How Much Does Business Electricity Cost In The UK?

In some countries, the rates are so high that these bills make their way to the account payables portion of the firms' balance sheet, while for others, this is not even a problem and is considered a low amount.

This also varies based on the size of the firm and what the firm does for a living. There are different business electricity rates in the UK, and these rates have been listed down below.

Business Electricity Rates for Micro Businesses

These businesses are extremely small in size. Sole traders mostly run a business like this. There are hardly any signs of partnerships. A micro business has hardly one or two employees, and their work is small.

Due to this, they do not require a lot of electricity, their bills are not spread over higher numbers of fixed units, and they cannot take advantage of economies of scale. These businesses are charged around 18.8 pence per kilowatt an hour.

Business Electricity Rates for Small Sized Businesses

Sole traders usually run these, but unlike micro-businesses, partnerships can be seen in this type of business. The number of employees is slightly higher. An example can be a small café or salon. The office size is slightly bigger than micro-businesses as well.

These types of businesses are charged higher than micro-businesses. Almost around 19 pence for every kilowatt an hour. They consume more energy because of the increased number of employees and office size. 

On average, a small-sized business uses around 20,000 plus kilowatts of energy an hour. They also experience a value-added tax of 20%.

Business Electricity Rates for Medium-Sized Businesses

The office size is bigger than the small-sized businesses, of course. These types of businesses have employees of fewer than 100 but greater than 30. They also tend to use a lot more electricity as well. However, the fun fact is that they charged lower than a small-sized business.

They are only charged around 17.5 pence per kilowatt an hour of energy consumed. This is mainly because the concept of economies of scale has begun. Bulk buying has become a benefit which they are now seeking due to its bigger size. The cost is spread over the high number of fixed units.

Business Electricity Rates for Large Sized Businesses

A large-sized business is hardly ever run by sole traders because of the high levels of expenses. These are usually formed under a partnership, or the company becomes a public company. 

The number of employees is greater than 100, and the office size is huge as well. A large-sized business also tends to use a lot more energy than other businesses of different sizes.

However, out of all the sizes, a large-sized business receives the lowest rates in the market, and that is because the cost is spread over more fixed units. They can enjoy bulk buying and economies of scale. These businesses are charged around 17 pence per kilowatt an hour of energy or electricity, in particular, being used.

When all is said and done, it is important to understand the factors that can affect the different rates of electricity being charged to a business in the UK. Some of these factors have been listed down below.

Using gas and electricity together:

If a company relies more on gas and less on electricity for different appliances, the charges would be a lot different in nature as well. Some companies are just more intensive towards one type of source of energy being supplied to them.

Tenure of contract:

If the contract is for a long period of time and the supplier wants to remain your partner in the long run, then you might be able to avail more discounts than if you had picked up and formed a short-term contract with your supplier.

Location of business:

If your office is located in a place or city in the UK where the overall rates of everything in the market are low, then you will be charged low rates for electricity as compared to had your office been in a posh area.

Prevailing prices of electricity:

Before making the contract, you must see what price is currently being offered in the market. This is because you need to make sure that you do not pay more than what you originally had to. This is important and must be covered in your market research process. Check the overall wholesale prices. If the price of gas is lower than electricity, you would want to switch the source of energy altogether.


The average rate being charged by suppliers for electricity is around 13.5 pence per kilowatt an hour. If your supplier is charging anything above that or anything above what your competitors are being charged, you might want to change the supplier altogether.

Value Added Tax:

Some people might argue that businesses tend to pay lower than residents or domestic consumers. However, the truth is that even though businesses are charged lower rates than residents and domestic consumers, they still have to pay the value-added tax. This tax is charged to all businesses of all sizes. 

Businesses have to give out 20 to 30 percent of the total bill that they have because that is what the government is seeking. 

The taxes being charged on the domestic consumers or residents stands in no comparison to this. They are only charged a mere 5% of tax when it comes to electricity bills. This is because the government provides more relief to residents and domestic consumers than businesses.

This was all about the different rates that are charged to businesses. We had understood that as the size of the businesses increases, the number of employees and size of the office also starts to increase. However, with that, their energy consumption patterns also get affected.

Moreover, as the size of a business increases, the tariff for electricity being charged over them tends to fall. So, we can say that an inverse relationship exists between the size of a business and the electricity rates. Moreover, before making any budgeting or cost decisions, it would be wise to consider all the factors listed above.
