In this simple explainer, we break down why your credit score might not be as high as you'd like it to be and share 10 easy ways to help you improve your credit score in the UK. Whether you want to increase credit score quickly or boost credit score gradually, these methods work.

Your credit score plays a crucial role in determining whether you qualify for loans, credit cards, or mortgages - and at what interest rate. A low score can cost you thousands in added interest over time, but the good news is that learning how to improve credit score doesn't have to be hard. This guide offers 10 steps that may help improve your credit score, save money, and open up better financial opportunities. Here's everything you need to know.

What is a credit score?

What is a credit score in the UK? A credit score in the UK is a number that represents your creditworthiness to lenders. Experian scores range from 0-1250 (updated in late 2025), while Equifax and TransUnion use different scales (typically 0-999 or 0-710). Here's what you need to know:

• Calculated by: Experian, Equifax, and TransUnion

• Based on: Payment history, credit utilisation, and account age

• Used for: Loan approvals, interest rates, and credit limits

Credit reference agencies use your credit history to work out your credit score. The UK has three credit reference agencies (Experian, Equifax and TransUnion) that score you.

They build your credit reports using information about you, your UK bank accounts and payment history. Each uses roughly the same formula, meaning they are all looking for the same signals that you are worthy of credit.

What does your credit score start at in the UK?

What credit score do you start with?

It's a common misconception that your credit score starts at zero - this isn't true. Your credit score doesn't start at zero. It starts developing when you begin using credit. If you've never used credit, you may be considered 'credit invisible.' Scores typically begin somewhere in the middle range and improve with responsible credit usage.

How to improve credit score quickly: 10 strategies that may help increase your score

How to improve credit score in 10 steps: Here are a few things you can immediately do to help improve your credit score and, in turn, prove your reliability to these agencies:

Step 1: Use a credit card often and for small amounts

You may be able to help improve your credit scores by using a credit card regularly and responsibly. Spending small amounts and paying off your bill each month shows lenders they can trust you to repay what you borrow.

Step 2: Only use between 10% and 30% of your credit limit, which may help improve your credit score

Avoid using too much of your available credit for a better credit score. By only using a percentage of your credit limit-preferably 30%-you show lenders that you can manage your credit sensibly. This strategy may help boost your credit scores while showing responsible credit management. This credit utilisation ratio is crucial for improving your credit scores.

Step 3: Fix mistakes in your report

Your credit score is based on the information in your credit report. If this information isn't accurate (e.g. an account appears as 'open' when it is 'closed'), your credit score won't be either. This could mean your score is lower than it should be. By checking your credit report regularly, you can spot and fix any mistakes, which may help improve your credit scores more quickly.

ClearScore gets your credit report from Equifax, the credit reference agency. So, if you find any mistakes on your credit report, you'll need to talk to Equifax directly. Read more about this in our credit reports & scores FAQs.

Step 4: Register for the electoral roll to boost credit score

Getting on the UK electoral roll or electoral register lets credit reference agencies check your identity, making you look more reliable to lenders. Banks use the registry to verify who you are, including your name and other basic information. Not being registered can negatively impact your scores and the likelihood of successful credit applications.

Register for the electoral roll or, if you're not sure if you're registered, you can check with your local authority.

Step 5: Avoid making multiple credit applications in a short space of time

Every time you make a credit application, a hard search is carried out on your account, which affects your credit scores. If you make too many credit applications in a short period of time, lenders may think you're desperate for credit.

So, if you're rejected for credit, try waiting a while before you apply again. While you wait, check your credit report to ensure everything is right.

Step 6: Use an eligibility checker

Avoid getting rejected for credit by using an eligibility check or a soft search before you apply. This means lenders can see some information about your credit history, but the check won't affect your credit score. Only you can see if a soft search has been carried out on your account.

We'll tell you on your 'Offers' page if you're pre-approved for a credit card or loan. Pre-approval doesn't always guarantee acceptance and is subject to lenders' checks of your credit status. ClearScore is a credit broker, not a lender.

Step 7: Get your name on some bills if it isn't already

Utility bills - such as your mobile phone contract or gas bill - count as a form of credit. If you pay them on time, they're a great way to show lenders you can pay your bills back reliably.

You may pay your share of the bills every month, but if a flatmate is directly paying the bills, your contribution will not be reflected in a credit check.

If you don't have an account, you might consider putting one or two utility bills in your name.

Step 8: Pay your bills on time, which may help increase your credit score

You may be able to boost your credit scores by paying your bills on time. Stay on top of your bills by setting up Direct Debits. This shows lenders that you can stay on top of your credit, and this may help increase your credit scores.

The more bills you regularly pay in full in your name, the better. Credit agencies will see this when they run their report.

Step 9: Look out for fraud

Identity fraud affects millions of people every year. If you fall victim, your credit scores could be damaged by becoming responsible for someone else's credit actions.

Checking your credit report regularly will help you spot financial fraud quickly. If anyone's trying to open credit in your name, you'll be able to see the early signs in the searches section of your report. This section lists all the 'hard' credit searches in your name. If there are any hard searches you don't recognise, it could be fraud (though it's always worth double-checking with the named lender). Find out more on how to check your credit report accurately.

If you suspect fraudulent behaviour on your account, you should report any activity to Action Fraud.

ClearScore Protect helps to protect you from identity fraud by scanning the dark web for passwords associated with your email address - it's free, forever. Learn more about how Protect helps keep your online identity safe.

Step 10: Make sure you have a good overall view of your finances

Your credit scores are calculated by credit reference agencies (CRA). There are three CRAs in the UK - Experian, Equifax and TransUnion (formerly Callcredit).

Each CRA may hold slightly different information about you, which means that you'll have three different credit scores. It's worth checking in with all three companies to get a good overall view of your finances and may help improve your credit scores across all agencies.

Why improve your credit score in the UK?

How long does it take to help improve your credit score?

Most credit score improvements may happen gradually over time as you build better financial habits. Some changes, like fixing errors on your credit report, can show results within a few weeks, while others may take several months of consistent behaviour.

How to increase credit score with no credit history

When you move to the UK, your credit scores abroad don't follow you. You'll start from scratch; if you play it smart, there's nowhere to go but up.

Similarly, if you're just breaking into the adult world of finance and have never had your name associated with an account, or you're simply trying to rebuild from a bad credit position, get ready to make a good impression.

Here are some ways to how to increase credit score quickly in the UK:

• Secure a credit card and establish yourself.

• Use it responsibly. Make purchases with it but don't go over your credit limit.

• Pay it off on time and in full.

• Don't spend to your limit.

If you have no credit history or poor credit history, your first card may have a low credit limit and higher interest rates. Some lenders specialise in offering credit cards for bad credit. You can read our guide to choosing the right credit card for bad credit.

If you follow these steps, your credit score will not only exist, but it may begin to rise before you know it. As your score may improve, options for better credit cards and financial perks (like mortgages and rental options) may open up, too.
