How much electricity can I save?
In small-scale trials of home energy monitors, customers have typically saved five to 15 per cent in the first year of owning a monitor, which could be ￡25 to ￡75 off a ￡500 bill.
The Energy Saving Trust estimates that households in the UK waste around 8 per cent of their electricity bill on standby power. That’s about ￡40 a year for an average household. In addition, ￡170 million a year is wasted through leaving lights on in unused rooms.
