Average electricity and gas consumption uk

Are you paying too much for your energy? Find out the average electricity and gas usage rates for UK households right here to see if you are paying more than you should be!


Average energy consumption rates in the UK can show you how much gas and electricity you should be using every year. If you are miles over the average rate for the size of your household, it is a sign that you could be wasting a lot of energy and should try to be more energy efficient to cut down on your bills.

These rates for the UK can also help you get an accurate quote when looking for a new energy provider. Remember: the more accurate your quote, the better you know how much you could save when you switch!

Average electricity and gas usage is calculated using ‘Typical Domestic Consumption Values’ (TDCV). These values are calculated and reassessed every two years by the energy regulator Ofgem. They were most recently reassessed in 2020.

Average electricity usage for UK households

Electricity is more expensive than gas, so if a lot of your household appliances run on electric (e.g. your boiler or oven), your energy bills will likely be higher than households that power such appliances with gas.

In general, electricity usage in the UK is lower than gas consumption. The table below shows the most recent annual average electricity usage UK figures for small, medium and large households.

Average electricity usage UK
Fuel Level of consumption Consumption
Electricity Low (1-2 bedrooms/flat) 1,800 kWh
Medium (3-4 bedrooms) 2,900 kWh
High (5+ bedrooms) 4,300 kWh

Average electricity usage for Economy 7

Customers on Economy 7 tariffs typically use more electricity than consumers with standard meters, prepayment meters or smart meters. The latest UK average electricity usage for Economy 7 customers are listed in the table below.

Economy 7 average electricity usage
Fuel Level of consumption Consumption
Electricity Low (1-2 bedrooms/flat) 2,400 kWh
Medium (3-4 bedrooms) 4,200 kWh
High (5+ bedrooms) 7,100 kWh

When getting a quote for an Economy 7 tariff, you will be asked for your typical electricity split, meaning what percentage of your average electricity consumption takes place in the day and how much at night. This is important as Economy 7 tariffs charge two different electricity rates: one during peak hours and one during off-peak hours.

The average electricity split for Economy 7 customers in the UK is listed in the following table.

Economy 7 peak/off peak split
Peak hours (day) Off-peak hours (night)
58% 42%

Average gas usage for UK households

As we mentioned earlier, households in the UK typically use more gas than electricity. In fact, the average gas usage for UK households is typically more than double than the average electricity consumption. As a result, the unit rate for gas is cheaper than the unit rate for electricity.

The table below shows the most recent annual average gas usage UK figures for small, medium and large households.

Average gas usage UK
Fuel Level of consumption Consumption
Gas Low (1-2 bedrooms/flat) 8,000 kWh
Medium (3-4 bedrooms) 12,000 kWh
High (5+ bedrooms) 17,000 kWh

What is the average daily energy usage?

The exact amount of gas and electricity that you use per day will vary depending on the appliances that you use, the day of the week (most households use more energy on weekends), and the season (average usage levels rise during the winter).

The following figures give an estimate of the average electricity usage and average gas usage per day in the UK.

  • Electricity: 8 - 10 kWh per day
  • Gas: 33 - 38 kWh per day

Average electricity and gas bill

Gas and electricity bills vary based on a number of factors, including:

  • The region you live in - unit rates and standing charges vary between areas
  • You energy supplier - suppliers charge different rates
  • Type of tariff you are on - variable tariffs are typically more expensive than fixed-rate tariffs
  • Your energy usage - the amount of energy you use will affect how much you pay

In the most recent estimate from March 2021, Ofgem found that the average yearly energy bill for a standard variable tariff paid for by direct debit totalled £1,042 for gas and electricity (dual fuel).

What are my costs made up of?

Ever wondered what you are actually paying for with your bill? Your energy bill is made up of two main costs.

1. Unit Rates

flame, bill, money

Both gas and electricity use is measured in kilowatt-hours (kWh) and the unit rate is the same thing as the price per gallon of petrol if you own a car. Gas and electricity prices are never the same, with gas being much cheaper per unit. If you have both in your home, you will end up using more gas than electricity because of heating and cooking.

Just keep in mind that the unit rate determines the cost of your usage which is the main part of your bill. Just like when you fill up your car and you try to find the petrol station with the best price per gallon, it’s worth going the extra mile to find a supplier with lower unit rates.

2. Standing Charge

Unlike your car, however, you don’t go out and fill up on electricity or natural gas, it’s delivered to you through the national grid instead. The standing charge is just that, a delivery fee for your energy, like a Netflix subscription that keeps your lights on for one flat daily fee.

While standing charges don’t increase with the number of kWh, they do accumulate daily so you should definitely keep an eye out for them.
