Monmouthshire goes live with Phoebus as part of major Society transformation programme

27 April 2026

Monmouthshire Building Society has gone live with the Phoebus solution to provide mortgage account servicing to its borrowers.

Following a Discovery Phase, the implementation commenced in Q4 2025 and provides integration with MQube to seamlessly onboard completions utilising the Phoebus originations API. This initial phase will see Monmouthshire’s full range of mortgages onboarded including residential, development, buy-to-let and holiday-let products.

The Society has access to the full suite of Phoebus APIs as part of the solution. Phoebus will provide Monmouthshire with significant return on investment by providing operational savings through substantial account automation across its whole mortgage operations. This covers all areas of servicing ranging from basic tasks through to more advanced requirements including arrears management and special servicing. In future phases this will also include Monmouthshire’s savings operations.

The next phase of the transformation programme will be to migrate all existing mortgage and savings accounts onto the Phoebus solution using the same API technology.

Adam Oldfield, chief executive officer at Phoebus says,

“From the initial tender process, Monmouthshire has been a fantastic client to partner with, and both organisations have worked efficiently to get the solution live to plan and budget. The multi-million pound investment we have made in our mortgage and savings product, including the ability to migrate books of any size accurately and efficiently, means we are a great fit for any Society considering moving to modern SaaS technology, backed up by proven, referenceable experience.”

Dawn Gunter, chief operating officer, at Monmouthshire Building Society says,

“It is fantastic to work with a core provider that delivers to plan and brings the capability and expertise to support the Society on its digital journey, enabling greater automation and more efficient day-to-day operations. We look forward to a great partnership with Phoebus for many years to come.”
