Your credit score is based on your credit history and the information in your credit report. It can change over time depending on how you manage credit.
Lenders use your credit history, not just your score, when making decisions. A stronger credit profile may improve your chances of approval and better credit terms.
Whether you are building credit history for the first time or improving your credit report, there are practical steps that can help over time.
This page explains how to build and improve your credit score in the UK over time.
Why Your Credit Score Matters
Your credit score helps lenders understand your credit history and how you manage credit accounts.
Credit reference agencies collect this information and build your credit report. The main credit reference agencies in the UK are:
Experian
Equifax
TransUnion
Lenders use credit reference agency data alongside their own checks when assessing applications.
A higher credit score may improve your chances of approval for products such as:
Mortgages
Personal loans
Credit cards
Car finance
Mobile phone contracts
Rental agreements
How To Help Improve Your Credit Score
1. Register on the Electoral Roll
Registering helps credit reference agencies confirm your identity and address history.
If you are not registered, some lenders may find it harder to confirm your details when assessing an application.
You can register to vote online at GOV.UK
2. Keep Your Address Details Consistent
Moving home frequently does not automatically lower your credit score.
However, inconsistent address information can make identity checks more difficult.
To keep your credit report accurate and up to date, update your details with credit providers and on the electoral roll when you move.
3. Review Your Credit Report
Even small errors on your credit report could affect your ability to access credit.
Check your report regularly to make sure:
Your personal details are correct
Account information is accurate
Closed accounts are marked correctly
There are no unfamiliar searches or accounts
At CreditKnowledge, we use TransUnion to provide you with free access to your latest credit information and help you monitor changes over time.
If you notice incorrect information, you can raise a dispute directly through your CreditKnowledge account.
This allows the information to be reviewed with the relevant lender or provider.
Regular checks may also help you spot fraud or identity theft earlier.
Check your credit report for free and raise disputes directly through your account if something doesn’t look right.
4. Watch Out for Fraud and Identity Theft
If you notice unfamiliar accounts, searches or applications on your credit report, it could be a sign of identity fraud.
If you think your information has been used fraudulently:
Contact your bank or lender immediately
Report lost or stolen documents
Review your credit report carefully
Keep records of all communications
Report fraud to Action Fraud
You may also wish to consider Protective Registration through Cifas, which places additional checks against applications made in your name.
5. Check Your Financial Associations
Financial associations are usually created when you apply for joint credit with another person. If the person you are financially linked to has a poor credit history, some lenders may consider this during an application.
Make sure any financial associations listed on your credit report are accurate.
6. Pay Your Bills on Time
Making payments on time is one of the most important factors in building a strong credit profile.
Late or missed payments may remain on your credit report for up to six years and could negatively affect future applications.
To help avoid missing payments, consider setting up Direct Debits for your accounts.
7. Avoid Making Multiple Credit Applications in a Short Time
When you apply for credit, lenders may carry out a hard search on your credit report.
A small number of hard searches is normal, but multiple applications within a short period may suggest financial pressure to lenders.
If you have recently been declined for credit, consider waiting before applying again.
8. Use Eligibility Checkers Before Applying
Eligibility checkers can help you understand your likelihood of approval before making a full application, reducing unnecessary hard searches and avoiding making applications that are unlikely to be approved.
These checks usually use a soft search, so they do not affect your credit score and are only visible to you.
Check Your Credit Card Eligibility
9. Use Credit Responsibly
Using credit and repaying it on time helps demonstrate responsible credit behaviour and may help strengthen your credit profile over time.
10. Keep Credit Utilisation Low
Credit utilisation refers to how much of your available credit you are using.
As a general guide, some experts recommend keeping credit utilisation below 30%.
For example:
If your total credit limit is £5,000, try to keep balances below £1,500 where possible.
11. How Credit History Can Be Built Over Time
If you have little or no credit history, having accounts in your name and repaying on time may help improve your credit score over time.
Examples include:
Utility bills
Broadband contracts
Mobile phone contracts
What Affects Your Credit Score?
Your credit score is influenced by your credit history, including:
Payment history
Credit utilisation
Credit applications (hard searches)
Length of credit history
Financial associations
Electoral roll registration
Public records (e.g. CCJs or bankruptcies)
Credit reference agencies may weigh these factors differently.
How Long Does It Take to Improve Your Credit Score?
Building your credit score and credit history takes time and consistent behaviour.
Some changes may affect your credit score within weeks or months, such as reducing credit utilisation. Other information, like missed payments, can remain for up to six years.
To build your credit history and score, focus on:
Paying bills on time
Managing credit accounts responsibly
Avoiding unnecessary applications
Checking your credit report regularly to monitor changes
Frequently Asked Questions
How can I improve my credit score quickly?
There is no instant way to improve your credit score. Improving your credit history takes time, but checking your credit report and paying on time may help over time.

What is a good credit score in the UK?
Each credit reference agency uses a different scoring system, so there is no single UK score.
Does being on the electoral roll improve my credit score?
Being on the electoral roll helps lenders confirm your identity and address history, which may support credit applications and improve your credit profile accuracy.

Accurate missed payments cannot usually be removed and may remain on your credit report for up to six years. However, incorrect information can be disputed with the lender or credit reference agency.
