All electric tariffs: One meter with two rates

What is Economy 7 or Domestic Economy?

Economy 7 and Domestic Economy are tariffs where you get one meter which has two rates. One rate records all energy used during the day, and the other rate records energy used overnight. Economy 7 is found in England and Wales while Domestic Economy is found in Scotland. 

You'll make the biggest savings if you have storage heating and hot water, which you can heat up on your off-peak, overnight rate. This way, you'll have heating and hot water throughout the day. Storage heaters usually only heat up when the off-peak rate is live. Hot water immersion heaters can also be set up in the same way, but some may have a timer instead.  

All the electricity you use during the off-peak times is charged at a cheaper rate, not just your heating and hot water. Energy used outside of these times is more expensive than our standard rate, so we'd advise you to shift your energy use  to your off-peak hours. 

What are the off-peak times?

Economy 7 off-peak times differ depending on where you live. In most cases, the off-peak hours are in one overnight block, starting from around 12am during winter months, although this may change by one hour during British Summer Time.

In some areas the times might be split. You might get two shorter blocks overnight instead, or a small top-up boost during the day. If you’re unsure of your peak or off peak times, your energy supplier can confirm these. 

For Domestic Economy, in Northern Scotland the eight hour off-peak period runs between 11:30pm and 7:30am during GMT and 12:30am and 8:30am during British Summer Time.

In Southern Scotland, it’s 8.5 hours off-peak from 11.00pm - 7.30am during GMT and 12.00am - 8.30am during BST.

Heatwise

Heatwise is a tariff that offers 10 hours of cheaper electricity split across three periods each day. You'll likely know if you're on this tariff, as it's only available for approved, hard-wired loads. It also has to be in combination with the Standard Domestic or Standard Domestic plus Economy 7 option.

One tariff records all the electricity you use during the afternoon and the other records electricity used in the evening/night and boost period. To get the best from this particular energy tariff, you should set your heating to come on during the off-peak hours.

What are the cheaper off-peak hours for Heatwise?

You get three times over the day where your electricity is cheaper; one in the afternoon, one in the evening and one overnight.

Afternoons

• Monday to Friday – 3 hours between 1pm and 4.30pm

• Saturday and Sunday – 3 hours between 1pm and 5.30pm

Evenings

• Monday to Sunday – 2 hours between 5.30pm and 10pm

Nights

• Monday to Friday – 5 hours between midnight and 7am

• Saturday and Sunday – 5 hours between midnight and 8am

White Meter

A White meter is very similar to Domestic Economy but it’s found in parts of England and Wales. It provides 8 hours of off-peak electricity overnight for everything including storage heaters and hot water immersion heaters. 

When are the cheaper off-peak times for a White Meter?

You get your 8 hours of cheaper rate electricity for your stored heat between 11.30pm and 7.30am.

Evening & Weekend Tariff

Evening & Weekend tariffs offer cheaper off-peak electricity in the evening and at weekends. This means the energy you use during the day costs more than our standard rate, so it's great for people who are out during the day on weekdays.

This tariff works in a similar way to our other tariffs that have one meter with two rates. One tariff records all the electricity you use during the day on weekdays, and the other records electricity used in the evening and at weekends. This tariff is usually better for homes with gas or oil heating, rather than storage heaters.

What are the cheaper off-peak times for Evening & Weekend tariffs?

The times depend on whether you live in Wales, England or Scotland, have a look at the table below for your exact times. The weekend counts from Friday evening all the way through to Monday morning.
