Lloyds Banking Group reduces mortgage income verification from days to seconds with Vertex AI ML platform

As the UK's largest digital bank, Lloyds Banking Group needed to transform its legacy systems to meet evolving customer expectations around financial services. The income verification step in mortgage applications took days, creating friction in the customer journey. The bank also needed a scalable ML platform that could support experimentation across a large team of data scientists.

Lloyds Banking Group migrated to Google Cloud Vertex AI in 2024, creating a managed ML platform for over 300 data scientists and AI developers. The platform supports rapid ML experimentation and deployment, with models developed for mortgage processing, customer insights, and business analytics. The managed cloud services eliminated infrastructure overhead and enabled teams to focus on building models.

The income verification step in mortgage applications was reduced from days to seconds using ML models. Unplanned ML platform downtime was cut to zero. Over 300 data scientists now use the platform, developing new models in a fraction of the time previously required. The bank also saved 27 tonnes of CO2 in operational emissions through cloud efficiency.

• Migrating ML workloads to a managed cloud platform eliminates unplanned downtime and unlocks experimentation at scale.
• Automating mortgage verification from days to seconds directly improves customer experience in a high-stakes financial decision.
• A platform serving 300+ data scientists creates a multiplier effect where each new model builds on shared infrastructure.
