In March 2020, White took on an unpaid role to advise on the set up of a UK-wide network of testing centres as part of the UK Government’s response to the COVID-19 pandemic.

In September 2017, White succeeded Adrian Ringrose as CEO of Interserve. The company was “battling for survival” after warning it would breach bank loan covenants, and in early 2018 attempted to financially restructure its business. In November 2018, White said the group would unveil further plans to tackle its debt mountain in early 2019, later confirming a deleveraging plan that would result in “material dilution” for current Interserve shareholders. While the deal was agreed with lenders, it was subject to approval by Interserve’s shareholders, and Interserve risked going into administration if that approval was not given. At an AGM on 15 March 2019, the deleveraging plan was rejected by shareholders, its shares were suspended, and Interserve’s board applied for the parent company to be placed into administration while it pursued a pre-pack option. A new private company, Interserve Group Ltd, controlled by Interserve’s existing lenders, emerged. In November 2019, Interserve announced an operational restructuring of the business; as a result, White left the business at the end of 2019.

White trained as an accountant with Arthur Andersen, and later joined AstraZeneca and then PwC Consulting. In 2004, White was appointed as the chief financial officer of Sodexo’s UK operations, and rose to become chief executive of government and healthcare worldwide.
