Can You Get a Mortgage With Open Low Balance Defaults?

If you have one or more open defaults showing on your credit file — especially small balances left unpaid — you might be wondering whether a mortgage is still possible. These types of defaults often catch people out because the amounts are low, sometimes under £200, and yet they still show as “outstanding” on your credit report.

The good news? Yes, you can get a mortgage with open, low-balance defaults. But the lender options depend on when the default was registered, the type of default, how many you have, and your overall financial picture.

In this guide, we explain exactly how lenders assess open defaults, what you can do to improve your chances, and the best steps to take before applying.

Let’s break it down clearly and simply.

Do Lenders Allow Mortgages With Open Defaults?

Some do — some don’t.
Most high-street lenders decline applications where any default is still open, regardless of the balance. Even a £30 mobile phone default can trigger an automatic decline.

Specialist lenders, however, take a more flexible approach. They assess:

• How old the default is
• How low the outstanding balance is
• Whether it’s an isolated issue or part of a pattern
• What type of creditor it involved (e.g., telecom, utilities, credit card)
• Whether your finances have been stable since

This is similar to how lenders assess previous issues like bankruptcy discharged over time or debt management plans, which we cover in more detail in our other guides.

What Counts as a “Low-Balance” Default?

A low-balance default usually refers to a default of £500 or less — though some specialist lenders consider anything under £250 to be “minor.”

Common examples include:

• Mobile phone contract arrears
• Old broadband bills
• Small credit card balances
• Buy-now-pay-later accounts
• Utility bills

It’s not the amount that matters to lenders — it’s the presence of an unpaid default that indicates missed commitments.

How Old Does the Default Need to Be?

Age is one of the biggest factors.

Here’s how lenders typically view default age:

• Under 6 months old: Very few lenders will consider you
• 6–12 months old: Some specialist lenders may consider you, but the deposit required is likely higher
• 12–24 months old: More lenders become available, especially if the balance is small
• Older than 24 months: Many specialist lenders are open to applicants even if the default is still unpaid
• Older than 36 months: Some lenders may ignore low-balance defaults completely

Remember: even if a default is open, the older it is, the less weight it carries — especially if you’ve been stable since then.

Should You Repay an Open Low-Balance Default Before Applying?

This is where things get counterintuitive.

Paying off a default does not remove it from your credit file. It simply marks it as “satisfied.”

Paying it can help in two situations:

1. Your chosen lender requires defaults to be settled
2. The balance is so small that repayment provides reassurance

However, some lenders prefer not to pay off a default too close to an application because it triggers fresh activity on your credit file.

As brokers, we usually look at the lender list first. If your best option requires the default to be settled, we plan accordingly. If the lender is happy with open defaults, we advise leaving it untouched until after the mortgage is complete.

What Types of Defaults Are Most Accepted?

Defaults involving essential services tend to be more accepted by specialist lenders.

These include:

• Mobile phone or broadband contracts
• Gas, electric, or water bills
• Small retail credit accounts

Defaults involving credit cards, loans, or overdrafts are viewed more seriously because they indicate struggles with borrowing rather than service bills.

Defaults connected to priority debts (tax, council, rent arrears) are treated most seriously.

---

How Many Defaults Can You Have?

Specialist lenders each have their own criteria, but the general pattern is:

• One or two low-balance defaults: Often acceptable
• Three or more defaults: Depends on age and pattern
• Multiple recent defaults: Harder, but not impossible with niche lenders

A cluster of low-balance defaults from the same period (e.g., a difficult month where everything bounced) is often easier to explain than sporadic issues over time.

---

What Deposit Do You Need With Open Defaults?

Expect higher deposit requirements compared with a clean credit file.

Typical ranges:

• With open defaults under £250: 10–15% deposit
• With open defaults under £500: 15–20% deposit
• With several open defaults: 20–30% deposit, depending on age and type

Remember: lenders care far more about recent behaviour than old issues. Your bank statements play a major role here, as we explain in our dedicated guide.

How Do Lenders Assess Affordability With Open Defaults?

Defaults don’t automatically reduce your borrowing capacity, but they can affect which lender you qualify with. Some lenders limit the income multiple (e.g., 4x instead of 4.5x) when defaults are present.

What lenders look for alongside defaults:

• Stable income
• Steady address history
• No recent missed payments
• Consistent rent payments
• Sensible use of overdraft
• No excessive gambling or risky transactions

Even if you have open defaults, strong recent conduct can offset concerns and lead to an approval.

---

Can You Get a Mortgage With Open Defaults as a First-Time Buyer?

Yes — being a first-time buyer doesn’t make things harder, but you need to be matched to the right lender.

We frequently help first-time buyers who have:

• Old telecom defaults
• Small unpaid balances left from student years
• Forgotten accounts from previous addresses

It’s very common — and fully manageable with the right guidance.

If you also fall into another category (e.g., self-employed or one-income applications), we cover those scenarios in more detail in our other guides.

Steps to Improve Your Chances Before Applying

Check all three credit files

Some defaults appear on one file but not another. You should check:

• Experian
• Equifax
• TransUnion

Update your address history

Make sure your addresses and dates match across all records.

Avoid new credit

Fresh borrowing shortly before applying can worry lenders.

Build a clean 3–6 month bank statement record

Lenders value recent behaviour more than past mistakes.

Consider settling the default (if advised)

This depends on the strategy for your lender — we’ll tell you what benefits your case most.

---

What If Your Bank Has Already Said No?

High-street lenders rarely accept open defaults — even small ones. Their systems automatically decline these cases.

However:

• Specialist lenders
• Manual underwriters
• Flexible criteria lenders

… routinely approve mortgages where low-balance defaults are present, especially if the issues are older or explainable.

Many clients come to us after being declined by their bank, and still achieve approval within days once matched to the right lender.
