Economy 7 is a specific energy plan that is designed to be cheaper during certain periods of the day, generally during the night. This is why it’s often referred to as a ‘time-of-use’ tariff. Generally, energy suppliers will have an ‘off-peak’ period from midnight to 7 am where they will charge you a lower rate. You will have to get a specific meter installed which will take separate readings from the day and night.
These tariffs are known officially as ‘differential tariffs’ which may help you pay less for your electricity. Economy 10 tariffs work in much of the same way that an Economy 7 does. It will have a certain off-peak period which is normally the same 7 hours, but 3 hours on top of that during the day. You will need to have a specific meter installed, so that it can take multiple readings per day, and there may be a charge for this.
Both of these tariffs are specifically designed to give you cheaper electricity rates during the night and more expensive during the day, you cannot use these with gas rates. Whether or not you should get these tariffs depends entirely on your energy usage. Broadly, they are for people who use a lot of electricity at night, such as watching TV, washing machines, or storage heaters which heat up overnight.
Except for having a different price during the day and at night time, Economy 7 and Economy 10 tariffs are relatively similar to other tariff types; you can get an Economy tariff that acts like a Standard Variable Tariff, where the day and night prices change with market prices, or you can take them on a fixed price energy tariff, that will set your day and night rates for the duration of your contract.

As outlined above, the downsides of these tariffs really depend on your energy usage. If you don’t have a storage heater or use electricity in the night, then it may not be beneficial to switch. Additionally, installing an Economy 7 or 10 meter may incur a charge, and should you want to switch back, you could be charged again for the meter installation. It’s important to therefore compare energy tariffs against your general consumption habits to see which tariff fits you the best.
There are two simple ways to find out if you are on these tariffs already. Firstly, if you check your electricity bill, there will be a section called ‘your electricity use in detail’, this will be divided into day and night readings if you are on an Economy 7 tariff. Secondly, you will have a specific meter which will have two readings and might have a label on it too.
There are two types of meter for Economy 7 and 10:
This is not a completely straightforward process because the provider will have to come out and install a new meter, which can mean additional charges. It’s important to contact your energy supplier to see what this cost will be and compare energy tariffs depending on your own personal energy consumption.
