Your Spare Overdraft Isn't Invisible: What Lenders See Before You Apply

Most of us treat an overdraft the way we treat the smoke alarm: it's there, we're vaguely glad about it, and we don't think about it again until something goes wrong. But a spare £250 facility on your current account isn't just a quiet arrangement between you and your bank. It's on your credit file, updated month after month, and it will be sitting in front of a lender when you ask for a loan.

That's not a reason to panic. It is a reason to know what's being shown.

Why a limit you've never used still appears at all

Banks report current account data to the credit reference agencies — Experian, Equifax and TransUnion — on a rolling basis. That report includes the overdraft limit you've been given alongside the balance you're actually using.

So even if your balance has been in credit since 2021 and the £250 has never been touched, the file says something like: limit £250, balance £0. Nothing owed. But also: £250 of borrowing already available to you, ready to be drawn whenever you fancy.

Lenders don't see that as debt. They see it as capacity.

What the lender does with that number

When you apply for a loan, the affordability assessment isn't just about what you currently owe. It's about what you could owe if you used everything you've already got access to.

A decent underwriter will look at your total available credit — overdraft limits, card limits, catalogue accounts, buy-now-pay-later facilities where they're visible — and ask a fairly blunt question: if this person drew on all of it at once, could they still cope?

A single £250 overdraft is rarely going to be the deciding factor. Stacked up with a couple of credit cards and a store account, though, the picture shifts. Say you take home £1,900 a month, you've got £1,500 of card limits, an £800 catalogue account and that £250 spare overdraft. That's £2,550 of potential borrowing before anyone hands you a penny more. On a modest income, a cautious lender may treat some of that as money you're likely to spend.

Check first, decide second

Before you change anything, look at what's actually being reported. You can get your statutory credit report free from each of the three main agencies, and it's worth checking all of them because not every bank feeds every agency.

Look for:

• Current account entries showing an overdraft limit
• Old accounts that were closed but still display a limit
• Anything you'd forgotten about entirely — a student account from years back, a joint account you no longer use

If something's wrong — a limit that's higher than you agreed, an account you closed that's still showing as open — dispute it. Errors are more common than people assume.

The argument for trimming it

Reducing a limit you don't use does a few things at once. It lowers your total available credit, which can make you look less stretched. It removes a facility you might be tempted to lean on in a bad month. And it's a small, visible sign of someone managing their borrowing deliberately rather than accumulating it.

There's a timing point here that catches people out. Don't slash limits the week before you apply. Sudden changes to your credit file look odd, and if a lender sees a limit drop to zero two days before a loan application, it can read as someone tidying up under pressure. Give it a couple of statement cycles.

Also: don't close the account itself. An old current account with a long, clean history is doing you favours. Trim the facility, keep the relationship.

The argument for keeping the buffer

Here's the counterpoint, and it's a fair one. A £250 overdraft at 40% EAR is expensive money, but it's a great deal cheaper than a short-term loan or a missed direct debit. If cancelling it leaves you with genuinely nothing between payday and a broken boiler, you've traded a small credit-file blemish for a real-world risk.

Some accounts also come with cheaper arrangements — packaged accounts, graduate accounts, a few building society current accounts — where the overdraft is interest-free or close to it. Those are worth keeping if you qualify.

Weighing the two

A reasonable middle path: keep a facility roughly the size of one genuine emergency, and reduce anything above it. If you've got a £1,000 overdraft and you've never been more than £200 into it, £250–£300 might be plenty. You keep the safety net, and the lender sees a smaller number when they add up what you could borrow.

And if you do use the overdraft, watch the timing. Being £200 down on the day you apply matters far more than the limit itself, because utilisation is the signal that actually reads as strain.

A short sequence that works

1. Pull all three credit reports.
2. Note every overdraft limit against what you actually use.
3. Decide on a figure you'd honestly be comfortable drawing in an emergency.
4. Reduce anything above that — ideally a few months before you apply, not days.
5. Leave the account open.
6. Re-check the file a month later to confirm the change has landed.

None of this guarantees a better loan offer. Underwriters weigh income, existing commitments, payment history and a dozen other things. But an unused overdraft is one of the few levers entirely within your control, and it's surprising how few people pull it.
