Credit scores play a key role in every person’s financial life, particularly if you are planning to apply for a mortgage. Mortgage lenders consider a wide variety of factors when considering whether to lend to you, such as your income, affordability, any discrepancies on your credit report and the timeline associated with these.
Each lender will have their own criteria and will assess your full financial picture, including your payment history, levels of outstanding debt and credit commitments, rather than relying on one universal score.
While it may feel daunting, understanding how your credit score works and working to improve it can make a meaningful difference to your mortgage options, interest rates and overall financial confidence.
In this article, we break down:
- What credit scores are.
- Why they are important for those wanting to get a mortgage.
- The benefits that come with having a higher score.
We will also provide you with helpful tips on how you can improve your score, helping you take positive steps towards strengthening your credit score and overall financial picture.
What is a credit score and how is it calculated?
A credit score is a number that reflects the potential risk that you pose to lenders and is based on how you have managed credit in the past. Credit scores typically range from 0 to 999, with higher scores indicating better credit health.
Your score is calculated using information from your credit report, which tracks your financial behaviour over time, including:
- Your payment history: Whether you have paid bills or other financial commitments on time.
- Credit utilisation: The amount of available credit you are using.
- Length of credit history: How long you have had credit accounts open for.
- Missed or defaulted payments: Including arrears or County Court Judgments (a legal order to repay money owed to a lender or creditor).
- Recent credit applications: Multiple applications within a short period of time can lower your score.
It is important to note that lenders asses your overall financial behaviour and not just one factor in isolation. However, certain factors, such as missed payments or CCJs, are considered more serious issues than other factors, such as overdraft usage or recent credit applications.
Your credit will also naturally fluctuate over time as your personal circumstances and financial commitments change, but maintaining positive habits will help you keep a balanced and healthy score in the long-term.
What are the benefits of having a higher credit score?
When you submit a full mortgage application, your credit score will help lenders decide whether to approve your application and on what terms.
If you have a low credit score or adverse credit history, working to improve your overall financial picture can have several practical and long-term benefits, including:
- Improved chances of approval.
A higher credit score can improve the likelihood of you being accepted for mortgages, loans or other credit by demonstrating to lenders that you are a responsible borrower.
- Access to more competitive interest rates.
Some lenders may offer more competitive rates to borrowers with stronger credit profiles, reducing the overall cost of borrowing.
- Better access to whole of market products.
A good credit score can give you access to a wider range of lenders and mortgage products, as lenders will view you as lower risk and more reliable.
- Smoother application process.
Having a strong credit profile can lead to fewer checks, faster approvals and less back-and-forth communication during applications.
- Improved financial confidence.
Having a healthy credit profile can make major financial decisions, such as buying a home, feel more manageable and less stressful, particularly for first-time buyers.
How can I improve my credit score?
Improving your credit score is not about quick fixes but involves compounding actions and demonstrating responsible financial behaviour over time. Lenders want to see that you can manage credit consistently and reliably, particularly when assessing you for a mortgage.
Small, consistent improvements can have a meaningful impact when maintained over several months.
The most effective ways to improve your credit score include:
- Pay all bills, subscriptions and credit commitments on time.
Your payment history is one of the most influential factors in your credit score. Consistently paying financial commitments (e.g. credit card balances, loans, utility bills and phone contracts) on time demonstrates to lenders that you can manage repayments reliably.
- Utilise available credit strategically.
Using a credit card for small, everyday purchases, such as groceries or fuel, and repaying the balance in full and on time each month can help demonstrate responsible credit management. Over time, this consistent behaviour may have a positive impact on your credit score.
- Keep credit card balances low.
If applicable, try to use your available credit card limit minimally. High balances can indicate financial strain, even if you pay on time. Whereas low utilisation demonstrates controlled credit use.
- Limit new credit applications.
Making multiple credit applications in a short period of time can raise red flags for lenders. Spreading out applications helps protect your score in case of rejections and shows stable borrowing behaviour.
- Register on the electoral roll.
Being registered on the electoral roll at your current address helps lenders verify your identity and stability, which can positively influence your credit profile.
- Check your credit report regularly.
Reviewing your credit report allows you to spot potential errors, outdated information or fraudulent activity.
If you identify an inaccuracy (e.g. a missed payment) on your report, contacting your credit reference agency (e.g. TransUnion, Experian, or Equifax) is the best course of action to get the issue resolved. If possible, providing documents or statements that support your claim of the error can also help get things resolved, however, this will be determined by your credit reference agency.
Resolving errors can help prevent your score from being unfairly affected.
- Maintain older credit accounts where appropriate.
A longer credit history can work in your favour, as it shows experience managing credit over time. However, it is important to use credit within your financial means and stay comfortably within your available credit limit.
High balances or missed payments can negatively affect your credit profile and may result in interest or fees being charged, depending on the card provider’s rates.
How long should I spend on improving my score?
Your credit score is something that should be maintained and improved consistently throughout your lifetime. This ensures your credit profile remains healthy and that any areas for improvement can be monitored and amended.
However, it is recommended to check your credit score at least 6 months prior to applying for a mortgage to ensure you have ample time to make improvements or address any errors. This will help increase your chances of approval and securing a better mortgage.
Credit Score FAQs
- Is there a minimum score required for a mortgage?
There is no fixed credit score required to get a mortgage; however, a lower score can lead to more stringent conditions, less favourable offers and can make approval more challenging as lenders prefer to see evidence of responsible borrowing.
In contrast, a higher credit score can lead to more favourable mortgage terms, such as lower interest rates and smaller deposit requirements, making it highly beneficial to work towards improving your score if it is lower than desired.
- What if I have little or no credit score?
If you have little or no credit score, this does not automatically mean rejection. While main high street lenders may be more reluctant to lend to those with lower credit scores, there are specialist lenders who focus on supporting individuals with adverse or no credit history.
Working alongside one of our mortgage advisers can help you understand your options and find lenders bested suited to your personal circumstances.
How can I check and monitor my credit score?
Tools such as Experian, Equifax and TransUnion can help you monitor and improve your score by allowing you to regularly check your credit report and provide helpful feedback on areas that may need improvement.
These are also the most common providers which lenders will use when assessing your application. However, each agency may use a different scale to determine your score, meaning your score may vary across providers.
It is important to be aware that your score will naturally fluctuate over time as your circumstances and financial commitments change. However, managing your finances and credit responsibly will help ensure you do not negatively impact your score or that any one-off fluctuations have time to stabilise.
