Buy to Let Mortgage Information

We offer a range of Green mortgages to help support your clients with more energy efficient Buy to Let properties. We have better rates available for purchase and remortgage properties with energy performance ratings A-C.

Green Buy to Let mortgages

We offer a range of Green mortgages to help support your clients with more energy efficient Buy to Let properties. We offer better rates for properties with energy performance ratings A, B or C, available for both purchase and remortgage.

It’s as easy to secure one of our Green products as a standard Buy to Let - you don’t need to provide anything extra. Simply make sure the property has a valid energy performance certificate (EPC) showing a rating of A, B or C to qualify. This can be checked here, or here for Scottish properties.

Green mortgages are available for both ICR and Top Slicing.

Standard Buy to Let mortgages

If your client’s property has an EPC rating of D-E, we have a range of standard Buy to Let mortgages to choose from.

Your client’s affordability

There are 2 ways to calculate your client’s affordability for any of our Buy to Let mortgages:

  • ICR – this uses your client’s rental income to calculate affordability.
  • Top Slicing – this boosts the amount the client can borrow by using a combination of rental income and their personal income.

ICR and Top Slicing mortgages are available in both our standard Buy to Let and Green ranges.

Use our Buy to Let affordability calculator to see how much they could borrow.

You can create an AIP with a soft footprint, only leaving a hard footprint once your client’s ready to proceed to a full application.
