're not in use, a recent study found. This includes TVs, which they say cost more than £13 per year on average when left plugged in all of the time.

According to the study, the largest energy guzzlers are:

• Games console: £32.42


• Gaming PC: £20.96


• Desktop computer: £18.15


• TV: £13.61


• Speaker/Digital radio: £9.51


• Oven: £7.78


• Kettle: £4.97


• Microwave: £4.75


• Air fryer: £3.89

Energy efficiency expert Stephen Hankinson from Electric Radiators Direct said: "Putting something into standby mode is not the same as totally switching off a device or unplugging it. You're only really putting the device to sleep.

"This means that it will be drawing out some electricity in the background, which is where the phrase 'vampire device' comes from."

He added: "It sounds so simple but switching your appliances off at the wall really is the best way to ensure you're not spending your hard-earned income on keeping things in standby mode.

"The cost of a couple of coffees might not concern you, however, £132 is a big food shop, two tanks of petrol or even a nice meal out. There really are much better ways to use this money than giving it to the energy companies."

The cost of leaving your TV in standby mode is determined by several factors, including the make of the TV, its size and capabilities, and the energy efficiency of your home. This means that, for some households, the annual cost of leaving a TV on constant standby when not in use will be less than £13.

However, for some households, that annual cost could be higher.
