Key remortgaging considerations

Before you get started with remortgaging, you’ll want to brush up on associated costs, the best time to act, and more. Here are some key remortgaging considerations to help you along.

  • When to act: Start looking to remortgage 3-6 months before your current deal ends to lock in the best possible rate.
  • Why remortgage: You could remortgage to secure a better interest rate, release equity on your property, and more.
  • How it works: Your new lender will run a valuation and credit check, similar to a new mortgage application.
  • Costs involved: Potential remortgage costs and fees include admin, valuation, legal fees and early repayment charges (ERCs).
  • Alternatives: If you want to stick with your current lender, a ‘product transfer’ allows you to switch to a new deal with them.
