Fill in a Direct Debit mandate online
A Direct Debit mandate, or Direct Debit Instruction (DDI), is your written permission for an organisation to collect payments from your bank or building society account. It holds your account name, account number and sort code, plus the organisation’s service user number and your reference. You return it to the organisation, not to your bank.
A Direct Debit instruction asks for your name, address, sort code, account number and a signature — and it usually arrives as a PDF because the organisation has not got round to an online form.
Fill it in on screen and send it back the same day.

Filling it in, section by section
- Service user number
- This identifies the organisation collecting the money within the Direct Debit scheme. The organisation prints it in the top right of the form. You do not fill it in.
- For (organisation) official use only
- A box for the organisation’s own records. The form says it is not part of the instruction to your bank, so leave it empty.
- Name(s) of Account Holder(s)
- The name or names on the account the money will come from, as your bank holds them. The form has room for more than one name.
- Bank/Building Society account number
- Your account number, one digit to each box. Copy it from a statement or your banking app rather than from memory.
- Branch Sort Code
- Six digits in three pairs. Leave out the dashes if the form gives you one box per digit.
- Name and full postal address of your Bank or Building Society
- The form is addressed “To: The Manager”. Put your bank or building society’s name and address, including the postcode.
- Reference
- The organisation’s reference for you, such as a customer, policy or membership number. Use exactly what they give you, because it links the payment to your account with them.
- Instruction to your Bank or Building Society, Signature(s) and Date
- Signing allows the named organisation to collect Direct Debits from your account, protected by the Direct Debit Guarantee. The wording says the instruction may stay with the organisation and be passed to your bank electronically. That is why you send it back to the organisation. There is room for more than one signature.
- The Direct Debit Guarantee
- A tear-off section that you detach and keep. The organisation must tell you in advance about any change to the amount, date or frequency. The scheme says this is normally 10 working days. If you are charged in error, you get a full and immediate refund from your bank. You can cancel at any time by contacting your bank.
Filling it in neatly
- Sort code and account number boxes are often character-separated; zoom in and place each number rather than typing a single string.
- Check the service user number and reference are already filled in by the organisation before you sign.
- Your bank details are sensitive: PDFpad keeps the document in your browser, but think about how you send it — email is not private.
- Keep a copy; the Direct Debit Guarantee is worth being able to point at.
Common mistakes
- Posting the form to your own bank, when the instruction goes back to the organisation that sent it.
- Putting your own name on the form when the account is in a partner’s or business’s name. The details must match the account the money comes from.
- Swapping two digits in the sort code or account number. Check them against a bank statement before you sign.
- Writing in the official-use box, or sending back the Guarantee instead of keeping it.
- Cancelling by telling only the organisation. The Guarantee says to cancel through your bank, which may want it in writing, and to tell the organisation as well.

Questions
- Can a Direct Debit mandate be signed electronically?
- Paperless Direct Debit is normal now, and most organisations accept a signed PDF. Some still require a wet signature — the form will say.
