Does it cost me money if I leave an appliance on standby?

In the table below, you'll find the average annual standby energy costs for a device on standby for 20 hours per day (that's 7,300 hours per year).

Turning all of this tech off at the wall will save you £20.40. Every little helps when you’re grappling with high energy bills, but it’s a far cry from some media reports claiming you could save £15 a year by turning off your TV alone.

* Always check the instructions for any appliances you aren’t sure. Some satellite and digital TV recorders may need to be left plugged in so they can keep track of any programmes you want to record.
