Why choose first direct for your mortgage?

The perfect mortgage looks different to everyone, that's why we offer different rate types. Whichever first direct mortgage you choose, we could help you feel right at home:

  • Get an agreement in principle (AiP) that is valid for six months
  • Award winning team available seven days a week
  • lower monthly payments with terms up to 40 years and flexibility to change this at any time*
  • You could pay off your mortgage sooner with unlimited overpayments**

* This could mean that you will pay more interest over the lifetime of the mortgage.

** An overpayment may be subject to an Early Repayment Charge if the mortgage account is repaid in full during the fixed rate period.
