## How UK Direct Debit works

UK Direct Debit follows the standard direct debit flow: **authorize**, **notify**, **initiate**, and **settle**.

1. **Collect authorization**
   The payer provides consent to debit their bank account. This is known as a Direct Debit instruction.

2. **Provide advance notice**
   The payer must be notified in advance of the amount and timing of the debit.

3. **Initiate the debit**
   Payments are submitted through the Bacs system according to scheme timelines.

4. **Settle funds**
   Funds are transferred over multiple business days.
