When you apply for a mortgage, lenders are making a decision about lending you a very large sum of money over a long period. Their primary concern is risk: how likely are you to pay it back on time? One of the most important tools they use to assess this risk is your credit score.
A strong credit score can unlock better mortgage deals and lower interest rates, while a poor score can make it difficult to get a mortgage at all. Understanding what your credit score is, how it’s calculated, and how you can improve it is a fundamental step in preparing for a successful mortgage application.
What is a Credit Score?
Your credit score is a three-digit number that represents your creditworthiness. It is generated by Credit Reference Agencies (CRAs) based on the information in your credit report. The three main CRAs in the UK are:
- Experian (score out of 999)
- Equifax (score out of 1000)
- TransUnion (score out of 710)
It’s important to know that each agency uses its own scoring system, so your score will be different with each one. There is no single “universal” credit score. Lenders may check your report with one, two, or all three of these agencies.
Your credit report contains detailed information about your financial history over the last six years, including:
- Credit Accounts: Details of your mortgages, credit cards, loans, and overdrafts.
- Payment History: Whether you have made your repayments on time or have had any missed or late payments.
- Credit Searches: A record of any time a company has checked your file.
- Public Records: Information such as County Court Judgements (CCJs), bankruptcies, and whether you are on the electoral roll.
How Do Lenders Use Your Credit Score?
When you apply for a mortgage, lenders don’t just look at the three-digit score. They delve into the detail of your credit report to build a picture of you as a borrower. They are looking for answers to several key questions:
1. Are You a Reliable Borrower?
A long history of making all your payments on time is the best indicator of reliability. Missed or late payments are a major red flag.
2. How Much Debt Do You Have?
Lenders will look at your total outstanding debt and how much of your available credit you are using (known as your ‘credit utilisation’). High levels of existing debt can suggest you might be overstretched.
3. Are You Financially Stable?
Being on the electoral roll at your current address is a key sign of stability. A long history with the same bank also helps.
4. Are You Desperate for Credit?
A large number of applications for credit in a short space of time can be a warning sign to lenders.
Based on this assessment, the lender’s own internal scoring system will decide whether to accept or decline your application, and what interest rate to offer you. A stronger credit history generally leads to a lower-risk assessment and, therefore, a better mortgage deal.
Actionable Tips to Improve Your Credit Score
Improving your credit score doesn’t happen overnight, but by taking the right steps, you can make a significant difference over a period of 6-12 months. Here are the most effective actions you can take:
1. Check Your Credit Reports for Errors
Before you do anything else, get a copy of your report from all three agencies. You can do this for free through various online services. Check every single entry for mistakes. Is there a debt listed that you’ve already paid off? Is there an account you don’t recognise? If you find any errors, contact the agency immediately to have them corrected.
2. Get on the Electoral Roll
This is one of the quickest and easiest ways to boost your score. It confirms your name and address, which helps lenders verify your identity and is a strong indicator of stability. You can register to vote online in just a few minutes.
3. Make All Your Payments on Time, Every Time
This is the golden rule. Even a single missed payment can have a significant negative impact on your score. Set up direct debits for all your regular bills to ensure you never miss a payment deadline.
4. Reduce Your Existing Debt
Focus on paying down your existing debts, especially on credit cards and store cards. Lenders pay close attention to your ‘credit utilisation’. Try to keep your balance below 30% of your available credit limit on each card.
5. Avoid Making Multiple Credit Applications
Each time you formally apply for credit, it leaves a ‘hard’ search on your file. Too many hard searches in a short period can make you look desperate for credit. Use eligibility checkers, which use ‘soft’ searches, to see how likely you are to be accepted before you apply.
By taking proactive steps to understand and improve your credit score, you are making a long-term investment in your financial health. It’s a crucial part of preparing for your mortgage application and will put you in the strongest possible position to secure the keys to your new home.
