What to look for when you compare business energy
When comparing business energy suppliers, the key factors to consider are the quoted price and the best business energy supplier reviews.
Here are a few other factors that you’ll want to consider when comparing business energy suppliers:
Fixed or flexible rates
Understand whether you are committing to receiving energy at a fixed or variable rate per kWh. In a variable tariff, your price may go up or down as market conditions change.
The contract term
The typical fixed-rate energy tariff lasts between 1 and 3 years. During this period you’ll receive energy at the agreed rate unless you move out of the property.
Standing charge
Most commercial energy contracts come with a business energy standing charge that you’ll pay each day of the contract, regardless of whether your business uses any energy.
Payment method
Most suppliers require small businesses to settle monthly energy bills using direct debit. If your business needs more flexibility, it’s important to agree on this upfront.
Energy fuel mix
In renewable business energy, your supplier will commit to using only green energy sources such as wind and solar. Standard tariffs will use a mix of sources, including fossil fuels.
Renewal
All business energy contracts specify what will happen at the end of the fixed term if no new arrangements are made. Usually, it’s a rollover fixed tariff or a standard variable tariff.

Government support and business energy comparison
In response to the energy crisis, the government introduced two schemes to support UK businesses:
- Energy Bill Relief Scheme (October 2022 to March 2023) – Generous unlimited automatic discount scheme to cap business energy bills.
- Energy Bill Discount Scheme (April 2023 to March 2024) – A smaller discount of 2p per kWh for electricity and 0.7p per kWh for gas, applicable to the most expensive tariffs.
💡Both government support schemes have now concluded and have not been extended.
With the absence of government support, securing competitive energy rates from the market has become crucial.

Factors that affect business energy costs
Understanding what influences your business energy costs can help you make better decisions when you compare business energy; here’s what to consider when you compare business energy:
- Business size – Larger businesses often use more energy but can negotiate better rates due to higher consumption. Smaller businesses pay slightly more per unit as they don’t use enough energy to access bulk discounts.
- Energy usage – The more electricity and gas your business consumes, the higher the overall cost. Some tariffs also charge extra for using energy during peak hours, which can add to your bills if your business operates at busy times.
- Energy efficiency – Businesses that invest in energy-saving measures, like LED lighting, smart meters, and better insulation, can lower their consumption and reduce costs over time.
- Location – Energy prices vary by region due to distribution costs and supplier competition. Businesses in certain areas may pay more due to higher network charges.
- Tariff type – Fixed-rate tariffs provide price stability, protecting you from market fluctuations, while variable-rate tariffs change with wholesale energy prices, which could save money or increase costs.
- Contract length – Longer contracts often offer lower rates, but they can tie you into a fixed deal that may not remain competitive if energy prices drop. Shorter contracts provide flexibility but may cost more per unit.

In this section, we address some frequently asked questions about our business energy comparison service.
- How does my company’s credit score affect comparing business energy quotes?
- Why do I need an LOA when comparing business energy?
- Will my business energy quote change?
- Can I cancel my business energy contract?
- If I compare business energy prices, can I switch immediately?
- How do I know when my business energy contract ends?
- How much can I save by comparing business energy prices?
How does my company’s credit score affect comparing business energy quotes?
Business energy suppliers carefully manage credit risk when onboarding new customers.
Suppliers use different approaches to assess the credit scores of new customers, and it’s common for them to adjust pricing to account for the credit risk associated with a contract.
Suppliers may require a security deposit or mandate bill settlement by direct debit to reduce their exposure to credit risk when onboarding new customers with a lower credit score.
Why do I need an LOA when comparing business energy?
When comparing business energy quotes with AquaSwitch, you’ll need to sign a Letter of Authority (LOA) to authorise our experts to negotiate the best energy rates and manage the switching process on your behalf.
You can use our business energy comparison tool to view the latest prices, but if you decide to proceed with one of our quotes, you will need to sign an LOA.
Will my business energy quote change?
Unfortunately, prices fluctuate due to the dynamic nature of the energy market. If you receive a business energy comparison report today and decide to proceed with a quote two days later, prices will likely have changed.
We recommend carefully reviewing your energy quotes on the day you receive them to ensure you can secure the rate our business energy experts have presented.
Can I cancel my business energy contract?
You may cancel a business energy contract immediately without incurring costly exit charges in the following scenarios:
- You have recently moved into a property and are paying deemed rates.
- You are relocating out of your commercial property (change in tenancy).
- Your current tariff has ended, and you have moved onto variable rates.
Check out our complete guide to cancelling a business energy contract for more information.
If I compare business energy prices, can I switch immediately?
You can only switch business energy to a new contract the day after your current contract’s end date.
It’s important to note that it may take up to 4 weeks for a new supplier to take over your supply. If your contract end date is less than four weeks away, you may end up on out-of-contract rates while awaiting the transfer of your supply.
There are some exceptions to this:
- You’ve just moved into new premises: It may take up to 6 weeks for your new contract to come into effect, as you will need to provide proof of the move-in date and ensure the previous supplier is informed that the former tenant is no longer occupying the premises. The previous supplier must process this as a change of tenancy, which can delay the switch.
- You are currently out of contract: If you are out of contract, we can request that the new or existing supplier start your contract with an ASAP start date. However, note that switching to a new supplier can still take up to 4 weeks to complete the transfer.
How do I know when my business energy contract ends?
If you check your recent business energy bill, it will usually state the end date of your current contract. If not, we recommend reviewing your original agreement or contacting your supplier’s customer service team.
Knowing when your business energy contract ends is essential. If you haven’t arranged a new contract, you’ll automatically start paying unnecessarily high deemed standard variable rates.
How much can I save by comparing business energy prices?
Our energy experts have helped businesses save thousands on energy rates by switching to the most competitive deals. If you haven’t switched suppliers in a while, you may be paying unnecessarily high business energy rates.
Regardless of your situation, with our business energy comparison service, we’ll quickly let you know how much you can save.
Our bespoke business energy comparison services
Our energy experts recognise that every business has unique needs. They have assisted businesses of all sizes, from small enterprises to large corporations, in finding better energy deals. Regardless of your business size, we always go the extra mile.
Here, we outline the bespoke approach we take to business energy comparison for different types of companies:
Energy comparison for large businesses
Energy comparisons for large businesses require bespoke quotes, which can take a little longer to arrange but address specific needs such as:
- Multi-site energy meters – Where more than one property is included within a business energy contract.
- Maximum demand charges – An additional charge levied by your local distribution network operator to guarantee an agreed capacity for your business energy connection.
- Half-hour meters – Business energy meters that record consumption every half an hour, facilitating multi-rate tariffs.
Despite the additional steps, our experts are dedicated to supporting you throughout the comparison process for large business energy.
Small business energy comparison
Business energy is a significant overhead for most small businesses, so reducing your unit rate by even the slightest margin will help you save money.
The regular Ofgem gives additional rights to smaller businesses to make it easier to compare business energy prices and avoid expensive deemed contracts.
For these businesses, a commercial energy supplier must:
- Show your contract end date and notice period on all bills.
- Allow you to submit a notice of termination at any time during your contract.
Business energy suppliers offer simple fixed tariffs for smaller businesses to help you quickly and easily reduce energy bills. For more information, check out our guide to small business energy.
Compare renewable business energy
Renewable energy for businesses is getting cheaper each year as green technologies improve. The additional cost of a green energy tariff is getting ever closer to the price of a standard business energy tariff.
A few of the biggest energy suppliers now provide renewable energy as standard in their small business tariffs.
Enter your details using our business energy price comparison tool to get the latest renewable energy prices. Our business energy experts will automatically collect quotes from green energy suppliers for you to compare.
