Introduction
Having a strong credit score in 2025 is more important than ever, especially if you’re planning to apply for car finance in the UK. With the cost of living still impacting many households and lenders becoming more cautious, your credit history can play a crucial role in the deals you’re offered.
Whether you’re exploring car finance with bad credit or aiming to qualify for the best interest rates, taking steps to improve your credit score can open up an entire world of better borrowing options. In this detailed guide, put together by our car buying experts, we’ll walk through the smartest and most effective ways to boost your credit score, increase your eligibility, and secure the best car finance deals in the UK this year.
How UK Credit Scoring Works
Understanding how credit scoring works in the UK is the first step towards improving your creditworthiness, especially if you’re planning to apply for car finance. In 2025, lenders continue to rely heavily on your credit report when determining whether to approve a loan and what terms to offer. A strong credit score doesn’t just increase your chances of approval either; it can also help you qualify for lower interest rates and better finance deals (saving you money).
In the UK, your credit score is assessed and maintained by three main Credit Reference Agencies (CRAs): Experian, Equifax, and TransUnion. While each agency uses its own scoring system, they all evaluate similar key factors that reflect your financial behaviour:
- Payment history – Whether you’ve made past credit repayments on time
- Credit utilisation – The percentage of your available credit that you’re using
- Length of credit history – How long your credit accounts have been open
- Types of credit used – A mix of credit cards, loans, and other credit products
- Recent credit activity – The number of recent credit applications or ‘hard’ searches
What’s a Good Credit Score in the UK
Each CRA assigns you a credit score based on this data, and lenders may use one or more of these scores when reviewing your car finance application. Because scoring models differ slightly between agencies, your score may vary depending on where you check it. Typically, the data below indicates what constitutes a ‘good’ and ‘great score’ for the three main agencies:
- Experian: 0-999 (Good: 881-960, Excellent: 961-999)
- Equifax: 0-1000 (Good: 531-670, Excellent: 671+)
- TransUnion: 0-710 (Good: 566-603, Excellent: 604-710)
How to Review Your Credit Report
Before taking steps to try and improve your credit score, you need a clear understanding of your current position. The 2025 Consumer Credit Act amendments have strengthened your right to access your credit information free of charge.
Start by obtaining comprehensive reports from all three major CRAs. Each provides a free statutory report, while services like ClearScore, Credit Karma, and Experian’s own platform offer ongoing free access with varied features.
How to update your Credit Report Information
When reviewing your report, it’s really important that you clarify that all your details are correct, start by:
- Verifying personal information (name, address, electoral registration)
- Checking for inaccurate payment records or defaults
- Looking for unfamiliar accounts that might indicate fraud
- Reviewing financial associations that could be affecting your score
- Noting the age and types of your credit accounts
According to a recent Which? study, approximately 32% of UK consumers in the last five years discovered significant errors on their credit reports. These errors, when corrected, resulted in an average score improvement of 73 points- potentially enough to move you into a better lending category.
If you spot inaccuracies, raise a dispute immediately through the relevant CRA’s formal process. Under current regulations, they must investigate and respond within 28 days.
Will Making Payments on Time Improve my Credit Score?
The short answer is yes. Making payments on time remains the single most influential factor in UK credit scoring models. The 2025 credit assessment algorithms place lots emphasis on payment consistency, with even a single missed payment potentially affecting your score for up to six years.
To ensure you’re always able to make payments on time, we advise:
- Setting up Direct Debits for all regular payments to eliminate the risk of forgetfulness
- Ensuring sufficient funds are available in your account on payment dates
- If facing temporary financial difficulty, contact creditors proactively to arrange payment plans
- Consider using the ‘payment holiday’ features now offered by many lenders during genuine hardship
- Reviewing statements regularly to catch and query any unexpected charges promptly
Research by the Financial Conduct Authority shows that consumers who maintain perfect payment records for 12 consecutive months see an average credit score increase of 42 points (potentially moving you from ‘fair’ to ‘good’ in many scoring models).
For those with historical missed payments, the impact diminishes over time so try not to be too disheartened if this is currently affecting your profile. Instead, focus on establishing a solid recent payment history, as credit algorithms typically weight recent behaviour more heavily than past issues.
Will Reducing Balances Improve my Credit Score?
In short- yes, absolutely. Paying down your existing debts is one of the most effective ways to boost your credit score, often delivering results more quickly than other credit-building strategies.
When you reduce your outstanding balances, particularly on credit cards and overdrafts, you’re directly improving something called your “credit utilisation ratio” (CUR): a financial term that sounds complicated but is actually quite straightforward.
Think of your credit utilisation ratio as the relationship between how much credit you’re currently using versus how much you have available. If you have credit cards with combined limits of £10,000 and you’ve spent £7,000 across them, your utilisation sits at 70%. From a lender’s perspective, this suggests you’re heavily reliant on borrowed money, potentially raising concerns about your financial stability.
Lenders in 2025 typically prefer to see this ratio below 30% and keeping your balances below this threshold signals that you’re managing your finances comfortably without maxing out your available credit.
Here’s how you can improve your CUR:
- Focus on paying down your highest-interest debts first while maintaining minimum payments on others
- Consider transferring balances to 0% interest cards to help clear debt more efficiently
- Keep older credit accounts open even after paying them off- this preserves your total available credit
- If you’ve demonstrated good payment history, request modest credit limit increases, put consider the interest rates
- Spread necessary balances across multiple cards rather than concentrating debt on a single card
Will Applying for Credit Impact my Credit Score?
Again the simple answer to this question is yes. Every credit application triggers what’s known as a “hard search” on your credit file, temporarily lowering your score. Multiple applications in a short period can significantly impact your creditworthiness, as they could indicate financial desperation to potential lenders.
If you’re thinking of applying for car finance, follow the following tips before you start the process:
- Research lenders’ criteria thoroughly to target appropriate providers
- Space applications at least three months apart where possible
- Consider using a specialist broker who can match you with suitable lenders
- Avoid making other credit applications when planning car finance
Many car finance comparison sites now offer pre-approval tools that perform soft searches across multiple lenders, providing personalised quotes without affecting your credit score.
How to Build Credit History
Lenders favour applicants with established, diverse credit histories demonstrating responsible management over time. If you’re new to credit or rebuilding after difficulties, consider these top tips for building your credit history:
- Apply for a credit-builder card with a small limit, using it for regular small purchases and paying in full monthly
- Consider a small personal loan repaid over 12-24 months
- Explore options like Loqbox or LOQD that convert regular savings into credit-building opportunities
- Add utility accounts and mobile phone contracts to your credit file through services like Experian Boost
- Become an authorised user on a family member’s well-managed credit card
If you’re looking to build your credit history for a car finance application specifically, we also recommend calculating your estimated car finance payments using a car finance calculator as it gives you a helpful forecast of predicted payments.
Financial Associations & Credit Score Impact
Your credit file doesn’t exist in isolation, it’s connected to others through what lenders call “financial associations.” These connections form whenever you share financial products with someone else, such as joint bank accounts, mortgages, or even household utility bills.
What many people don’t realise is that these associations continue to influence your credit score long after relationships end. If you’ve previously shared finances with a partner, family member, or housemate, their credit behaviour could still be affecting your car finance options in 2025.
When you apply for car finance, lenders don’t just scrutinise your credit history, they also peek at the financial conduct of anyone linked to you. If your former flatmate from three years ago has missed payments or defaulted on loans, their financial missteps might be unfairly dragging down your credit score.
Fortunately, addressing these outdated associations is reasonably straightforward. Start by requesting your full credit reports from all three major agencies and carefully review the “financial associations” section. You might be surprised to discover links to people you’d almost forgotten about. If you spot associations that no longer reflect your current financial relationships, you can request a “financial disassociation” from each credit reference agency.
Does Registering on the Electoral Roll Improve Credit Scores?
Registering to vote might seem completely unrelated to car finance, but it’s actually one of the quickest and easiest ways to enhance your creditworthiness. When you register on the electoral roll (or electoral register as it’s sometimes called), you’re doing more than just securing your right to vote—you’re providing official verification of your name and address that lenders rely on heavily.
From a lender’s perspective, seeing you on the electoral roll at your current address provides reassurance about your stability and identity. It answers fundamental questions they need to address: Are you who you claim to be? Do you actually live where you say you do? How long have you been at this address? These verification points form the foundation of their risk assessment.
Registering takes just five minutes online through the government’s website, but the impact on your credit score can be significant. Recent data from Equifax suggests that being properly registered can boost your score by up to 50 points (potentially moving you into a more favourable lending category).
How to monitor your Credit Score
Keeping a close eye on your credit score is one of the easiest ways to stay on top of your financial health- especially if you’re working towards getting approved for car finance. Regular monitoring helps you spot any changes, catch mistakes early, and track your progress over time.
Your credit score can change from month to month based on how you manage your accounts, so it’s a good habit to check it regularly. You won’t harm your score by checking it yourself, and most services now make it simple to do so for free.
There are several useful tools and apps that allow you to view your credit report and get updates:
- ClearScore – Uses Equifax data and provides a score out of 1,000
- Credit Karma – Based on TransUnion data, offers insights and tips
- Experian – Offers free access to your score and report with a basic account
- MoneySavingExpert’s Credit Club – Free tool using Experian data with added features like comparisons and eligibility checks
Professional Credit Score Improvement Advice
If you’re struggling with debt, missed payments, or a low credit score, it can be helpful to speak to someone who understands how to get things back on track. Seeking professional advice doesn’t mean you’ve failed: it just means you’re taking control of your financial situation.
There are trusted organisations and charities in the UK that offer free, confidential advice for anyone facing financial difficulties. These include:
- StepChange Debt Charity
- Citizens Advice
- National Debtline
Advisors can help you understand your credit report, deal with problem debts, and create a manageable plan to improve your credit over time. If you’re applying for car finance like PCP with bad credit, getting guidance can also help you understand your options and avoid high-cost deals that could make things worse.
