What Is a Credit Score?

How Credit Scores Are Calculated

Credit scores are based on your financial behaviour, including:

• Payment history – paying bills and loans on time

• Outstanding debts – credit card balances, loans, and overdrafts

• Credit applications – frequent applications may lower your score

• Length of credit history – longer history is generally better

• Types of credit – a mix of credit accounts can be positive

Typical Credit Score Ranges in the UK

While scoring systems vary slightly by agency:

• Excellent: 961–999 (Experian)

• Good: 881–960

• Fair: 721–880

• Poor: 561–720

• Very Poor: 0–560

Lenders generally prefer borrowers in the “Good” or “Excellent” ranges, but “Fair” scores may still be acceptable depending on circumstances.

Minimum Credit Score Needed to Buy a House

The credit score needed to buy a house depends on the type of mortgage:

Standard Mortgages

• Minimum credit score: ~620–650

• Higher scores may secure better interest rates and lower deposits

Government-Backed Schemes

• Help to Buy or Shared Ownership schemes may accept slightly lower scores (~580–600)

• Lenders often combine credit score with other factors like income, deposit size, and employment history

High-Value or Buy-to-Let Mortgages

• Minimum credit score: ~700–720

• Lenders require stronger credit profiles due to higher financial risk

How Credit Score Affects Mortgage Offers

Credit score influences multiple aspects of mortgage approval:

1. Interest Rate – Higher scores often receive lower rates, saving thousands over the mortgage term.

2. Deposit Requirement – Lower scores may require larger deposits (15–25% rather than 5–10%).

3. Mortgage Approval – Very low scores can result in rejection.

4. Loan-to-Value Ratio (LTV) – Higher scores allow higher LTVs, meaning smaller deposits.

Example:

• Buying a £350,000 property with a 5% deposit (£17,500):

  • Excellent credit → interest rate 4.0%

  • Fair credit → interest rate 5.2%

  • Poor credit → may require 20% deposit (£70,000) to secure mortgage

Checking Your Credit Score

Before applying for a mortgage, check your credit score from all three major agencies:

• Experian: Offers free and paid credit reports

• Equifax: Provides online reports with credit factors

• TransUnion: Used by some lenders to assess applications

Checking your score allows you to identify errors or areas for improvement before applying.

How to Improve Your Credit Score Before Buying a House

1. Pay Bills On Time

• Late payments negatively affect credit scores

• Set up direct debits to avoid missed payments

2. Reduce Outstanding Debts

• Pay down credit cards and loans

• Avoid taking new debts before applying

3. Check for Errors

• Mistakes on credit reports can lower scores

• Dispute inaccuracies with the credit reference agency

4. Avoid Frequent Credit Applications

• Each application leaves a “hard enquiry” on your report

• Space applications to reduce negative impact

5. Keep Credit Accounts Open

• Older accounts improve credit history length

• Avoid closing long-standing accounts unnecessarily

Common Misconceptions About Credit Scores and Mortgages

• “I need perfect credit to buy a house” – False; many lenders accept scores in the 620–650 range.

• “Checking my score lowers it” – False; checking your own score is a “soft enquiry” and does not impact your rating.

• “Debt hurts credit score permanently” – False; timely payments and reduced balances improve your score over time.

Credit Score and Deposit Size

There is a direct relationship between credit score and deposit:

• Higher credit score → lower deposit required

• Lower credit score → higher deposit required

Lenders offset risk of low credit with larger deposits. This is why improving your score before buying a house can save tens of thousands.

Using a Mortgage Broker

Mortgage brokers can help buyers with less-than-perfect credit:

• They know lenders who accept lower scores

• Help negotiate better rates or smaller deposits

• Provide guidance on improving eligibility

Practical Example: First-Time Buyer

• Property price: £300,000

• Deposit: 10% (£30,000)

• Credit score: 640 (Fair)

Outcome: Lender approves mortgage but interest rate slightly higher than someone with excellent credit. By improving score to 720 before application, buyer could reduce interest rate by 1%, saving thousands over 25 years.

Conclusion

Knowing What Credit Score Is Needed to Buy a House is crucial for budgeting, mortgage approval, and long-term affordability. In the UK, most lenders prefer scores of 620 and above, but first-time buyers and government-backed schemes may accept slightly lower scores.
