Is there an energy price cap for business?

*Updated November 22, 2024.

There is no price cap on business energy, only on domestic energy. 

Unlike domestic energy customers, businesses get no government support with energy bills. Although the Energy Bill Relief Scheme and Energy Bills Discount Scheme were introduced to help businesses during the height of the energy price crisis, no further government support has been given since these schemes ended back in March.

There's more below on how the Energy Bill Relief Scheme worked and you can read more on The Energy Bills Discount Scheme, here.

What is the energy price cap?

The energy price cap sets the maximum price that energy suppliers can charge domestic customers on prepayment and standard variable tariffs. 

The cap is reviewed and set every three months Ofgem, the UK energy regulator. This is to factor in changes to wholesale energy prices, policy, network and operating costs, and prepayment meter costs.

Although usually described as the annual bill an average household on dual fuel tariff would pay, the cap is actually on the standing charge and unit rates. This means that household bills will be higher or lower than the advertised cap, depending on how much energy they use.

What is the current energy price cap level?

Until December 31, 2024, the energy price cap per unit and the standing charge will be:

• Electricity - 24.50 pence per kWh and 60.99 pence daily standing charge
• Gas - 6.24 pence per kWh and 31.66 pence daily standing charge

This means an average household on a standard variable tariff paying by Direct Debit can expect to pay £1,717 a year on gas and electricity. This is an increase of about 10% on the last cap level.

The price cap will increase again from January 1, 2025, as below:

• Electricity - 24.86 pence per kWh and 60.97 pence daily standing charge
• Gas - 6.34 pence per kWh and 31.65 pence daily standing charge

This means that same household will now pay £1,738 a year, an annual increase of about £21.

Increases in wholesale gas prices are thought to be the main reason for the increase. This is the price suppliers pay for the energy they provide to homes and businesses, and Ofgem figures show it increased by 29% between February and June this year. You can read more on this in our guide to business energy price rises.

And because of the way the energy market works, the price of gas directly affects the price of electricity, even though many suppliers use renewable sources. To understand more on this, check out our guide on how energy is bought and sold in the UK.

Although the price cap only affects domestic energy rates, an increase in the cap indicates that energy prices could increase for businesses too.

What is the business energy price cap?

There is no business energy price cap. The complexity of commercial energy contracts and the difference in usage between businesses means that a cap on business energy rates would be difficult to set up.  

Unlike households - where most use gas and electricity for the same things but at different levels - the difference in how and when businesses use energy can be huge. 

Although a fish and chip shop and a car mechanic both need electricity, how and when they use this power is completely different. This is why there are no ‘off-the-shelf’ options for businesses and contracts need to be tailored to meet individual needs.    

This makes it more difficult to create a single blanket rate across all businesses, so there is no commercial energy price cap. 

When the government did offer support, schemes were designed to reflect the complexity of commercial energy contracts. This meant financial support was offered to all sizes and types of businesses. 

Do we need a cap on energy rates? 

Wholesale energy prices have been so volatile in recent years that households and businesses across the UK have been hit with record energy bills. A price cap is one way to help lower the amount customers pay for energy. But it’s not perfect. 

The energy price cap was introduced in 2019 to limit how much supplies could charge households on credit meters for gas and electricity. This came two years after the Safeguard Tariff, which caps the unit rate suppliers can charge anyone paying for gas or electricity in advance using a prepayment meter. 

The cap was brought in to end what (then Prime Minister) Theresa May described as “rip-off energy prices” that were being charged as a result of Britain’s “broken energy market”. 

Although it does help to control prices, the problem with this system is that it causes prices to bunch around the level of the cap. When the cap was introduced, the number of cheap energy deals (those that cost less than £1,000 per year) dropped by 90% during 2018, falling from 77 at the start of the year to just eight by the end. 

This made the domestic market a lot less competitive. The price cap was even cited as one of several reasons why some energy suppliers went bust or stopped trading over the last few years.  

Should you fix your business energy rates? 

Although we can't predict what will happen to energy prices, fixing your rates is the only way to guarantee bill stability by locking in a consistent price for your energy and the current discount. 

That’s where the tech-enabled experts at Bionic can help. We’ll compare rates from a panel of trusted UK suppliers to get our best available fixed rates for your business.

What was the Energy Bill Relief Scheme? 

The Energy Bill Relief Scheme (EBRS) is now closed. The Energy Bill Relief Scheme was a discount on business energy bills that ran for six months between October 1, 2022, and March 31, 2023. EBRS worked differently from a price cap. Instead of capping rates, the government limited the wholesale price that suppliers pay to generators for energy. 

The savings made by suppliers were passed on to consumers by a cut in the wholesale cost part of the unit rate on all business energy contracts signed after December 1, 2021. The discount was also applied to businesses on flexible, out-of-contract, and deemed rates.

From the six months between October 1, 2022, and March 31, 2023, suppliers paid no more than £211 per megawatt hour (MWh – equal to 1,000 kWh) of electricity and no more than £75 per MWh for gas (or 21.1p per kWh of electricity and 7.5p per kWh of gas). This was known as the government baseline wholesale price.

For businesses on fixed-rate contracts, the discount was the difference between this baseline wholesale price and the rates agreed to when the energy contract was signed. Check out the government website to find out how much the discounts were worth.

If reference wholesale prices fell below this government-supported price, then rates were no longer discounted. This happened on December 26, 2022, meaning that any deals signed between then and January 16, 2023 (the latest data point we have) wouldn't have been eligible for a discount under the scheme. 

For out-of-contract, deemed, or any other variable rate contracts, the discount was the difference between the government baseline wholesale price and the relevant wholesale price charged by your supplier. But this discount was subject to a ‘maximum discount’ of 34.5p per kWh for electricity and 9.1p per kWh for gas.

The scheme also removed green levies from your rates, but the VAT on energy bills stayed the same.

Before we explain how it worked on different contracts with different rates, let's first look at the costs that make up your energy rates. To keep it simple, there are broadly two costs involved:

• Wholesale price - This is the amount suppliers pay for the energy they sell to you. This is the part that will be discounted.
• Other costs - This includes things like supplier margins, network costs, and green levies. The green levies will be removed as part of the scheme but the rest of the costs will remain unchanged. 

How did the Energy Bill Relief Scheme work on a fixed contract?

Here's how the discount could have worked for a business on a fixed electricity contract at an agreed rate of 60p per kWh.

How did the Energy Bill Relief Scheme work on out-of-contract rates?

Here's how the discount could have worked for a business on out-of-contract electricity rates of 130p per kWh.

^{*Please note, all figures are just illustrations of how the Energy Bill Relief Scheme could work, and not examples of the final legislation.}

*In this example, the discounted rate would have been 58.9p (the wholesale price of 80.0p minus the government baseline wholesale price of 21.1p). But this is higher than the maximum discount that is allowed under the scheme, so a discount of 34.5p is applied. 

This means that the higher your rates, the higher your bills will be, even once the discount has been applied. 

How did the Energy Bill Relief Scheme affect your business?  

The lower your contracted rates, the lower your discounted bills would have been during the scheme. 

The Energy Bill Relief Scheme limited the price that suppliers pay for wholesale electricity to 21p per kWh and 7.5p per kWh for gas. Your rate was then cut to this amount, subject to a ‘maximum discount’ of 34.5p per kWh for electricity and 9.1p per kWh for gas. 

The scheme was designed to give all businesses a discount on their energy bills for six months. But the size of this discount depended upon the rates you were paying and the type of contract you were on. 

• High out-of-contract rates - If you’re paying 130p per kWh for electricity and the wholesale costs account for 80p per kWh, your bill could be discounted to 90p per kWh. As in the example above, this is where the maximum discount comes into play. And it's worth noting that if wholesale prices go up, you’ll pay more. But if wholesale prices go down, you won’t necessarily pay less. 
• Medium fixed contract rates - If you pay 90p per kWh for electricity and the wholesale costs account for 60p per kWh, your bill could be discounted to 51p per kWh for the next six months. 
• Low fixed contract rates - If you pay 60p per kWh for electricity and the wholesale costs account for 40p per kWh, your bill could be discounted to 41p per kWh for the next six months. 

If you’re out of contract, suppliers can increase your rates at any time. This left businesses vulnerable to price increases, even while the scheme is running. 

This is why the government worked with energy suppliers to make sure all business customers in England, Scotland and Wales have the chance to switch to a fixed contract while the scheme is running.

How could the Energy Bill Relief Scheme have affected the business energy rates of a pub?

Let's say a pub signed a fixed contract in August 2022 and currently uses 4,000 kWh of electricity and 16,000 kWh of gas each month. Their contracted unit rates are currently 90p per kWh for electricity and 25p per kWh for gas. 

Here's how the discount will affect its rates for the next six months.

How could the Energy Bill Relief Scheme have affected the business energy rates of a school?

Here's how the discount will affect their rates for the next six months.

What businesses were eligible for the Energy Bill Relief Scheme? 

The Energy Bill Relief Scheme was applied to all non-domestic contracts. This means it was open to all businesses, including voluntary and public sector organisations. 

There were some exceptions, such as power stations, grid-level battery storage facilities, or any business that uses gas or electricity to generate power that will be sold back to the grid. 

The only other condition was that all eligible businesses are on one of the following contracts: 

• An existing fixed price contract that was agreed on or after December 1, 2021. This includes contracts signed while the scheme is running. 
• Deemed rates, out-of-contract rates, or a variable tariff 
• Flexible purchase or a similar contract

Energy price cap FAQs

If you're still not 100% sure what support is available to you or have more questions about the price cap, find out in our frequently asked questions. 

What is an energy price cap?

An energy price cap limits the amount that suppliers can charge for a unit of energy. It also usually caps the amount of the standing charge. Although price caps are often measured in the cost of an annual energy spend, this is just an average figure and you should always check the capped unit rate. 

The Energy Price Guarantee, for example, was often cited as capping household energy at £2,500 a year, but this figure is based on an average household paying by Direct Debit. The actual capped rates were 34.00p per unit of electricity rates at 10.30p per unit of gas rates at 10.30p per kWh. Standing charges were also capped at 46.35p for electricity and 28.49p for gas. This means that bills were higher or lower than the quoted £2,500 depending on energy usage and payment methods (paying by Direct Debit is usually the cheapest option). 

The government support schemes help businesses, but they are no energy price caps, like we see in domestic energy. Instead, the government are reducing the amount that suppliers have to pay for wholesale power and suppliers must pass this discount on to businesses, by law, as a discount on bills. 

Is there a small business energy price cap? 

There is no price cap on business energy rates, no matter the size of your business. Microbusinesses, small businesses and medium to large businesses don’t get the benefit of a price cap, unlike domestic contracts. There was a government discount in the form of discounted energy rates, but this ended on March 31, 2024.

How was the government discount applied?

The government provided a discount to your unit rates based on the difference between the wholesale cost and the “government-supported price” at the point of signing the contract. The credit was automatically applied to a bill each month. This scheme has now ended and no further government support has been announced.

Why am I paying more than 21.1p per kWh for electricity and 7.5p per kWh for gas?

This was not a price cap, it was a discount. Energy contract prices are made up of two main bits: 

1. The wholesale price, which is the amount the supplier has to pay generators for power
2. Charge and supplier profit

The government was reducing the amount that suppliers have to pay for wholesale power, down to 21.1p per kWh. This was discounted from the wholesale cost on your unit rate. You still need to pay the other elements that make up your bill.

If my business is in a fixed contract lower than the price cap, what happens?

Your contract will continue, and you'll pay your bills at the agreed contracted rates.

What happens if I can’t pay my business energy bills without support?

If you're struggling to pay your business energy bills, then you should contact your supplier as soon as possible. Under Ofgem rules, the supplier must offer a reasonably affordable payment plan. You can find out more in our guide to business energy bills.
