An Invoice details the amount for Trading Charges, Default Charges and/or ad-hoc charges that you accrued since your last Invoice. It details the date you must pay these charges by (the Payment Date) and is your Tax Invoice.
Backing Sheets provide a breakdown of your Trading Charges, Default Charges and/or ad-hoc charges where such charges exist for the associated Invoice.

How are these documents delivered?

Invoices – You will receive by e-mail
Backing Sheets will be available to download from the Elexon Portal once an Invoice is issued.

When do I receive my Invoice?

The FAA will only send you an Invoice:

When the sum of your Trading Charges, Default Charges and/or ad-hoc charges exceeds the Invoice Threshold Limit;
On a Quarter Date; or
Under certain exceptional circumstances, such as if your Party is withdrawing from the BSC, is a Defaulting Party or has changed its VAT status.

The Invoice Threshold Limit is set at £500. The BSC Panel will occasionally review this. The FAA will send you an Invoice when you accumulate an amount that you owe or are owed which exceeds, or is equal to, this Threshold Limit. Therefore, the frequency that you receive Invoices will depend on your business.

Quarter Dates refer to the quarterly VAT period end dates at the end of March, June, September and December. The FAA will issue you with an Invoice for each Quarter Date, regardless of the monetary Invoice Threshold Limit or whether an Invoice was previously triggered within the quarter. If the last day of the quarter falls on a non working day, your Invoice will be issued to you on the last working day of the quarter.

When do I receive my Backing Sheets?

Backing sheets will only be issued when there is a threshold breach or quarter dates, along with the associated Invoice.
They will specify the related Invoice Number
A Trading Charges backing sheet will be produced for each calendar day, but these will only be available for download once the Invoice has been issued

Format of Invoices and Backing Sheets

Invoices are in PDF.

Backing Sheets are available in PDF and CSV Format on the Elexon Portal.

The Trading Charge backing sheets are delivered in unencrypted ASCII pipe delimited format.(.DAT) This format is meant for loading into applications such as MS Excel (or your own system) rather than direct interpretation.

Process Overview

An Invoice is issued by the FAA showing the amount you need to pay to the BSC Clearer, or that the BSC Clearer needs to pay you. It can cover charges for several calendar payment dates and must be paid in full by the Payment Date on the Invoice.

The Invoice acts as your tax invoice. The Customer is liable for VAT under the reverse charge mechanism.
