The firm promoted 24 new partners in its consulting service, with 20 in financial advisory, 18 in audit and risk advisory, 17 in tax and one in internal client services.
In a bid to strength its regional network, 24 of the new partners are based outside London.
Deloitte said it continues to focus on gender diversity, with 30% of the new partners being women.
David Sproul, senior partner and chief executive of Deloitte UK, said the promotions represent “another positive year for partner promotions, reflecting the continued success of the firm despite uncertain economic conditions”.
“Achieving greater gender diversity is a clear business imperative and these promotions evidence the success of the range of initiatives we have put in place.”
Sproul won an award from the United Nations in March in recognition of his commitment to advancing women in the workplace.
Deloitte introduced the Return to Work programme last year, which helped the firm to attract more senior female leaders back to the workforce.
Five new partners are working part-time, as part of Deloitte's WorkAgility framework.
Emma Codd, managing partner for talent, said, “Deloitte is committed to ensuring that it has a culture and environment in which our people are able to balance a successful career with commitments outside work - whether that is family, other caring commitments or other interests.
“We know that our people expect to work for an employer that can offer a balance between career and life and we have worked hard to provide this to all our people including our senior leaders.”
