How Credit Scores Work
The mechanics behind your UK rating
Data Collection
Credit Reference Agencies (CRAs) like Experian, Equifax, and TransUnion gather data from lenders, the electoral roll, and public records.
Algorithmic Scoring
Each CRA uses its own proprietary algorithm to weigh factors like payment history, credit utilisation, and length of credit history.
Lender Decisions
When you apply for credit, lenders check your score and report to decide whether to approve you and at what interest rate.
Continuous Updates
Your score is not static. It updates monthly as new data is reported, meaning positive financial habits will gradually improve your rating.
UK Credit Score Ranges by Agency
Each of the three main UK Credit Reference Agencies uses a different scoring scale. Here is how your score is typically categorised.
| Rating | Experian (0-999) | Equifax (0-1000) | TransUnion (0-710) |
|---|---|---|---|
| Excellent | 881 – 999 | 811 – 1000 | 604 – 710 |
| Good | 721 – 880 | 661 – 810 | 566 – 603 |
| Fair | 561 – 720 | 421 – 660 | 551 – 565 |
| Poor | 0 – 560 | 0 – 420 | 0 – 550 |
| Key Factors | Payment history, credit utilisation, electoral roll registration, financial associations, and recent credit applications. | ||
Credit Score FAQ
Answers to the most frequently asked questions about UK credit scores, improving your rating, and understanding credit reports.
A ‘good’ credit score varies by agency. For Experian (0-999), a good score is 721-880. For Equifax (0-1000), it is 661-810. For TransUnion (0-710), a good score is 566-603. Scores above these ranges are considered ‘Excellent’ and will help you secure the best interest rates.
No. Checking your own credit report or score is known as a ‘soft search’ or ‘soft footprint’. It is visible only to you and has absolutely no impact on your credit score. Only ‘hard searches’ initiated by lenders when you apply for credit affect your score.
To improve your score quickly, ensure you are registered on the electoral roll, pay all bills on time, reduce your credit utilisation to below 30% of your available limit, and avoid applying for multiple new credit accounts in a short period.
Most negative marks, such as missed payments, defaults, County Court Judgments (CCJs), and bankruptcies, remain on your UK credit report for 6 years from the date of the incident, even if you pay them off earlier. However, paying them off is still better than leaving them outstanding.
