You can check your credit score in the UK for free through several online services, and doing so takes just a few minutes. The three main credit reference agencies, Experian, Equifax, and TransUnion, each calculate your score differently and use different scales, so it’s worth checking more than one to get a full picture of how lenders see you.
The Three UK Credit Reference Agencies
Every lender that runs a credit check on you pulls data from one or more of three agencies: Experian, Equifax, and TransUnion. Each agency collects its own version of your credit history and generates its own score on its own scale. Experian scores run from 0 to 1,250. Equifax uses a range of 0 to 1,000. TransUnion scores go up to 710. A “good” score at one agency looks nothing like a “good” score at another, so comparing numbers across agencies is meaningless. What matters is where your score falls within each agency’s own bands.
Here’s how each agency defines its ranges:
- Experian: Poor is 0 to 640, fair is 641 to 860, good is 861 to 1,120, and excellent is 1,121 or higher.
- Equifax: Poor is 0 to 438, fair is 439 to 530, good is 531 to 810, and excellent is 811 or higher.
- TransUnion: Poor is 0 to 550, fair is 551 to 565, good is 566 to 627, and excellent is 628 or higher.
Because lenders don’t all use the same agency, a rejection from one lender doesn’t necessarily mean your score is low everywhere. Checking all three gives you the clearest view.
Where to Check for Free
You don’t need to pay to see your credit score. Each agency offers a free route, either directly or through a partner service.
Experian lets you create a free account on its website or app to view your Experian score and a basic version of your credit report. It also offers a paid subscription with more detailed monitoring features, but the free tier is enough to see your score and the key information on your file.
Equifax data is available for free through ClearScore, a popular app and website. You sign up with ClearScore, and it pulls your Equifax report and score at no cost. ClearScore makes money by recommending financial products, not by charging you.
TransUnion data is available through Credit Karma and also through MoneySavingExpert’s Credit Club. Both are free and show your TransUnion score along with a copy of your TransUnion credit report.
Signing up for any of these typically requires your name, date of birth, current and previous addresses, and some identity verification questions based on information already in your credit file. The whole process usually takes under five minutes.
Checking Won’t Hurt Your Score
A common worry is that looking at your own score will lower it. It won’t. When you check your own report, the agency records it as a “soft search.” Soft searches are visible only to you and have no impact on your score whatsoever. Lenders can’t see them, and it doesn’t matter how many times you check. You could look at your score every day without any effect.
This is different from a “hard search,” which happens when a lender checks your file because you’ve applied for credit. Hard searches are visible to other lenders and can temporarily lower your score, especially if several appear in a short period. But checking your own report never triggers one.
What to Look For on Your Report
Your credit score is a summary number, but the report behind it is where the useful detail lives. When you pull up your report, look at the individual accounts listed: credit cards, loans, mobile phone contracts, and any mortgage. Each entry should show the correct balance, credit limit, and payment history. Make sure every account belongs to you and that no payments are marked as late when you paid on time.
Also check your personal details. An old address that wasn’t updated, or a name spelled wrong, can cause problems when lenders try to verify your identity. If you’re not on the electoral register at your current address, that alone can drag your score down, and registering is one of the quickest ways to improve it.
Look at the “searches” section too. You should recognise every hard search listed. An unfamiliar search could mean someone applied for credit in your name, which is an early sign of fraud worth investigating immediately.
How to Fix Errors on Your Report
If something on your report looks wrong, contact the credit reference agency directly. The agency will reach out to the company that supplied the information and ask them to verify it. While the dispute is being investigated, the agency will usually add a note to your report flagging the entry as disputed.
If the company confirms the information is correct but you still feel it needs context, you can add what’s called a Notice of Correction. This is a short written statement attached to a specific entry on your report. For example, if you missed payments because you lost your job or went through a serious illness, a Notice of Correction lets you explain that to future lenders. Any lender who checks your file is required to see your statement and should take it into account. There’s no guarantee it will change a lending decision, but it gives you a way to provide your side of the story.
Keep your statement clear and factual, and avoid naming specific organisations. If you want the notice to appear across all three agencies, you’ll need to contact each one separately, since they maintain independent records. If you and the agency can’t agree on the wording, the Information Commissioner’s Office can step in to review it.
How Often to Check
Checking once a month is a reasonable habit for most people. Your report updates as lenders send new data to the agencies, which typically happens on a monthly cycle. If you’re planning to apply for a mortgage, a car loan, or any significant credit in the near future, start checking a few months ahead. That gives you time to spot and resolve any errors, pay down balances, and make sure your electoral roll registration is current before a lender pulls your file.
Most of the free services offer email or app notifications when something on your report changes, such as a new account appearing or a significant score movement. Turning these on means you don’t have to remember to log in manually, and you’ll catch any unexpected activity quickly.
