European Direct Debit Authorization
/ What is this form?
SEPA (Single Euro Payments Area) is the European payment integration initiative covering 36 countries — all EU member states plus Iceland, Liechtenstein, Norway, Switzerland, and the United Kingdom (which remains in SEPA post-Brexit). SEPA Direct Debit is the standardized system for recurring automatic payment collection used across these countries. In 2024, over 22.5 billion SEPA direct debit transactions were processed, making it the backbone of recurring payment infrastructure in Europe.
A SEPA Direct Debit Mandate is the signed authorization from a payer (you) to a creditor (a company or individual) allowing them to collect specified payments from your bank account on agreed dates. There are two schemes: SEPA Core Direct Debit (consumer-facing, with an 8-week no-questions-asked refund right) and SEPA B2B Direct Debit (business-to-business, faster processing, no automatic refund right).
SEPA mandates are used for virtually all recurring payment relationships in participating countries: rent, utilities, insurance, gym memberships, internet and mobile contracts, magazine subscriptions, and loan repayments. The mandate stays in force until cancelled by either party. Millions of new mandates are signed annually as consumers establish new contracts and businesses.

/ Key fields explained
| Field | What to enter | Common mistake |
|---|---|---|
| IBAN | Your full IBAN — typically 18-27 characters for most European countries (e.g. Germany: DE + 20 digits, UK: GB + 22 characters). Available on your bank statement, online banking app, or by asking your bank. | Entering the account number and sort code instead of the IBAN — in SEPA countries, only IBAN is accepted. Convert using your bank's IBAN calculator if needed. |
| BIC / SWIFT Code | Your bank's 8- or 11-character BIC (e.g. DEUTDEDB for Deutsche Bank, BARCGB22 for Barclays). For domestic SEPA transactions within the same country, BIC may be optional since 2016. | Using a BIC for the wrong branch — if your bank has multiple BICs (for different branches or services), use the one corresponding to your account's branch. |
| Mandate Reference (Mandatsreferenz) | Pre-assigned by the creditor — copy it exactly from the mandate form. Do not change or leave blank. | Filling in your own reference number — the Mandatsreferenz is assigned by the creditor and is used to track and dispute specific mandates. Using a different number invalidates the mandate. |
| Type of Payment (One-Off vs Recurring) | Most mandates are 'recurring' (wiederkehrend). One-off mandates are for single transactions. Check the box that corresponds to your agreement with the creditor. | Checking 'one-off' when the mandate is intended for recurring payments — this means the mandate becomes invalid after the first collection, and further debits can be disputed. |

/ Frequently asked questions
Contact your bank immediately. For SEPA Core mandates, you have 8 weeks from the debit date to request a refund, no reason needed. For debits with no mandate at all, you have 13 months. Request the reversal at your bank's counter or through online banking — banks are obligated to process it.
Yes. Notify the creditor in writing (email or letter) that you are cancelling the mandate, and separately instruct your bank in writing to block further collections from that creditor identifier. Both steps together ensure the cancellation is effective.
Yes. The UK remains a SEPA participant for payment purposes. British IBANs are valid in SEPA transactions and UK businesses can continue to collect and make SEPA payments. However, Brexit has added some friction for cross-border B2B mandates in certain sectors.
SEPA Core is the consumer scheme — any person with a bank account can use it, collections can happen 1 business day after mandate setup, and you have an 8-week no-questions-asked refund right. SEPA B2B is business-to-business — both parties must be businesses, collections are faster (same day or next day), and there is no automatic refund right.
