HOUSEHOLDS could save money by running their appliances at certain times.
Reducing energy costs is a priority for millions of households as the average annual gas and electricity bill has soared to £2,500 a year.
Over three million households with multi-rate Economy 7 electricity meters already save by putting their washing machines and other devices on at night.
That means if you can switch your electricity use to night time hours, you could make savings.
But under new plans unveiled by the National Grid, households who are not on these tariffs could also benefit from reducing their usage in peak times.
