New Era. New Possibilities. Growth with Purpose. Grant Thornton UK 2025 financial report.
In 2025, Grant Thornton UK chose momentum over convention.
At a time when much of the professional services market stood still, the firm made a deliberate, defining decision: to build the business that its clients and its people need today and in the future. The result is a new chapter of growth, investment and ambition, powered by bold choices and long-term thinking.
The most significant of those choices was the firm’s partnership with Cinven. Becoming the largest UK professional services firm to take external investment marked the start of a fundamental transformation, reshaping how Grant Thornton grows, invests and competes.
Today Grant Thornton UK publishes its report with the combined financial statements of Grant Thornton UK LLP and Grant Thornton UK Advisory & Tax LLP and its subsidiary entities (together the “Proforma UK Group”) for the year ended 31 December 2025. The results show a business growing with confidence, resilience and purpose.
Against a backdrop of flat or declining revenues across much of the market, Grant Thornton delivered +4% revenue growth to £787m and an underlying operating profit growth of 30% to £189m.
Audit and Tax achieved robust growth year-on-year, offsetting softer demand in Advisory in line with wider market trends. The firm’s performance highlights the resilience of the business, which is underpinned by the strength of its continued investment in quality, talent and digital.
As set out following the Cinven investment, the redesigned partner model is intended to unlock market leading reward over time, balancing in year income with long-term value creation. For 2025, the average compensation per partner was £686,000 (£682K for prior year) reflecting a period of deliberate structural change and significant investment. The compensation per partner reflects these conscious choices to reinvest and grow rather than optimise short-term distributions, while building a larger, more resilient leadership base for the future.
A partnership for the future
Growth in 2025 was matched by growth in leadership.
Grant Thornton expanded its partnership at pace, appointing nearly 40 equity partners and 64 directors during the year. Ninety-one percent of director appointments came through internal promotion, and more than 1,900 colleagues progressed into new roles across all levels of the firm. This momentum continues in 2026, with plans underway to appoint a further 160 partners over the next two years. 31 equity partners have been recruited towards this total so far in 2026, 77% of which were internal promotions.
All Grant Thornton UK partners join on an equity basis unless they choose a salaried route. The firm’s new partner model breaks with tradition in the sector, offering a balance of in-year and long-term incentive rewards designed to recognise impact, leadership and sustainable growth. Typically, this unlocks partner reward with a 50% premium to market rate, which is then backed up by new, market-leading tailored onboarding and development programmes. It’s a dynamic, ambitious environment designed for leaders who want to make a real impact and share in the firm’s future growth.
Investing in foundations for growth
The firm’s investment in future skills also accelerated. Grant Thornton welcomed its first cohort of digital trainees and committed £1m to digital mindset learning for partners and trainees. These early foundations set the stage for a milestone moment in early 2026, with the announcement of a £500m investment in client experience, powered by digital innovation.
While technology is key to transformation, people remain the driving force behind Grant Thornton’s success. In 2025, the firm became the first major professional services firm to establish an Employee Benefit Trust, giving employees the opportunity to share directly in the value they help create. As part of this commitment, Grant Thornton awarded a £39m exceptional bonus to employees in recognition of their contribution to the firm’s financial performance, quality and culture, the largest investment in bonuses in our history.
Malcolm Gomersall, Chief Executive Officer of Grant Thornton UK, said:
“In 2025 we made bold, deliberate choices. Choices that ensure we are not simply responding to change but helping shape the future of professional services. At the centre of this is our investment in our people. From rapidly expanding our partnership to launching our Employee Benefit Trust, we’re building a firm where colleagues at every level share in the value they help create.
“But recognising contribution is only part of the story. The future demands new skills and new ways of working. That’s why we invested in digital mindset learning and hired our first cohort of digital trainees, bringing fresh capability to a rapidly evolving market. These foundations set the scene for our milestone £500m investment to transform the client experience through data, technology and digital tools. This is not just a technology upgrade; it is a fundamental shift in how we work, collaborate and deliver value.
“As we look ahead, our success will depend on sustaining a high-performance culture, one where our people are empowered, ambitious and equipped to meet the evolving expectations of our clients with clarity, confidence and excellence.”
