What is a Good Credit Score for a Mortgage?

Why is Good Credit important

Medical staff face extra challenges when building credit:

  • Training salaries that change often
  • Moving between hospitals frequently
  • Long working hours make managing finances harder

Good credit helps you:

  • Get approved for mortgages easier
  • Access lower interest rates
  • Save thousands on mortgage costs
  • Have more lender choices
  • Qualify for larger loan amounts

These challenges make good credit even more important.

Your Credit Score Explained

UK credit scores work differently for each company:

  • Experian: 0-999 (Excellent: 961+, Good: 881-960)
  • Equifax: 0-700 (Excellent: 466+, Good: 420-465)
  • TransUnion: 0-710 (Excellent: 628+, Good: 604-627)

Each mortgage lender has its own method of credit checking – some will look at just one of these systems, some will look at a combination. Some aren’t concerned about your score at all but rather your credit history and general credit conduct.

What Lenders See on Your Credit Report

Your credit report shows lenders how you handle money. It includes:

  • Your credit score
  • All credit accounts (cards, loans, overdrafts)
  • Payment history and late payments
  • County court judgments (CCJs)
  • How much credit you use vs. your limits
  • Credit applications you've made

Lenders use this to decide if you're safe to lend to. Bad marks like late payments or CCJs make mortgages harder to get.

Check your report often. Fix mistakes quickly. Keep it clean and accurate for better mortgage chances.

Common Mistakes to Avoid

1. Waiting Too Long Start building credit during training. Don’t wait until you need a mortgage.

2. Missing Payments One missed payment hurts your score. Set up direct debits.

3. Never Checking Your File Check for mistakes. Fix them before applying for mortgages.

4. Avoiding All Credit You need some credit to show you can manage it.

Avoiding these mistakes helps prevent credit issues that could impact your ability to get a mortgage.

Simple Steps to Build Credit

Step 1: Check Your Credit File

Get free reports from all three companies. Look for:

  • Wrong details
  • Unknown accounts
  • Incorrect payments
  • Old addresses

If you find a mistake, contact the company that reported the incorrect information to fix it straight away.

Step 2: Register to Vote

Sign up at your current address by registering on the electoral register, also known as the electoral roll. Being listed, helps lenders verify your address and residency history, which can improve your credit score and enhance your creditworthiness.

Step 3: Get Your First Credit Card

For students: Get a student credit card  

For others: Try a credit builder card

Use it for small purchases. Pay it off each month. Never use more than 30% of your limit.

Step 4: Pay Bills on Time

Set up direct debits for:

  • Phone bill
  • Utilities
  • Credit card
  • Student loan

Already Have Bad Credit? You Can Fix It

Don't worry if your credit score is already poor. You can improve it.

First, check your credit report. Look for what's hurting your score:

  • Late payments
  • High debt levels
  • Mistakes on your file
How to improve bad credit:
  • Pay all bills on time from now on
  • Pay down existing debts
  • Don't apply for new credit often
  • Fix any mistakes on your report
  • Be patient - improvements take time

Get help if you need it: Talk to a mortgage broker who understands medical careers. They can give you personal advice and help you plan your next steps.

Remember: bad credit isn't forever. With good habits, you can rebuild your score and get better mortgage deals later.

How Long Does It Take?

Month 1: Get credit reports, fix mistakes, register to vote

Months 2-6: Use credit card, pay bills on time

Months 6-12: Build steady payment history

12+ Months: Good credit score, ready for better mortgage deals

There is no minimum credit score or specific credit score needed for getting a mortgage, as requirements vary by lender.  

While a higher credit score can improve your chances, each lender has different criteria and there isn't a fixed minimum credit score needed.  

How much deposit you need can also depend on your credit score, property value, and the lender's terms. Getting a mortgage involves more than just your credit score—lenders work by assessing your full financial situation, including your income, debts, and overall affordability.

Quick Tips

  • Start early (even as a student)
  • Pay everything on time
  • Check credit score monthly  
  • Keep credit card balances low
  • Don’t apply for lots of credit at once
  • Seek expert advice from a mortgage broker if you have a low credit score or a complex financial situation
  • Be patient - good credit takes time

Your medical career will pay well later. Good credit now means better mortgage deals when you’re ready to buy.
