Applying for any form of credit involves a hard search on your credit record that can impact your score. If your application is successful, any dip in your credit score will usually only be temporary and it should start to improve again as you make your monthly repayments on time.  Unsuccessful applications will have a bigger negative impact on your credit score, making it harder to get accepted for future deals. Try to space out applications so there is a six-month gap after any rejections. Before you apply for a remortgage, check your credit files with the three credit reference agencies (Experian, Equifax and TransUnion) to make sure you’re in the best shape to get a deal.
