Former Battersea Power Station CEO Files Whistleblower Lawsuit Against Malaysian Owners
The former chief executive of Battersea Power Station has initiated legal proceedings against the owners of the iconic London landmark following his dismissal in May 2025. Don O’Sullivan, who previously worked at Galliard Homes, assumed the leadership role at the Malaysian-owned Battersea Power Station Development Company in June 2024 to oversee the next phase of the massive redevelopment project.
Background of the £9 Billion Transformation
Over the past decade, Battersea Power Station has undergone a remarkable transformation from a disused and decommissioned site into a sprawling 42-acre estate. The £9 billion project now includes approximately 2,000 residential units and hosts around 60 companies, marking one of London's most significant urban regeneration efforts.
Allegations of Whistleblowing and Wrongful Dismissal
O’Sullivan contends that his dismissal resulted from raising whistleblowing concerns about serious financial misreporting within the company. According to his legal claim, he reported these concerns in November 2024, after which he was allegedly excluded from business operations.
The case details that O’Sullivan's concerns were discussed during a board meeting in London on December 16, 2024, involving both the development company and BPS Holdings. He claims that the very next day, two executives who were the subject of his disclosures excluded him from the company, leading to his suspension on December 24, 2024.
O’Sullivan was subsequently dismissed on charges of gross misconduct in May 2025, which he argues was a direct retaliation for his whistleblowing activities.
Legal Proceedings and High-Profile Support
The former CEO has filed his legal action at the London South Employment Tribunal against the development group and four senior Malaysian executives. He is being represented by John Hayes, founder of Constantine Law, and has received support from the GMB union.
John Hayes, managing partner at Constantine Law, commented on the significance of the case: "O’Sullivan's claim will possibly be one of London's highest profile and most valuable whistleblowing claims because it involves one of London's most respected developers taking on a case against an iconic London development, owned ultimately by the Malaysian state."
Hayes emphasized the broader implications: "The case raises very important questions about the integrity of financial reporting at Battersea. It is regrettable that the delays in the Employment Tribunal system have resulted in the case being listed for hearing in 2029, but it is important that the case is now in the public domain. It will be extremely hard fought."
Extended Timeline Due to Tribunal Delays
Due to significant delays within the Employment Tribunal system, the case has been scheduled for a final hearing in 2029, meaning the legal battle will extend over several years before reaching resolution.
Battersea Power Station is represented by Brown Rudnick Solicitors in this matter. When contacted for comment regarding the allegations, representatives of Battersea Power Station did not provide an immediate response.
The lawsuit brings to light critical issues surrounding corporate governance, financial transparency, and whistleblower protections within major development projects, particularly those involving international ownership structures.
