Quick answer: There is no single credit score needed to buy a house in the UK. Mortgage lenders use different criteria, and your credit score is only one part of the application. They will also look at your income, deposit, debts, affordability, employment status and credit history. A lower score does not always mean you cannot get a mortgage, but it may limit your lender options.
If you are getting ready to buy a house, your credit score is probably one of the first things you will start worrying about. It is easy to assume there is a fixed number you need before a mortgage lender will consider you, but in the UK, it is not quite that simple.
There is no single credit score needed to buy a house. Mortgage lenders use different criteria, and your credit score is only one part of the application. They will also look at your income, deposit, affordability, debts, employment, credit history and the type of mortgage you need.
At Key Mortgage Advice, we help buyers understand how lenders may view their circumstances before they apply. Whether you are a first-time buyer, moving home or looking to remortgage, our advisers can help you work out what may be realistic based on your wider financial position.
What Is A Credit Score?
A credit score is a number used by credit reference agencies to show how you have managed borrowing and repayments in the past. It is based on information in your credit report, such as loans, credit cards, overdrafts, missed payments, defaults, credit searches and whether you are registered on the electoral roll.
Your credit score can be used as a guide to your financial behaviour, but it is not the only thing mortgage lenders consider. Lenders usually review the details behind your credit file rather than relying only on the score you see through a credit reference agency.
Credit checks may be used by:
- Mortgage lenders
- Loan and credit card providers
- Landlords or letting agents
- Some employers, depending on the role and sector
For mortgage applications, your credit history helps lenders assess risk. A strong credit record can support your application, while missed payments, high debts or recent credit issues may make some lenders more cautious.
Is There A Minimum Credit Score To Buy A House In The UK?
No, there is no fixed minimum credit score needed to buy a house in the UK. Different lenders use different systems, and credit reference agencies do not all score people in the same way.
This means a score that looks “good” with one agency may not mean the same thing with another. A lender may also make its own assessment using your credit file, income, deposit and affordability rather than simply approving or declining you based on a single number.
That said, a stronger credit profile can improve your chances of being accepted and may give you access to more lender options. If your score is low, or if you have had credit problems in the past, you may still be able to get a mortgage, but your options could be more limited.
What Is A Good Credit Score For A Mortgage?
A good credit score depends on which credit reference agency you are using. Experian, Equifax and TransUnion all use different scoring systems, so there is no single UK-wide number that counts as “good” for every mortgage lender.
As a general rule, the stronger your credit history, the better your chances are of being considered by a wider range of lenders. However, mortgage lenders are usually more interested in the full picture than the score alone.
For example, two people could have similar credit scores but very different mortgage outcomes. One person may have a stable income, low debt and a strong deposit. Another may have high credit card balances, recent missed payments or several recent credit applications. The score is only part of the story.
Experian, Equifax And TransUnion Credit Scores Explained
In the UK, the three main credit reference agencies are Experian, Equifax and TransUnion. Each one can hold slightly different information about you and may use a different scoring range.
| Credit reference agency | What to know |
|---|---|
| Experian | Uses its own scoring system and credit report data to give an indication of your credit health. |
| Equifax | Uses a separate scoring model, so the number may look different from your Experian score. |
| TransUnion | Used by services such as Credit Karma and may show different information depending on what lenders report. |
It is sensible to check all three reports before applying for a mortgage. This helps you spot mistakes, understand what lenders may see and avoid surprises during the application process.
What Do Mortgage Lenders Actually Look At?
Mortgage lenders look at more than your credit score. They need to decide whether the mortgage is affordable and whether you are likely to keep up with repayments.
| Factor | Why it matters to lenders |
|---|---|
| Credit history | Shows how you have managed borrowing and repayments in the past. |
| Deposit size | A larger deposit can reduce lender risk and may improve your options. |
| Income | Lenders need to see that your mortgage payments are affordable. |
| Existing debts | Credit cards, loans and other commitments can affect affordability. |
| Employment status | Stable income can support your application. Self-employed applicants can still be considered, but may need to provide different evidence. |
| Recent applications | Multiple hard searches in a short period can make some lenders more cautious. |
This is why a credit score alone does not decide whether you can buy a house. A lender may still consider an application with a lower score if the rest of the case is strong, depending on their criteria.
Can You Get A Mortgage With A Low Credit Score?
It may be possible to get a mortgage with a low credit score, but your options may be more limited. Some lenders may decline the application, while others may consider it if your income, deposit and recent credit conduct are strong enough.
A lower credit score may mean:
- Fewer lenders are available
- You may need a larger deposit
- You may not qualify for the lowest rates
- The lender may ask more questions about your credit history
- Your application may need more careful preparation
If you are worried about your score, it is usually better to speak to a broker before applying directly to lenders. Applying to unsuitable lenders can lead to unnecessary credit searches and avoidable declines. Naturally, the mortgage system chose to make “asking the wrong person” part of your permanent-looking record. Very elegant.
Low Credit Score vs Adverse Credit
A low credit score and adverse credit are connected, but they are not always the same thing.
A low credit score could be caused by:
- Limited credit history
- High credit card balances
- Recent credit applications
- Not being registered on the electoral roll
- Using too much of your available credit
Adverse credit usually means there are specific negative records on your credit file, such as missed payments, defaults, CCJs, IVAs, debt management plans or bankruptcy.
If your credit score is low because you have limited credit history, your options may be different from someone with recent defaults or CCJs. This is another reason why lenders look at the full credit report rather than only the score.
Does Your Deposit Affect How Important Your Credit Score Is?
Your deposit can make a difference. A larger deposit can reduce the lender’s risk because you are borrowing a smaller percentage of the property value.
If you have a smaller deposit, such as 5%, lenders may apply stricter criteria. If you have a larger deposit, you may have more options, although this does not guarantee approval.
Your credit score, deposit and affordability all work together. A strong deposit may help, but lenders will still need to be comfortable with your credit history and ability to repay the mortgage.
How To Improve Your Credit Score Before Applying For A Mortgage
The good news is that your credit score can often be improved over time. If you are planning to buy a house, it is worth reviewing your credit position as early as possible.
Steps that may help include:
- Check your credit reports: Review your information with Experian, Equifax and TransUnion.
- Correct mistakes: If anything is wrong, raise it with the credit reference agency.
- Register on the electoral roll: This can help lenders verify your address history.
- Pay bills on time: Missed or late payments can affect your credit profile.
- Reduce credit card balances: Lower credit usage can help improve how lenders view your finances.
- Avoid new credit applications: Several hard searches in a short period may make lenders cautious.
- Keep finances stable: Avoid unnecessary borrowing before a mortgage application.
- Speak to a broker early: A broker can help you understand whether you are ready to apply or whether it may be better to wait.

Should First-Time Buyers Worry About Their Credit Score?
First-time buyers often worry about their credit score, especially if they have limited borrowing history. A limited credit history does not always mean you cannot get a mortgage, but lenders may have less evidence of how you manage repayments.
If you are a first-time buyer, it can help to check your credit reports early, make sure your address history is correct and avoid taking out unnecessary credit before applying. Our first-time buyer mortgage advisers can help you understand what lenders may look for and how to prepare.

Credit Score Mortgage FAQs
What credit score is needed to buy a house in the UK?
There is no single credit score needed to buy a house in the UK. Mortgage lenders use different criteria and will usually assess your credit history alongside your income, deposit, debts, affordability and employment status.
Is there a minimum credit score for a mortgage?
There is no universal minimum credit score for a mortgage. A higher score can help, but lenders do not all use the same scoring system and may assess applications differently.
Can I get a mortgage with a fair credit score?
It may be possible to get a mortgage with a fair credit score, depending on the lender and your wider circumstances. Your deposit, income, debts and recent credit conduct can all affect the outcome.
Can I get a mortgage with a low credit score?
A low credit score can make getting a mortgage more difficult, but it does not always make it impossible. You may have fewer lender options or need a larger deposit, depending on your situation.
Do mortgage lenders use Experian, Equifax or TransUnion?
Mortgage lenders may use one or more credit reference agencies when assessing an application. Experian, Equifax and TransUnion can all hold slightly different information, so it is worth checking all three before applying.
Does applying for a mortgage affect your credit score?
A mortgage application can involve a credit search. Multiple hard searches in a short period may affect your credit profile, so it is worth getting advice before applying to several lenders.
How can I improve my credit score before applying for a mortgage?
You can improve your credit position by paying bills on time, reducing debts, checking your credit reports, correcting mistakes, registering on the electoral roll and avoiding unnecessary new credit applications before applying.
Is credit score more important than deposit?
Both matter. A larger deposit can reduce lender risk, but lenders will still review your credit history and affordability. A strong credit score does not replace the need for a suitable deposit and affordable repayments.
Can first-time buyers get a mortgage with limited credit history?
Some first-time buyers can get a mortgage with limited credit history, but lenders may need enough evidence to assess affordability and reliability. Checking your credit report and speaking to a broker early can help you prepare.
Should I speak to a broker if I am worried about my credit score?
Yes. A mortgage broker can help you understand how lenders may view your credit score and whether it is sensible to apply now or improve your position first.
