What Credit Score Do You Need for a Mortgage? (And How to Improve It Fast)

If you’re preparing to apply for a mortgage, it’s natural to wonder: what credit score do you actually need?
The truth is that lenders don’t rely on one universal score — and your Experian, Equifax or TransUnion rating alone won’t decide your application.

Instead, lenders assess your overall credit behaviour, focusing on recent activity, repayment patterns, affordability and stability.

In this guide, we’ll explain:

• What credit score lenders typically look for
• How different scores affect your mortgage options
• What happens if your score is low
• Fast and effective ways to improve your score
• What specialist lenders consider (beyond just credit)

Let’s break it down clearly.

Is there a minimum credit score you need for a mortgage?

There isn’t a single “pass or fail” number — each credit agency uses its own scoring system.

Here are the typical score ranges:

Experian (0–999)

• Excellent: 961–999
• Good: 881–960
• Fair: 721–880
• Poor: 561–720
• Very Poor: Below 560

Equifax (0–1000)

• Excellent: 811–1000
• Good: 671–810
• Fair: 531–670
• Poor: 439–530
• Very Poor: Below 438

TransUnion (0–710)

• Excellent: 628–710
• Good: 604–627
• Fair: 566–603
• Poor: 551–565
• Very Poor: Below 550

But here’s the important part:

Lenders do not use these scores to approve or decline you.
They use their own internal scoring systems based on your real credit data, not the number you see on your report.

This means it’s possible to:

• Have a low Experian score and still get approved, or
• Have a high score and still be declined

Depending on what’s actually on your file.

So what credit score should you aim for?

As a general guide:

• Good or Excellent: Strongest chance with high-street lenders
• Fair: Many lenders will still consider you
• Poor: Specialist lenders become more important
• Very Poor: Options exist, but deposit and rates are affected

If your profile is Fair or Poor, it doesn’t automatically rule you out — especially if other factors are strong (income, bank statements, deposit).

What do lenders really look for on your credit file?

Rather than seeing a single score, lenders examine:

★ 1. Your payment history

Missed payments carry the most weight — especially within the last 12 months.

★ 2. Defaults or CCJs

These are accepted by some lenders, but deposit requirements usually increase.
See our guides on defaults and CCJs for more detail.

★ 3. How much credit you use

High utilisation (e.g., cards consistently above 50% of their limit) can reduce your options.

★ 4. Recent applications

Applying for lots of credit in a short space of time is a red flag.

★ 5. Length of credit history

A longer, stable record helps significantly.

★ 6. Your bank statements

This is often as important as the credit file itself.
We cover this fully in our guide on what lenders look for on bank statements.

Your lender won’t see your numerical score — they’ll see your financial behaviour. That’s what matters.

Can you still get a mortgage with a low credit score?

Yes — absolutely.

Applicants with “Poor” or even “Very Poor” scores are approved every day by specialist lenders who:

• Accept past credit issues
• Consider recent improvements
• Look at affordability more flexibly
• Understand the context behind historic problems

Low credit score mortgages do exist — you just need the right lender.

---

What if your credit score is low because you’ve never had credit?

This is extremely common.
Lenders call it a “thin file”, and it simply means you haven’t built a track record yet.

You can still get a mortgage, but you may need:

• Strong bank statements
• A stable income
• A clear explanation of your financial position

Building a small amount of positive credit can help (we’ll cover this below).

---

What if you have bad credit on your file?

Defaults, CCJs, missed payments and DMPs can all be considered — it depends on:

• How old the issues are
• Whether they’re satisfied
• The value of each issue
• Your deposit
• How your recent finances look

With bad credit, deposits usually start at:

• 5% for older or very small issues
• 10–25% for more recent or multiple issues

We help clients with all forms of adverse credit, so don’t worry if your file isn’t perfect.

---

Does a higher credit score always mean better rates?

Usually — yes.

Lenders reserve their best rates for cleaner credit files.
But this doesn’t mean your rate will be high forever — many clients remortgage to a better deal once their credit improves.

---

What credit score do you need for a mortgage with a 5% deposit?

Lenders offering 95% mortgages tend to prefer:

• No recent missed payments
• No active defaults or CCJs
• Good affordability
• Clean and consistent bank statements

However, specialist lenders sometimes accept applicants with older credit issues and still offer 5–10% deposit options.

If you’re unsure whether you fit the criteria, we can check your file and advise.

Fast ways to improve your credit score before applying

Here are the most effective steps — many of which improve your score within weeks:

1. Register on the electoral roll

One of the quickest improvements you can make.

2. Reduce credit card balances

Aim for below 50% of your limit — ideally below 30%.

3. Pay everything on time

Even one missed payment can reduce your lender choices.

4. Avoid new credit applications

Multiple checks in a short time can harm your profile.

5. Check your credit report for mistakes

Errors are more common than most people think.

6. Add a small amount of positive credit (carefully)

A low-limit card used lightly can help build history — but only if managed perfectly.

7. Keep your bank statements tidy

Lenders will review these closely alongside your credit file.

8. Clear old balances if possible

Small defaults or arrears can sometimes be settled quickly and improve your options.

If you’d like us to review your file and suggest personalised improvements, we’re happy to help.

Do lenders prefer Experian, Equifax or TransUnion?

Different lenders use different agencies:

• Some use Experian
• Some use Equifax
• Some use TransUnion
• Many use a combination

We always check all three reports to make sure there are no surprises.

---

What credit score do joint applicants need?

Lenders assess the combined profile.
A weaker applicant can pull down the overall score — but they can also sometimes be removed from the application if income allows.

We help clients structure their application in the way that gives them the strongest chance.

Key Takeaways

• There’s no fixed credit score required for a mortgage
• Lenders look at behaviour, not numbers
• Good and excellent scores unlock the most options
• Fair and poor scores still allow mortgages with the right lender
• You can improve your score quickly with simple steps
• Specialist lenders can help even with recent credit issues
