Brits could save £1.7 billion a year by switching their appliances off standby say The Energy Saving Trust.

The biggest culprits are televisions and games consoles which when left on permanent standby can cost a whopping £45-80 a year.

Almost all electrical and electronic appliances can be turned off at the plug without upsetting their programming. You may also want to think about getting a standby saver which allows you to turn all your appliances off standby in one go.

Check the instructions for any appliances you aren’t sure about. 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.
