If you’re buying your first home, your credit score can feel like one of the biggest unknowns.
You may have checked Experian, ClearScore, Credit Karma or another credit app and seen a number, but that number doesn’t tell you everything. A good score can help, but there is no single credit score you need for a mortgage in the UK.
Mortgage lenders look at your wider situation, including your income, deposit, debts, spending, credit history and whether the mortgage looks affordable. Your score matters, but it’s only one part of the decision.
Quick answer: there is no fixed minimum credit score for a mortgage in the UK. As a first-time buyer, you may still be able to get a mortgage with a fair or lower score, depending on your income, deposit, affordability and the detail behind your credit report.

Is there a minimum credit score for a mortgage in the UK?
No, there isn’t a universal minimum credit score for a mortgage in the UK.
Each lender has its own criteria. One lender may accept your application, while another may decline it, even if they’re looking at the same credit report.
This is why your credit score should be treated as a guide, not a pass or fail mark.
Lenders usually look at the details behind your score, such as:
- Whether you’ve missed payments
- Whether you’ve had defaults or CCJs
- How recent any credit issues were
- How much credit you’re currently using
- Whether you’re registered on the electoral roll
- How long you’ve lived at your current address
- How much debt you already have
- Whether your mortgage payments look affordable
For first-time buyers, this can be reassuring. You don’t need to hit one exact number before you’re allowed to apply. What matters is how your credit profile fits with the rest of your mortgage application.
What credit score do first-time buyers need for a mortgage?
First-time buyers usually have better mortgage options with a good or excellent credit score, but that doesn’t mean you need a perfect score.
As a rough guide:
| Credit profile | What it may mean for a first-time buyer mortgage |
|---|---|
| Excellent credit | Wider lender choice and potentially stronger rates |
| Good credit | Usually a solid range of mortgage options |
| Fair credit | Still possible, but lender choice may be narrower |
| Poor credit | More limited options and possibly higher rates |
| Very poor credit | Specialist lender route may be needed |
A first-time buyer with a fair credit score, steady income and a 10% or 15% deposit may still have options. A buyer with a higher score but lots of existing debt may find their borrowing is more limited.
This is because lenders aren’t just asking, “What is your score?” They’re asking, “Can this person afford the mortgage, and does their credit history suggest they’re likely to keep up with the repayments?”
That’s why your credit score should be considered alongside how much you can borrow as a first-time buyer, your deposit and your monthly budget.
Why your credit score can look different on different apps
Many first-time buyers check their credit score through free apps before applying for a mortgage. This is useful, but it can also be confusing because different apps may show different numbers.
That’s because the main UK credit reference agencies use different scoring systems.
| Credit reference agency | Common score range | What to remember |
| Experian | Up to 999 | One of the best-known UK credit score ranges |
| Equifax | Scale can vary depending on product or provider | Check the score range shown in your own report |
| TransUnion | Up to 710 | Often shown through services such as Credit Karma |
This means a score of 700 may look strong on one scale but less impressive on another.
Mortgage lenders may use data from Experian, Equifax, TransUnion or their own internal scoring systems. They don’t simply copy the consumer score you see in an app.
The detail in your credit report is usually more important than the number itself. Missed payments, defaults, high credit card balances and recent hard searches can all affect how a lender views your application.
Why lenders don’t just use your credit score
Your credit score is important, but mortgage lenders need to look at the full picture.
As a first-time buyer, they’ll usually assess:
- Your income
- Your deposit
- Your existing debts
- Your regular spending
- Your bank statements
- Your employment type
- Your credit history
- The property you want to buy
- The loan-to-value of the mortgage
- Whether the mortgage remains affordable if rates change
This is why a high credit score doesn’t automatically mean you’ll get approved. If the mortgage is too large for your income, or your bank statements show regular financial pressure, a lender may still say no.
It also works the other way. A lower credit score doesn’t always mean you can’t get a mortgage. If your income is stable, your deposit is strong and any credit issues are minor or historic, you may still be able to buy your first home.
A mortgage affordability calculator can help you get an early sense of how income, deposit and borrowing fit together before you apply.
What mortgage lenders check as well as your credit score
When you apply for a mortgage, lenders usually assess several areas together.
1. Your income
Lenders want to know how much you earn and how reliable that income is.
If you’re employed, this usually means payslips and bank statements. If you’re self-employed, you may need tax calculations, tax year overviews, accounts or business bank statements.
For self-employed first-time buyers, the way mortgage lenders calculate self-employed income can vary depending on whether you’re a sole trader, contractor, partner or limited company director.
2. Your deposit
Your deposit affects how much risk the lender is taking.
A larger deposit means you’re borrowing a smaller percentage of the property value. This can improve your options, especially if your credit score is fair or your credit history is limited.
For example, a first-time buyer with a 5% deposit and fair credit may have fewer lender options than someone with a 10% or 15% deposit. That doesn’t mean a 5% deposit is impossible, but it can make lender choice more important.
This is why the amount of deposit you need for a mortgage can depend on your wider application, not just the property price.
3. Your debts
Existing debts can reduce the amount you’re able to borrow.
Lenders may look at:
- Credit cards
- Personal loans
- Car finance
- Overdrafts
- Buy now, pay later commitments
- Student loan repayments
- Other regular credit commitments
Even if you’ve never missed a payment, large debts can affect affordability.
4. Your bank statements
Lenders may review your bank statements to understand your income, spending and account conduct.
They may look for:
- Regular income
- Overdraft use
- Returned payments
- Gambling transactions
- Large unexplained payments
- Existing credit commitments
They’re not usually expecting perfect spending habits. They’re looking for signs that the mortgage is affordable and sustainable.
5. Your address history
A stable address history can help lenders verify your identity and assess your credit profile.
If you’ve moved frequently, make sure your addresses are consistent across your bank accounts, credit accounts and credit reports.
Being registered on the electoral roll can also help.
Can first-time buyers get a mortgage with a fair credit score?
Yes, first-time buyers can get a mortgage with a fair credit score.
A fair score may reduce the number of lenders available, but it doesn’t automatically stop you from getting a mortgage.
Your options will depend on why your score is fair.
For example, your score may be fair because:
- You have a short credit history
- You’ve never borrowed much before
- You’ve recently moved house
- You’re not on the electoral roll
- You’re using a high percentage of your credit card limit
- You’ve made several recent credit applications
- You had a minor missed payment a few years ago
Some of these issues are easier to improve than others.
A thin credit file is common for first-time buyers, especially if you’ve never had a credit card, loan or finance agreement. This can make it harder for lenders to judge how you manage borrowing, but it isn’t the same as having bad credit.
Can first-time buyers get a mortgage with a low credit score?
Yes, it can be possible to get a first-time buyer mortgage with a low credit score, but your options may be more limited.
You may find that:
- Fewer lenders are available
- Interest rates are higher
- A larger deposit may be needed
- The lender asks more questions
- A specialist lender may be more suitable
A low score is usually more of a concern when it reflects recent or serious credit issues.
For example, recent missed payments, defaults or CCJs are likely to have a bigger impact than a limited credit history or an old issue that has already been settled.
If your score is low, it’s usually better to understand your options before making applications. Applying to unsuitable lenders can waste time and may add unnecessary hard searches to your credit file.
For buyers with more serious credit issues, adverse credit mortgage advice may be useful before deciding whether to apply now or wait.
Is a low credit score the same as bad credit?
A low credit score and bad credit are not always the same thing.
This is especially important for first-time buyers.
You may have a low score because:
- You’ve never used much credit
- Your credit history is short
- You’ve recently moved
- You’re not on the electoral roll
- You have high credit card utilisation
- Your details don’t match across accounts
That’s different from having adverse credit.
Adverse credit usually means there are specific negative marks on your report, such as:
- Missed payments
- Defaults
- County Court Judgments
- Debt management plans
- Individual Voluntary Arrangements
- Bankruptcy
- Repossessions
A first-time buyer with a limited credit history may be viewed very differently from someone with a recent default or CCJ. Both may have a lower score, but the lender’s view of the risk may not be the same.
This is why it’s important to look beyond the score and understand what is actually on your credit report.
Example first-time buyer mortgage scenarios
Here are some simplified examples of how credit score and credit history can affect a first-time buyer mortgage application.
| First-time buyer situation | Likely impact | What may help |
| Good credit, stable income, 10% deposit | Usually a wider choice of lenders | Compare deals and avoid new credit before applying |
| Fair credit, no missed payments, 5% deposit | Possible, but lender choice may be narrower | Check affordability and strengthen your profile where possible |
| Low score due to limited credit history | Not always a major issue | Electoral roll, stable address history and sensible credit use |
| High credit card balances | May reduce borrowing or lender choice | Paying balances down before applying |
| Old missed payment | May still be accepted | Clean recent history and the right lender |
| Recent default or CCJ | More difficult | Larger deposit, specialist lender and advice before applying |
These examples are not fixed rules. Mortgage decisions depend on your full situation.
A first-time buyer with a small deposit and recent missed payments may have fewer options than someone with a larger deposit and older credit issues. Timing, deposit size, affordability and lender choice all matter.
How to improve your credit score before applying for your first mortgage
If you’re not ready to apply yet, improving your credit profile can make your first mortgage application stronger.
Start with the basics:
- Check your credit reports with Experian, Equifax and TransUnion
- Correct any errors as early as possible
- Register on the electoral roll
- Pay all bills and credit commitments on time
- Reduce credit card balances
- Avoid using your overdraft where possible
- Avoid multiple credit applications before applying
- Keep older well-managed accounts open if they help your credit history
- Make sure your address history is consistent across accounts
Credit utilisation is especially important.
For example, if you have a credit card with a £2,000 limit and regularly carry a £1,800 balance, this may make you look more financially stretched. Reducing that balance could improve your credit profile and may also help affordability.
Some improvements can happen within a few months, such as correcting errors or reducing card balances. Other issues take longer. Missed payments and defaults usually become less important over time, especially if your recent history is clean.
If you’re planning to buy in the next six to twelve months, building a practical plan to improve your credit score before a mortgage can help you avoid last-minute problems.
Should first-time buyers get an Agreement in Principle?
An Agreement in Principle can be useful when you’re starting to take your first home seriously.
It gives you an early indication of how much a lender may be willing to lend and whether your application is likely to fit their criteria.
In many cases, an Agreement in Principle uses a soft credit check. That means it shouldn’t affect your credit score. However, not every lender works in the same way, so it’s worth checking whether a soft or hard search will be used.
An Agreement in Principle can be helpful if:
- You’re starting to view properties
- You want to understand your budget
- You’re worried about your credit score
- You’ve had past credit issues
- You want to avoid applying to unsuitable lenders
- You want to show estate agents you’re a serious buyer
It isn’t a full mortgage offer, but it can be a useful step before making an offer on a property.
When should first-time buyers speak to a mortgage broker?
You may not need specialist help if your credit is strong, your income is straightforward and your deposit is healthy.
However, many first-time buyers find the process easier with support, especially when credit score, deposit and affordability all need to be considered together.
A broker may be useful if:
- You’re unsure whether your credit score is good enough
- You have a fair or low credit score
- You have a small deposit
- You’ve had missed payments
- You have a default or CCJ
- You’re self-employed
- You’ve already been declined
- You’re worried about choosing the wrong lender
The right lender can make a big difference. This is especially true for first-time buyer mortgages, where small differences in deposit, income, credit history and affordability can affect which lenders are suitable.
If your credit report shows more serious issues, such as recent defaults or CCJs, adverse credit mortgages may be more relevant than a standard high street mortgage route.
Next step: check what you could borrow
Your credit score is only one part of getting your first mortgage. Lenders will also look at your income, deposit, debts and affordability.
If you’re still working out what you can afford, a mortgage affordability calculator can help you estimate how much you may be able to borrow.
A mortgage repayment calculator can then help you understand how different mortgage sizes, rates and terms could affect your monthly payments.
Once you have a clearer idea of your budget, an Agreement in Principle can help you move from planning to viewing properties with more confidence.

Frequently asked questions
What is the minimum credit score for a mortgage in the UK?
There is no fixed minimum credit score for a mortgage in the UK. Each lender has its own criteria, and your credit score is only one part of the decision. Lenders also look at your income, deposit, debts and affordability.
What credit score do I need for a mortgage as a first-time buyer?
There isn’t one specific credit score you need as a first-time buyer. A good or excellent score can improve your options, but buyers with fair or lower scores may still be accepted depending on their deposit, income, affordability and credit history.
Can first-time buyers get a mortgage with a fair credit score?
Yes, first-time buyers may be able to get a mortgage with a fair credit score. Your options will depend on why the score is fair, how much deposit you have and whether there are any serious credit issues on your report.
Can first-time buyers get a mortgage with a low credit score?
Yes, but lender choice may be more limited. You may need a larger deposit, and the rates available may be higher. If your low score is linked to recent missed payments, defaults or CCJs, specialist lender options may be more relevant.
Does a higher credit score guarantee a mortgage?
No. A higher credit score can help, but it doesn’t guarantee approval. Lenders also assess your income, deposit, debts, spending and the property you want to buy.
Which credit score do mortgage lenders use?
Mortgage lenders may use data from Experian, Equifax, TransUnion or a combination of credit reference agencies. They may also use their own internal scoring system rather than relying only on the consumer score you see in an app.
Why is my credit score different on different sites?
Credit scores can differ because each credit reference agency uses its own scoring system, data and score range. The number may vary between Experian, Equifax, ClearScore and Credit Karma.
Can I get a mortgage if I’ve never had credit?
Yes, it may still be possible, but a limited credit history can make it harder for lenders to assess you. This is common for some first-time buyers. Registering on the electoral roll, keeping address details consistent and building a small amount of well-managed credit may help.
Can I get a mortgage with missed payments?
Yes, depending on how recent and serious the missed payments were. Older, isolated missed payments are usually less of an issue than multiple recent missed payments.
Can I get a mortgage with a default?
It may be possible to get a mortgage with a default, especially if it is older, settled and the rest of your application is strong. Recent defaults are likely to limit your options more.
Can I get a mortgage with a CCJ?
It can be possible to get a mortgage with a CCJ, but it depends on the amount, date, whether it has been satisfied and the rest of your circumstances. A specialist lender may be needed.
Does checking my credit score affect my mortgage chances?
No. Checking your own credit score usually creates a soft search, which does not affect your score or your mortgage chances.
Does an Agreement in Principle affect my credit score?
Many Agreements in Principle use a soft credit check, but not all lenders work in the same way. It’s worth checking whether the lender or broker will use a soft or hard search before proceeding.
Should I pay off credit cards before applying for a mortgage?
Reducing credit card balances can help your mortgage application, especially if you’re using a high percentage of your available credit. However, it’s worth considering your wider finances too, including your deposit and emergency savings.
How long before applying for a mortgage should I check my credit report?
Ideally, check your credit reports at least three to six months before applying. This gives you time to correct errors, reduce balances and avoid unnecessary credit applications.
