What is a good or bad credit score?

Let's break down what makes a credit score good or developing, and how your score might affect the credit offers you get.

Key takeaways

• Credit scores in the UK range from 0 up to 710, 1,000 or 1,250, depending on the credit reference agency and scoring model used.
• A good credit score typically starts at 861 on Experian's 0–1,250 scale, 531 with Equifax, and 604 with TransUnion.
• Lower credit scores can limit your borrowing options, but you can improve your score over time with consistent financial habits.
• Factors like payment history, credit utilisation, and length of credit history significantly impact your score.
• Regular monitoring helps you track progress and spot potential issues early.

When it comes to applying for credit, there's a vital piece of information that impacts how lenders and banks view you: your credit score.

Lenders use this score to decide whether to approve your applications for credit cards, loans, or mortgages, what interest rates to offer you, and what credit limits you’re eligible for.

In the UK, credit scores typically range from 0 up to 710, 1,000 or 1,250, depending on which credit reference agency calculates them. A higher score suggests you're a lower risk to lenders, whilst a lower score may indicate you've had difficulties managing credit in the past.

What is a credit score?

A credit score is a three-digit number that summarises your creditworthiness at a specific point in time. It's calculated using information from your credit report, which contains details about your borrowing history, including credit cards, loans, mortgages, and payment patterns. Lenders use credit scores as a quick way to assess risk when you apply for credit. A higher score suggests you're more likely to make payments on time and manage credit responsibly, whilst a lower score may indicate higher risk.

How credit scores are calculated

Several key factors influence your credit score:

Payment history plays the biggest role in determining your score. Making payments on time consistently helps build a strong credit profile, whilst missed or late payments can significantly damage your score.

Credit utilisation measures how much of your available credit you're using. Keeping your credit card balances well below your limits, ideally under 30%, demonstrates responsible credit management.

Length of credit history considers how long you've been using credit. A longer history of responsible credit use generally helps your score, as it provides more data about your borrowing behaviour.

Types of credit in your name can also impact your score. Having a mix of different credit types, such as credit cards and loans, may be viewed positively if managed well.

Recent credit applications can temporarily affect your score. Multiple applications in a short period might suggest financial difficulty, though the impact usually lessens over time.

Credit score bands explained

There is no ‘magic’ credit score that will guarantee that you get accepted for credit. Also, different lenders are looking for different things, so you might get refused credit by one lender and accepted by another.

Remember, your credit score is a useful indication of your creditworthiness, but lenders will look at other factors (such as your income and debt levels) before deciding whether to lend to you.

Here's how we show you your Equifax score at ClearScore:

At ClearScore, we believe every credit score tells a unique story. We don't label lower scores as "bad" because everyone's financial journey is different. Whether you're just starting to build credit or working to improve it, your score is simply where you are right now, not where you'll always be.

There are a number of things that affect your credit score, including:

Your credit score is calculated by a credit reference agency (CRA). There are three CRAs in the UK: Equifax, Experian and TransUnion. At ClearScore, we show you your Equifax credit score, which ranges from 0 to 1000. Each CRA is sent information by lenders about the credit you have and how you manage it. Other information, such as public records like the electoral roll and court judgments, are also sent to the CRAs and form part of your credit report.

Differences in credit scoring models

These agencies may have slightly different information about you, as not all lenders report to all three agencies. This means your credit score can vary between agencies, even though they're measuring the same thing. Each credit reference agency uses its own scoring model and scale. Experian has updated its credit score range to 0–1,250, with scores of 1,121–1,250 considered excellent, whilst Equifax and TransUnion continue to use their established ranges. These differences mean you might see varying scores when checking with different services, but this doesn't necessarily indicate errors in your credit file.

Here are the credit score bands used by the three main UK credit reference agencies (CRAs)

These bands are for general guidance only and may be updated periodically by each CRA, so checking directly with Experian, Equifax and TransUnion is recommended.

As a guide, a good credit score in the UK is often taken to be 861 or above with Experian, 531 or above with Equifax, and 604 or above with TransUnion. Scores in this range suggest to lenders that you're likely to manage credit responsibly.

Having a good credit score may increase your chances of being approved for credit applications and you may be offered better interest rates and terms, though approval and terms depend on individual circumstances and lender criteria. You might also have access to premium credit cards and higher credit limits.

What is a lower or developing credit score?

A lower credit score typically falls within the "poor" or "low" bands—below 641 with Experian, 439 with Equifax, or 551 with TransUnion on the scales shown above. Scores in this range may indicate you've had difficulties managing credit in the past, such as missed payments, defaults, or county court judgements.

The important thing to remember is that a lower score doesn't define you. Your credit score is a snapshot of your financial history, not a judgment of your character or future potential. Many people successfully improve their scores over time with consistent, positive financial habits.

Lower credit scores can make it more challenging to get approved for mainstream credit products. When approval is possible, you may face higher interest rates or need to provide additional security. However, specialist lenders exist to help people at every stage of their credit journey.

The highest and lowest credit scores in the UK

The maximum possible credit scores currently vary by agency: Experian's scale reaches 1,250, Equifax goes up to 1,000, and TransUnion's maximum is 710. These represent the best possible credit profiles.

The lowest scores start at 0 for all three agencies, representing individuals with significant credit difficulties or no credit history at all.

Why is my credit score lower than expected?

Several factors could contribute to a lower credit score:

• Missed or late payments are the most common cause of score drops.
• High credit utilisation suggests you're heavily reliant on credit.
• Recent defaults or county court judgements significantly impact scores.
• Limited credit history means there's less information for agencies to assess.
• Frequent credit applications might suggest financial difficulties.
• Errors on your credit file can incorrectly lower your score.

How credit scores affect loan and mortgage applications

Your credit score significantly influences your borrowing options. Lenders use scores to determine several key factors.

Approval likelihood: Higher scores generally lead to more approvals, whilst lower scores may result in rejections or referrals to specialist lenders.

Interest rates: Better scores often qualify for lower rates, potentially saving thousands over the life of a loan or mortgage.

Credit limits: Higher scores may qualify for larger credit limits on cards and loans.

Product availability: Premium products with better terms are typically reserved for those with excellent scores.

An excellent credit score may improve your chances of accessing competitive financial products, subject to individual circumstances and lender criteria:

• Access to 0% interest credit cards and balance transfer deals.
• Access to competitive mortgage rates, which may result in savings compared to higher rate products, subject to individual circumstances and lender criteria.
• Premium credit cards with rewards and benefits.
• Higher credit limits and more flexible terms.
• Faster approval processes for credit applications.

Tips to improve your credit score You can take several steps to improve your credit score over time.

Pay bills on time: Set up direct debits to ensure you never miss payments on credit cards, loans, or other financial commitments.

Keep credit utilisation low: Try to use less than 30% of your available credit limits across all your cards and accounts.

Check your credit report regularly: Look for errors or fraudulent activity that could be dragging down your score. You can track your score for free, for life, helping you stay on top of your credit health and spot issues early.

Don't close old accounts: Keeping older accounts open can help maintain a longer credit history, which benefits your score.

Limit new credit applications: Only apply for credit when necessary, as multiple applications can temporarily lower your score.

Common credit score mistakes to avoid

Certain behaviours can harm your credit score:

• Making only minimum payments whilst carrying high balances.
• Closing credit accounts immediately after paying them off.
• Applying for multiple forms of credit in short succession.
• Ignoring your credit report and missing errors.
• Using credit cards for cash advances regularly.
• Going over credit limits, even occasionally.

What's the difference between credit scores from different agencies? Each credit reference agency (Experian, Equifax, TransUnion) uses its own scoring models and ranges, so there is no single "universal" UK credit score. Your number can look different at each agency, even though they are all describing the same underlying credit history. Your scores may vary between them because not all lenders report to all agencies, and each uses slightly different calculation methods.

How often should I check my credit score? Checking monthly is ideal for tracking progress and spotting issues early. Free services let you monitor without affecting your score, unlike when lenders check your credit for applications.

Can I improve my credit score quickly? Credit score improvements typically take time. While some changes like correcting errors, can have immediate effects, building a consistently good payment history requires several months of responsible credit management.

Do joint finances affect my credit score? Joint accounts, mortgages, or being financially associated with someone can affect your score. Their credit behaviour may influence your creditworthiness in lenders' eyes.

What happens if I have no credit history? Having no credit history can make it difficult to get approved for credit, as lenders have no information about your borrowing behaviour. Building credit gradually through products designed for beginners can help.

Why might my credit score drop unexpectedly? Sudden drops could indicate missed payments, increased credit utilisation, new accounts, or errors on your report. Regular monitoring helps identify the cause quickly.

How does ClearScore help with credit monitoring? ClearScore gives you free access to your Equifax-based credit score and report, updated roughly once a month. The service includes personalised insights about factors affecting your score and suggestions for improvement, helping you track progress towards better credit health.
