What is average business energy consumption?
October 26th 2023
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 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 all year, which means rates can vary quite significantly. For a closer look at why energy prices are currently so volatile, check out our blog What's going on with energy prices? And to find out more about how the government is helping business owners deal with soaring energy costs, read our guide to the Energy Bills Discount Scheme.
Now let's back to looking into how much energy your business uses, 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 of which can affect the amount of energy they use.
Even just having different opening times and employees with different energy usage habits can all have an impact on energy usage.
Energy usage is measured in kilowatt-hours (kWh) and to give you an idea of how much energy a business like yours should be using, the number crunchers at Bionic have pulled together the following data on average kwh usage for small business and medium businesses.
What is the average energy usage for a microbusiness?
The average annual energy usage for a microbusiness is:
- Gas - between 5,000 kWh and 15,000 kWh
- Electricity - between 5,000 kWh and 15,000 kWh
What is the average energy usage for a small business?
The average annual energy usage for a small business is:
- Gas - between 15,000 kWh and 30,000 kWh
- Electricity - between 15,000 kWh and 25,000 kWh
What is the average energy usage for a medium-sized business?
The average annual energy usage for a medium-sized business is:
- Gas - between 30,000 kWh and 65,000 kWh
- Electricity - between 25,000 kWh and 50,000 kWh
What is the average energy usage for a large business?
The average annual energy usage for a large business is:
- Gas - more than 65,000 kWh
- Electricity - more than 50,000 kWh
These figures should only be used as a guide and the amount of energy your business uses will depend upon the industry you work in and how you use gas and electricity. We've broken down the figures in the tables below for easy reference.
What is the average gas consumption for UK businesses?
Knowing how much energy other businesses your size use is a good way to understand if your business is using too much. As with business electricity, your business gas usage will vary depending on the size of your business and how you power it.
The table below shows the average business gas usage, ordered by business size.
| Business Size | Low-end usage (kWh) | High-end usage (kWh) |
| Micro Business | 5,000 | 15,000 |
| Small business | 15,000 | 30,000 |
| Medium business | 30,000 | 65,000 |
| Large business | More than 65,000 kWh |
What is the average electricity consumption for UK businesses?
To give you an idea of how much electricity your business should be using, here are the average business electric consumption figures by business size and demand.
| Business Size | Low-end usage (kWh) | High-end usage (kWh) |
| Micro Business | 5,000 | 15,000 |
| Small business | 15,000 | 25,000 |
| Medium business | 25,000 | 50,000 |
| Large business | More than 55,000 kWh |
If your business uses more than 100,000 kWh of electricity a year, suppliers will class you as a large business and handle your supply differently. To find out more, check out our guide to large business energy and give our tech-enabled energy experts a call on 0800 077 3701.
What is an average business energy bill?
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 or not you use any 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 are 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 is an average business gas bill?
To give you an idea of how much you should be paying on business gas, here are the average business gas bills by business size.

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 definitely be overpaying for energy. If you’re in this position, it can help to compare the rates 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.
| Business type | Unit rate (per kWh) | Standing charge (daily) | Cost per year |
| Coffee Shop | 13.42p | 26.70p | £2,109 |
| Hair Salon | 13.88p | 27.23p | £2,182 |
| Small Farm | 14.19p | 24.21p | £2,218 |
| Dental Surgery | 13.84p | 27.61p | £2,176 |
| Restaurant | 14.87p | 25.46p | £3,067 |
| Newsagent | 14.51p | 24.28p | £1,830 |
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.

How to cut your business energy usage
Managing and improving the energy efficiency of your business will help to reduce the amount of energy consumed. There are any number of ways to do this, such as:
- Carrying out an energy audit
- Using energy-efficient lighting
- Using energy-efficient computers
- Encouraging your staff to go green
- Installing energy generation technology
Although the effectiveness of any energy efficiency measures depends on the type of business you run and the steps you take, even making a few small changes can help to make a big difference.
How to reduce your business energy bills
Cutting the amount of gas and electricity you use is obviously the most effective way to cut your business energy bills, but arguably the quickest and simplest way best to lower your bills is to switch to a cheaper tariff.
The tech-enabled energy experts at Bionic can find the right deal for your business in a matter of minutes and help you with the switch. To start your business energy comparison, let us know your postcode or give us a call on 0800 077 3701 and we’ll do the rest.
If you don’t arrange a new deal before your current one expires, your supplier will place you on its more expensive rates. The only way to make sure that you never pay more than you need to for energy is to stay on top of your renewal dates and switch at the right time.
