Mergers & Acquisitions




One of the most complex and largest Financial Services systems and data migrations in recent years delivered successfully without impact to customers or our client.

In 2017 Legal & General took a decision to divest a large part of their legacy savings business.

This divestment comprised 6 Million customer policies and £30 billion of assets. The IT environment supporting this client business was highly disparate with a legacy of 100s of applications, some dating back over 50 years.

Aveas were engaged to bring their experience of Mergers & Acquisitions to help prepare for sale and separation, and once the deal was successfully agreed act as IT Integration Partner for the separation and migration of the business.

Our willingness to challenge convention, divert our approach when alternatives were presented and to implement rigorous governance made this Programme so successful.

“This was the most complex migration we have undertaken and the Aveas team did an outstanding job leading the migration workstream through the entire process from initiation to Programme closure” – Feargal Supple, Programme Sponsor

“Thank you Aveas for all your exceptionally hard work and amazing effort” – Claire Singleton, CEO Mature Savings
