No. When you request a RateEstimate, Plenti Pty Limited Limited will request a copy of your credit file as an 'access seeker', known as a soft credit check. A soft credit check is only visible to you and other access seekers, will not be visible to other credit providers and does not impact your credit score.
If you complete a loan application Plenti RE Limited will submit a credit enquiry and request your credit file. This may impact your credit score.
