Mortgage Credit Directive and Buy to Let mortgages

The Mortgage Credit Directive (MCD), effective 21 March 2016, introduces a legislative framework for Consumer Buy to Let (CBTL). This covers the small number of Buy to Lets where the borrower has not entered into the mortgage contract for business/investment purposes.

Buy to Let mortgages for business/investment purposes are not covered by the new MCD rules. This type of mortgage will be known as Investment Buy to Let.

Our approach

  • We’ll offer both Investment BTL and CBTL mortgages.
  • We’ll continue to use the same lending policy, rental coverage calculation and products for both.
