What credit score do you need for a mortgage? (2026 guide)
What credit score do you need for a mortgage?
There is no single “minimum” credit score required for a mortgage. Lenders have varying criteria, and approval is not based solely on your credit score. However, a higher score increases your options and improves the terms you are likely to receive.
Think of your credit score as a risk indicator rather than a pass or fail test. Lenders use it to estimate your likelihood of repaying the loan. A higher score suggests reliability and consistency. A lower score raises questions — which lenders address by imposing stricter terms, higher rates, or additional requirements.
In practice, this means two things:
- You may be approved even if your score is not perfect.
- However, your mortgage will likely come with higher costs.
So the real question is not whether you can get a mortgage, but on what terms it will be offered.
What is a credit score, and how does it work?
A credit score is a numerical assessment of your reliability as a borrower. It is based on your financial history and allows lenders to quickly assess risk before reviewing your full application.
Several key factors typically determine your score:
- Payment history (whether you pay on time)
- Total debt and credit utilisation
- Length of credit history
- Types of credit used
- Recent credit applications
Consistent financial behavior improves your score, while missed payments and high debt can reduce it. There is no single universal score. In the UK, agencies such as Experian, Equifax, and TransUnion each calculate their own version, so your score may vary depending on the agency.
What is considered a good credit score for a mortgage?
There’s no universal definition of a “good” credit score — it depends on the scoring system used by the lender. In the UK, one of the most commonly referenced scales is Experian. As a general guide:
| Rating | Score (Experian) | Mortgage chances |
|---|---|---|
| Excellent | 1121–1250 | Best deals |
| Very Good | 1001–1120 | Strong options |
| Good | 861–1000 | Good chances |
| Fair | 641–860 | Limited options |
| Poor | 0–640 | Difficult |
Different credit agencies use different scoring ranges, and lenders don’t rely on a single number. A “good” score in one system doesn’t guarantee approval, just as a lower score doesn’t automatically mean rejection.
In practice, your credit score serves as a positioning tool. A higher score increases your options and access to better rates, but it is only one factor in the decision.
Ask a mortgage expert a question and get a professional answer
Can you get a mortgage with a low credit score?
Yes, but your options will be more limited. With a lower credit score, fewer lenders are willing to take the risk. Those who do typically offer less favorable terms, including higher interest rates or stricter requirements.
You may need a larger deposit to offset the perceived risk, which reassures the lender that you have a financial buffer.
Specialist or “subprime” lenders may work with borrowers who have weaker credit profiles. These applications are often assessed manually rather than relying solely on automated scoring.
The key takeaway is that a low credit score does not automatically exclude you, but it affects the types of mortgages available and the cost of borrowing.
Why your credit score isn’t the only thing that matters
Your credit score is important, but it is only one factor in the decision process. Lenders consider your entire financial profile, including income, regular expenses, deposit size, and financial stability, rather than focusing on a single number.
You may have a strong credit score and still be declined if your income does not support the loan or if your expenses are too high. Conversely, some borrowers with weaker credit histories are approved when other factors offset the risk.
What can negatively affect your credit score?
Several factors can lower your credit score, and most are immediately visible to lenders:
- Missed or late payments are among the strongest negative indicators.
- High levels of debt, especially when using a large portion of your available credit.
- Frequent credit applications may indicate financial stress.
- Defaults or CCJs are serious red flags that remain on your record for years.
These factors not only lower your score but also influence how lenders assess your reliability as a borrower.
Does applying for a mortgage affect your credit score?
Yes, but typically only in the short term. When you apply for a mortgage, the lender performs a hard credit check. This leaves a visible mark on your credit report and may slightly reduce your score for a period of time.
This is normal and expected. A single application is unlikely to have a significant impact. Problems can occur if you submit multiple applications within a short period of time. This may signal risk to lenders and lower your score more noticeably.
In practice, the effect is temporary. As long as you apply strategically instead of repeatedly, your credit score should recover quickly.
How to improve your credit score before applying
If your credit score is lower than desired, consider these practical steps to improve it before applying for a mortgage:
- Pay all bills on time → consistency is the strongest positive signal
- Reduce existing debt → especially high credit card balances.
- Avoid multiple applications → limit new credit in the short term.
- Register on the electoral roll → helps lenders verify your identity.
- Check your credit report → fix errors that may be affecting your score.

While these steps will not improve your score overnight, even small changes can increase your chances of approval and help you secure better mortgage terms.
How to check your credit score
Before applying for a mortgage, ensure you understand your current credit position. In the UK, you can check your credit score through the main credit reference agencies:
- Experian
- Equifax
- TransUnion
Each agency uses its own scoring system, so your score may vary between them. This is expected. Most services provide free access, with optional paid upgrades. Checking your own score does not affect it; this is called a “soft check.”
Reviewing your credit report is more important than knowing your score. This helps you identify errors, understand factors affecting your rating, and address potential concerns for lenders.
How a credit score affects mortgage rates
Your credit score typically provides an indication of the interest rate you’re likely to be offered. Lenders use your credit score to assess risk. A higher score indicates reliability, making you eligible for lower rates and better mortgage options. A lower score signals higher risk, resulting in higher interest rates and stricter terms.
The impact can be substantial. Even a slight increase in your interest rate over a long-term mortgage can significantly raise your total borrowing costs.
In practice, your credit score affects not only approval but also the long-term cost of your mortgage.
Getting a mortgage with bad credit — what to expect
Getting a mortgage with bad credit is possible, but the terms will usually be less favourable than you might initially expect. Lenders will treat the application as higher risk, which typically results in:
| Higher interest rates | More expensive borrowing |
| Larger deposit requirements | Often needed to offset risk |
| Fewer lender options | Mainly specialist or niche providers |
In some cases, applications are reviewed manually rather than relying on automated scoring. This can work in your favour if your overall financial situation is strong. The key point is that approval is still possible, but you will be trading access for higher costs and reduced flexibility.
What lenders actually look at (beyond your credit score)
Your credit score is just one piece of the puzzle. When reviewing your application, lenders evaluate your complete financial profile:
- Income stability: regular and reliable earnings.
- Employment history: consistency is valued more than job level.
- Deposit size: a larger deposit reduces risk and may improve your loan terms.
- Spending habits: how much of your income is already allocated to existing expenses.
These factors often carry as much weight as your credit score, and in some cases, may be even more important. A strong profile in these areas can offset a lower credit score, while weaknesses may result in rejection even if your credit rating is good.
