Your Overdraft Has Been Reduced, Withdrawn or Refused
A business overdraft is normally repayable on demand and reviewed periodically, so it is not committed funding, and a reduction often reflects the bank's own appetite rather than anything the business has done. The useful response is not to chase another overdraft but to work out what the headroom was actually funding, because a supplier-to-customer timing gap, a recurring tax bill and equipment bought out of cashflow each have a better-fitting facility than an overdraft ever was.
First, work out what it was really funding
Overdrafts get used for everything, which is why losing one feels like losing the whole safety net. Separating the uses is what makes the replacement obvious. If it bridged the gap between paying suppliers and being paid by customers, that is a receivables cycle. If it absorbed a VAT or Corporation Tax bill every quarter, that is a recurring known event, not a fluctuation. If it quietly funded a van or a machine, that is an asset purchase that was never structured as one.
What the headroom was doing, and what fits it better
- Bridging supplier payments before customers pay: invoice finance advances against the ledger, so the facility grows with sales instead of being capped by a review.
- Absorbing quarterly VAT or tax: VAT and tax funding spreads a known bill rather than leaving it to fluctuate against a limit.
- Buying equipment out of cashflow: asset finance secures on the asset itself, which is usually cheaper than unsecured headroom.
- General trading fluctuation: a working-capital or revolving facility priced and structured for the purpose.
Hardcore borrowing is usually the real trigger
If the account never swings back into credit, the overdraft has stopped being a fluctuation buffer and has become term borrowing that is neither priced nor structured as term borrowing. Banks watch for exactly that at review, and it is the most common reason a limit is cut when nothing else has changed. It is also the clearest evidence that the underlying need was never an overdraft, which makes the replacement conversation easier rather than harder.
Check the security position before you apply elsewhere
If the bank holds a debenture, its security affects what a new funder can take, and that is a ranking question rather than an appetite one. It is worth establishing early, because it sets the timetable more often than the credit decision does. The same issue is covered under second facilities on the existing finance hub.

Common questions
Can the bank really withdraw an overdraft with no warning?
Usually yes. A business overdraft is normally repayable on demand and reviewed periodically, which means it is not committed funding in the way a term facility is. Many businesses discover this only at the review. Check the facility letter for the notice position, because what you are entitled to is set out there rather than by custom.
Why has it been reduced when nothing has gone wrong?
Often nothing about the business has changed. Overdraft limits move with the bank's own appetite, sector view and capital position as well as with your numbers. Common triggers on the business side are a hardening of the credit score, sustained hardcore borrowing where the account never swings back into credit, a late filing, or a sector the bank has decided to reduce exposure to.
What replaces overdraft headroom?
It depends what the overdraft was actually funding. If it covered the gap between paying suppliers and being paid, invoice finance or a revolving working-capital facility maps onto that cycle far better than an overdraft did. If it was absorbing a tax bill each quarter, VAT or tax funding is the direct answer. If it was funding equipment out of cashflow, asset finance releases the pressure. Replacing like for like with another overdraft is usually the hardest of the options, not the easiest.
Is hardcore borrowing a problem?
It is the thing banks watch most closely on an overdraft. If the balance never returns to credit, the facility is functioning as a term loan without being priced or structured as one, and that is typically what prompts a reduction at review. It is also the clearest signal that the underlying need is a term or working-capital facility rather than an overdraft.
Should I just move banks?
Rarely the fastest route on its own. A new bank will underwrite the same numbers, and moving the account takes time you may not have if the headroom is being withdrawn now. It is usually more effective to put the right facility against the actual need first, then review banking separately once the pressure is off.
Does a reduced overdraft affect other borrowing?
It can, in two ways. It reduces available headroom, which affects how you evidence liquidity to another lender. And if the bank holds a debenture, its security position affects what a new funder can take, which is a question of ranking rather than of appetite.
