Energy is a business essential relied upon by companies across Britain to keep the lights on, computers running and power machinery. And that’s just the beginning; as we transition to a greener future, electricity supplies will keep properties warm with heat pumps and power cars using EV charging.
In summary, having a business energy supplier you can trust is essential. We’ve prepared this guide to help answer the question – Which UK business energy supplier is best?
Here are the categories we’ve considered:
With over 80 business energy suppliers competing for new customers, it can be difficult to single out the ‘best’ commercial energy suppliers.
However, there are a few different ways of ranking business energy suppliers. Let’s start with a brief summary of the nine biggest business energy suppliers according to Ofgem’s market indicators data.
EDF Energy is one of the largest energy suppliers to businesses and is Britain’s biggest zero-carbon electricity generator. It is currently building two new-generation nuclear reactors at Hinkley Point C that will significantly reduce the country’s overall carbon emissions.
EDF provides 24/7 live chat support for its customers and offers a wide choice of deals to small and large business properties.
EON Energy is another member of the ‘big six’ energy suppliers. EON energy works with both its business and domestic customers to reduce their carbon footprint by implementing smart technologies.
EON Energy has recently acquired the business energy supplier arm of nPower. The combined EON and nPower businesses are now one of the largest commercial energy suppliers in the UK.
SSE’s Business Energy division is one of the largest in the commercial market. SSE energy solutions currently supplies over half a million business energy meters across the UK.
SSE’s business emergy supplies are sourced from SSE’s own wind and hydro generation plants. SSE was a principal partner of the UK government in the Glasgow COP 26 climate change conference.
British Gas is the largest supplier of energy services to homes in the UK and forms a significant part of the British business energy market. British Gas is owned by Centrica, a London Stock Exchange-listed multinational energy firm.
British Gas supplies Energy to over 350,000 organisations across the country, providing a full suite of additional services such as new connections, renewable energy generation, EV charging points and boiler maintenance.
Drax is the new name for Haven Power; Drax helps businesses cut costs and reduce energy through 100% renewable sourced power. Drax’s works to support businesses that generate their own renewable power to sell back to the national grid.
Drax operates its commercial supply business under the Opus Energy brand, specialising in providing energy to small and medium-sized organisations. The business energy supply of Opus Energy is 100% renewable.
Scottish Power is an energy company based in Glasgow, a subsidiary of the Spanish utility giant Iberola. Scottish Power has various roles in the UK energy industry as a distribution network operator, transmission owner and supplier to homes and businesses.
Scottish Power offers energy supplies to businesses, small and large, with various deals to suit all needs. Scottish Power provides 100% renewable deals supplied by Scottish Power’s own wind turbine generators.
Opus Energy is a leading UK business energy supplier supplying over 200,000 customers with electricity across the country.
Opus Energy is a subsidiary of Drax that services energy to small and medium-sized businesses. Drax is an energy giant that operates the world’s largest biomass power station.
Engie is committed to assisting SMEs to transition to low-carbon operations by providing a clean, affordable energy supply.
Engie also offers competitive purchase agreements through the Smart Export Guarantee scheme for businesses that generate their electricity.
Like British Gas, Total also claims to be the biggest supplier of energy products to UK businesses.
Total Energies is focused on becoming the UK’s most trusted business energy supplier providing its customers with a secure, hassle-free power supply.
The best business energy supplier isn’t a straightforward question, as it depends on your company’s particular circumstances. We’ve covered the biggest business energy suppliers in the section above, but these are not necessarily the ones to choose.
Our in-house business energy experts have ranked business energy suppliers into a few different categories:
According to Trustpilot, here are the three top-ranked business energy suppliers using verified customer reviews:

It’s worth noting that a large portion of the thousands of reviews Octopus Energy receives come from their domestic customers. Still, there is a general consensus that Octopus Energy provides a fantastic service.
Most business energy suppliers now offer a green electricity product which supplies electricity from renewable sources like wind and solar. Power generation in the UK is increasingly sourced from green sources, making renewable electricity affordable for most businesses.
It’s difficult to single out a business electricity supplier for being the greenest. However, we’ll use this as an opportunity to highlight an innovative supplier: Good Energy.
Unlike other business energy suppliers, Good Energy generates the electricity it supplies from 1,700 independent generators, buying directly from small renewable sources, including businesses that generate their own renewable electricity.
Business energy suppliers for small businesses work slightly differently than for larger companies. For example, business energy suppliers must put contract end and notice dates on all bills and cannot enforce back-billing over 12 months.
Some business energy suppliers specifically focus on providing an excellent service to smaller customers, including tools like:
Three brands in particular, Opus Energy, E.ON Next and British Gas Lite, are renowned for their strong proposition for smaller businesses.
Unfortunately, there’s no straight answer to which business energy supplier is the cheapest. All business energy suppliers change prices daily with market changes and target specific customer groups.
Business energy supplier quotes are affected by factors such as:

In this guide, we explore all you need to know about business energy suppliers, from what they actually do to which ones have recently gone bust.
A “business energy supplier” is a retail supplier of energy used by commercial properties.
The energy market is complicated, with many different companies generating, transporting and selling energy. However, the role of a business energy supplier is actually quite simple.
A business energy supplier provides a supply of energy to non-domestic properties. Here’s how business energy suppliers provide electricity to commercial properties:
First, the supplier will purchase electricity on the national grid from:
The business energy supplier then pays to move the electricity through the local electricity distribution network to your business property. An energy meter at your property measures your business energy usage.
Your business energy supplier will bill you for the electricity your property uses based on rates agreed in your business energy tariff.
The last quarter of 2021 and the start of 2022 were difficult for business energy suppliers. The wholesale cost of natural gas has increased by 250%, resulting in several corporate failures in suppliers.
Here’s the list of business energy suppliers that have gone out of business in the last year:
Business energy supplier | Date | Number of customers |
---|---|---|
Whoop Energy | 18 February 2022 | 212 |
Xcel Power Ltd | 18 February 2022 | 274 |
Together Energy Retail Ltd | 18 January 2022 | 1 |
CNG Energy | 3 November 2021 | 41000 |
MA Energy | 2 November 2021 | 300 |
Ampoweruk | 2 November 2021 | 2000 |
Bluegreen Energy | 1 November 2021 | 5900 |
Daligas | 14 October 2021 | 9000 |
Symbio Energy | 29 September 2021 | 48000 |
People's Energy | 14 September 2021 | 1000 |
PFP Energy | 7 September 2021 | 5600 |
Hub Energy | 9 August 2021 | 9000 |
Ofgem, the energy industry regulator, has issued the following advice to customers of business energy suppliers that have gone out of business:
In the case of a corporate failure of a licenced business energy supplier, Ofgem will step in and ensure there will be no disruption to your supply of energy.
In a supplier failure, Ofgem appoints a supplier of last resort. All customer accounts of the bankrupt supplier will transfer to the supplier of last resort. Once the appointment process is completed, your new business energy supplier will contact you.
You’ll receive communications from your new business energy supplier when the transfer has been completed. You’ll be supplied with energy from the transfer point under a deemed contract.
Under a deemed contract, you’ll pay expensive, variable out-of-contract rates, but you can switch to another supplier anytime.
Once your supplier of last resort transfer has been confirmed, we recommend using the AquaSwitch business electricity comparison or business gas comparison service to ensure your new supplier offers competitive prices.
A special administration process is where Ofgem provides funding and takes control of a bankrupt business energy supplier to ensure the supplier can continue to operate. The special administrator powers are used by Ofgem when larger suppliers go out of business.
On 22 November 2022, Bulb, the UK’s seventh-largest business energy supplier, announced it was insolvent. Since Bulb had too many customers to easily transfer to another supplier, Ofgem appointed a special administrator.
The special administrator will continue to run Bulb as usual, with its customers continuing to be supplied under their agreed business energy tariffs.
Following the special administration process, Octopus Energy announced that it would acquire Bulb. If you’re a Bulb business customer, you don’t need to take any action; the transfer of your supply and any balance you have will occur automatically.
Business energy suppliers must provide a customer services department to handle problems and customer complaints. If you have a complaint, the first step is always to call your supplier and explain the problem and how you would like this to be resolved.
You can find the contact number of the customer services departments of your supplier in our guide above.
If you don’t feel your complaint has been appropriately resolved, you can formalise your complaint using a letter. The Citizens Advice Bureau have published a handy template you can use to prepare your letter. We recommend including any supporting evidence, such as photos, to support your formal complaint.
Ofgem sets out a further and final step. If you reach eight weeks of dialogue with your business energy supplier without resolution, you can escalate your complaint to the Energy Ombudsman. See contact details below:
Energy Ombudsman:
Contact number: 0330 440 1624.

Historically, the commercial energy market has been dominated by the Big Six suppliers. In the nineties, the government gradually relaxed the requirements for new market entrants to enhance competition.
The 2010s saw a boom in challengers entering the market to compete against the Big Six. Some suppliers have gained a huge market share from a tech-led approach; in particular, Octopus and Ovo are tremendous success stories.
In the last few years, business energy suppliers have been hit by the twin effects of COVID-19 and soaring wholesale energy costs. The financial pressure of these events has resulted in a high volume of smaller energy suppliers going out of business. Through the supplier of last resort process, the market for business energy suppliers has gradually consolidated.
Here are the most commonly asked questions surrounding business energy suppliers.
Here are the top ten business energy suppliers based on the number of registered non-domestic supply points:
The data was accurate as of Q4 2021, as Ofgem hasn’t yet published an updated data set.
The cheapest supplier will constantly vary as the “Big Six” compete.
Each will adjust their tariffs according to the niche they want to dominate, which means tariffs will vary per usage, location, tariff type, contract length and the market’s current state.
All the suppliers quote differently for different situations and generally update their prices daily, so there is no straightforward answer to which big six business energy supplier is the cheapest.
We recommend using our business energy comparison tool to compare the latest business energy tariffs and get rates tailored to your business and property.
Energy costs for large businesses can be enormous, and deals offered in the market are complex. See our guide to energy for large companies.
Yes, Octopus Energy does offer the best business energy rates for companies in the UK. Octopus offers a range of business energy contracts; before committing, we recommend you shop around.
Use our business energy comparison service to compare the latest business energy deals and ensure you make the right decision – you can compare business electricity and business gas suppliers individually.
This ultimately depends on what works best for you. Are you looking for the cheapest business energy supplier or a multi-site business looking for 24-hour customer service and consolidated billing?
If improved customer service is your priority, you should search for business energy supplier reviews and judge based on what other customers say.
However, if it’s the cost of business energy you want to improve on, our business energy comparison service will help you determine the best energy prices for your business.
Here is a list of the business energy suppliers that offer green energy tariffs:
No. Switching business energy suppliers requires no change in how energy is delivered to your business property.
Your new business energy supplier will continue to use the same pipes, wires and meters used by your current supplier.
The process of switching business energy suppliers is essentially a paperwork exercise. Switching from one supplier to another will never result in physical disconnection or interruption of energy supplies.
EDF could be the cheapest business energy supplier. However, it depends entirely on your location, usage as well as the current state of the market.
We advise you to compare the latest business energy prices and then make an informed decision. If it’s low-cost energy you are looking for, compare the latest deals out there and switch to the cheapest.
Here’s how to compare business energy with ease.
Some business energy suppliers are also domestic energy suppliers, but there are some key differences between the two services:
The switching process for business energy suppliers in the UK can take anywhere from 4-6 weeks, but it’s important to remember that this can vary depending on certain factors.
To ensure a smooth and timely switch, it’s a good idea to start the process well before your current contract end date and work closely with your new business energy supplier to provide any additional information they need.
Factors that affect the time it takes to switch business energy providers are:
To ensure a smooth switching process, starting the process well before your contract end date is a good idea. Work closely with your new supplier to provide any needed information or support.
Read our guide on switching business energy suppliers.
The best way to switch business energy suppliers for multiple properties depends on your current situation; here we explore these:
For option 1:
Firstly, you will want to assess each site’s current energy consumption, business energy tariff and contract end date. The contract end date of each property is important as most suppliers will only allow you to quote six months in advance of the contract end date.
Once you have collated this information, you can compare the different tariffs. We recommend that you go directly to multiple business energy suppliers and get them to tender for your portfolio of sites. Or, you can use a trusted business comparison site to compare the different deals.
We recommend asking your suppliers to arrange your contract, so all your supply points have a common end date (making managing your contract much easier).
By going to multiple business energy suppliers, you can compare the different options available to you. It’s important to compare each supplier’s rates, the annual total contract cost, the strength of their customer service, and any add-ons they can provide.
Our business experts can help collect quotes for your property portfolio, simply enter your details and select “multiple properties”.
Once you’ve agreed on a new contract:
Option 2:
You are already in a good position. Having all your properties consolidated into one contract is much easier to manage. You will want to contact your current supplier, ask for a renewal quote, and see if you are happy with their pricing and service.
Ask yourself the reason for switching to a new supplier; if it’s the price – reach out to some of the most trusted business energy suppliers and request a tender for your sites.
If it’s due to poor customer service, review a selection of the trusted suppliers feedback from current and former customers. This way, you can ensure you are happy with their service.
If you are happy with your current supplier, contact their renewal team and discuss a new contract with them.
Use our business energy comparison service to collect quotes for your portfolio of properties in the final year of your current contract.
Here is a summary of the key benefits of using a broker to find your new business energy supplier.
Here are the key benefits of choosing a green business energy supplier:
For more information, check out our complete guide on green energy benefits. The price of green energy is falling as more and more wind and solar farms are added to the British electricity grid.
It depends; if you’ve agreed to a contract with your current business energy supplier, it will not usually be possible to negotiate rates before your contract end date.
However, if you’re out-of-contract paying standard variable rates, then it is certainly possible. Out-of-contract business energy rates are typically needlessly expensive, and your supplier may offer a cheaper fixed tariff as an alternative.
To get the best business electricity rates, it’s important to negotiate with your current supplier and compare the whole market. Collect quotes for your business today with the AquaSwitch business electricity comparison service.
Business energy suppliers and distributors perform very different roles in the energy market.
An electricity distributor owns and operates the local electricity distribution network, consisting of powerlines, underground cables and substations. The function of a distributor is to transport electricity from the core National Grid to homes and businesses in their local area.
In contrast, a business energy supplier will purchase electricity in the wholesale market and then pay the distributor to transport the energy to the commercial customers they supply.
The following table lists all Ofgem licensed business energy suppliers, updated quarterly by our in-house business energy experts. The list provides a link to the website of each business energy supplier or lets you know their current status if they are not currently accepting customers.
