What is my credit score, and how does it impact my borrowing options?
26th March 2026
By Simon Carr
In the UK financial landscape, your credit score acts as a vital numerical summary of your borrowing history, influencing nearly every major financial decision you make—from securing a mortgage to taking out a simple phone contract. This score is what lenders use to assess your reliability and determine the risk associated with lending you money, directly affecting the interest rates and terms you are offered.
TL;DR: Your credit score is a numerical representation of your financial behaviour, calculated by Credit Reference Agencies (CRAs). A higher score signals reliability to UK lenders, which typically results in better borrowing terms, lower interest rates, and a wider range of product choices, while a low score may limit your options or increase costs significantly.
Understanding What is My Credit Score, and How Does It Impact My Borrowing Options?
Whether you are planning to purchase a property, refinance an existing loan, or seek essential finance through products like bridging loans, understanding your credit score is the first crucial step. Your score is not static; it constantly changes based on your recent financial activity. Lenders use this data to decide if you are a desirable borrower.
What Exactly is a UK Credit Score?
A credit score is a three-digit number designed to predict the likelihood of you repaying borrowed money. In the UK, scores are compiled and maintained by three main Credit Reference Agencies (CRAs): Experian, Equifax, and TransUnion (formerly Callcredit).
It is important to note that you do not have one universal score. Each CRA uses a slightly different scale and calculation method, meaning your score can vary between agencies. For example, a score considered “excellent” by Experian might be in a different tier according to Equifax.
The information held on your credit report, which generates your score, includes details about:
- Your current and past addresses.
- Your payment history for credit cards, loans, mortgages, and utility bills.
- Any county court judgments (CCJs) or bankruptcies.
- Details of financial connections (people you share joint accounts with).
- Your current credit utilisation (how much credit you use versus your available limit).
How is Your Credit Score Calculated?
Lenders are looking for consistency and stability. While the exact weighting used by each CRA is proprietary, certain factors consistently have the largest influence on whether your score is high or low.
Payment History (The Most Important Factor)
Your track record of paying back credit on time carries the most significant weight. Late payments, missed payments, defaults, and arrears signal a higher risk. Even one missed payment can negatively impact your score, especially if it leads to a default registered on your file.
Credit Utilisation
This is the percentage of your total available credit that you are currently using. If you have a £5,000 credit card limit and you are regularly using £4,500 of it, your utilisation is 90%. Lenders prefer to see low utilisation—ideally below 30%—as high utilisation suggests you might be relying too heavily on borrowed money.
Length of Credit History
The longer you have successfully managed credit, the better. Older accounts (like a long-held credit card or mortgage) demonstrate long-term reliability. Closing older accounts unnecessarily can sometimes reduce the average age of your credit history, which may slightly impact your score.
Credit Searches and Applications
There are two types of searches on your file: soft searches and hard searches. Soft searches (often used for initial eligibility checks or when you check your own file) do not affect your score. Hard searches occur when you formally apply for credit. Too many hard searches in a short period (e.g., six months) can make lenders cautious, signalling that you are desperate for credit.
Electoral Roll Registration
Being registered on the electoral roll is a key factor for lenders to verify your identity and address quickly. Failure to register can lead to delays in applications or even application refusal.
The Impact on Your Borrowing Options
The impact of your credit score is direct and pervasive. It influences three core areas of borrowing:
1. Approval Odds
If your credit score is low (often classified as “poor” or “fair”), many mainstream lenders may decline your application instantly. High street banks typically have strict automated scoring criteria. A strong credit score significantly increases the probability of receiving an offer.
2. Interest Rates and Costs
This is where the financial difference is most noticeable. Borrowers with excellent credit are considered low-risk and are therefore offered the lowest possible interest rates (the Representative APR). Borrowers with lower or “adverse” credit scores are charged higher rates to compensate the lender for the increased risk.
Over the lifetime of a large loan, like a mortgage or a specialist property bridging loan, a difference of just 1% in the interest rate can equate to thousands of pounds in extra repayment costs.
3. Product Availability and Flexibility
A good credit score opens up a broader range of financial products, including 0% balance transfer credit cards, high-LTV (loan-to-value) mortgages, and flexible bridging finance options. If your score is low, you may be restricted to specialist or subprime lenders who cater specifically to adverse credit history, often resulting in less favourable terms or higher fees.
When dealing with secured loans, such as certain complex property finance options, the collateral (your property) provides security for the lender. However, even with collateral, a poor credit history can lead to a more conservative LTV ratio or stricter conditions regarding exit strategies.
Important Risk Warning: Whether you have excellent credit or adverse credit, if you secure finance against your property, your property may be at risk if repayments are not made. Potential consequences of default include legal action, repossession, increased interest rates, and additional charges.
How to Improve Your Credit Score
Improving your score takes time and consistent positive financial behaviour, but even small changes can help:
- Pay Everything on Time: Set up direct debits for all utility bills, credit cards, and loan repayments to ensure you never miss a due date.
- Reduce Utilisation: Pay down your credit card balances. Aim to keep your usage below 30% of your maximum limit across all cards.
- Register on the Electoral Roll: This is a simple step that significantly helps identity verification.
- Limit Applications: Avoid making multiple applications for credit in a short period. If you are shopping around, use eligibility calculators that perform only soft searches.
- Check for Errors: Your credit report is managed by CRAs, and errors can happen. If you spot incorrect information, contact the relevant CRA immediately to have it rectified. For guidance on correcting errors, you can visit the MoneyHelper website.
Accessing Your Credit Report and Score
Knowing exactly what information lenders are seeing is paramount. By checking your own report regularly, you can monitor for fraudulent activity or administrative mistakes. Checking your own file is a soft search and will not harm your score.
You have a legal right to access the data held about you by UK CRAs. You can often obtain this information directly from the agencies themselves, or through partner services.

People also asked
What is considered a “good” credit score in the UK?
While the exact definitions vary by agency, generally, scores above 880 (out of 999 for Experian) or in the “Excellent” tier for other agencies are considered good. This level typically grants you access to the most competitive financial products and lowest interest rates available.
How long do negative marks (like defaults) stay on my credit report?
Most adverse information, including defaults, County Court Judgments (CCJs), and bankruptcies, will typically remain on your UK credit file for six years from the date the mark was registered, regardless of whether the debt has been fully settled in the interim.
Is a soft search different from a hard search?
Yes. A soft search is a preliminary check, usually used for eligibility or identity verification, and is only visible to you. A hard search is performed when you apply for credit and is visible to other lenders, potentially impacting your score if you have too many in a short period.
Does using my overdraft facility affect my score?
Using your arranged overdraft occasionally should not damage your score, provided you manage it responsibly and do not exceed the limit. However, consistently being close to or over your agreed limit will register as high credit utilisation and could negatively affect your score.
Should I close old credit accounts once they are paid off?
Generally, it is advisable to keep old, well-managed accounts open, even if you are not using them. They contribute positively to the “length of credit history” factor and provide a higher total available credit limit, which helps keep your credit utilisation percentage low, even if you have a balance on another card.
Understanding and proactively managing your credit score is fundamental to achieving financial success in the UK. A strong score empowers you, providing competitive access to loans, mortgages, and specialist finance, ensuring you are not unnecessarily paying premium interest rates for the life of your borrowing.
