Your credit history can play an important part in a mortgage application. Lenders use information from your credit report alongside your income, expenditure and wider circumstances when deciding whether they are prepared to lend to you.

If you are preparing to apply for a mortgage, checking your credit report early can give you time to identify anything that may need attention. This can be particularly useful for first time buyers who have never previously considered how their use of credit could affect a mortgage application.

There is no universal credit score that guarantees mortgage approval. Different lenders have their own criteria and ways of assessing credit history, so a score considered good by one credit reference agency does not tell you exactly how a particular mortgage lender will assess you.

Check Your Credit Report Before Applying

A useful starting point is to check the information held on your credit reports before submitting a mortgage application.

The main credit reference agencies may hold information about your borrowing and repayment history, including credit cards, loans and other credit agreements.

Your report can also contain information such as your address history and whether you are registered on the electoral roll.

Checking your reports gives you an opportunity to make sure the information recorded about you is accurate. If you find something you believe is incorrect, you can contact the relevant credit reference agency or provider to find out how it can be disputed.

It can also help you identify older accounts that you may have forgotten about or financial associations with another person that remain on your report.

Checking your own credit report does not damage your credit score, so you do not need to avoid looking at it before applying for a mortgage.

Keep Your Credit Commitments Manageable

How you manage existing borrowing can influence your credit history.

Making agreed repayments on time can demonstrate a record of managing credit. Missed or late payments, defaults and other adverse credit events can make obtaining a mortgage more difficult, depending on what happened, how much was involved and how recently it occurred.

Credit card balances can also be relevant. Regularly using a large proportion of your available credit may be viewed differently from maintaining lower balances and keeping borrowing manageable.

This does not mean you should automatically close every credit account before applying for a mortgage. The age and history of accounts can form part of your credit profile, while closing an account can also reduce the total amount of credit available to you.

Existing debts can affect mortgage affordability as well as your credit profile. Personal loans, credit card repayments and car finance may reduce the amount a lender considers affordable because these commitments already form part of your monthly expenditure.

Avoid Making Lots of Credit Applications at Once

When you apply for certain forms of credit, the provider may carry out a hard credit search. This leaves a record on your credit report that other lenders may be able to see.

Several applications within a short period can therefore become relevant when a mortgage lender reviews your credit history.

If you are preparing for a mortgage, think carefully before taking out new credit unless you need it. A new personal loan, credit card or finance agreement could affect both your credit report and the affordability calculation used for your mortgage.

This can be particularly relevant in the months leading up to buying a home. Taking out car finance shortly before applying for a mortgage, for example, introduces a new monthly commitment that a lender may need to include when assessing how much you can afford to borrow.

A mortgage Agreement in Principle can involve either a soft or hard credit search depending on the lender. Understanding which type of search will be used can be useful before making several applications with different mortgage lenders.

Build a Stronger Credit History Over Time

Improving your credit profile is not usually about finding a quick way to increase a numerical score. A consistent record of managing your finances can be more meaningful when preparing for a mortgage.

Being registered on the electoral roll at your current address can help lenders and credit reference agencies confirm your identity and address history. If you are eligible to register but have not done so, this is worth checking.

Keeping addresses consistent across financial accounts can also reduce unnecessary discrepancies in the information associated with you.

If you use credit, keeping repayments up to date and borrowing within manageable limits can contribute towards your credit history over time. Direct Debits can be useful for ensuring regular payments are not accidentally missed, provided there is enough money in the account to cover them.

You do not necessarily need to take out debt simply to improve your chances of getting a mortgage. If you have a limited credit history, the appropriate approach will depend on your circumstances rather than taking out financial products purely to generate activity on your credit report.

There is also no reliable overnight method of repairing a poor credit history. Accurate information can remain on your credit report for a period of time, so improving your position may involve demonstrating more consistent financial management as older issues become less recent.
