A new challenger is stepping into the UK’s accounting and consulting arena (and it’s not a startup). Unity Advisory was co-founded by two former heavyweights from EY and PwC, aiming straight at the Big Four’s client base—armed with private equity firepower and a pitch for a lighter and conflict-free model. The details were released by the Financial Times this week.
Steve Varley, who led EY’s UK arm for nearly a decade, and Marissa Thomas, once PwC’s chief operating officer, are leading the charge. Backed by up to $300 million from Warburg Pincus, the boutique firm is expected to launch by June. Varley will chair Unity, while Thomas takes the reins as CEO. Their message is clear: Unity is here to offer CFOs a more efficient (and accessible) alternative.
Unity’s strategy hinges on what it won’t do: no audit services. That alone removes layers of regulatory complexity and potential conflicts of interest that the Big Four have long struggled with. Without those entanglements, the new firm is free to focus on advisory work (from tax and tech consulting to M&A guidance). The firm also aims to break with the traditional partnership model that dominates the sector.
Private equity, once a rare sight in professional services, is advancing the territory. Last year, Grant Thornton UK sold a majority stake to Cinven, and Warburg Pincus previously backed another services firm in the insurance sector. For Unity, the injection of long-term capital means freedom to build without the constraints of short-term partner returns.
Upper hand
Thomas, who left PwC after being passed over for the top job, is betting that experience (both hers and others’) will give Unity an edge. She plans to hire talent with Big Four backgrounds, especially those who’ve transitioned into industry roles. The target clients are mid-sized UK companies, particularly those with private equity investors and revenues between £500 million and £1.5 billion.
Fee structures are also up for disruption. Without audit work, Unity says it can offer different models, such as performance-based pricing or even “value sharing” for helping clients find operational savings. That flexibility could resonate with CFOs tired of the rigid charging for hours mindset.
For now, Unity is keeping a low profile as it builds its team and prepares for a mid-year launch. But with seasoned leadership, deep-pocketed backers, and a clear ambition to disrupt the norm, it’s setting the stage for a serious shake-up in the UK’s professional services landscape.
