How to improve credit score for mortgage

How to build a Strong Credit Score

June 24, 20253 min read

If you’re planning to apply for a mortgage in the near future, strengthening your credit report/file should be high on your list. A solid credit profile gives lenders confidence that you can manage debt responsibly, which can help you secure better mortgage deals.

What Is Your Credit Report and Why Does It Matter?

Your credit file is a record of how you’ve managed credit in the past. It includes things like credit cards, loans, mobile phone contracts, and any missed payments. Lenders use this information to assess how likely you are to repay what you borrow.

The stronger your credit profile, the more likely you are to be offered competitive mortgage rates and a wider choice of lenders.

Step 1: Check Your Credit Report Regularly

Start by getting a copy of your credit report. You can do this for free using services like Check My File, which pulls data from all three main UK credit reference agencies – Experian, Equifax, and TransUnion.

Review your report carefully. Look out for any mistakes or outdated information that could be affecting your score. If you spot something wrong, raise it with the credit agency straight away.

Step 2: Understand What Affects Your Credit Score

Here are some of the main things lenders consider:

  • Payment history – Missed or late payments can have a big impact.

  • Credit utilisation – Using a high percentage of your available credit can lower your score.

  • Credit history length – The longer your track record, the better.

  • Recent applications – Lots of new applications in a short time can make you look risky.

  • Types of credit – A mix of credit cards, loans, and other accounts is generally positive.

Step 3: Keep Debt in Check

Try to keep credit card balances low and make repayments on time. If you can, pay off the full balance each month. Avoid opening lots of new credit accounts in a short space of time.

If you're struggling with debt, speak to your broker. We can often recommend small changes that will help improve your profile without needing drastic steps.

Step 4: Use Direct Debits to Stay on Track

Setting up direct debits for bills and credit repayments helps make sure you never miss a due date. Even a single late payment can have a lasting impact on your score.

Step 5: Don’t Overlook the Little Things

  • Get on the electoral roll at your current address. It’s a quick win that can boost your credit score.

  • Check your financial links. If you're still linked to an ex-partner or housemate with poor credit, it can affect your file. Ask the credit agencies to remove outdated links.

  • Tell your broker if you’ve recently paid off any debts. Updates to your credit file can take several weeks to show, and we can factor that in when advising you.

Small Steps Make a Big Difference

Improving your credit file won’t happen overnight, but with consistent habits and a bit of forward planning, you can put yourself in a much stronger position for mortgage approval.
