Case Study: OakNorth Bank achieves consolidated AML screening and reduced false positives with ComplyAdvantage

OakNorth Bank - Customer Case Study

OakNorth Bank, a UK commercial lender and savings provider, faced fragmented screening processes across its lending and deposit operations that produced time‑consuming PEP/sanctions checks and high false positive rates. To consolidate workflows, integrate with its tech stack, and keep lending and deposits' case management separate, OakNorth selected ComplyAdvantage’s AML Customer Screening and Ongoing Monitoring as an API‑driven solution.

ComplyAdvantage delivered a single platform with comprehensive data, a two‑way RESTful API, configurable search algorithms and tailored case‑management workflows; its team worked with OakNorth to tune PEP and sanctions screening (including fuzziness and enrichment testing). The result: new applicants now show a 2.3% hit rate and the migrated overall portfolio a 4.1% hit rate, significantly reducing false positives, speeding escalation and audits, and enabling the compliance team to focus on higher‑value work.
