A credit rating is an important basis on which banks assess lending risk. It is calculated by TransUnion (TU) and divided into grades A–J. The score affects loan interest rates, mortgage approval and immigration screening, and can be checked through official or bank channels.
Key takeaways
- Scores range from 1,000 to 4,000 and are divided into grades A–J
- The higher the rating, the lower the loan interest rate and the better the chance of mortgage and loan approval
- Late repayments, excessive credit utilisation and frequent borrowing in a short period all lower your score
- You can check your credit rating through TransUnion directly or through bank / personal finance apps
- If you find an error in your credit report, apply to TransUnion for a correction as soon as possible
What is a credit rating? Understanding the key indicators of a TU report
Definition of credit rating
A credit rating (Credit Rating, commonly known as the TU rating) is a score calculated from an individual's credit records, ranging from 1,000 to 4,000, and reflects the person's financial habits and creditworthiness.
In Hong Kong, the credit database is mainly managed by TransUnion Limited (TransUnion). When people apply for a credit card, a loan or a property mortgage, financial institutions request this TU report from TransUnion to assess lending risk. The higher the score, the better the credit quality and the lower the risk of default.
Who checks your credit rating?
Besides yourself, the following organisations may check it once authorised:
- Banks and finance companies: This is a necessary vetting step when approving credit cards, mortgages and personal loans.
- Employers: Financial institutions, law enforcement agencies and sensitive industries such as the jewellery trade may check it when recruiting, to ensure applicants' finances are stable.
- Leasing companies or landlords: Used to assess whether a tenant can pay rent on time.
- Immigration authorities: Some countries (such as the UK, Australia and Canada) require applicants to provide a credit report from their country of origin when assessing visa or immigration applications.
Credit rating grade table (A–J)
TransUnion divides credit scores into 10 grades, A to J:
| Grade | Score range | Credit standing | Banks' general attitude |
| A | 3,526 – 4,000 | Excellent | Usually enjoys the lowest annual percentage rate (APR ) on the market. |
| B | 3,417 – 3,525 | Good | Interest rates are usually quite favourable. |
| C | 3,240 – 3,416 | Fair | A high chance of approval, but the interest rate may not be the most favourable. |
| D – F | 2,883 – 3,239 | Average | Subject to strict review, with higher interest rates, or the loan limit may be reduced. |
| G – H | 2,505 – 2,882 | Poor (high risk ) | Banks are very likely to reject the application, or will only approve loans at extremely high interest rates. |
| I – J | 1,000 – 2,504 | On the verge of bankruptcy / bankrupt | Basically unable to apply for any mainstream bank loan or credit card. |
What impact does a high or low credit score have?
Your credit rating is not just a number; it has a concrete impact on real life and financial costs:
- Big differences in borrowing costs: If a Grade A and a Grade H applicant apply for the same personal loan, the annual percentage rate (APR) can differ by more than 10%. On a large loan, the interest expense can differ by tens of thousands of dollars.
- Mortgage application thresholds: If the rating is too low (for example below Grade F), the bank may require additional guarantors or even reject the mortgage outright, which directly affects your plans to buy a home.
- Job and immigration screening: A poor credit record can become an obstacle to entering certain industries or emigrating.
Which behaviours can easily affect your credit rating?
Late repayments
Credit scores are most easily affected by repayment records. If you often repay late or fail to make the minimum repayment, these records are reported to TransUnion, and if they keep accumulating they can cause the score to drop sharply.
Excessive credit utilisation
“Credit utilisation” is the proportion of your total credit limit that has been used. Even if you repay on time every month, if utilisation stays too high for a long time (close to 100%), the system will judge that you are under greater financial pressure. It is generally recommended to keep it below 30% to 50%.
Many applications in a short period
Each time you apply to a bank for a credit card or loan, the bank makes a “hard inquiry” with TransUnion. If several inquiries appear in a short time, the system may interpret this as rising financial pressure, causing the credit score to fall.
Too short a credit history or account management errors
Having a credit card that you have used for many years with a good repayment record is more helpful for building a high score than having no borrowing record at all (commonly known as Clean Credit). A lack of credit history makes it difficult for banks to fully assess risk, so the score is usually lower.
How do Hong Kong people check their credit record? 2 ways to look up your credit rating
Method 1: Official enquiry from TransUnion
An official enquiry is the way to obtain the most complete credit report. You can subscribe to the credit report and monitoring service on the TransUnion website or mobile app.
- Features: A detailed report, including past repayment records, inquiry records and score trends.
- Fee: A monthly fee is usually payable (about HK$280, depending on the promotions at the time).
Method 2: Bank or third-party personal finance apps
Some banks and personal finance platforms offer a credit rating enquiry service, so you can quickly keep track of your credit position.
- Features: Free, quick and convenient, suitable for everyday monitoring.
- Note: Data may be delayed or only some indicators may be provided.
Want to improve your credit score? Avoid these pitfalls first
Repay on time and lower your credit utilisation
To avoid late repayments, you can set up automatic transfers (Autopay) to help ensure on-time repayment. If funds allow, it is best to pay in full (Full Pay) before the statement due date, since paying only the minimum amount (Min Pay) may have a negative effect on your credit score.
Avoid over-applying for credit in a short period
In the 3-6 months before formally applying for a mortgage or large loan, try to avoid applying for new credit cards or personal loans, to reduce the number of “hard inquiry” records and protect the stability of your credit rating.
Check your report regularly and correct errors
Credit reports sometimes contain errors, for example a cancelled credit card that still shows as active, or an account used fraudulently by someone else. It is advisable to review your credit report regularly and, if you find anything unusual, to ask TransUnion to correct it immediately, to avoid an unnecessary drop in your score.
FAQ
What is a normal credit score for most people?
Generally speaking, Grade C or above is an acceptable level, and you can apply for most bank products. If you can stay at Grade A or B, you can be more confident of obtaining the most favourable rates on the market.
Does checking my own credit rating lower my score?
No. Checking your own report through TransUnion or a bank app counts as a “soft inquiry”, and no matter how many times you check, it does not affect your score.
How do I correct errors found in my credit report?
If you find that information is wrong, you need to contact TransUnion directly and provide relevant supporting documents (such as a bank settlement certificate). TransUnion will correct the information after verification, a process that usually takes several weeks.
How long are bad records or bankruptcy data kept on the report?
Ordinary negative records are generally kept for 5-7 years, while bankruptcy data is kept for 8 years as required by law, but the specific details are still subject to TransUnion and the relevant laws.
Will cancelling an unused credit card affect my rating?
Cancelling a credit card may slightly change your credit utilisation ratio, but its impact on your credit rating is usually small; what matters is still your overall credit management.
