The electricity rate per kWh varies between businesses. Different suppliers may also set different rates. Larger businesses purchasing more energy will have more buying power. This allows them to negotiate lower unit prices.

Lower prices tend to be more available to companies that consume 100,000 kWh or more per year. We recommend using your business’ most recent yearly consumption data when comparing prices.

Gas Prices For Different Business Sizes 

The unit rate prices for business gas are much lower than those for electricity. SMEs can pay between 7.60p/kWh to 4.37p/kWh but may face a higher standing charge up to 70p per day.

What Are The Typical KWh Prices For Different Industries?

The type of industry your business operates in will impact consumption. This translates to higher rates per kWh.

Here are some examples of prices for different types of businesses:

Business Type

What Does kWh Mean?

 Kilowatt hour (kWh) is a unit used to measure the amount of electricity consumed. Energy companies use this unit to calculate your energy bills.

1 kWh is equivalent to using a computer for 3 hours or boiling the kettle 10 times.

What Other Costs May Be Included In My Business Electricity Bill?

There are a few other factors that make up your business electricity bill. These include:

  • Standing charge. This is a daily fee for the supply of energy to your business. Tariffs with no standing charge are available, however, these often have higher unit rate costs.
  • VAT. Businesses are required to pay 20% VAT on their energy bills.
  • Climate Change Levy (CCL). This is a tax for electricity generators not using renewable energy sources. Businesses with low energy consumption can be exempt from having to pay CCL. 

Understanding Your Electricity Bill

Here is what an energy efficient business looks like: 


Annual consumption (kWh)


Unit price per kWh


Daily standing charge


Total yearly bill (excluding CCL & VAT)






The business above would be charged £91.25 for the standing charge. (365 days * 0.25).  Their electricity usage is £2,100 (15,000 * 0.14). This gives a total bill of £2,191.25, excluding additional charges with VAT and Climate Change Levy (CCL).

What Are The Prices Per KWh For Wholesale Electricity?

Wholesale electricity prices can vary weekly or even daily. These prices have increased rapidly over recent months; in 2022 prices were around 19.19p per kWh.

In most cases, you’ll purchase your gas and electricity from suppliers such as Eon, Ovo or Shell. These retail prices tend to be double the cost of the electricity wholesale prices.

You should shop around and compare business electricity deals. Using a price comparison engine will help you find the cheapest tariffs. Bear in mind that tariffs with lower unit rates usually have a higher priced standing charge.

What Affects The Market Price Of Electricity?

 Your business electricity rates will be impacted by market activity. These factors are:

  • Demand. A rise in demand can lead to an increase in wholesale electricity costs. As this will cause generators to fund the additional output.

  • Weather. The weather can cause an increase or decrease in the demand for electricity. People will use lighting and heating more in cold and dark weather. On the flip side, high winds can help with wind turbine energy generation.
  • Commodities. The cost of the commodities that create electricity has a significant impact on market costs. The main commodities being fossil fuels such as gas, coal and oil.
  • Carbon Cost. Generators powered by fossil fuels are required to purchase a certificate for each tonne of CO2 created. This serves as a penalty for not using renewable sources such as solar, wind or combined heat and power. This expense can have an impact on electricity prices.
  • Delivery Constraints. Any outages, maintenance or connection issues can affect electricity market costs.

What Factors Impact My Business Electricity Costs?

 Certain factors that are specific to your business will impact electricity prices. These include:

  • Consumption. The more electricity your business consumes, the higher your bill will be.
  • Business region. Different regions within the UK have different prices. This is known as the ‘energy postcode lottery.’
  • The size of your business. Larger businesses have more buying power. They may be offered cheaper rates through group buying schemes.
  • Your energy provider. Different energy suppliers offer different rates. Some will be cheaper than others. Switching suppliers can help you find a cheaper deal.
  • Your energy tariff. Your chosen energy tariff should be suitable for your business’ needs. An unsuitable tariff can lead to high bills.
