Leaving electrical devices such as televisions and games consoles on standby can cost up to £80 a year in electricity bills.

Turning appliances off when they are not in use would save UK homes £1.7billion a year, according to the Energy Saving Trust,

Despite the cost, a poll found that three-quarters of homes with a spare television leave it on standby.

A games console on standby can cost up to £30 a year, but nearly two-fifths of console owners leave them on, according to the Ipsos Mori poll.
