No, if you access your own credit report it will have no effect on your credit score.
Reviewing a credit report results in a 'quotation' or 'personal' search (soft search) meaning it will only be seen by you on your personal credit report.
However, when you apply for credit, the lender will review your credit report, and a 'credit application' (hard) search will be added. Credit application searches are shown to other lenders because they may represent new debt that doesn't yet show on a credit report as an account. Credit application searches can affect credit scores. You should check your report regularly to help identify any signs of fraud and to make sure you are managing your credit well.
