Business Energy Comparison Guide

Can you reduce your business energy costs by as much as 40% each year? If you have the time it is certainly worth comparing business energy prices. To benefit from the potential business cost savings we would advise that you compare a number of different business energy suppliers.

The current business electricity prices per kilowatt hour range from 20.31p for a small business. It is 17.52p per kWh for an industrial business. At the moment the average business gas price is 4.76p per kWh.

This business energy comparison guide will serve as a starting point to help you decide which UK business electricity and gas supplier to use. Business energy prices vary depending on where your business premises is, how long the contract is for, and the amount of electricity or gas that your business uses. We have looked at eight energy companies including the ‘Big Six’.

The Energy Bill Relief Scheme (EBRS)

Hopefully, you are already benefiting from the Energy Bill Relief Scheme. It should have been an automatic reduction that you should have noticed since the start of October 2022. It currently runs until the end of March 2022. If you haven’t received the discount please look into it as a matter of urgency. It is much the same as the domestic energy price cap.

Choosing the right business energy supplier

When it comes to choosing a business energy supplier, it’s important to do your research and find the right one for your company. It is also good to do it at a time when you do not have other pressing business matters. Hopefully, we can provide you with enough information on a selection of different energy suppliers. However, not all suppliers are created equal, and there are a few things you need to consider when making your decision.

The most important factor is price. Of course, it’s important to get a good deal on your energy, as it can be a high cost for any business. Also, it is crucial to consider the environmental impact and where your business energy will be sourced from. You also need to think about the quality of service offered by the supplier.

It’s also essential to make sure that the company you choose is reputable and has a good reputation. So make sure you read reviews and do your research before making a decision.

Ultimately, choosing the right business energy supplier is important for the success of your company. Take your time and do your research. You will be able to find the perfect supplier for your needs.

We have started by considering two options that are not in the Big Six. We then move on to the Big Six.

Opus Energy

Opus Energy is a relatively new business energy company that was established in 2001. They launched with the objective of using renewable sources to produce the electricity that they provide. Opus works exclusively in the business sector and currently provides over 225,000 customers with business energy.


Opus Energy offer both flexible and fixed tariffs. Both tariffs are considered to be competitively priced. They are called Opus Advance and Opus Advance Plus. The Opus Advance tariff is suitable for businesses of all sizes. Opus Advance is more suitable for larger businesses. Both tariffs use renewable energy to provide the business electricity. The main difference is that there is a small premium to be on the Advance Plus energy tariff. This is justified because all of the electricity is generated in the UK from its network of 2,100 renewable generators.


Using Opus can help your business with its renewable credentials. Customers of Opus Energy are allowed to use their digital certificates and social icons. It is a simple way to promote that you are using renewable energy to power your business.

For any business with solar, it could be good to know that you will earn back 15p / kWh for any electricity exported back to the grid.
