Overdreyft Buffer is arranged overdraft in the Current accounts range, used for illustrating the cost of a short-lived current-account shortfall. Its live rate card, summary and worked tables sit above this text and update whenever the product record changes.
Know which amount the limit describes
For Overdreyft Buffer, the range is £0.00 to £1,000.00. For a savings product it is the opening and maximum principal; for an ISA it is the demo annual allowance; for a card or overdraft it is an assumed credit limit; for the mortgage it is an advance range; and for investments it is the minimum lump sum and any allowance. An interest credit may take savings just above the stated principal cap; further deposits then pause.
Before you increase the balance
| Check | Why it matters |
|---|---|
| Minimum | Amounts below the model minimum do not qualify for this product scenario. |
| Maximum or allowance | Projection examples stay within the stated principal cap or demo allowance. |
| Already at the cap? | Assume no further additions; accrued interest or growth is still credited. |
| Credit limit | Available borrowing is a limit less debt already used, not income or savings. |

What the example does not promise
All figures are invented and shown to make the demo useful to read and crawl. No money is held, no application is available, and no deposit-protection, regulatory or tax-wrapper status is claimed. Calculations do not account for personal tax, inflation or unstated changes in rates. The fictional bank manager can guarantee only that the next paragraph contains no real acorns.
