When purchasing a house in the UK through a mortgage, you do not necessarily need a minimum credit score, but it is essential to have a credit score that meets the lenders’ requirements to qualify for a mortgage.

Lenders have different approaches to risk, so the score you need may vary depending on the lender. Some lenders may require higher scores than others.

This article will explain how credit scores operate and the minimum score typically needed for purchasing a house.


What is a credit score?

Your credit score is determined by the three credit reference agencies, Experian, Equifax and TransUnion.

Each agency has its scoring system, so you will receive different scores from each one. For instance, your Experian score will be rated out of 999, your Equifax score will be out of 700, and TransUnion’s score will be out of 710.

Credit agencies may provide different scores, but it won’t matter if their information about you is accurate. This won’t impact your borrowing capability.

Lenders will need a higher credit score to approve your mortgage application if you have a smaller mortgage deposit.

What is a good credit score?

Each credit reference agency has its definition of a ‘good’ credit score. Experian considers a score of 700 or more good, while a score of 800 or more is excellent. On the other hand, an excellent score with Equifax is generally around 475.

TransUnion provides a credit score rating of five based on your credit score. If your score falls between 628 and 710, you will receive the highest rating of 5, considered excellent.

Lenders are more willing to lend to individuals with high scores as they perceive them as less risky borrowers.

What is a bad credit score, and how will it affect my chances of getting a mortgage?

A low credit score increases the chances of your mortgage application being rejected. Nevertheless, if your score is lower than expected, it does not necessarily mean your mortgage application will automatically decline.

When you apply for a mortgage, lenders consider several factors besides your credit score. It can be beneficial if you have a positive history as their customer, a stable income that can cover monthly repayments easily, and a substantial deposit of at least 10% of the property value.

If you have experienced credit issues, you may still be eligible for a mortgage from a lender specialising in such situations. It is advisable to seek expert guidance to determine which lenders suit your needs.
