What Is a Bad Credit Score? UK Ranges & How to Fix It
What is a bad credit score, and how do you know if yours falls into that category? If you've been turned down for a loan or credit card, your credit score could be the reason. In the UK, three credit reference agencies: Experian, Equifax and TransUnion, each use their own scoring system, so a bad credit score looks different depending on where you check. But here's the good news. A low credit score is not permanent.
This guide breaks down the exact ranges, explains what causes bad credit and shows you potential ways to improve your credit score.
What is a Bad Credit Score in the UK?
A bad credit score is a number that tells lenders you may be a higher potential risk when it comes to borrowing. Each credit reference agency in the UK uses a different scoring system, so there is no single number that defines bad credit across the board.
If your credit score falls into the "poor" or "very poor" band with any agency, lenders are more likely to reject your credit applications or offer you less favourable terms. Your credit history, payment history and overall financial activity all feed into how your score is calculated.
The lower your score sits, the fewer borrowing options you will typically have. A low credit score simply means there are areas of your financial history that need attention.
Bad Credit Score Ranges Across Experian, Equifax and TransUnion
Each credit reference agency varies in how it defines a bad credit score, so checking all three gives you the clearest picture. Below are the credit score ranges at the main credit reference agencies in the UK:
Experian: Credit score range from 0-1250. A poor credit score falls below 720.
Equifax: Credit score range from 0-1,000. A poor score is anything below 438.
TransUnion: Credit score range from 0-710. Scores under 565 are generally classed as poor.
If your Experian credit report or any other agency report shows a low credit score, you may find it harder to access good credit deals. But a bad credit rating does not mean the door is shut forever. Understanding where your credit score sits on these credit score ranges is the first step toward fixing it. The scoring system at each of these credit bureaus is designed to give you a snapshot, not a life sentence.

What Causes a Bad Credit Score?
1. Missed Payments and Late Repayments
Your payment history is one of the biggest factors behind a bad credit score. Every time you miss a payment or make a late repayment on a loan or credit card, it gets recorded on your credit file. Even late or missed payments on household bills and mobile phone contracts can leave a mark.
Lenders want to see that you are reliable when it comes to making payments on time. If your credit record shows a pattern of missed payments, it signals that you may struggle with credit repayments going forward. These marks can stay on your credit report for up to six years, so even past account history mistakes can still drag down your current credit score.

2. High Credit Utilisation and Debit Balances
Using too much of your available credit is another common cause of a low credit score. If you regularly max out your credit limit or carry high debit balances on credit cards and overdrafts, lenders may see you as overly reliant on borrowing.
A good rule of thumb is to stay below 30% of your agreed credit limits. If you consistently push against your credit limit, it can negatively impact your credit score and make it harder to access new credit.
3. County Court Judgements, IVAs and Defaults
Serious financial difficulties can have a lasting effect on your credit score. If you fail to repay a debt, your lender may register a default on your credit file. If the matter goes further, you could end up with county court judgements (CCJs) or individual voluntary agreements (IVAs) on your credit record.
These are among the most damaging entries a credit report can hold. Court records defaults, CCJs and IVAs remain visible for up to six years, even after the debt has been cleared. During that time, most lenders will view you as high risk, and your borrowing options will be severely limited.
Past financial difficulties do not have to define your future credit eligibility, but they do take time to clear from your credit file.
4. Too Many Credit Applications in a Short Time
Every time you apply for credit, the lender carries out a credit check. Many times, this may leave a "hard search" on your credit file that other lenders can see. If you make too many credit applications within a short period, it can signal to lenders that you are in financial difficulty or desperate to borrow money.
Even rejected credit applications still appear on your credit record. Spacing them out is a much smarter approach. This gives your credit score time to recover between each credit check and reduces the potential risk that lenders associate with frequent borrowing requests.
New credit should only be applied for when you genuinely need it and are confident of meeting the criteria.
5. Thin or No Credit History
It might seem strange, but having no credit history can actually lead to a low credit score. If you have never borrowed money, held a credit card or taken out a mobile phone contract, lenders have no borrowing history to assess. Without past account history, they simply cannot judge whether you are likely to repay.
This often affects young adults, people new to the UK, and anyone who has always paid for everything with cash. Opening a current account, setting up direct debits for utility bills, and using a small credit card for everyday purchases (paid off in full) are all simple ways to start building your credit file. Even a short financial history is better than none at all.

How Does a Bad Credit Score Affect You?
A bad credit score can affect almost every area of your financial life. The most obvious impact is on your ability to borrow money. Lenders are less likely to approve you for personal loans, credit cards, mortgages or car finance. If you are approved, you will probably face higher interest rates and lower credit limits than someone with a good credit score.
But a bad credit score affect goes beyond borrowing alone. It can influence your ability to land certain jobs, particularly in legal or financial services. Some other service providers, landlords, insurance companies and even mobile phone contract providers may carry out credit checks before agreeing to work with you. Even getting basic bank accounts or switching current account providers can be more difficult with poor credit.
Bad Credit Score vs Good Credit Score: What Is the Difference?
The difference between a bad credit score and a good credit score comes down to how lenders view your financial reliability. Here is a side-by-side look at how the two compare:
| Factor | Bad Credit Score | Good Credit Score |
|---|---|---|
| Loan & credit card approval | Frequently rejected or limited options | Widely approved with more choices |
| Interest rates | Higher rates to offset lender risk | Lower, more competitive rates |
| Credit limit | Lower limits on cards and overdrafts | Higher, more generous limits |
| Financial products | Restricted access to mortgages, personal loans and insurance | Full access to a wide range of products |
| Rental & employment checks | May face rejection from landlords or employers in legal or financial services | Passes most background checks with ease |
| Borrowing options | Fewer lenders willing to offer credit | Broad choice of lenders and deals |
Your credit rating can change over time. Moving from bad credit to good credit is entirely possible with consistent effort. The comparison above is not fixed. It simply reflects where your borrowing history and financial activity stand right now.
How to Fix a Bad Credit Score?
1. Pay All Bills and Credit Repayments on Time
Making payments on time is the single most powerful way to improve your credit score. This includes not just loan and credit card repayments, but also household bills, other household bills, utility bills and even utility bills paid through direct debits. Set up automatic monthly payments wherever possible so you never miss a due date.
If you are paying bills manually, add calendar reminders a few days before each deadline. Lenders place heavy weight on your payment history to decide how reliable you are. Every on-time payment strengthens your credit record, while every missed one weakens it.
2. Reduce Debt Balances and Stay Within Your Credit Limit
If you carry large balances on credit cards, overdrafts or other credit accounts, work on bringing them down bit by bit each month. Paying more than the minimum helps you clear what you owe faster and shows lenders you can manage accounts responsibly. Keep your total spending well below your agreed credit limits.
Using a small percentage of your available credit signals to credit reference agencies that you are not overly dependent on borrowing. This is known as your credit utilisation rate, and it plays a big role in how your credit score is calculated.
3. Register on the Electoral Roll and Keep Your Address Updated
Registering on the electoral register is one of the quickest and easiest ways to improve your credit score. It allows lenders to verify your identity and confirm your home address, which builds trust during credit applications. If you have recently moved, make sure your home address is updated with your bank, credit card provider and all three credit reference agencies.
An outdated address on your credit file can cause confusion and may lead to failed identity checks during credit applications.
4. Review Your Credit Report and Raise a Data Dispute if Needed
Mistakes on your credit report are more common than you might think. An incorrect past account history entry, a payment wrongly marked as missed, or a debt listed that is not yours, any of these errors can drag down your credit score unfairly.
Check your credit report regularly with each of the three credit reference agencies. If you spot an error, raise a data dispute with the relevant agency straight away. They are legally required to investigate and correct inaccurate information.
5. Space Out New Credit Applications
Every new credit application triggers a hard credit check that stays on your credit file for up to 12 months. If lenders see multiple credit checks bunched together, they may consider you a potential risk and reject your application. Space out any new credit applications by at least three to six months. Before you apply, use an eligibility checker, these run a soft search that will not negatively impact your credit score, to see how likely you are to be accepted.
Being selective with new credit protects your credit score and shows lenders you are a responsible borrower.
6. Remove Outdated Financial Links from Your Credit File
If you have ever held a joint account, shared a mortgage or taken out credit with another person, you may have a financial link on your credit file. If that person has poor credit or a bad credit rating, their behaviour can negatively impact your own score and affect your future credit eligibility.
Review your credit record for any outdated financial links. If you are no longer financially connected to someone, contact each relevant agency to request a "notice of disassociation." This removes the financial link and stops their financial activity from affecting your credit file.
Joint account holders should always be aware of this. Old address links and financial connections from past relationships or shared bank accounts can quietly pull down your credit score without you realising.
Can You Still Borrow Money with a Bad Credit Score?
Yes, you can still borrow money even with a bad credit score. While many high street banks may turn you away, there are lenders who work specifically with people who have bad credit or poor credit.
At Monixa, we consider applications from people with bad credit. You can borrow from £200 to £1,500, repaid in 4 to 6 monthly instalments with no hidden fees. Your credit score will not be affected just by applying. If approved, we send cash to your bank within 90 seconds.
Having bad credit does not mean your options have disappeared. It simply means knowing where to look for the right borrowing options.
Frequently Asked Questions About Bad Credit Scores
Does Checking My Own Credit Score Lower it?
No. Checking your own credit score counts as a "soft search" and has no effect on your credit rating. Only "hard searches," which happen when you formally apply for new credit, can negatively impact your score. You can check your credit report as often as you like without any risk to your score.
Is 500 a Bad Credit Score in the UK?
It depends on which credit reference agency you check. At Experian, a score of 500 sits in the "poor" range. At Equifax, 500 falls within the "fair" category. At TransUnion, the scale only goes to 710, so 500 would consider "poor". Always compare your credit score across all three agencies for the fullest picture of your financial health.
Do Utility Bills and Household Bills Affect Your Bad Credit Score?
Yes. Missed payments on utility bills, household bills and accounts with other service providers can appear on your credit file. Paying bills on time, including energy, water, broadband and mobile phone contracts, helps build a stronger payment history and can improve your credit score over time. Even small household bills matter when credit reference agencies are assessing your reliability.
What is the Lowest Possible Credit Score in the UK?
The lowest possible credit score is 0 in the UK. Experian scores range from 0 to 999, Equifax from 0 to 1,000, and TransUnion from 0 to 710. A score of 0 would indicate a completely blank credit file with no borrowing history or account history at all. In practice, most people with a low credit score sit somewhere between the "very poor" and "poor" bands rather than at absolute zero.
