What is the average energy consumption in the UK in kWh?

Average electricity and gas consumption varies greatly depending on use and season. In addition, the average energy consumption in statistics is often pulled up by a few households with high consumption.

What’s a kWh?
Before you can understand how much energy your home consumes, it’s important to find out a little more about how energy is measured. Household energy consumption in the UK is measured in terms of kilowatt hours, or kWh. A kilowatt is 1,000 watts. A kilowatt hour is a measurement that equals the amount of energy you would use if you had a 1,000 watt appliance running for an hour. So for example, if you had a 1,000 electric radiator on for an hour, it would use up one kWh.

Smaller appliances take a lot longer to consume a kWh. Even the brightest light bulb is normally only 100 watts. This means it would take 10 hours to consume 1kWh of energy. A 2,000 watt appliance on the other hand would have an average energy consumption of 1 kWh every 30 minutes.

What’s the Average Energy Usage UK?

Average energy consumption varies dramatically between households. Large, poorly-insulated homes, and those that are jam-packed with tech, are likely to use considerably more electricity than small, well-insulated properties. According to government figures, the average household in the UK consumes 3760 kWh per year. This figure has dropped over the last few years, dipping below 4,000kWh for the first time in decades in 2014. The average kWh per day in a UK household is in the range of 8.5 to 10 kWh.

This drop in average energy consumption is largely down to more efficient appliances and improved insulation. The increased popularity of smart meters has also made a lot of people more aware of the amount of energy they’re using. This has encouraged a number of households to cut their usage and reduce their energy bills.

How much is the average kWh in the UK?
The average daily consumption in a UK household is between 8.5 and 10 kWh. Many factors can influence this average energy consumption and the amount of electricity costs, such as the appliances that are used.

What is the average kwh usage per day in the UK?

The average daily consumption in a UK household is between 8.5 and 10 kWh. Many factors can influence this average energy consumption and the amount of electricity costs, such as the appliances that are used. A list of the energy consumption of different appliances you can find later on.

How is energy consumption changing year-to-year?

Total gas consumption in 2020 was 1.3% higher than in 2018. Unlike electricity, the household sector is the largest consumer, consuming 64% of total gas consumption in the UK in 2020.

Energy Intensity change

Energy consumption per unit of production is also called energy intensity. This shows how efficiently energy is used over time. Changes in energy intensity occur for a variety of reasons: Process changes, technological change and structural changes. In the household sector, there has been a general downward trend in domestic consumption since 2005, which can be attributed to improvements in energy efficiency measures. The decline in the passenger and freight transport categories in 2020 is a direct result of the Covid 19 pandemic.

What appliances use the most electricity?

Most of the electricity used in your home will be consumed by your appliances. Some of these appliances are surprisingly energy hungry, even when they’re on standby.

In general, the gadgets that use the most electricity are those that heat and cool things. So your fridge, freezer, kettle, toaster and electric boiler are likely to contribute the most towards your average electricity consumption. Appliances like lamps, TVs and stereos generally use much less energy than other electronics. Although leaving them on standby does add significantly to their average consumption.

According to Ofgem, the typical household of 2.4 people uses 2,900 kWh of electricity a year at an average cost of 20p/kWh. This translates into an average electricity bill of £580 per year or £48.33 per month. To calculate your energy cost you can multiply the wattage by the number of hours you use it and then divide the result by 1,000. A very simple example: If you pay 17 pence per kWh and your microwave has 1,000 watts, it will cost you 17 pence to run it for one hour.

How is my bill calculated?
Your energy consumption is the most important part of your bill. Your energy supplier charges for each unit or kilowatt hour (kWh) you use, so the more you use, the more you pay.

How much energy do we produce and consume?

The amount of energy the UK produces varies year by year. For a long time, the UK was fairly self-sufficient when it came to energy production. However, as the North Sea oil reserves have begun to dwindle, the country has started relying on imports for an ever-larger proportion of its energy needs.

Energy consumption and production in the UK

Energy in the UK comes from a number of different sources including fossil fuels, renewables, gas and nuclear. At the moment, the majority of our energy still comes from fossil fuels. Although over the past decade, the percentage of energy derived from fossil fuels has dropped significantly. This has mostly been caused by the rise of renewable energy and more efficient green energy production processes.

Energy consumption and production in the UK
Fuel 2011 2018
Gas 40% 39%
Coal 30% 5%
Nuclear Power 19% 19%

Why is Ofgem average for gas used per year so low? 12000Kwh when I only use gas for heating and hot water and my annual is over 20000Kwh. Your house averages are more realistic.

My projected electricity usage for the year is 13,133kw I live in an apartment with 3 bedrooms 1 bathroom 2 en-suite 1 large lounge with Vaulted ceilings 1 small kitchen. I only heat my lounge with 3 storage heaters (new this year supplied by the eco energy scheme) I have ceramic core radiators through the rest of the flat. I only use the 1 in my bedroom from 7am to 11am each morning! That’s my total heating usage. I have two electric showers, on 1 of which is used every other day (due to higher electricity bills) The bath is never used, I do use the hand wash basin, for washing myself on the day I do not use the shower) also for washing hands after toileting! I live on my own, I am 70 and vulnerable due to Severe COPD, Macular Degeneration in both of my eyes. I am in debt management, mainly due to cost of electricity and also being advised to change my heating 41/2 times as only change the loung as that’s all the eco scheme allowed. I have lived in my property for 21 years come July 2022. I have had highe electricity from the beginning 2001. When I first moved in, my husband was alive, he dies in 2004. Our electrify bills were very high, and with a lot of researching found that the builder/owner were connected to our meter. The builder were building a new block of apartments which were joined to our block. After my husband died,?it became clear that my bills were still extortionate, prior to my husband passing, I had nothing to do with any of the bills, he took care of everything. I have had two electrical surveys done costing me a fortune, but they could not find any other connected to our meter. It did come to light that the power into our apartment would never be enough if I put all my heaters on. This also came to light as when I tried to put 2 heaters on in my two spare rooms it blew the whole electrics, which had to be repaired from outside. ( yes all this was reported to the landowner/builder). He was not at interested. I could not afford to take him to court and could not get any help from anyone, not even CAB. I’m desperate for someone to help me sort these problems out! I am thinking that the flats that are joined to our block may be the problem. Please can you help me? This is really affecting my mental health, as I do not get anywhere when raising it with the electricity companies I have used.
