Your credit score is one of the most important numbers in your financial life. It affects your ability to get loans, credit cards, mortgages, and even some rental agreements. The good news is that, with focused effort, you can improve your score in as little as 90 days. This article provides a practical, UK-focused plan to boost your creditworthiness, helping you access better financial products and rates without waiting months or years.
Understand Your Current Score
Before you can improve your credit, you need to know where you stand. In the UK, three main credit reference agencies provide scores: Experian, Equifax, and TransUnion. Scores typically range from 0–999 (Experian) or 0–700 (Equifax), with higher scores indicating better creditworthiness.
Steps to start:
- Check your free credit reports via Experian, Equifax, or TransUnion
- Identify negative marks like missed payments or defaults
- Understand which areas have the biggest impact on your score (payment history, utilisation, length of credit)
Understanding your current position allows you to prioritise actions that will make the biggest difference in the shortest time. Without this knowledge, improvements may be slower or misdirected.
Pay Bills and Existing Debts On Time
Payment history is the most significant factor in your credit score. Even one missed payment can lower your score substantially. Establishing a clear, consistent record of on-time payments signals reliability to lenders.
Tips for staying on track:
- Set up direct debits or standing orders for bills and loan repayments
- Prioritise overdue payments to bring accounts up to date
- Keep a monthly calendar or alerts for upcoming due dates
Consistency is key. Even if you have a poor history, 90 days of perfect payment behaviour can begin to positively influence your score.
Reduce Your Credit Utilisation
Credit utilisation measures how much of your available credit you’re using. High utilisation signals risk to lenders, while keeping it low is beneficial. A simple rule is to aim for 30% or lower of your total credit limit.
Ways to improve utilisation:
- Pay down existing balances before the statement date
- Request a credit limit increase (without taking on more debt)
- Avoid opening multiple new accounts simultaneously
Lowering utilisation can have a noticeable impact quickly — sometimes within a single reporting cycle.
Correct Errors on Your Credit Report
Mistakes on credit reports are more common than many realise. Incorrect missed payments, outdated addresses, or fraudulent accounts can drag your score down unnecessarily. In the UK, disputing errors is free and can yield quick improvements once corrected.
How to correct errors:
- Check reports from all three agencies
- Flag inaccuracies via each agency’s online dispute tool
- Provide supporting evidence like statements or letters
Fixing errors not only improves your score but ensures lenders see an accurate reflection of your financial reliability.
Build Positive Credit Habits
Improving your score is not just about quick fixes; it’s also about forming good credit habits that maintain long-term strength. These habits reinforce positive behaviour in the eyes of lenders and make future credit applications smoother.
Key habits include:
- Using credit responsibly (small, manageable purchases paid off in full)
- Avoiding unnecessary hard credit searches
- Keeping older credit accounts open to lengthen your credit history
Even modest, consistent habits over 90 days can begin to influence your creditworthiness, while sustaining them ensures long-term benefit.
