Planning to move home often involves big financial decisions, and your credit score sits right at the heart of them. It is not just a number; it is a key indicator of your financial reliability, essential for securing everything from mortgages to competitive rates on other financial products. Your credit score plays a significant role in whether you can get a mortgage and the interest rate you will pay. A strong credit score signals to lenders that you are a reliable borrower, making the entire home moving process smoother.

Here are the key takeaways to help you improve your credit score:

  • Understand your report: Regularly check your credit report for inaccuracies and understand what factors influence your score, so you are better prepared for a mortgage application.
  • Register to vote: Being on the electoral roll is a simple yet powerful way to verify your identity and boost your score.
  • Pay bills on time: Consistency in paying all your bills, especially credit agreements, is fundamental to a healthy credit history and can help when applying for a mortgage.
  • Keep your credit use low: Keep your credit card balances low relative to your credit limits to demonstrate responsible borrowing.
  • Limit new applications: Too many credit applications in a short period can negatively impact your score.

What is a credit score and why is it important for moving home?

A credit score is a number that represents your financial trustworthiness to lenders. It is a summary of your credit history, indicating how reliably you manage debt and make repayments. Each credit reference agency measures and scores this differently, so you may see different scores across the main credit reference agencies.

For anyone looking to move home, a good credit score is important. Lenders, including mortgage providers, use your credit score to assess the risk of lending you money. A higher score can lead to better mortgage deals, lower interest rates, and a smoother application process, directly impacting your ability to buy a new home.


How can I check my credit score for free in the UK?

You can check your credit score for free through several credit reference agencies in the UK. These agencies collect and maintain your credit information.

In the UK, the three main credit reference agencies are Experian, Equifax, and TransUnion. Each agency provides a statutory credit report, which you are legally entitled to access for free. Services like ClearScore (using Equifax data), Credit Karma (using TransUnion data), and MSE Credit Club (using Experian data) offer free access to your credit score and report, often with regular updates and insights. Checking your own credit report does not negatively affect your score, and it can help you stay ready for a mortgage application.


What are the top 10 tips to improve your credit score?

Improving your credit score is a marathon, not a sprint, but consistent effort in key areas can yield significant results. Focus on these practical steps to strengthen your financial standing and support your mortgage application.

1. Why is registering on the electoral roll important for your credit score?

Registering on the electoral roll is a straightforward step that helps lenders confirm your identity and address. This verification is an important part of their assessment and can support a mortgage application.

When you apply for credit, lenders need to be sure you are who you say you are and that you live where you say you do. Being on the electoral roll, also known as the 'register of electors', provides a reliable public record of your address. This makes it easier for credit reference agencies to match your details, adding weight to your credit file and making you appear more stable and trustworthy to potential lenders. You can register to vote on the GOV.UK website.

2. How can paying bills on time help build a credit score?

Consistently paying all your bills on or before their due dates demonstrates responsible financial behaviour. This is one of the most impactful ways to build and improve your credit score, which can help when you apply for a mortgage.

Every payment you make, from utility bills and mobile phone contracts to credit card statements and loan repayments, contributes to your credit history. Late or missed payments are recorded and can severely damage your score, signalling to lenders that you might be a high-risk borrower. Setting up direct debits or standing orders for all your regular payments can help ensure you never miss a due date.

3. What is credit utilisation and how does it affect your credit rating?

Credit utilisation is the amount of credit you use relative to your total available credit. Keeping this ratio low is a key indicator of responsible credit management.

Lenders prefer to see that you are not relying heavily on your available credit. A high credit utilisation ratio (e.g. using 80% of your credit card limit) can suggest financial strain, even if you make payments on time. Experts generally recommend keeping your credit utilisation below 30% across all your credit accounts. For example, if you have a credit card with a £1,000 limit, try to keep your balance below £300 to present a stronger case for a mortgage application.

4. Why should I limit new credit applications?

Making multiple credit applications in a short period can raise red flags for lenders and negatively impact your credit score. Each application typically leaves a 'hard search' mark on your credit file, which can affect how a mortgage application is viewed.

While checking your own credit report (a 'soft search') does not affect your score, hard searches are visible to other lenders. A flurry of hard searches suggests you might be desperate for credit or struggling financially, which can make you seem riskier to lenders. Only apply for credit when you genuinely need it and have a strong chance of approval. If you are exploring mortgage options, consider using a mortgage broker who can often perform soft searches initially.

5. How does closing old credit accounts impact your credit score?

Closing old credit accounts, especially those with a long, positive payment history, can sometimes have a negative effect on your credit score. It is often better to keep them open and unused.

An older credit account with a good payment history contributes positively to the 'age of your credit history', which is a factor in your score. Closing it can reduce the average age of your accounts and also decrease your total available credit, potentially increasing your credit utilisation ratio if you have other active accounts. If you have an old, unused credit card, consider keeping it open and making a small purchase occasionally, paying it off in full, to maintain an active, positive history for mortgage purposes.

6. Can a credit builder credit card help improve my credit?

Yes, a credit-builder credit card is designed for people with little to no credit history or those looking to repair a poor credit history. It offers a controlled way to demonstrate responsible borrowing.

These cards typically have lower credit limits and higher interest rates, making them suitable for small, manageable purchases that you can pay off in full each month. By consistently making on-time payments and keeping your use low, you can gradually build a positive credit history. This is particularly helpful for first-time buyers who need to establish a credit footprint before applying for a mortgage.

7. Why is it important to check your credit report for errors?

Your credit report is compiled from various sources, and mistakes can happen. Errors on your report could unfairly lower your credit score and hinder your ability to secure credit.

Common errors include incorrect personal details, accounts you do not recognise, or outdated information. Regularly checking your reports from all three credit reference agencies (Experian, Equifax, TransUnion) allows you to spot discrepancies. If you find an error, you have the right to dispute it with the agency, which is legally obliged to investigate. Correcting these inaccuracies can lead to an immediate boost in your score.

8. How can managing existing debts effectively improve your credit score?

Actively managing and reducing your existing debts, particularly high-interest ones, shows lenders you are in control of your finances. This positive behaviour is reflected in your credit score.

Prioritising debt repayment, especially on credit cards or loans with high interest rates, not only saves you money but also reduces your overall debt burden. This can improve your credit utilisation ratio and demonstrate financial discipline. Consider debt consolidation if appropriate but be mindful of the impact on your credit file. MoneyHelper, a service backed by the UK government, offers free and impartial advice on managing debt.

9. What is the role of financial associations in credit scoring?

Financial associations occur when you share a financial product, such as a joint bank account or mortgage, with another individual. Their credit behaviour can then affect your own.

If you are financially associated with someone who has a poor credit history, it could potentially affect your ability to get credit, even if your own record is spotless. It is wise to be aware of any financial associations on your credit report and consider severing them if they are no longer relevant, for example, after a relationship ends. You can request a 'notice of disassociation' from credit reference agencies to protect your mortgage application.

10. Should I consider long-term financial stability for my credit score?

Yes, building a strong credit score is not just about short-term fixes; it involves demonstrating consistent, long-term financial stability. Lenders look for a pattern of responsible behaviour over time, especially when assessing a mortgage application.

This means maintaining stable employment, having a consistent address, and avoiding frequent changes to your financial habits. A long history of managing credit well, coupled with a stable lifestyle, paints a picture of reliability. This is particularly reassuring for mortgage lenders, who are committing to a significant long-term loan.
