What Is Economy 7?

Ecomony 7 is basically a cheaper charge for electricity. This cheaper charge is applied during the night. Electricity suppliers provide this because less electricity is consumed during the night and early morning and encourage users to use their appliances (most commonly washing machines) during the night. Thus the user saves some money.

The lower tariff typically starts from midnight thought to 7am in the morning. (Thus why it's called economy 7). During this time you can expect pay about a third less than you normally would. There are a number of appliances you  can use during this time to save money - why not get your plates clean too by putting on the dishwasher. Also why not set your water heater to heat during the night.
