Being a one stop shop for a leading high street bank



4most have a long-standing relationship working with a well-known, leading UK retail lender that provides high street and internet banking, current accounts, mortgages, savings accounts, credit cards and loans.
In recent years, the Bank has been undergoing complex challenges as it modernises and transitions under stringent regulatory changes. This required a multi-faceted, strategic approach which involved strengthening their validation function, full model redevelopment alongside advising on internal governance framework.

We delivered multiple services across several functions, which can be split into the following core areas:

“I believe our long-term partnership with the Bank has helped them to secure their position as a leading UK retail lender.”
- Damien, Partner

    • Creation of a model monitoring suite.
