Worrying about your credit score is completely normal when you’re buying your first home. Many first-time buyers assume they need a perfect score to get a mortgage – but that isn’t always the case.

This guide explains how credit scores work in the UK, what mortgage lenders really look for, and how to put yourself in the best possible position before you apply.


Is There a Minimum Credit Score for a Mortgage?

There isn’t one single credit score that guarantees mortgage approval.

This is because:

  • Different lenders use different credit scoring systems
  • Each lender sets its own criteria
  • Lenders look at your overall credit history, not just a number

Your credit score is important, but it’s only one part of the decision.


What Mortgage Lenders Look For Instead

When reviewing your application, lenders focus on how you’ve managed credit over time.

They’ll usually look at:

  • Whether you pay bills and credit commitments on time
  • Any missed or late payments
  • Defaults, CCJs, or insolvency
  • How much of your available credit you’re using

A well-managed credit history often matters more than a high score alone.


Common Credit Issues for First-Time Buyers

Some issues that can affect first-time buyers include:

  • Missed payments on mobile phone contracts
  • Using a high percentage of available credit
  • Applying for multiple credit products in a short time
  • Buy Now, Pay Later services showing on your credit file

These don’t always mean you can’t get a mortgage, but they may limit lender choice.


How Your Deposit Affects Credit Score Requirements

If you have a larger deposit, lenders may be more flexible.

For example:

  • 5% deposit – stricter credit requirements
  • 10%+ deposit – wider lender options
  • 15%+ deposit – more flexibility in some cases

This is why deposit size and credit history are closely linked.


How to Check Your Credit Score

Before applying for a mortgage, it’s a good idea to check your credit report.

You can do this for free using UK credit reference agencies such as:

  • Experian
  • Equifax
  • TransUnion

Checking your own credit report will not affect your score.


You can also check your credit score with CheckMyFile, which offers a free 30-day trial by clicking here - you can cancel at any time online and it is just £14.99 per month after your trial ends.


How to Improve Your Credit Score Before Applying

Simple steps that may help include:

  • Making all payments on time
  • Reducing credit card balances
  • Avoiding new credit applications
  • Registering on the electoral roll

Even small improvements can make a difference.


First-Time Buyer Credit Score FAQs

Can I get a mortgage with bad credit?

Some lenders will consider applications with historic credit issues, depending on the circumstances.

Do lenders see my full credit history?

Yes – lenders usually review your credit report rather than just your score.

Should I wait to apply if my score isn’t perfect?

Not necessarily. Getting advice early can help you understand your realistic options.


Get Reassurance Before You Apply

If you’re a first-time buyer worried about your credit score, you’re not alone. Many successful buyers start out with concerns just like yours.

Speaking to a mortgage adviser before you apply can help you understand where you stand and avoid unnecessary declines.
