How Your Credit Score Affects Your Mortgage Approval
When buying a property, securing a mortgage is often a critical step. But did you know that your credit score plays a huge role in whether you get approved and what rates you’ll be offered? In the UK, lenders use your creditworthiness to decide if you’re a reliable borrower. This blog will help you understand how your credit score impacts mortgage approval and how to improve it.

What Is a Credit Score?
A credit score is a numerical summary of your credit history, reflecting your ability to repay borrowed money. It’s calculated by credit reference agencies like Experian, Equifax, and TransUnion, based on data from your financial behaviour, such as:
- Your history of repaying debts (loans, credit cards, overdrafts)
- Existing debts and credit limits
- Length of credit history
- Recent credit applications
- Public records like County Court Judgements (CCJs) or bankruptcies
In the UK, credit scores generally range from 0 to 999 (or similar scales depending on the agency). A higher score indicates better creditworthiness.
Why Lenders Care About Your Credit Score
Mortgage lenders want to minimise their risk. A strong credit score signals you are responsible with credit, making you a lower risk for default. Conversely, a poor credit score raises red flags about missed payments, defaults, or financial instability.
Lenders use your credit score to decide:
- Whether to approve your mortgage application
- How much they are willing to lend
- What interest rate and mortgage terms to offer
How Credit Score Categories Affect Mortgage Approval
Broadly, credit scores fall into categories like:
| Credit Score Range | Typical Label | Impact on Mortgage |
|---|---|---|
| 800+ | Excellent | More likely to get approved with best rates |
| 700–799 | Good | High chance of approval with competitive rates |
| 600–699 | Fair | Possible approval but at higher interest rates |
| 500–599 | Poor | Approval less likely; higher rates if approved |
| Below 500 | Very Poor | Usually declined or require specialist lenders |
Note: Different lenders have varying criteria, but the pattern generally holds.
Impact of a Low Credit Score on Your Mortgage
If your credit score is low, you might face:
- Mortgage application refusals
- Higher interest rates, increasing overall cost
- Higher deposit requirements (sometimes up to 20-30%)
- Limited mortgage product options
- Need to use specialist or subprime lenders, who charge more
This can make buying a home more difficult and expensive.
