Questions and answers about EDF Energy for Large Business

We want to make it easier for you to get the answers to your questions

Below we have answered some of your most frequently asked questions. We have included helpful links to make it easier for you to manage your energy accounts

Understanding your Invoice

What is a consolidated bill and how can it help me?

If you are a customer with ten or more sites and you are happy to pay by Direct Debit each month, a consolidated bill could be great for you. Consolidated bills make it easy to keep on top of all your sites and simplify your admin because you can:

  • Group accounts together: by region, cost centre or any way you choose.
  • Choose your own unique reference numbers to manage your accounts easily.
  • Easily add or remove sites to your consolidated bill.

For more information on consolidated billing read our guide.

Why have I received an amended invoice?

We will send you an amended invoice when there has been a change that needs to be reflected on your invoice. Normally, this will happen when we have sent you an estimated bill and then receive a meter read from yourself or one of our meter readers, or when there has been a change to your contract terms.

If we are sending you an amended bill there are two ways we could revise your charges:

  • If we send you a credit note to cancel the original invoice in full, we will send you a new invoice for the charging period.
  • If we do not send a credit note to cancel the original invoice, we will add a single line adjustment on your next invoice. This adjustment will reflect an amendment made on your previous invoice. 

What does the balance brought forward value mean on my invoice?

If you have a payment outstanding on your previous invoice this amount will be shown on your latest invoice as the balance brought forward. Your invoice will also include the amount you owe for the current period and, at the top of your invoice, the outstanding balance on the account that you need to pay will be shown.

Understanding your Charges

What are fixed charges?

Fixed charges are listed individually on your bill and cover the costs associated with providing electricity to your site(s) e.g. providing cables and reading meters. These costs are charged regardless of how much electricity you use and help to maintain the energy network.

What are volume management charges?

Volume management charges are incurred if your use exceeds any volume tolerance levels agreed in your contract terms and conditions.

What are distribution charges?

Distribution charges are the cost of transporting electricity to your business. Electricity must travel from the transmission network through the local area distribution networks in order to get to you. These charges are made to us by your Distribution Network Operator and passed through on your invoice.

What are Reactive Power charges?

Reactive Power charges are passed through from your network operator for each supply point. They relate to power which has not been efficiently converted (wasted power) when operating certain types of equipment.

What are Transmission Network Use of System (TNUoS) charges?

TNUoS charges cover the maintenance and upgrade of high-voltage power lines that carry electricity from power stations to local distribution stations. These charges are based on forecasts and are subject to change throughout the year. Therefore, an annual reconciliation may be included on your invoice.

What are agent charges?

Agent charges are external charges that EDF Energy needs to levy onto your electricity supply charges if you don’t have a direct contract with the Meter Operator (MOP) or Data Collector (DC).

Further information about direct contracts with your Meter Operator/Data Collector can be found here.

We’ve put together a Monitor Report which gives you more information about all of your non-energy charges. Sign up to the Market Insight section of our website to view this.

Understanding VAT and CCL

What are VAT charges?

As a business your VAT rate will depend on whether your electricity supply is entirely for business use or for any non-business use, such as domestic or charitable. 

Do I qualify for a reduced VAT rate?

If your electricity supply is used wholly or partly for domestic or charitable non-business use, that part of the supply qualifies for the reduced rate of VAT. Additionally, VAT will be charged at a reduced rate if a site uses an average of less than 33 kWh per day. This is known as the “de minimis” rule.    

If you are a customer with qualifying use you are required to submit a separate Customer Declaration Certificate for each supply to tell us what percentage of your use is for domestic or charitable non-business use.

What is Climate Change Levy (CCL)?

CCL is a government tax on your business’ energy consumption. This tax aims to encourage greater energy efficiency and reduces gas emissions, helping to preserve our environment for the future. 

Do I qualify for CCL exemption?

If your electricity supply is used solely for business or non-domestic purposes you will pay the standard rate of VAT (20%) and CCL. If you are a business who pays a reduced rate of VAT (5%) or you use an average of less than 33 kWh per day, you don't pay the CCL.


Further information regarding VAT or CCL is available from HMRC.

Making a Payment

How can paying by Direct Debit help me?

Paying bills takes time, and time costs money. A Direct Debit saves you both by:

  • Reducing your workload through less admin with no cheques to write, and no posting.
  • Avoiding late payment interest charges because your bills are always paid on time.

To switch to direct debit all you need to do is fill out an application.

How can I pay by BACS or CHAPS?

To pay your bills using either the Bankers Automated Clearing System (BACS) or Clearing House Automated Payment System (CHAPS), you will need to arrange the payment with your bank and give them these details:

  • Our bank account details, which are on the back of your bill
  • Your account number, which is on the front of your bill.

Please remember that BACS payments take 3–4 working days to clear into our bank account. CHAPS payments clear the same day, with an admin fee payable.

Can I pay by Cheque?

To pay your bills by cheque, follow the payment advice on the back of your bill. As a minimum, we’ll need to have a completed giro slip with your account number and invoice number written on the back of your cheque.
To avoid late payment interest, please remember to allow seven working days for your cheque to clear our bank account.
