FCA closes investigation into Mirabella Advisors, principal of Greensill Capital

The FCA has announced the closure of its investigation into Mirabella Advisors LLP. The FCA had launched an investigation into the firm in 2021 in relation to the oversight of Greensill Capital Securities Limited, the appointed representative of Mirabella.

The investigation considered the nature, conduct and scope of Mirabella’s business, but did not identify breaches that required further action. Mirabella applied to have its authorisation cancelled, and as of 12 September 2025, it no longer provides financial services.
