Applying for a remortgage involves a credit search, which may cause a small temporary dip in your credit score. This is normal and usually short-lived. The impact is generally minimal compared to the benefit of securing a suitable mortgage deal.
Maintaining consistent, on-time payments on your mortgage and other financial commitments has a stronger long-term effect on your credit profile. Multiple applications within a short period can have a greater impact, so careful planning is advisable.
Switching lender itself does not damage your credit history, provided repayments remain up to date. A stable credit record supports access to more competitive mortgage products in future.
