What is a hard credit search?

Hard credit search key figures at a glance

These are the figures worth knowing. Each comes from the organisation named, and all were checked in October 2026.

What is a hard credit search and when does one happen?

A hard credit search, also called a hard credit check or hard enquiry, is a lender’s full look at your report during a formal application.

You are asking to borrow money, and the lender wants the whole picture before it decides whether to lend.

Hard searches usually happen when you:

• apply for a mortgage, remortgage, loan or credit card
• apply for an overdraft or car finance
• take out a pay-monthly mobile phone contract
• apply to a utility supplier

You normally agree to the search when you accept the lender’s application terms. Equifax says a hard search cannot be made without your consent, and that the lender’s credit agreement often covers it. If you are unsure whether a company will run a hard or a soft search, ask before you apply.

Checking your own report is different.

A check of your own credit report is a soft search, and it does not affect your score however often you do it.

What does a hard search show a lender?

A hard search gives the lender your full credit report, which usually includes:

• your name, date of birth and current and previous addresses
• whether you are on the electoral roll
• your credit cards, loans and other borrowing, with your repayment history
• current account and overdraft details
• anyone you are financially linked to, such as a joint account or mortgage holder
• public records such as court judgments, bankruptcies and individual voluntary arrangements (IVAs)

TransUnion says active accounts can show up to 6 years of payment history, and defaulted accounts stay for 6 years from the default date. That means an old missed payment you have forgotten can still come up in a hard search.

It is one reason to read your own credit report before you apply.

What is the difference between a hard and a soft credit search?

The main difference is who can see the search and what triggers it.

A soft search is a lighter look at your file that other lenders cannot see, so it does not affect your score. A hard search is part of a formal application, and any lender that checks your report can see it.

Our guide to the soft credit search covers the other side in more detail.

Does a hard credit search affect your credit score?

Yes, but usually only slightly and only for a limited time.

One hard search tends to have a small effect, while several close together can lower your score. Lenders may read a run of searches as a sign that you rely on borrowing or are struggling to manage your money.

Experian says too many hard checks over a short period can affect your score for 6 months.

That is why a declined mortgage followed by several fresh applications can make things worse.

A lender that sees too many recent searches may respond in a few ways:

• decline the application
• offer less favourable terms, such as a higher interest rate
• offer a lower credit limit on a card or loan

Your wider record matters more than a single search, so payment history and the share of your available credit you use usually count for more. Spacing out applications is still sensible, because it keeps the number of searches down while you fix anything else that holds your score back.

Our guide to boosting your credit score explains how.

How long does a hard search stay on your credit report?

It depends on the credit agency, which is why your three reports can look different.

Experian says most hard searches stay on your report for 12 months, while TransUnion says they stay visible for around 2 years. The third agency holds its own file, so check your own report to see what it keeps.

Recent searches matter most to lenders, because several close together are the ones that suggest risk. A search made 18 months ago may still show on one report and have dropped off another, which is normal.

It also means you cannot assume a lender sees what you see, because you may not know in advance which agency a lender will check.

Can you remove a hard search from your credit file?

Not if it came from an application you made. The search is a true record of that application, and it stays until the agency’s retention period ends.

A search you do not recognise is different, because it can be a sign that someone has applied for credit in your name.

Ask the company that ran it why, and contact the agency whose report shows it. If an entry is wrong, the agency can investigate and correct it, adding a notice of dispute to your file in the meantime. You can also add a notice of correction to explain the circumstances behind a default, for example. This guide explains how to dispute an entry.

Do mortgage lenders use a hard credit search?

Decision in principle or full application?

Yes, at the application stage, although some use a soft search earlier on. A mortgage decision in principle is an early indication of how much a lender might lend, and some run only a soft search for it. Nationwide, for example, says a decision in principle uses a soft check and lasts 90 days (as at October 2026).

On a full application it runs a formal check that leaves a footprint on your report.

Why lenders run a search and how policies differ

Lenders search because they must check that you can afford the loan. FCA guidance (MCOB 11.6.13G) says a lender should confirm the credit commitments you give it, for example with a credit reference agency search.

Policies differ between lenders, so check which search a lender runs before you apply, or ask a broker.

What happens when you apply to several lenders?

For example, say you apply for a £500,000 mortgage and the lender declines you.

If you then apply to two more lenders within a fortnight, each full application can leave its own hard search. The third lender can see the earlier searches.

An independent mortgage broker can often tell you before you apply which search a lender runs. A broker can also judge whether your credit file suits each lender’s criteria, and that saves applications that are unlikely to succeed.

If a lender does decline you, find out why before you apply elsewhere.

Lenders treat past credit problems differently, so one decline does not mean every lender will say no. A string of declined applications can look worrying, though.

Our guide on what to do if your mortgage is declined walks through the next steps.

How can you limit the effect of hard searches?

These steps keep the number of hard searches on your file down:

1. Check your reports first. Look for errors and for searches you do not recognise before you apply, because fixing a problem afterwards can mean another application.
2. Use eligibility checkers. Some lenders and comparison sites offer checkers that use a soft search, which shows your likely chances without a hard search.
3. Ask for a decision in principle for a mortgage. Check first that the lender uses a soft search for it.
4. Space out your applications. A common rule of thumb is no more than 2 or 3 applications every few months, although lenders set their own criteria.
5. Apply only where you are likely to be accepted. An eligibility result, or a broker who knows lenders’ criteria, helps you choose.

How do you check the searches on your credit reports?

Where to get your reports

Each of the three credit reference agencies holds its own file on you, so it is worth checking all three. Equifax says you are entitled to a free statutory credit report for life, which you can request online or by post. The right is a legal one, and you can ask each agency for its own.

You can also use a service that shows all three reports in one place.

How many people check, and what they find

The FCA’s Financial Lives 2024 survey found that 34% of UK adults checked their credit report or score in the 12 months to May 2024. In that period, 10% of those who checked identified an error or issue, and 47% of them successfully corrected it, according to the same survey (a small sample, so treat that figure with caution). Only 5% of those who obtained a report or checked their score paid a fee to do so.

What to look for on your report

Each hard search on your report should match an application you remember making. Any that do not are worth querying. If you have borrowed little, you may have a thin credit file, which gives lenders less to go on.

Next steps

Hard searches are a normal part of borrowing, and one rarely causes harm.

Problems usually start when several land close together or an application is declined. Before you apply for a mortgage, check your reports, correct any errors and find out which search each lender runs.
