Credit Scores and Mortgages: How Your Credit History Can Affect Your Mortgage Application

By Maxim Cohen·13 July 2026·6 min read

If you're planning to apply for a mortgage, you've probably heard that your credit score is important. While your credit history plays a significant role, it's only one part of the overall assessment lenders make when deciding whether to offer a mortgage.

Every lender has its own approach to assessing applications. Some place greater emphasis on credit history, while others may take a broader view of your overall financial circumstances.

Understanding how your credit history works and preparing before you apply can help you make informed decisions and avoid unnecessary delays.

At The UK Adviser, we help clients understand how lenders assess mortgage applications and identify lenders whose criteria may suit their individual circumstances.

What Is a Credit Score?

A credit score is a numerical rating produced by a credit reference agency based on the information it holds about your borrowing and repayment history.

Different credit reference agencies use different scoring systems, so your score may vary between providers.

Mortgage lenders do not all use the same score, and many rely on their own internal assessment alongside information provided by credit reference agencies.

For this reason, there is no universal "pass mark" for getting a mortgage.

What Is a Credit Report?

A credit report contains information about your financial history.

It may include:

  • Current and previous addresses
  • Electoral roll registration
  • Credit cards
  • Loans
  • Mortgages
  • Mobile phone contracts
  • Missed or late payments
  • Defaults
  • County Court Judgments (CCJs)
  • Bankruptcies
  • Individual Voluntary Arrangements (IVAs)
  • Financial associations
  • Credit searches

Mortgage lenders often review this information as part of the application process.

Why Does Your Credit History Matter?

Your credit history helps lenders understand how you've managed borrowing in the past.

They may consider:

  • Whether repayments have been made on time
  • The amount of existing borrowing
  • The length of your credit history
  • Previous credit difficulties
  • The number of recent credit applications
  • Overall financial management

Your credit history is only one part of the assessment. Lenders also consider affordability, income, deposit and property details.

What Do Mortgage Lenders Look For?

Every lender has different criteria, but they commonly assess:

  • Payment history
  • Outstanding borrowing
  • Credit utilisation
  • Electoral roll registration
  • Stability of address history
  • Financial commitments
  • Credit searches
  • Previous insolvency

Different lenders have different attitudes towards previous credit issues.

Common Credit Issues

Missed Payments

Occasional missed payments may not prevent a mortgage application, but lenders are likely to consider when they occurred, how many there were and the overall pattern of account conduct.

Defaults

A default indicates that a lender has closed an account after a prolonged period of missed payments.

Some lenders consider applicants with historic defaults, while others apply stricter criteria.

County Court Judgments (CCJs)

A CCJ may affect the range of lenders willing to consider an application.

Factors such as the age of the CCJ, whether it has been satisfied and your current financial circumstances may all be relevant.

Bankruptcy and IVAs

Previous bankruptcy or an Individual Voluntary Arrangement (IVA) may reduce the number of lenders available, although some lenders will consider applications once sufficient time has passed and eligibility criteria are met.

Does Checking Your Credit Score Affect It?

Checking your own credit report is generally considered a soft search and does not usually affect your ability to obtain a mortgage.

Regularly reviewing your report can help you identify incorrect information before applying.

What Is a Hard Credit Search?

Some lenders perform a hard credit search when assessing a mortgage application.

A hard search becomes part of your credit history and may be visible to other lenders.

An Agreement in Principle may involve either a soft or hard search, depending on the lender.

How Can You Improve Your Credit Profile?

While there are no guarantees, you may strengthen your mortgage application by:

  • Making payments on time.
  • Registering on the electoral roll.
  • Correcting errors on your credit report.
  • Reducing outstanding borrowing where appropriate.
  • Avoiding unnecessary credit applications shortly before applying.
  • Managing your bank accounts responsibly.
  • Keeping your credit utilisation at a sensible level.

Improvements often take time, so planning ahead can be beneficial.

Should You Close Old Credit Accounts?

Not necessarily.

Closing long-standing accounts may reduce the length of your credit history.

Whether this is appropriate depends on your individual circumstances.

If you're unsure, seek professional advice before making significant changes to your credit arrangements.

Does Being Self-Employed Affect Your Credit Score?

No.

Being self-employed does not automatically affect your credit score.

However, self-employed applicants must also demonstrate income and affordability, which are assessed separately from credit history.

Can You Get a Mortgage With Bad Credit?

Possibly.

Some lenders consider applicants who have experienced previous credit difficulties.

The outcome will depend on factors such as:

  • The nature of the credit issue
  • When it occurred
  • Whether it has been resolved
  • Your current financial position
  • Deposit size
  • Affordability
  • The lender's criteria

Professional advice can help identify lenders who may be appropriate for your circumstances.

Mistakes to Avoid Before Applying

Common mistakes include:

  • Applying for multiple forms of credit.
  • Missing regular payments.
  • Ignoring errors on your credit report.
  • Taking out significant new borrowing.
  • Making several mortgage applications at the same time.
  • Failing to disclose previous credit issues.

Preparing in advance may improve the overall application process.

Why Professional Advice Matters

Different lenders assess credit history in different ways.

An experienced mortgage adviser can:

  • Review your circumstances.
  • Explain how lenders may view your credit profile.
  • Identify lenders whose criteria may be appropriate.
  • Help you prepare your application.
  • Reduce the risk of unnecessary applications.

Every mortgage application is assessed individually.

Frequently Asked Questions

What credit score do I need for a mortgage?

There is no single minimum credit score that guarantees mortgage approval. Every lender uses its own assessment process and lending criteria.

Can I get a mortgage with missed payments?

Some lenders will consider applicants with previous missed payments, depending on the circumstances and the lender's criteria.

Should I check my credit report before applying?

Yes. Reviewing your credit report before applying can help identify errors and ensure the information held is accurate.

Does an Agreement in Principle affect my credit score?

Some lenders use a soft search, while others may carry out a hard search. Your adviser can explain the approach used by the lender.

Can I improve my credit score quickly?

Building a stronger credit profile usually takes time. Making payments on time, correcting errors and managing borrowing responsibly may help over the longer term.
