SEPA Direct Debit (SDD)

SEPA Direct Debit (SDD) is the scheme that allows a creditor, such as a utility, insurer, gym or supplier, to collect euro payments directly from a debtor's bank account anywhere in the Single Euro Payments Area, provided the debtor has signed a mandate authorising it. Unlike a SEPA Credit Transfer, which the payer pushes, a direct debit is pulled by the payee, which makes it suited to recurring bills and subscriptions with variable amounts.

The European Payments Council publishes two rulebooks: the SDD Core scheme, available to consumers and businesses, and the SDD Business-to-Business (B2B) scheme, for business debtors only. Both are supported by EU payments law, and the SEPA Regulation made them the standard for euro direct debits, replacing national schemes. Direct debit collection from customers in another SEPA country is a right protected by that regulation.

The SDD Core and B2B schemes launched in November 2009, more than a year after the credit transfer scheme. Take-up was slow until the SEPA Regulation set migration deadlines, the main one for the euro area falling in 2014. National direct debit systems, many of which had operated for decades with their own rules, were closed or converted. Existing national mandates were generally carried over so that customers did not have to sign new ones.

The mandate is the debtor's authorisation for the creditor to collect and for the debtor's bank to pay. It contains the creditor's name and creditor identifier, a unique mandate reference, the debtor's name and IBAN, and whether the mandate is for a single or recurring collection. Under the Core scheme the creditor keeps the mandate and does not have to send it to the debtor's bank; under B2B the debtor must also confirm the mandate with its own bank, which checks each collection against it.

Before each collection, the creditor must send a pre-notification telling the debtor the amount and date. The default notice period is 14 calendar days, but creditor and debtor can agree a shorter period, and many do so in their terms.

The creditor sends a collection file to its bank, usually as a pain.008 customer direct debit initiation message in ISO 20022 format, listing each debtor, amount, due date and mandate details. The creditor's bank passes the collections through a clearing mechanism to the debtors' banks, which debit the accounts on the due date. Settlement between banks takes place on that date. Collections must be submitted a minimum period before the due date, as set out in the rulebook and the clearing system's timetable.

The Core scheme gives consumers strong protection:

• No-questions refund. A debtor may ask for a refund of an authorised collection within eight weeks of the debit date, without giving a reason.
• Unauthorised collections. If no valid mandate exists, the debtor can claim a refund for up to 13 months after the debit date.
• Rejects and returns. The debtor's bank may reject or return a collection, for example for insufficient funds, a closed account or a debtor's instruction to block debits from a creditor.

The B2B scheme removes the eight-week refund right, giving creditors more certainty in exchange for stricter mandate checks by the debtor's bank. Returns and refunds are handled through standard exception messages, known collectively as R-transactions, and creditors track them through direct debit return processes and mandate management systems.

SDD is widely used for utilities, telecoms, insurance, loan repayments, memberships and taxes, and in business supply chains under the B2B scheme. It costs creditors less than card payments and works across borders in euros, allowing a company in one SEPA country to collect from customers in another with a single bank account. Drawbacks include the time needed to set up mandates, the risk of late returns and the long refund window, which exposes creditors to customers who dispute valid debits. Debtors' banks may also offer tools to whitelist or block creditors and to limit amounts, as required by EU law.

Because a creditor can initiate collections using only a debtor's IBAN and a mandate it holds, direct debits are vulnerable to fraudulent mandates, where criminals or rogue creditors collect without genuine authorisation. Banks therefore apply due diligence to creditors before granting direct debit facilities, monitor return rates and may require collateral. The refund right acts as the main consumer safeguard against such abuse.
