Willows, who is an ICAEW member, has been working for the Big Four firm since 1988. She was previously head of energy for the company.
She replaces Paul Long, who is stepping down after five years working as the firm’s chief financial officer, and Mike McDonagh, who was the head of operations and is now returning to client work in the US office.
Willows started her career as an auditor and later moved into international M&A and management consulting. She has since specialised in energy, advising some of KPMG's largest oil and gas clients globally, and spent two years in Moscow.
The new chief financial officer starts on the role after taking 14 months of maternity leave. Willows said she aims to ensure the firm strikes the balance between today’s investments and the future, while delivering profitable growth.
“It is important that we continue to focus on investing in and maintaining our core business offerings in areas such as audit, where we are winning the largest share of tenders and are the largest auditor of listed UK businesses,” Willows added.
According to Adviser Rankings’ Q3 guide, KPMG has held on to its position as the preferred auditor for stock market clients in the third quarter with 406 contracts, followed by PwC with 369 clients.
