Every credit application in the UK triggers a credit check. The type matters enormously: soft checks leave no visible trace, while hard searches create a footprint that other lenders can see. Multiple hard searches in a short period can signal desperation and hurt your chances of mortgage approval.
What Is a Soft Credit Check?
A soft check gives a lender enough information to assess your eligibility without leaving a mark. You'll see it on your own file but other lenders won't. Soft checks occur when: you check your own credit file, companies do identity verification, or you use an eligibility checker before applying.
- •Checking your own credit file: always soft
- •Eligibility checkers (MoneySavingExpert, comparison sites): soft
- •Pre-approved offers: soft
- •Employer identity checks: soft
- •Utility company identity verification: usually soft
What Is a Hard Credit Check?
Hard searches occur when you formally apply for credit — a credit card, loan, mortgage, phone contract, or car finance. The lender runs a full check, which leaves a footprint on your file visible to all other lenders for 12 months. Multiple hard searches in a short period look like you're desperately seeking credit and can lower your score.
- •Credit card application: hard search
- •Loan application: hard search
- •Mortgage application: hard search (often multiple from different lenders)
- •Mobile phone contract: often hard search
- •Utility account setup: usually soft, but can be hard
How long do hard searches stay on my file?+
Hard search footprints are visible on your credit file for 12 months, though they count less over time. They typically fall off completely after 12-24 months depending on the agency.
How to Avoid Unnecessary Hard Searches
Before formally applying for any credit product, use a soft eligibility checker to assess your chances. Most major lenders and comparison sites offer these. If the eligibility checker says you're likely to be approved, apply. If not, look for alternative products — don't apply speculatively across multiple lenders.
- •Always use eligibility checkers before formal applications
- •Apply to one lender at a time — space applications out
- •Rate shopping for mortgages: multiple searches within 14-45 days may be treated as one
- •Check your credit file for unexpected hard searches — these could indicate fraud
- •Space applications by at least 3 months where possible
Does Rate Shopping Hurt Your Score?
Credit reference agencies understand that borrowers shop around, particularly for mortgages. Experian, for example, uses a "rate shopping" window where multiple mortgage searches within a short period are treated as a single enquiry. However, the window and treatment varies by agency and lender. To be safe, use a mortgage broker who can submit to multiple lenders with a single application.
- •Experian: multiple mortgage searches within 14 days = one enquiry
- •Use a mortgage broker to minimise hard searches
- •Car finance: multiple dealer searches in a day can still leave multiple marks
- •Personal loans: avoid applying to 3+ lenders at once
- •ALWAYS use eligibility checkers first
