Your credit score affects whether you can borrow and how much interest you pay. It can also matter when you rent a home or, for some roles in some countries, when employers carry out background checks. This guide explains how credit scores work, how to check your credit report for free and the habits that improve your score over time.

Note: Credit systems differ by country. This guide focuses on the general principles and on the US system, with notes for other countries.
Credit Report vs Credit Score
- Credit report: a record of your borrowing and repayment history, held by credit reporting agencies (also called credit bureaus or credit reference agencies).
- Credit score: a number calculated from your report that estimates how likely you are to repay. Different lenders and scoring models produce different scores.
In the USA, the three nationwide credit bureaus are Equifax, Experian and TransUnion. In the UK, statutory credit reports are available from four credit reference agencies: Experian, Equifax, TransUnion and Crediva. Each uses its own scoring scale.
What Affects Your Score
Most scoring models consider similar factors:
| Factor | What it means | Relative importance |
|---|---|---|
| Payment history | Paying on time, every time | Very high |
| Credit utilisation | Balances compared with credit limits | High |
| Length of credit history | Age of your oldest and average accounts | Medium |
| Credit mix | Different types of credit, such as cards and loans | Lower |
| New credit | Recent applications and new accounts | Lower |
Payment history and utilisation usually have the biggest impact.
How to Check Your Credit Report for Free
In the USA, you can get free credit reports from each of the three bureaus through AnnualCreditReport.com, the official site authorised by federal law. Be careful with look-alike sites that charge fees. In the UK, you can check your statutory credit report from each of the four agencies for free, and inaccurate entries can be disputed.
Checking your own report does not lower your score.
Fixing Errors on Your Report
Review your report for:
- accounts you do not recognise (a possible sign of identity theft);
- late payments you believe are wrong;
- incorrect personal details;
- debts that should have been removed.
You can dispute errors directly with the credit bureau and the company that reported the information. In the USA, the Consumer Financial Protection Bureau explains the dispute process.
Practical Steps to Improve Your Score
- Pay every bill on time. Set up automatic minimum payments to avoid accidental late payments.
- Reduce your utilisation. Try to keep balances well below your credit limits; many experts suggest under 30%, and lower is better.
- Do not close old accounts unnecessarily. Older accounts lengthen your credit history.
- Limit new applications. Several hard inquiries in a short time can lower your score.
- Register to vote where relevant. In the UK, being on the electoral register helps lenders confirm your identity and address.
- Be patient. Negative items fade in impact over time as you build positive history.
Building Credit From Scratch
If you are new to credit, for example because you recently moved to a new country, options can include:
- a secured credit card backed by a deposit;
- a credit-builder loan from a bank or credit union;
- being added as an authorised user on a responsible family member’s card;
- reporting rent payments where services allow it.
Use any credit lightly and repay in full each month.
Credit Scores and Job Searches
In the USA, some employers may check credit reports for certain roles, but only with your written permission, and federal law gives you rights if the report is used against you. Many states and cities restrict this practice further. Employers see a version of your report, not your credit score.
Protecting Yourself From Identity Theft
- never share your Social Security number or bank details with unverified “employers”;
- consider a credit freeze if your data may have been exposed; in the USA, freezes are free;
- report identity theft to the relevant authority; in the USA, IdentityTheft.gov provides a recovery plan.
Myths About Credit Scores
- Myth: checking your own score hurts it. Fact: it does not.
- Myth: you must carry a balance to build credit. Fact: paying in full is best.
- Myth: your income is part of your credit score. Fact: income is not on your credit report, though lenders may consider it separately.
How Long Negative Information Stays on Your Report
Late payments, defaults and similar records do not stay on your credit file forever. In many countries, most negative information is removed after a set number of years. For example, in the UK, most records typically stay on your credit file for six years, and in the US many negative items can remain for up to seven years. The impact usually fades over time, especially if you build a good recent payment history. Check the rules in your country with the official consumer protection agency.
A Worked Example of Credit Utilisation
Suppose you have two credit cards:
| Card | Credit limit | Balance | Utilisation |
|---|---|---|---|
| Card A | 2,000 | 1,200 | 60% |
| Card B | 3,000 | 300 | 10% |
| Total | 5,000 | 1,500 | 30% |
Your overall utilisation is 30%, but Card A is at 60%. Scoring models often look at both overall and per-card utilisation. Paying Card A down to 400 would reduce your total utilisation to 14% and bring Card A to 20%, which may help your score. Paying before the statement date can also reduce the balance that is reported.
Shopping Around for Loans
When you apply for credit, the lender usually makes a hard inquiry, which can lower your score slightly for a while. Checking your own score, or “soft” checks used for pre-qualification, do not affect your score.
If you are comparing mortgage, car or student loan rates in the USA, commonly used scoring models treat several inquiries for the same type of loan within a short period as a single inquiry. The length of that period depends on the scoring model, so it is sensible to do your rate shopping within a couple of weeks. Many lenders also offer eligibility checks that use a soft search, which lets you compare likely offers without affecting your score.
Keeping Old Accounts
Closing an old credit card can reduce your total available credit and shorten your credit history. If an old card has no annual fee, keeping it open and using it occasionally can help your score, as long as you pay it off in full.
Frequently Asked Questions
What is a good credit score?
It depends on the scoring model. For common US models ranging from 300 to 850, scores in the upper ranges are generally considered good.
How long does it take to improve my score?
Some changes, like lower utilisation, can help within a few months. Recovering from serious late payments takes longer.
Will paying off a loan increase my score?
It can help overall, though closing an account can cause small short-term changes.
Does my credit history follow me to another country?
Usually not. Credit histories are generally country-specific.
Can I remove correct negative information?
Accurate information generally stays for a set period set by law, but its impact reduces over time.
Should I pay a company to fix my credit?
Be cautious. You can dispute errors yourself for free.
