Last updated: 4 November 2026. General information, not financial advice.
Maybe you’ve been turned down for a phone contract, or you’re hoping to get a mortgage next year and your score looks lower than you’d like. Or maybe you’ve just moved to the UK and found you have no credit history at all. Whatever brought you here, the good news is that improving your credit score is mostly about small, free habits, not expensive fixes.
This guide gives you 15 practical steps, explains what actually affects your score, and is honest about how long it takes. It’s part of my debt and credit UK guide.
Before you start: check your report with every agency first, so you know what you’re working on. Here’s how to check your credit score for free. And remember: you never need to pay a “credit repair” company. MoneyHelper points out you can do all of this yourself for free.
What affects your credit score?
| Helps | Hurts |
|---|---|
| Paying every bill on time | Late or missed payments |
| Being on the electoral roll | Not being registered to vote |
| Using a small share of your credit limits | Being close to your limits |
| A long, steady credit history | Lots of applications in a short time |
| Stable address history | Defaults, CCJs, IVAs, DROs or bankruptcy |
| Accurate, up-to-date information | Errors, fraud or old financial links |
Quick wins (can show within a month or two)
1. Fix mistakes on your report
Wrong addresses, accounts you don’t recognise, late payments that weren’t late. Contact the lender that reported it and raise a dispute with the agency showing it. Do this with each agency, because they don’t share corrections.
2. Register to vote at your current address
Lenders use the electoral roll to confirm who you are and where you live. Register at gov.uk/register-to-vote. If you can’t register (for example, if you’re not eligible to vote), you can add a note to your credit file with proof of address.
3. Remove old financial links
If you once had a joint account or loan with someone, you may be “financially associated” with them. If you no longer share any credit, ask each agency to add a notice of disassociation.
4. Bring down your credit card balances
Using a lot of your available credit can make you look stretched. This is called credit utilisation. If you have a £2,000 limit and a £1,800 balance, that’s 90%. Many people aim to keep it well below half, and lower is generally better.
Tip: your balance is usually reported around your statement date. Paying down before then can make your reported balance lower.
5. Check for fraud
A hard search or account you don’t recognise could mean someone has used your details. Contact the lender and agency straight away, and report it to Report Fraud (0300 123 2040).
Steady habits (build up over months)
6. Pay everything on time, every time
Payment history matters more than anything else. Set up Direct Debits for at least the minimum on every card and loan, so you never miss one by accident.
7. Don’t apply for lots of credit at once
Every full application leaves a hard search that lenders can see. Several in a short time can make you look desperate for credit. Space out applications, ideally by a few months.
8. Use eligibility checkers first
Most lenders and comparison sites have eligibility checkers that use a soft search (invisible to lenders). They show how likely you are to be accepted before you apply.
9. Keep old accounts open (if they’re free)
An older credit history can help. If you have an old card with no annual fee that you don’t overspend on, keeping it open can support your history and your available credit. Close it if it tempts you or charges a fee.
10. Keep your address history stable
Lots of moves in a short time can make you harder to verify. If you’ve recently moved, make sure every account has your new address.
11. Use Experian Boost or similar tools
MoneyHelper mentions that Experian Boost can add some regular payments, like council tax and certain subscriptions, to your Experian score by connecting your bank account. It’s free and only affects your Experian score, not the others.
If your score is low because of past problems
12. Add a Notice of Correction
If missed payments happened for a reason, such as illness, redundancy or bereavement, you can add a short note (up to 200 words) explaining it. MoneyHelper says you need to add it with each agency, and that it won’t change your score, but lenders will see it and may take it into account.
13. Deal with defaults and arrears
If you have accounts in arrears, agreeing a payment plan stops further missed payments building up. A default stays on your file for six years from the date it was recorded, whether or not you’ve paid it, but showing it as “satisfied” (paid) looks better to lenders.
14. Pay off a CCJ quickly if you can
In England and Wales, if you pay a County Court Judgment in full within one month, you can apply to have it removed from your credit file. After that, paying it marks it as “satisfied”, and it drops off after six years.
If you’re starting from scratch
15. Build a history carefully
If you’ve never borrowed, moved to the UK recently, or are young, you may have a “thin” credit file. Some ways people start building one:
- Open a UK current account and manage it well (stay within any overdraft limit)
- Register to vote
- Put a household bill in your name, like energy, broadband or a mobile contract, and pay on time
- A low-limit credit card, used for small regular spending and paid off in full every month. MoneyHelper suggests this can help if you have little or poor credit history, as long as it’s from a regulated provider and you clear it in full.
If you use a credit card to build credit, set up a Direct Debit for the full balance. That way you build a record without paying interest. My guide to credit cards for beginners explains how to use one safely.
How long does it take to improve a credit score?
There’s no fixed timeline, but roughly:
| Action | When it might show |
|---|---|
| Fixing an error | Often within a few weeks of the dispute being resolved |
| Registering to vote | Usually within a month or two |
| Lower credit card balances | After the next statement is reported |
| Building a new history | Several months of on-time payments |
| Recovering from missed payments | The impact fades over time; the record stays for six years |
| Defaults and CCJs | Stay for six years, with less impact as they age |
Rough guide only. Every lender and agency updates on its own schedule.
If you need a mortgage or big loan soon, start at least three to six months before applying, so fixes and new balances have time to show.
What doesn’t help (or can harm)
- Paying for credit repair: you can do everything yourself for free.
- Checking your score often doesn’t harm it, but it doesn’t help either. Action does.
- Taking out credit you don’t need just to “build credit”.
- High-cost borrowing like payday loans, even if repaid, can put some lenders off.
- Closing all your cards at once after paying them off.
Improve credit score: people also ask
How can I improve my credit score fast in the UK?
The quickest wins are correcting errors on your report, registering to vote at your current address and reducing your credit card balances compared with your limits. These can show within a month or two. Long-term, paying on time every month helps most.
How long does it take to build a good credit score?
If you’re starting from nothing, several months of on-time payments on a few accounts can build a basic history, and it keeps improving over the following years. After missed payments, the impact fades over time, but the record stays for six years.
Does paying off a credit card improve my score?
Usually, yes. Lower balances compared with your limits reduce your credit utilisation, which can help. Keep paying on time and think before closing the card, as that reduces your available credit.
Does being on the electoral roll help my credit score?
Yes. Lenders use it to confirm your identity and address. Register at your current address, and update it when you move.
Can I remove a missed payment from my credit file?
Only if it’s wrong. If it’s accurate, it stays for six years, although its impact fades. If it’s a mistake, dispute it with the lender and the agency. If there was a good reason for it, you can add a Notice of Correction.
Does rent count towards my credit score?
Not always. Some rent-reporting schemes share on-time rent payments with credit reference agencies, but not every landlord uses one. Ask your landlord or letting agent whether your rent is reported.
Summary
- Quick wins: fix errors, register to vote, lower balances, remove old links.
- Long-term: pay on time, space out applications, use eligibility checkers.
- Past problems: add a Notice of Correction, agree payment plans, deal with CCJs quickly.
- Starting from scratch: build a history carefully and pay in full.
- It takes time, so start months before a big application.
