Soft versus hard searches
Every credit enquiry falls into one of two categories, and the difference matters enormously. A soft search is a quiet look at your credit file used to see whether you might be a fit for a product and to give an indicative quote. It is visible only to you when you view your own file, it is invisible to other funders, and it has no effect on your score no matter how many times it happens.
A hard search, sometimes called a hard credit check, is the opposite. It is recorded on your file where other funders can see it, it stays there for a set period, and it can nudge your score slightly, especially if several land in a short window. A hard search is what a funder runs when you formally apply and they are ready to make a real decision on terms.
The single most useful thing to remember is that soft searches are for exploring and hard searches are for committing. You control which one happens by choosing whether to browse offers or to proceed with a specific funder.
