Your credit score plays a role in getting a mortgage, but it is not the only thing lenders look at. There is no single number you must hit. What matters is how your credit history fits alongside your income, deposit, and overall affordability.
This guide explains what mortgage lenders actually check, what counts as a good score, and what your options are if your score is lower.

Is there a minimum credit score for a mortgage?
There is no universal minimum credit score in the UK. Each lender sets its own criteria, and some are more flexible than others.
Instead of working to a fixed number, lenders look at your overall credit profile.
What lenders are really checking
- Your repayment history. Have you missed payments or defaulted?
- Your current borrowing. How much credit are you using?
- The length of your credit history. How long have you had accounts open?
- Your stability. This includes your address history and employment
For example, missing one mobile phone payment two years ago is very different from multiple recent missed credit card payments. Lenders look at both how recent and how serious the issue was.
Credit usage also matters. If you have a £2,000 credit card limit and regularly carry a £1,800 balance, this can be seen as higher risk, even if you make payments on time.
If you have never used credit before, this can also be a challenge. Many first-time buyers have a “thin” credit file, which means lenders have less information to assess.
What credit score do you typically need?
Although there is no fixed number, most high street lenders prefer applicants with a “good” credit score.
As a rough guide:
- Good to excellent score: access to more lenders and better rates
- Fair score: fewer options, but still possible
- Poor score: limited lenders, often higher rates
Different credit agencies score differently, so your number will vary between Experian, Equifax, and TransUnion.
What matters more is how your situation looks in practice.
For example:
- A buyer earning £45,000 with a 10 percent deposit and no missed payments will usually have a wide choice of lenders and access to more competitive rates
- A buyer earning £30,000 with a small default from three years ago may still be accepted, but might need a 10 to 15 percent deposit and could face slightly higher rates
- Someone with recent missed payments may need to use a specialist lender, often with a larger deposit and higher monthly costs
Your credit score affects the deals you can access, not just whether you are approved.
Why your credit score is only a guide
Your credit score is useful, but lenders do not use your exact number.
Each lender has its own internal scoring system. This means one lender may accept you, while another may not, even with the same credit report.
This is why speaking to a broker or checking your options early can make a difference.
Can you get a mortgage with a low credit score?
Yes, but there are usually trade-offs.
What changes if your score is low
- You may be offered higher interest rates
- You may need a larger deposit, often 15 to 25 percent
- Your choice of lenders may be more limited
When it is still possible
You are more likely to be accepted if:
- Any credit issues are older, typically over two to three years
- You have a stable income and can comfortably afford repayments
- You are borrowing a lower percentage of the property value
For example, someone with past credit issues but a 20 percent deposit and steady income may still have solid options, especially with the right lender.
How to improve your credit score before applying
Improving your credit profile can make a real difference to the deals available to you.
- Check your credit reports with all three agencies
- Make sure you are registered on the electoral roll
- Pay all bills and credit commitments on time
- Reduce credit card balances. For example, if your limit is £2,000, aim to keep the balance below £600
- Avoid making multiple credit applications close together
Some improvements can happen quite quickly. Paying down credit card balances or correcting errors on your report can help within a few months.
Other factors take longer. Older missed payments or defaults usually become less important over time, especially after a few years of clean history.

Next step: check what you could borrow
Your credit score is only one part of the picture. Lenders will also assess your income, spending, and deposit.
A good next step is to get an Agreement in Principle. This gives you an early indication of how much you could borrow and whether lenders are likely to accept you.
In many cases, this involves a soft credit check, so you can explore your options without affecting your score. It can also make you more attractive to sellers when you start viewing properties.
