What is a core banking system and why does Nottingham need a new one?

A core banking system processes all customer transactions, deposits, and account management. Nottingham's old system ran on outdated mainframe technology that was slow, expensive, and inflexible. The new SBS platform is cloud-native, allowing faster product launches and lower costs.

Will Nottingham Building Society's new core system make them faster than Revolut or Wise?

Not automatically. Infrastructure is necessary but not sufficient. Speed depends on organisational structure, decision-making, and culture. A better core helps, but Nottingham still operates as a traditional mutual—and that comes with compliance layers and governance that fintechs don't have.

Should I move my savings to Nottingham after this upgrade?

A new core system doesn't directly affect your experience as a saver. What matters: Are interest rates competitive? Is the mobile app smooth? These depend on what Nottingham *does* with the new platform, not just installing it. Watch their product announcements over the next 12 months.
