What Is a Good Credit Score in the UK? Experian, Equifax and TransUnion Explained

A good credit score in the UK means a score rated "good" or "excellent" by whichever credit reference agency a lender consults. The three main agencies are Experian, Equifax, and TransUnion, and each uses a different scale. A score of 721 on Experian is "good"; the same number on Equifax would be "excellent". What matters most is not the number itself, but what that number means on the relevant agency's scale.
Short Summary
There is no single unified credit score in the UK. Experian, Equifax, and TransUnion each calculate and display scores differently, and lenders may use any one (or a combination) of them.
Lenders do not just look at the overall score; they also examine the detail behind it, including your payment history, how much credit you are using, and whether you have any defaults or county court judgements (CCJs).
Checking your own credit score does not affect it. You can check it as often as you like through free services such as Experian, ClearScore (Equifax data), or Credit Karma (TransUnion data).
Improving your credit score is possible, but it takes time. Most negative marks fade significantly after three years and disappear entirely after six years.
What do the score bands actually mean?
Each agency rates scores across broadly similar bands: poor, fair, good, and excellent. The table below shows the numeric thresholds for each.
| Agency | Total scale | Poor | Fair | Good | Excellent |
|---|---|---|---|---|---|
| Experian | 0-999 | 0-560 | 561-720 | 721-880 | 881-999 |
| Equifax | 0-700 | 0-278 | 279-419 | 420-465 | 466-700 |
| TransUnion | 0-710 | 0-565 | 566-603 | 604-627 | 628-710 |
Falling within the "good" band gives you access to most mainstream credit products, including mortgages, personal loans, and credit cards with competitive rates. Reaching "excellent" typically unlocks the lowest available interest rates and the best rewards products.
What do lenders actually look at?
Your score is a summary, not the full picture. When you apply for credit, most lenders retrieve your full credit file, not just the headline number. They look at:
- Payment history: whether you have missed or been late with any payments
- Credit utilisation: what proportion of your available credit you are currently using
- Length of credit history: how long your oldest accounts have been open
- Types of credit: a mix of credit cards, loans, and a mortgage is viewed more favourably than relying on a single type
- Recent applications: each hard search leaves a footprint visible to other lenders for 12 months
A high score combined with a recent CCJ will often lead to a decline. Equally, a score in the "fair" band with a clean payment history over five or more years can sometimes result in approval. The score is a guide, not the final word.
How do different types of credit affect my score differently?
Not all credit products affect your score in the same way. Structured debt (personal loans, hire purchase agreements, mortgages) with a consistent repayment history generally builds your score faster than revolving credit (credit cards, overdrafts), because it demonstrates you can manage fixed monthly commitments over a long period.
Missing payments on a credit card can temporarily harm your score more than missing a utility bill payment, because credit accounts are reported to agencies monthly, while utilities reporting practices vary. However, utility and mobile phone defaults do appear on your credit file and will lower your score.
How can I improve my credit score?
These are the most effective actions, roughly in order of impact:
Register on the electoral roll at your current address. If you are not registered, lenders cannot verify who you are, which undermines every application you make. You can register at gov.uk/register-to-vote.
Pay every credit account on time, every month. Setting up direct debits for at least the minimum payment removes the risk of an accidental missed payment.
Keep your credit card balances below 30 per cent of your limit. Using £300 of a £1,000 limit is better than using £900. Paying balances in full each month is even better.
Avoid applying for multiple credit products within a short period. Each application triggers a hard search, and several in a short window signals financial stress.
Check your credit file for errors and dispute any you find. Mistakes on credit files are more common than people realise. All three agencies offer free access to your report.
How long does it take to improve a bad credit score?
Most negative information stays on your file for six years from the date of the default or event. After six years, it is removed entirely. Between years three and six, the impact of most negative marks fades gradually as the event becomes older and is outweighed by more recent positive behaviour.
Building a good score from scratch (for example, if you have no credit history at all) typically takes 12 to 24 months of responsible credit use. A credit builder card from a provider such as Aqua, Vanquis, or Capital One can help establish a record if used carefully and cleared in full each month.
FAQ
What credit score do I need for a mortgage?
Most high-street mortgage lenders, including Halifax, Nationwide, and Barclays, prefer applicants in the "good" or "excellent" band. A score in the "fair" band does not automatically mean rejection, but it reduces your options and may result in a higher interest rate. Specialist lenders can consider applicants with adverse credit histories, though rates are typically higher.
Does checking my own credit score harm it?
No. Checking your own score generates a "soft search", which is only visible to you. Only a "hard search", triggered when you formally apply for credit, is visible to lenders and can affect your score. You can check your score as often as you like without any negative effect.
Why do I have different scores with different agencies?
Because each agency collects data independently and uses its own scoring model. Not all lenders report to all three agencies, so each file may contain slightly different information. A credit card provider might report to Experian but not TransUnion, meaning the accounts would show on one file but not the other.
Is there a universal UK credit score?
No. There is no single credit score shared across all lenders or all agencies. Each agency produces its own score and lenders use whichever agency or scoring model they have a relationship with. This is why it is worth checking your file with at least two agencies.
Can I have a good score with one agency and a poor score with another?
Yes, and it is more common than people expect. If a lender only reports to one agency, that account will only appear on one file, creating a difference between your scores. Checking all three files gives you the most complete picture.
How often does my credit score update?
Most lenders and credit card providers report to the agencies once per month, though the exact timing varies. Your score is typically recalculated each time your file is updated. Changes to your score after a positive action, such as paying down a credit card balance, usually become visible within one to two months.
