Which type of tariff is right for you?

A tariff is the way you get charged for your energy.

Choosing the right tariff for you can help reduce what you pay for your energy.

To help you work out what’s best for you, we’ll explain:

  • what the different tariffs are, and
  • how they work.

Electricity tariffs

There are three types of electricity tariffs:

  • single rate
  • time of use (including flexible pricing), and
  • controlled load.

Single rate tariffs

With single rate tariff offers there are no peak or off-peak periods. This means that you pay the same rate whatever time of day you use energy.

The rate is usually lower than the peak rates of a time of use or flexible pricing tariff. This means a single rate offer could be a good choice if:

  • You are at home a lot in the evening Monday to Friday. 
  • You need to use your appliances more Monday to Friday, like your washing machine or dishwasher.

Single rate tariffs are sometimes called:

  • flat rate
  • standard rate 
  • anytime rate, or
  • peak rate.

Single rate tariffs are available to everyone. You don’t need a smart meter to get a single rate tariff offer.

Time of use tariffs

A time of use tariff means that electricity costs different prices at different times of the day.

  • Peak—electricity costs the most. Peak rates usually apply in the evening on Monday to Friday. 
  • Off-peak—electricity is cheapest. Off-peak rates usually apply overnight on Saturday and Sunday.
  • Shoulder—electricity costs a bit less than peak. Shoulder rates usually apply in between peak and off-peak periods.

A time of use tariff offer could be a good choice if:

  • You are out a lot in the evenings Monday to Friday. 
  • You are at home during the day or on weekends. 
  • You use your appliances on the weekend, like your washing machine or dishwasher.

Some retailers have even more time periods than peak, shoulder and off-peak—for example, a flexible pricing tariff.

Flexible pricing tariffs are not available in all areas yet. You will only be able to search for flexible pricing tariff offers on Energy Made Easy if they are available in your area.

Retailers will tell you the start and end times of the different periods for their time of use offers in the Energy Price Fact Sheet or the retailer's written summary of the offer.

To get a time of use tariff offer, you need a meter that measures your electricity usage at different times of the day. For example, a smart meter or time of use meter.

Controlled load tariffs

For some appliances you can be charged a controlled load tariff, like:

  • slab or underfloor heating, or
  • electric hot water systems.

This means that the retailer charges a rate just for that appliance and the energy it uses. Often that appliance has its own meter.

It is usually only for appliances that run overnight or in off-peak times. So controlled load rates are usually lower.

Controlled load is sometimes called:

  • dedicated circuit consumption, or 
  • off-peak.

Gas tariffs

Gas offers are only available with single rate tariffs.

Most gas offers use tariff blocks. A tariff block is how the retailer charges you for the amount of gas you use.

This means you pay:

  • one rate or cost for the first part of your usage, then 
  • a different rate or cost for the next part (or parts) of your usage.

Blocks can apply to:

  • daily 
  • monthly, or 
  • quarterly usage.

Some gas offers have different rates for different times of the year, called seasonal rates. These rates are usually higher in winter.
