To improve your credit score in the UK, start by checking your reports at all three credit reference agencies (Experian, Equifax and TransUnion) for free, then fix the basics: get on the electoral roll, pay every bill on time, keep your credit card balances well below their limits, and correct any mistakes. Most people see a difference within one to three months, and none of it needs a paid service.
How UK credit scores actually work
There is no single UK credit score. Three credit reference agencies (CRAs) each hold a file on you:
| Agency | Score range (checked November 2026) | Free way to see it |
|---|---|---|
| Experian | 0–1,250 (moved from 0–999) | Free Experian account |
| Equifax | 0–1,000 | ClearScore, or Equifax’s own free service |
| TransUnion | Scale being overhauled in 2026 | Credit Karma, or TransUnion’s statutory report |
The scores are just a guide. When you apply for a credit card, loan, mortgage or even a phone contract, the lender looks at your report (your accounts, payment history, searches and address links) and runs it through its own scoring. A “fair” score with one agency might still get you accepted, while an “excellent” score will not help if your income does not support the borrowing.
That is why the most useful thing you can do is check all three reports, because lenders do not all use the same one, and an error might only appear on one of them.
Where to check for free
- ClearScore shows your Equifax score and report free, updates it regularly, and has an eligibility checker that shows which cards and loans you are likely to be accepted for without a hard search.
- Experian gives you a free Experian score and account. It also offers a paid subscription with a full report and alerts, which you do not need to improve your score; you can cancel any trial before it charges.
- TransUnion data is free through Credit Karma.
- You also have a legal right to your statutory credit report from each agency free of charge.
Checking your own file is always a soft search and never affects your score.
The 8 things that improve your score
1. Register on the electoral roll
Lenders use the electoral register to confirm who you are and where you live. Not being on it is one of the most common reasons people get declined, especially after moving house.
- Register at gov.uk/register-to-vote. It takes about five minutes.
- You need to be eligible to vote in some UK election. Most British, Irish and qualifying Commonwealth citizens are, and EU citizens can register in many cases; check the eligibility rules on the site.
- It can take a few weeks to be added, and then up to a month or so to show on your credit reports.
If you are not eligible (for example, some visa holders), add a note to your file explaining why and give lenders proof of address. Having a UK current account and bills in your name helps.
2. Pay everything on time, every time
Payment history is the biggest factor. Set up direct debits for at least the minimum payment on every credit card, loan and contract, then pay extra manually if you can. One missed payment can stay on your file for six years.
If you have already missed payments, the best fix is a long run of on-time payments afterwards. Their weight drops with time.
3. Lower your credit utilisation
Credit utilisation is how much of your available credit you are using. If you have a £2,000 limit and owe £1,800, you are using 90%, which looks like you depend on credit.
- Aim for under 30%, and under 10–20% is better.
- Pay before the statement date, not just the due date. Card companies usually report the statement balance to the agencies, so paying it down first makes your utilisation look lower.
- Do not close old cards just because they are paid off. An unused card with a £3,000 limit keeps your overall utilisation down and adds to your history. Keep it active with a small purchase every few months, paid off in full.
If you are carrying high balances, our guide on how to pay off debt shows how to clear them in the right order, which helps your score at the same time.
4. Check for errors and fix them
Look for accounts you do not recognise, wrong addresses, payments marked late that were on time, and accounts still showing a balance after you paid them off. You can raise a dispute with the agency (free), which will check with the lender. If you think you have been a victim of identity fraud, contact the lender and report it to Action Fraud.
You can also add a notice of correction of up to 200 words to explain a genuine problem, such as missed payments during a serious illness.
5. Remove old financial links
If you have ever had a joint account or joint loan with someone, your files are linked and their credit behaviour can affect your applications. If you are no longer financially connected (for example, after a break-up), ask each agency for a notice of disassociation. It is free.
6. Space out credit applications
Every application for credit leaves a hard search on your file. Several in a short period can look like you are desperate for credit. Use soft-search eligibility checkers before applying, and leave a few months between applications where you can.
7. Avoid red flags
Payday loans, frequent use of an overdraft at its limit, and cash withdrawals on a credit card can all count against you with some lenders, even if your score does not drop. Buy now pay later plans are increasingly reported to credit agencies too, so treat them like any other credit.
8. Stay at the same address and bank
Stability helps. Lenders like to see you have been at the same address and had the same current account for a while. This is not a reason to avoid moving, but it is a reason to update your address everywhere promptly when you do.
Building credit from scratch
If you are new to the UK, young, or have avoided credit entirely, you may have a “thin file”. Lenders are not sure about you because there is nothing to judge. Options that help, from lowest to highest risk:
| Option | How it works | Watch out for |
|---|---|---|
| Electoral roll and a UK current account | The foundation; proves who and where you are | Takes a month or two to show |
| Bank data sharing tools | Some services (such as Experian Boost) let you share your current account data so on-time bills and subscriptions count | Only some lenders use this data |
| Rent reporting | Services that report your on-time rent to the agencies | Some charge a monthly fee |
| Credit builder savings products | You save a fixed amount monthly and your payments are reported as if they were a loan | Often have a monthly fee; check total cost |
| Credit builder credit card | A card with a low limit (often a few hundred pounds) aimed at people building credit | Very high APR, so you must pay in full every month |
The safest pattern with a credit builder card: put one regular bill on it (for example your phone bill), set a direct debit to pay the full balance every month, and leave it alone. After six to twelve months your file will look very different.
If you are new to the UK and need a bank account first, our guide to the best banking apps in the UK covers which ones are easiest to open.
What does not help (or matters less than you think)
- Paying for a credit score service. The free versions give you everything you need to improve your score.
- Earning more. Your salary is not on your credit report, though lenders ask about it for affordability.
- Closing all your cards. This can lower your score by reducing available credit and shortening your history.
- Credit repair companies. No one can legally remove accurate negative information from your file. Anyone promising to do so for a fee is wasting your money. You can dispute genuine errors yourself, free.
When your credit problem is really a debt problem
If your score is low because you are behind on payments and cannot catch up, focusing on the score is the wrong way round. Speak to a free debt adviser first. Our guide to free debt help in the UK explains where to go. Once the debt is under control, your score will recover over time.
Our pick: Sign up for both ClearScore (Equifax data) and a free Experian account so you can see two of the three main reports without paying. Then check you are on the electoral roll, and use ClearScore’s eligibility checker before you apply for anything.
Frequently asked questions
How can I improve my credit score quickly in the UK?
The quickest wins are registering on the electoral roll at your current address, paying down credit card balances so you use well under 30% of your limits, fixing any errors on your reports, and removing old financial links to ex-partners. Changes usually show within one to two months, once lenders and the electoral register update.
What is a good credit score in the UK?
It depends on the agency, because each uses its own scale. Experian runs from 0 to 1,250 and Equifax from 0 to 1,000, and TransUnion has been changing its scale (checked November 2026). Lenders never see 'your score' anyway; they look at your report and apply their own scoring.
Does checking my own credit score lower it?
No. Checking your own report is a soft search, which only you can see. Only hard searches, made when you actually apply for credit, are visible to lenders and can affect your chances.
How long does it take to build credit from nothing?
Most people who start from no history can build a usable credit file in six to twelve months by joining the electoral roll, getting a credit builder card or similar product, and paying it off in full every month.
How long do missed payments and defaults stay on my file?
Late payments, defaults, CCJs and insolvencies stay on your credit file for six years. Their impact fades over time, especially once you show a steady record of on-time payments.
Does paying rent improve my credit score?
Not automatically. Rent only counts if it is reported to the credit reference agencies, which some councils, housing associations and letting agents do. You can also opt in through rent reporting services so your on-time payments appear on your file.
