Economy 7

Economy 7 allows you to pay different unit rates for your energy depending on the time of day. You pay one rate during the day and then a lower rate for 7 hours during the night.

An Economy 7 meter will display two readings:

  • ‘Low’ or ‘night’ reading
  • ‘Normal’ or ‘day’ reading

If you have an Economy 7 meter, you would also see a difference on your bills. If your electricity is charged at two different rates, one for day and one for the night, you’re on Economy 7.

If you have an Economy 7 meter, you don’t have to be on an Economy 7 tariff. If you would prefer to be on a single rate tariff, we’d charge you the same rate for both day and night. So you shouldn’t need to change your meter.

If you have a standard meter, then it's not possible to have an Economy 7 tariff as we have no way of measuring your different day and night usage.

Economy 7 can save some customers money. Whilst others can find the tariff more expensive as the day rate is higher than usual to balance the off-peak rate.

Whether it will save you money will depend on a few different factors:

  • When you use electricity – generally, you need to use around 40% to 50% of your electricity during the night for it to be cost-effective.
  • How you heat your home and water – If your home uses electric storage heaters and hot water tanks, then an Economy 7 tariff could work well if you heat them overnight to slowly release the next day. If you heat your home and water with gas, then an Economy 7 tariff could also help you save money. So long as you still use most of your electricity at night.
  • What appliances you own – It will be useful if your large appliances such as dishwasher, washing machine and tumble driers have timers. This means you can set your appliances to turn on when the off-peak hours start, making use of the cheaper electricity.
  • Your lifestyle - if you often work shifts or nights and use most of your electricity at night anyway, then Economy 7 could help you save money.

Economy 7 times will change depending on where you live, the meter and which energy supplier you’re with. It typically falls between 10pm and 8.30am.
