What is the average energy consumption for different UK businesses?

*Updated June 17, 2024

Although most businesses use between 15,000 and 25,000 kWh of energy a year, the average usage and cost of energy will differ depending on the size of the business, industry and how it uses energy.

In short, the larger the business, the more energy it’s likely to use.

Energy prices have been unusually volatile over the last few years, which has caused huge differences in the rates suppliers quoted. Prices began to drop steadily from December 2022 and levelled off across 2023.  

Although rates are no longer as volatile (and are now closer to what they were towards the end of 2021) prices do seem to be rising again. For a closer look at why energy prices are changing, check out our guide - what's going on with energy prices?  

Now let's look at how much energy your businesses like yours use, the rates you can expect to pay, and some ways to cut costs.  

How much energy does an average business use?

All businesses have different energy demands - even if two businesses seem identical on the face of things, they’ll operate from different premises, which will have different heating, lighting and energy efficiency systems in place. All these things can affect the amount of energy they use. 

Even having different opening times and employees with different energy usage habits can impact energy usage. 

Figures from Ofgem show that around two-thirds of micro business owners don’t know how much gas (70%) or electricity (64%) they use each year. If this sounds like you, here are some average figures to give you an idea of roughly how much you can expect to use:

• Microbusinesses use an average of 10,000 kWh of gas and up to 15,000 kWh of electricity a year
• Small businesses use an average of 25,000 kWh of gas and up to 25,000 kWh of electricity a year
• Medium-sized businesses use an average of 45,000 kWh of gas and up to 50,000 kWh of electricity a year
• Large businesses use more than 65,000 kWh of gas and more than 50,000kWh of electricity a year

What makes up an average commercial energy bill?

Energy usage is measured in units of kilowatt-hours (kWh). Your energy bills will vary depending on how much gas and electricity you use at your business premises. 

The cost of your bills will also be affected by the type of tariff you're on, and although your business energy bill is made up of a number of costs, including VAT and government levies, there are two figures you need to look out for: 

• Unit cost - Measured in kilowatt-hours (kWh), this is the amount you pay for each unit of gas or electricity you use.
• Standing charge - This is a flat daily rate to cover the cost of getting the energy to your property and is charged regardless of whether you use gas or electricity.

If you’re looking to cut the cost of your bills, you’ll want a tariff that offers a lower unit rate and lower standing charge than the one you’re currently on, but you might be able to lower your bills by cutting the cost of just one of these charges.

The type of deal you’re on will also affect the cost of your business energy bills, and while there is a range of commercial tariffs on offer, simply choosing between a fixed rate and variable rate tariff can make a significant difference.

If you're on a variable-rate energy deal, the unit cost will fluctuate depending upon the current market cost of energy - if prices go up, so do your energy bills, even if you consistently use the same amount of gas and electricity each month.

If you sign up for a fixed-rate deal, this means the unit rate is fixed and you’ll pay a flat rate for each unit of energy you use. Fixed-rate deals offer an effective way to protect against price hikes if energy rates increase, and can also make budgeting a bit easier, but your bills will still fluctuate according to your usage.

What are the average business electricity rates by business type?

If you’ve never switched business electricity, you’ll not be on your supplier’s most competitive rates and will be overpaying for energy. This is when it can help to compare what you’re currently paying with the average rates paid by other businesses in your sector. 

If, for instance, you run a restaurant, asking how much energy an average restaurant uses every year and comparing the costs with the rates you pay will instantly highlight how much you could save by switching suppliers.

Please note that the above rates are pre-energy crisis and pre-Ukraine conflict. Prices are currently so volatile that it's impossible to quote average prices.
