The full guide

Economy 7 is an electricity tariff with a cheaper rate for seven hours at night and a dearer rate during the day. It suits a home that uses a large share of its electricity at night, such as with storage heaters. If most of your use is in the day, it can cost more than a single-rate tariff.

How to tell if you have it

  • Your bill shows two electricity unit rates, often called day and night, or normal and low.
  • Your meter shows two readings, or a smart meter records both.
  • You may have storage heaters or a hot water cylinder set to heat overnight.

When the night hours are

The seven hours are set by your region and your meter, usually some time between 10pm and 8:30am. Some meters stay on winter time all year, so the hours move by one hour in summer. Your bill or your supplier can tell you yours.

Readings and bills

Give both readings each time, day and night. If a bill uses only one, or swaps them, tell your supplier. Economy 7 tariffs on a standard variable rate are covered by Ofgem’s price cap, which limits each unit rate and the standing charge, not your total bill.

How Wisemium helps

Upload your energy bill to Wisemium and it reads the supplier, tariff, unit rates and standing charges for you to confirm, and keeps them with any fixed term end date. Wisemium does not change your meter or tariff; your supplier does.
