What Is a Soft Credit Check?
A soft credit check is a preliminary search that allows a lender or broker to review basic credit information without leaving a visible mark on your file. Soft checks are only visible to you when you view your own credit report. They are not visible to other lenders and do not affect your credit score.
Soft checks are commonly used at the early stages of the mortgage process, including when obtaining a decision in principle from certain lenders or when a broker reviews your credit profile to assess suitability. They provide an initial indication of your position without committing to a formal application.
Not all lenders use soft checks at the decision in principle stage. Some lenders carry out a full hard search even at this early point, which is why understanding the lender’s approach before applying matters. A broker can advise which lenders use soft checks for initial assessments and which do not, helping you avoid an unnecessary footprint before you are ready to proceed.
What Is a Hard Credit Check?
A hard credit check is a full search of your credit file that is visible to other lenders. It leaves a footprint on your report that shows a credit application has been made. Hard checks are standard at the full mortgage application stage and are a necessary part of the underwriting process.
Each hard search is recorded on your credit file. Credit searches typically remain visible for one to two years depending on the credit reference agency. Experian retains search footprints for around twelve months, while TransUnion retains them for up to two years.
A single hard search for a mortgage application is normal and unlikely to cause concern. The issue arises when multiple hard searches appear on your file in a short period, as this can signal financial difficulty or suggest that applications have been declined elsewhere.
When Lenders Run Credit Checks During the Mortgage Process
Lenders typically run credit checks at two main points during a mortgage application:
• Decision in principle stage. Some lenders carry out a soft search at this point, others a hard search. A decision in principle gives an initial indication that the lender may be willing to lend, but it is not a formal mortgage offer and does not guarantee approval.
• Full application and underwriting stage. A hard credit check is standard here. The lender reviews your full credit history alongside income, outgoings and affordability. Some lenders may also carry out a further check closer to completion to confirm your financial position has not changed since the original application.
Understanding when these checks happen helps you manage the process and avoid unnecessary searches. If you are at the early stages and want to explore options without committing to a full search, the mortgage application guide covers the steps from initial enquiry through to formal offer.

What Lenders Look for in Your Credit File
When a lender reviews your credit file, they are assessing your track record of managing credit and whether you represent an acceptable level of risk. The main areas they typically review include:
• Payment history on existing credit accounts, including any missed or late payments
• Outstanding balances and the level of credit currently in use
• County court judgments, defaults, individual voluntary arrangements or bankruptcy orders
• The number and type of credit searches already on your file
• Electoral roll registration and address history
• Financial associations with other individuals
Most negative credit information is retained on your file for six years from the date of the event. After this period, defaults, county court judgments and similar entries should be removed automatically by the credit reference agencies.
It is worth noting that lender criteria vary. What one lender considers a reason to decline may not be an issue for another. If your credit file shows adverse history, the bad credit mortgages guide explains how different lenders approach applications with defaults, missed payments and other credit events.
How Multiple Credit Searches Affect Your Application
Multiple hard credit searches in a short period can reduce your credit score and may make lenders more cautious. From a lender’s perspective, several recent hard searches can suggest that you have been applying for credit elsewhere and may have been declined, even if that was not the case.
This is one reason why submitting speculative applications to several lenders directly can be counterproductive. Each application may trigger a hard search, and the cumulative effect can weaken your credit profile at the point when you most need it to be strong.
If your application has been declined and you are unsure of the reason, the declined applications guide explains the common causes and what steps to take next. It is usually better to understand why a decline occurred and address the issue before reapplying, rather than submitting further applications immediately.
Checking your own credit report before applying does not leave a hard footprint and does not affect your score. You can download your credit report through a multi-agency service to see what lenders are likely to find before any formal application is made.
How a Broker Helps Manage Credit Searches
One of the practical advantages of using a broker is that a broker can research lender criteria and match your profile to suitable lenders before any formal application is submitted. This targeted approach reduces the number of hard searches on your file because you are only applying to lenders whose criteria your case is likely to meet.
A broker can also advise whether your credit file needs attention before applying. In some cases, straightforward steps such as correcting errors, reducing credit utilisation or updating your electoral roll registration can strengthen your position. The improve your credit score guide covers practical steps you can take and how long they typically take to show on your file.
By approaching the right lender first time, you reduce unnecessary footprints and give your application the strongest possible starting position. Lender criteria, rates and product availability vary and can change, so the route that works for one borrower may not suit another.

FAQs
1. Does a decision in principle affect my credit score?
It depends on the lender. Some use a soft search at this stage, which does not affect your score. Others carry out a hard search, which does leave a footprint. A broker can advise which approach a particular lender takes before you apply.
2. How many hard searches is too many?
There is no fixed number. However, several hard searches in a short period can lower your score and may concern lenders. Spacing out applications and targeting the right lender first time helps avoid this.
3. Can I check my credit report without affecting my score?
Yes. Checking your own report is recorded as a soft search and is not visible to lenders. It does not affect your credit score.
4. How long do hard searches stay on my credit file?
Hard searches typically remain visible on your file for one to two years, depending on the credit reference agency. Their impact on your credit score usually diminishes over time.
5. Do all lenders check the same credit reference agency?
No. Lenders choose which credit reference agency or agencies they use. Some check one, others check two or all three. A multi-agency credit report shows what each agency holds about you.
6. Can a broker check my credit without a hard search?
A broker may ask you to provide a copy of your own credit report or may request your permission to carry out a soft search. This allows the broker to assess your position without adding a hard footprint to your file.
7. What should I do if I have been declined after a credit check?
Avoid applying again immediately, as further hard searches could compound the issue. Instead, review your credit file to understand what may have caused the decline, address any issues and seek broker advice before reapplying.
