Cheeseman (pictured) will work alongside Barb chief executive Justin Sampson and will lead the company’s financial strategy and operations.

In addition, Cheeseman will manage procurement alongside the chief operating officer and oversee all audit and internal control operations.

Cheeseman replaces Barb’s long-standing Finance Director, Nigel McLachlan, who is retiring.

Previously, Cheeseman worked at RSMB as director of finance and HR, where she managed the financial and human resources functions of the company.

Prior to RSMB, she worked at TNS Research International, where she held senior finance positions in the UK and group office, and also worked as audit manager at Arthur Andersen.

Sampson said: “It’s been a bit nerve-wracking knowing that one day Barb would have to find a replacement for Nigel. For 25 years, his commercial acumen and unflappable wisdom has allowed Barb to keep a firm, but gentle, hand on the many aspects of corporate governance needed to deliver the industry’s standard for understanding what people watch. He retires with the tremendous gratitude of Barb’s directors.

“I’m delighted Sara has agreed to join the team as we continue to adapt and evolve our industry’s audience-measurement services. She’s a great addition to our leadership team as we continue to navigate our way forward.”
