How to Improve Your Credit Score
12+ proven, actionable tips to boost your credit rating with all three UK agencies.
Improving your credit score does not happen overnight, but with the right steps it is entirely achievable. Whether you are recovering from missed payments, building credit for the first time, or simply want a higher number before applying for a mortgage or credit card, these UK-specific tips will help. Every action below is based on the criteria used by Experian, Equifax and TransUnion — the three credit reference agencies that determine your score.
Immediate Steps That Can Boost Your Score
1. Register on the Electoral Roll
This is the single quickest way to improve your credit score. Registering at your current address confirms your identity and residence, which lenders and credit agencies value highly. You can register online at GOV.UK in under five minutes. If you are not eligible to vote (for example, non-UK/Commonwealth citizens), you can send proof of address directly to the credit agencies instead.
2. Check Your Credit Report for Errors
Mistakes on your credit file are more common than you might think. Incorrect addresses, accounts that do not belong to you, or outdated information can all drag your score down. Use ClearScore, Credit Karma or MSE Credit Club to review your report with each agency for free. If you spot an error, raise a dispute directly with the relevant agency — they are legally required to investigate and correct any inaccuracies. For more detail, review our guide on how to read your credit report.
3. Close Unused Credit Accounts (Selectively)
Having too many open credit accounts can make lenders nervous, even if they have zero balances. Consider closing accounts you no longer use — but keep your oldest accounts open, as a longer credit history helps your score. The key is balance: enough accounts to show you can manage credit, but not so many that it looks risky.
4. Sever Financial Links with Ex-Partners
If you have had a joint account, joint mortgage or any financial association with someone whose credit is poor, their score could be affecting yours. Contact each credit reference agency to request a “financial disassociation” once the joint account is closed. This is free and usually processed within a few weeks.
Longer-Term Strategies That Work
5. Always Pay on Time
Payment history is the single most influential factor in your credit score. Even one missed payment can cause a significant drop and remain on your file for six years. Set up direct debits for at least the minimum payment on all credit commitments. If you are struggling to pay, contact your lender before missing a payment — many will offer a payment plan that avoids a negative mark.
6. Keep Credit Utilisation Below 30%
Credit utilisation is the percentage of your available credit that you are currently using. If you have a £5,000 credit limit and a £2,500 balance, your utilisation is 50% — which is too high. Aim to keep this below 30%, and ideally below 25%. You can reduce utilisation by paying down balances or requesting a credit limit increase (though only do the latter if you will not be tempted to spend more).
7. Use a Credit Builder Card
If you have poor or thin credit, a credit builder card is one of the best tools available. These cards typically have low credit limits and higher interest rates, but the APR does not matter if you pay the full balance each month. Use one for a small regular purchase — such as a weekly shop or fuel — and set up a direct debit to pay it in full. After 6 to 12 months of consistent use, you should see a noticeable improvement in your score.
8. Avoid Multiple Applications in a Short Period
Each time you apply for credit, the lender performs a “hard search” on your file. Multiple hard searches in a short period suggest financial difficulty and can lower your score. Space out applications by at least three months where possible. Before applying, use eligibility checkers (available on most comparison sites and lender websites) which use soft searches to estimate your chances of approval without affecting your score.
9. Keep Old Accounts Open
The length of your credit history matters. If you have a credit card you have held for ten years, closing it removes that decade of history from your file. Even if you rarely use an old card, consider keeping it open with an occasional small purchase to keep the account active. Just make sure there is no annual fee eating into your finances.
Additional Ways to Strengthen Your Score
10. Register for Rent Reporting
If you rent your home, your monthly rent payments can now be reported to credit agencies through services like Credit Ladder and Canopy. This adds a positive payment record to your file without any additional cost in most cases. Since rent is often the largest regular payment you make, having it on your credit file can make a real difference — particularly if you have a thin credit history.
11. Add a Notice of Correction
If there are legitimate reasons for negative marks on your file — such as illness, redundancy or a dispute with a provider — you can add a “Notice of Correction” (up to 200 words) to your credit report. Lenders are required to read this before making a decision. While it will not change your score directly, it gives context that could sway a manual review in your favour.
12. Diversify Your Credit Mix
Having different types of credit — such as a credit card, a mobile phone contract and a personal loan — shows lenders you can manage various commitments. This does not mean you should take on debt unnecessarily, but if you naturally need different credit products, it can work in your favour. The key is managing all of them responsibly.
13. Stay at One Address
Frequent moves can affect your score because stability is seen as a positive signal by lenders. If you do move, update your address promptly on the electoral roll and with all your credit providers. Make sure your old address is not still showing on any active accounts.
14. Pay More Than the Minimum
While making minimum payments keeps your account in good standing, paying more reduces your balance faster and lowers your credit utilisation. This is especially important for credit cards with high balances. Even an extra £20 per month above the minimum can make a meaningful difference over time, both to your score and to the total interest you pay.
How Long Each Improvement Takes
| Action | Expected Timeframe | Impact |
|---|---|---|
| Register on electoral roll | 2–4 weeks | High |
| Correct report errors | 2–8 weeks | Varies |
| Reduce credit utilisation | 1–2 months | High |
| Set up direct debits | 1–3 months | High |
| Use a credit builder card | 3–6 months | Medium–High |
| Build longer credit history | 6–12+ months | Medium |
| Wait for negatives to drop off | Up to 6 years | High |
What to Do If You Have Been Refused Credit
Being declined for credit does not automatically damage your score, but the hard search from the application will be recorded. If you have been refused, do not immediately apply elsewhere. Instead, check your credit report for errors, review your score with all three agencies, and work on the tips above for at least three months before applying again.
You have the right to ask a lender why you were declined, although they are not obliged to give specific reasons. Common causes include low income relative to the amount requested, too many recent applications, or negative marks on your file. Understanding the reason helps you focus your improvement efforts.
Improving Your Credit Score FAQs
Quick wins like registering on the electoral roll or correcting report errors can show results within a few weeks. Building a stronger credit history typically takes 3 to 6 months of consistent positive behaviour such as making payments on time and keeping credit utilisation low.
Yes, reducing outstanding debt generally improves your credit score by lowering your credit utilisation ratio. However, closing old accounts after paying them off can sometimes reduce your score by shortening your credit history. Consider keeping older accounts open with a zero or low balance.
Yes, credit builder cards are specifically designed for people with poor or limited credit history. By using one responsibly — spending a small amount each month and paying the full balance on time — you demonstrate to lenders that you can manage credit, which gradually improves your score.
Yes, although it takes longer. CCJs and defaults remain on your credit file for six years but their impact lessens over time. Focus on building positive payment history alongside waiting for negative marks to expire. If a CCJ is satisfied within one month, you can apply to have it removed from the register.
No. Checking your own score creates a soft search that only you can see. It has no impact on your credit rating. You should check regularly to monitor progress and spot any errors or fraudulent activity on your file.
