Former EY and PwC execs launch firm to challenge Big Four in UK

Unity Advisory, a new UK-based firm launched by former EY and PwC executives, is aiming to disrupt the dominance of the Big Four.

Backed by private equity firm Warburg Pincus, Unity targets mid-sized businesses (£500m–£1.5bn turnover), offering tax, accounting and M&A services—excluding audit to avoid regulatory conflicts.

Led by Steve Varley and Marissa Thomas, the firm promises a more agile, AI-powered alternative to the larger players, with innovative pricing and a client-first approach.

Amid scandals and client dissatisfaction affecting the Big Four, Unity’s launch reflects a broader industry shift towards tech-driven, private equity-backed models in professional services.

Is agentic AI the future of tax and accounting efficiency?

Agentic AI is emerging as a transformative force in tax and accounting, moving beyond automation to act autonomously—managing complex, multi-step processes like tax filings and audits with minimal human input.

Unlike traditional AI, it can reason, decide, and execute in real time, freeing accountants to focus on strategic planning and client advisory. While its potential is significant, the technology raises pressing concerns around data governance, regulatory compliance, and professional oversight.

Firms must rethink their workflows, invest in new skills, and build trust in AI systems. This shift from AI as a tool to a collaborative partner could redefine professional value.
