You can improve your credit score by following four core principles: know what is on your report, fix anything that is wrong, pay everything on time, and keep your credit card balances low. These steps will not produce overnight results, but followed consistently they will produce a meaningful improvement within three to six months.
Short Summary
Your credit score is calculated by Experian, Equifax, and TransUnion using the data they hold on your financial history. Each agency uses its own scoring model, so your score may differ between them. Lenders check one or more of these files when assessing your application.
Errors on credit files are not uncommon. Checking all three reports and correcting any mistakes is one of the fastest ways to improve your score, because errors that make you look higher-risk can be removed entirely.
The two most heavily weighted factors in your credit score are payment history and credit utilisation. Paying on time and keeping card balances below 30 per cent of your limit will produce the largest improvement over time.

1. Check your credit report with all three agencies
Most people assume their credit report is accurate without ever checking it. Credit reference agencies hold data submitted by lenders, and mistakes do occur: closed accounts listed as open, payments recorded as missed when they were made on time, or even accounts that belong to someone else entirely.
In the UK, your credit file is held by three agencies:
- Experian: free trial via creditexpert.co.uk, then £14.99/month; or free basic report via the statutory route
- Equifax: free report and score via ClearScore (clearscore.com)
- TransUnion: free report and score via Credit Karma (creditkarma.co.uk)
Check all three, because different lenders use different agencies. An error on one file that you have never looked at could be silently costing you on every application.
2. Dispute errors on your credit report
If you find an inaccuracy, raise a dispute with the relevant agency directly through their online portal. Under the UK GDPR and the Consumer Credit Act, credit reference agencies are required to investigate your dispute and correct or remove information that cannot be verified as accurate.
Common errors worth looking for:
| Error type | What to check |
|---|---|
| Incorrect personal details | Name, address, date of birth |
| Closed accounts shown as open | Check all old accounts |
| Missed payments you did not miss | Cross-reference with your bank statements |
| Accounts you do not recognise | May indicate fraud or a linked financial associate |
| Old debts past six years | Should have dropped off automatically |
If you find accounts you do not recognise, contact the agency's fraud team as well as raising a dispute. Fraudulent accounts can be removed more quickly once fraud is confirmed.
3. Make all payments on time, every month
Payment history is the most significant factor in your credit score. Every missed or late payment is reported by the lender and stays on your file for six years. One missed payment on a credit card or loan can reduce your score by a meaningful amount immediately.
The simplest solution is direct debits. Set up a direct debit for at least the minimum payment on every credit account so that a busy month or a forgotten due date never becomes a missed payment. If you can pay the full balance each month, do so - this also avoids interest charges.
4. Reduce your credit card balances below 30 per cent of your limit
Credit utilisation is the second most important factor in your score. It measures how much of your available credit you are currently using. Most credit reference agencies and lenders regard utilisation above 30 per cent as a negative signal.
If your credit card has a £2,000 limit, keep your balance below £600. If you have multiple cards, calculate your total utilisation across all of them, not just on individual cards.
Paying down balances is one of the fastest ways to see a score improvement, sometimes within a single billing cycle. If you cannot pay down the debt immediately, spreading the balance across multiple cards to reduce utilisation on each individual card can also help.
FAQ
How long does it take for my credit score to improve?
Correcting errors and registering to vote can show an effect within weeks. Paying down balances typically improves your score within one to two months. Building a consistent record of on-time payments takes three to six months to produce a noticeable improvement. Recovering from defaults or CCJs takes years.
Can I get my credit report for free?
Yes. You can access your Equifax report and score for free through ClearScore, and your TransUnion report and score for free through Credit Karma. Experian offers a free basic statutory report, or a detailed report with score through their CreditExpert trial. Your statutory credit report from any agency costs £2 and shows the raw data without a score.
Will disputing an error always get it removed?
No. The credit reference agency must investigate your dispute and determine whether the information is accurate. If the lender confirms the information is correct, it will remain on your file. If they cannot verify it within 28 days, the agency is required to remove or amend it.
Does applying for a new credit card hurt my score?
A credit application triggers a hard search, which is recorded on your file for 12 months. A single hard search has a modest impact, but several in a short period will reduce your score more significantly. Use a soft-search eligibility checker before applying to assess your chances without affecting your score.
What is the fastest way to raise my credit score?
Fixing a verified error on your credit report is the fastest way, as it can take effect within weeks and potentially removes a significant negative mark entirely. After that, paying down your credit card balances below 30 per cent of your limit is typically the next fastest improvement.
Should I close credit cards I am not using?
Generally no. Closing a card reduces your available credit and pushes your utilisation ratio up, which can lower your score. It also shortens the average age of your credit accounts. Keep old cards open and use them for occasional small purchases unless there is a compelling reason to close them, such as a high annual fee.
