What to look for when you compare business energy

When comparing business energy suppliers, the most important factors are the overall quoted price and which has the best business energy supplier reviews.

However, here are a few other factors that you’ll want to consider when comparing business energy suppliers:

Fixed or flexible rates

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 contract term

The typical fixed-rate energy tariff will last between 1 and 3 years. This is the period where you’ll receive energy at the agreed rate unless you move out of the property.

Standing charge

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

Payment method

Most suppliers require small businesses to use a direct debit for settling monthly energy bills. If your business needs more flexibility than this, it’s important to agree on this upfront.

Energy fuel mix

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.



All business energy contracts will tell you what happens at the end of the fixed term if you don’t make other arrangements. 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.

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 contract termination at any time during your contract.

Business energy suppliers offer simple fixed tariffs for smaller businesses that can 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.

To get the latest renewable energy prices, enter your details in our business energy price comparison tool. Our business energy experts will automatically collect quotes from green energy suppliers for you to compare.

What is the average business energy bill?

Business energy bills vary wildly in size. Small hairdressers will pay a few hundred pounds monthly; an aluminium smelting plant will pay millions. The key point here is that businesses pay for each kWh of energy used, and these consumption charges make up the biggest part of business energy bills.

According to the most recent government statistics, the average business is paying between 27 and 30 pence per kWh on its energy bills. This average, however, disguises significant differences from one business to another. There are broadly three scenarios:

  • Businesses that agreed to fixed contracts in the second half of 2022 will be paying much higher than these rates and up to as high as 100p/kWh.
  • Businesses on older fixed contracts that pre-date the energy crisis could be paying as low as 11p/kWh.
  • Businesses on standard variable default rates will be paying unfavourable rates that could be as high as 40p/kWh. These can make significant savings by comparing business energy rates today.

Business energy comparison – FAQs

Here are frequently asked questions about energy comparison for business. We cover deemed contracts, cancelling business energy contracts and much more.

How does my company’s credit score affect comparing business energy quotes?

Business energy suppliers carefully manage credit risk when onboarding new customers. Suppliers have different approaches when it comes to assessing the credit scores of new customers. It’s common to adjust their pricing to factor in the credit risk associated with a contract.

To accept a new customer with a lower credit score, suppliers can ask for a security deposit or bill settlement by direct debit to reduce their exposure to credit risk.

Read our in-depth guide on credit scores and business energy comparison.

How much does business energy cost?

The cost of business energy tariffs available in the market changes daily and is affected by several different factors. Business energy costs are impacted by the following:

  • Wholesale cost of energy – The cost of generating energy or importing it into Britain.
  • Energy distribution costs – The cost involved in moving energy through the national grid to your property
  • Government taxes – The business energy bills include VAT and the climate change levy.

The cost of business energy also depends on your company’s energy consumption location.  Use the AquaSwitch business energy comparison tool to request quotes tailored to your business.

Why do commercial energy prices depend on the size of my business?

Typically, companies that consume more energy can access lower business energy prices.

Business energy suppliers can negotiate lower fixed wholesale rates on the energy market in high-consumption business energy contracts. It’s most easily thought of as a bulk-buy discount.

The following table shows the latest government statistics on the business energy rates paid by different sizes of companies.

For business energy supply:

Business sizeAnnual consumption (kWh)Unit electricity rate/kWh
Very small<20,00031.60
Small20,000 - 500,00033.95
Small/Medium500,000 to 2,000,00032.11
Medium2,000,000 to 20,000,00030.09

Please note that the government statistics are about six months out of date. For the latest business energy rates, see above.

Should I get a smart meter for my business energy consumption?

Yes, most businesses can benefit from upgrading to a smart meter, which offers the following advantages:

  • Accurate measurement of electricity usage to calculate business energy bills. Pay for exactly the energy you use.
  • Your energy supplier can identify if your business premises have suffered a power cut and resolve it immediately.
  • Be alerted to any energy consumption issues that arise.

For more information, read our guide on smart meters for business.

Why do I need an LOA when comparing business energy?

When you compare business energy quotes with AquaSwitch, you must sign an LOA to allow us to negotiate the best energy rates and manage the switching process on your behalf.

You can use our business energy comparison tool to compare the latest prices, but for AquaSwitch to manage the switch, an LOA must be completed.

Does my business need a half-hourly meter?

Half-hour business energy meters are compulsory for commercial properties with energy demands of over 100kW in any 30-minute period.

Check out our comprehensive guide to half-hourly business energy meters for more information.

Will my business energy quote change?

Unfortunately, prices fluctuate due to the ever-changing nature of the energy market. If you receive a business energy comparison report today and look to go ahead with a quote in two days, prices will likely have changed.

Once you use the business energy comparison tool, it’s worth reviewing each supplier’s prices and then deciding whether to proceed with those rates. The rates you get today will differ from tomorrow due to volatility in the wholesale energy market.

Can I cancel my business energy contract?

You can cancel a business energy contract immediately without incurring expensive exit charges in the following scenarios:

  • You’ve 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’ve moved on to variable rates.

For more information, check out our complete guide to cancelling a business energy contract.

Does the energy price cap apply to businesses?

Normally, business energy prices are not capped. Unlike domestic energy products, energy companies are not regulated with a price cap.

The lack of a business energy price cap means that business energy suppliers’ out-of-contract rates can be much higher than current market prices. This makes energy comparison for business an essential part of keeping costs down.

Check out our complete guide to the business energy price cap.

Who supplies my business energy?

Energy operators can tell you who currently supplies energy to your business property. To do this, use the Energy Network Association tool to help you find your business energy supplier using your postcode.

Once you find out who supplies your business energy, reach out to them, and they can give you your MPAN (Meter Point Administration Number) and MPRN (For Gas) as well.

MPAN and MPRN numbers will allow you to compare business energy prices by receiving quotes tailored to your energy supply points.

What is a multi-site meter?

A multi-site meter is an efficient way for your business to organise the billing for numerous energy supply points. This could be the billing for meters housed in one large business site or across multiple business locations.

Multi-site meters can save business owners money, time, and hassle. Trying to gather different meter reads for different suppliers around your multiple properties can be costly. It’s a huge benefit when you go to compare business energy prices.

If I compare business energy prices, can I switch immediately?

You can only switch to a new contract the day after your contract end date. It’s important to note that it can take up to 4 weeks for a new supplier to take over your supply, so if your contract end date is less than four weeks away, you may end up on out-of-contract rates while you wait for the transfer of your supply.

There are some exceptions to this.

  • You’ve just moved into new premises: It can 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 make sure the previous supplier is aware the old tenant is no longer in the premises. The old supplier will have to process this as a change of tenancy and can delay the switch.
  • You are currently out of contract: If you are currently out of contract, we can ask the new supplier or existing supplier to start your new contract with an ASAP start date. Please note that switching to a new supplier could take up to 4 weeks for the transfer process.

How do I know if my business is on a deemed contract or is paying out-of-contract rates?

Avoiding expensive out-of-contract business energy rates in a deemed contract is key to avoiding overpaying for business energy.

The most common indicators that you are paying for energy in a deemed contract are:

  • You’ve recently moved into a property but have not yet agreed to an energy contract.
  • You’ve noticed a significant increase in the unit rate on your energy bills.

Your business energy supplier must tell you exactly what kind of contract you are on and the cheaper alternatives that they offer. If you are uncertain about the current status of your business energy tariff, we recommend contacting the customer services department of your supplier.

How do I know when my business energy contract is coming to an end?

If you look at your recent business energy bill, it will usually state the end date of your current contract. If not, we recommend reviewing the original agreement that you signed or otherwise contacting the customer services of your business energy supplier.

It’s important to know when your business energy contract ends. If you haven’t arranged another business energy contract, you’ll automatically start paying needlessly expensive deemed standard variable energy rates.

It’s so important that we’ve published a complete guide on what happens at the end of a business energy contract.

Will my business energy renewal quote be cheaper?

Knowing whether your renewal quote will be cheaper than your current tariff is difficult. It depends on multiple factors. If you recently fixed for a year in the height of the business energy crisis, your current supplier may be able to fix you at a better rate for the future.

We recommend using our business energy comparison service to compare the latest prices and rates. You’ll quickly find out if your renewal quote is competitive.

How much can I save if I compare business energy prices?

AquaSwitch has helped businesses save thousands on energy rates by switching to the most competitive deals. If you haven’t switched suppliers in a while, you could be paying unnecessarily expensive business energy rates.

Regardless of your situation with our business energy comparison service we’ll quickly let you know how much you can save.

What’s the difference between business and domestic energy?

Business energy is essentially gas and electricity for commercial buildings. It’s similar to domestic energy supplies but with a few differences:

  • For businesses, you will be quoted separately for business gas prices and business electricity prices, unlike households, where you get dual-fuel tariffs.
  • Businesses pay 20% VAT on business energy bills compared to the 5% VAT homeowners pay.
  • The unit rates are generally lower for commercial compared to domestic, as the business energy supplier purchases the energy in bulk to negotiate lower rates.

Check out our full guide to the difference between domestic and business energy.
