How to Check and Improve Your Credit Score (US and UK)

Your credit score quietly shapes the rates you get on cards, loans, car finance and even some rental applications. The good news is that checking it is free, fixing errors is your right and improving it mostly comes down to a handful of steady habits. This guide walks you through how to check your credit in the US and the UK, what to look for in your report and how to nudge your score in the right direction before the new year.

Key takeaways

In the US, you can get free credit reports from Equifax, Experian and TransUnion every week at AnnualCreditReport.com, the only official site for free reports.
In the UK, there is no single score. Each agency uses its own scale, and you can get your statutory credit report free.
Lenders look at your credit report and their own data, so a clean, accurate report matters more than any one number.
Payment history, amounts owed, length of history, new credit and credit mix drive US scores. Paying on time and keeping balances low help in both countries.

Many people only look at their credit when they are about to apply for something important, like a mortgage, a car loan or a business credit card. That is the worst moment to discover a mistake, because fixing it takes time. Checking a few months ahead gives you room to correct errors and build better habits before a lender ever sees your file.

Late November is a smart time to do this. You can spot any problems before holiday spending starts, and you head into the new year knowing exactly where you stand. Let's start with what a credit score actually is, then move on to checking, fixing and improving.

Credit reports vs credit scores

These two terms get used interchangeably, but they are different things.

Your credit report is the detailed record: your accounts, balances, payment history, searches by lenders and certain public records. Credit reference agencies (called credit bureaus in the US) build it from information lenders send them.
Your credit score is a number calculated from that report. It is a quick summary of how risky you might look to a lender.

Because the score comes from the report, the report is where the real work happens. If the report is wrong, the score will be wrong too.

How US scores work

You actually have many scores, not one. Different scoring models and the three bureaus can produce slightly different numbers, and that is normal. Focus on the direction your scores are moving rather than a single exact figure.

How UK scores work

In the UK, there is no single credit score. Each agency uses its own scale:

Experian: 0 to 999
Equifax: 0 to 1,000
TransUnion: 0 to 710, moving to a new 0 to 999 scale

TransUnion is rolling out its new scale in phases from late September 2026 to June 2027, so for a while you may see two TransUnion scores. Do not panic if the number suddenly looks very different. It is a change of scale, not a change in your credit.

Most importantly, UK lenders do not see the score you see. They look at your credit report alongside their own data and decide using their own rules. So treat the score as a rough guide and the report as the thing to keep clean.

How to check your credit in the US

Getting your reports is free and takes about ten minutes.

Go to AnnualCreditReport.com. It is the only official site for free credit reports. Type the address yourself rather than clicking ads or links in emails.
Request all three reports. You can get reports from Equifax, Experian and TransUnion. Free weekly access is available, and the FTC says that weekly access is permanent.
Save a copy. Download or print each report and store it somewhere secure, so you can compare it with your next check.
Read them side by side. Not every lender reports to all three bureaus, so an account may appear on one and not the others.

Your free reports may not include a score. Many banks and card issuers show you a score in their app at no cost, which is handy for watching trends. Checking your own reports or scores does not lower them.

How to check your credit in the UK

You have a legal right to see what the agencies hold about you.

Request your statutory credit report. You can get it free from each agency: Experian, Equifax and TransUnion.
Check all three. Lenders may use one, two or all of them, and the details can differ.
Confirm you are on the electoral roll. Being registered at your current address helps lenders confirm who you are, and it is one of the simplest ways to strengthen your file.
Note your scores, but do not chase them. Remember that each scale is different and lenders do not see these numbers.

Pro tip

Set a recurring calendar reminder to check your reports, for example once a quarter. A regular, boring check catches problems early, including signs that someone has opened an account in your name.

What to look for in your report

A credit report can look dense, but you only need to check a few things carefully.

Personal details: your name, current and past addresses and date of birth. Old or wrong addresses can cause mix-ups.
Accounts you do not recognize: these can be simple errors or a sign of identity fraud.
Payment history: late or missed payments that you know you paid on time.
Balances and limits: limits that look too low or balances that are out of date.
Closed accounts shown as open, or debts you paid off still showing a balance.
Searches and inquiries: credit applications you did not make.
Financial links: in the UK, check that you are not linked to someone you no longer share finances with.

How to fix errors

If something is wrong, you do not need to pay anyone to fix it. In the US, you dispute errors directly with the bureau that shows the mistake. In the UK, contact the agency showing the error, and it can raise the issue with the lender. It also helps to contact the lender that supplied the information.

Gather proof. Bank statements, payment confirmations, letters or account closure emails.
Raise the dispute. Use the bureau or agency's online dispute process, and explain clearly what is wrong and what it should say instead.
Keep records. Note the date, the reference number and what you sent in your log.
Follow up. Check the result, then pull the report again to confirm the correction.
Check the other bureaus. The same mistake often appears in more than one place, so dispute it everywhere it shows up.

Common mistake

Paying a company that promises to "erase" bad credit. Accurate, negative information cannot simply be removed, and you can dispute genuine errors yourself for free. Be wary of anyone asking for upfront fees to repair your credit.

What moves your score, and how to improve it

US scores are built mainly from five factors. The same habits help in the UK too, because UK lenders look at similar information in your report.

Payment history

Paying on time is the foundation. Set up automatic minimum payments on every card and loan, then pay more manually when you can. If you have missed payments, the best fix is a long run of on-time ones from now on.

Amounts owed and credit utilization

Utilization is how much of your available credit you are using. Lower balances relative to your limits generally look better. Paying down card balances, or paying before the statement date so a lower balance is reported, can help. If you have several debts, a focused payoff plan like the snowball or avalanche makes this easier.

Length of credit history

Older accounts show a longer track record. Think carefully before closing your oldest card, especially if it has no annual fee. Keeping it open and using it lightly can help your history.

New credit

Applying for lots of credit in a short time can be a warning sign to lenders. Space out applications, and use eligibility checkers that use soft searches where they are available.

Credit mix

Having different types of credit, such as a card and an installment loan, can help a little. It is the least important factor, so never borrow just to improve your mix.

Hypothetical example

Imagine Amira, a self-employed bookkeeper in Manchester who plans to apply for a car loan in spring. In late November she requests her statutory reports from all three agencies. She finds she is not on the electoral roll at her new flat, and one old phone contract still shows as open. She registers to vote, disputes the phone account and sets up automatic payments on her credit card. By March her file is accurate and up to date, and she applies with confidence instead of guessing.

A simple 90-day credit routine

You will not transform your credit overnight, but three months of steady habits can make your file cleaner and stronger.

Week 1: pull all your reports, fill in the log and dispute any errors.
Week 2: set up automatic payments on every account, and in the UK, check your electoral roll registration.
Month 1: make a plan to pay down card balances, starting with whatever fits your payoff method.
Month 2: avoid new credit applications unless you really need them, and follow up on open disputes.
Month 3: pull your reports again, confirm the fixes and note any changes in your scores.

For business owners, keep in mind that business credit is a separate topic with its own reports. Your personal file still matters, because many lenders look at owners' personal credit for small businesses and new companies.

A quick note: this article is general information about credit, not personal financial or legal advice. If you are dealing with debt problems or identity fraud, speak with a qualified professional or a free service. In the US, nonprofit credit counseling from members of the National Foundation for Credit Counseling is a good start. In the UK, StepChange, National Debtline, Citizens Advice and MoneyHelper offer free help.

Frequently asked questions

Does checking my own credit lower my score?

No. Checking your own reports or scores does not hurt them. Only applications for credit, where a lender runs a hard search, can affect your score.

Why are my scores different on different sites?

Each bureau or agency may hold slightly different information, and different scoring models weigh it differently. In the UK, each agency also uses its own scale. Small differences are normal; look at the overall trend.

Why do I see two TransUnion scores in the UK?

TransUnion is moving from its 0 to 710 scale to a new 0 to 999 scale in phases between late September 2026 and June 2027. During the switch you may briefly see both. Your credit itself has not changed.

How long does it take to improve a credit score?

Fixing a reporting error can show up once the correction is made. Building a stronger history through on-time payments and lower balances takes longer, usually several months or more. Consistency matters more than speed.

The bottom line

Checking your credit is free in both the US and the UK, and it is the first step to improving it. Pull your reports, fix any errors directly with the bureau or agency, and then focus on the habits that matter most: paying on time, keeping balances low and applying for new credit only when you need it.

Take ten minutes this week to request your reports, before the holiday rush. Whatever you find, you will start the new year with a clear picture and a plan to make it better.
