There are two different types of search – 'quotation' or 'personal' searches and 'credit application' searches.
A quotation or personal search (soft search) is used in background checks or when you check your own report. A quotation search will also be generated when you go on the 'Offers' page in order to display personalised offers for you. These may appear in your ClearScore account under the name of the providers who conducted the search, but will only be visible to you. Quotation searches do not have any impact on your credit score.
A credit application search (hard search) occurs when a lending company checks your report before making a decision on whether to accept your application. This shows up on your report and stays there for 12 months.
If you have a lot of credit application searches, a lender may automatically reject you as these applications make it look like you rely on credit to get by, and that you could struggle to pay the money back.
