Lending and Security Guidelines

Our lending and security guidelines must be read in conjunction with the COVID-19 support page which outlines any temporary lending policy changes. If there is a conflict, the information on the COVID-19 support page will apply.

This page provides guidance for mortgage intermediaries on the areas the West Brom will consider as part of its mortgage underwriting processes.

In addition to the guidelines set out in this page, the West Brom also applies a number of proprietary credit assessment tools, the outcome of which may result in a case being declined despite appearing to fit within the guidelines set out in this page.

The West Brom retains the right to change its underwriting policy at any time and without necessarily updating these guidelines. However, the West Brom will endeavour to ensure the guidelines set out in this page represent the Society’s current approach to lending.

In the event of any clarification being required please contact the Intermediary Sales and Support Team (ISST) or your Business Relationship Manager (BRM). Prior to submission of supporting documentation please contact the BRM for clarification of any items or policy which may require further investigation to ensure cases are processed in a timely manner.
