The Big Four and Their Growing Influence in Legal Services

Competition for Talent

Aspiring solicitors already face intense competition for training contracts. Now, traditional firms must also compete with the Big Four, who are investing heavily in human capital. PwC recently increased newly qualified salaries to roughly £90,000, matching many silver circle firms. This followed its announcement that it intends to double the size of its legal division within 3 to 4 years. KPMG made similar claims, aiming to achieve comparable growth by 2022.

Lateral hiring is another key strategy. Big Four firms have long faced criticism for lacking legal prestige, with legal services perceived as secondary to consultancy and accountancy. To counter this, they have recruited experienced lawyers from established firms. Prestige cannot be manufactured, but it can be acquired through the reputations of those hired.

Financial strength plays a major role. In 2020, Kirkland and Ellis generated approximately $5 billion in revenue, while Clifford Chance generated $2.3 billion. These are substantial figures, yet Deloitte’s revenue exceeded $43 billion. This scale allows the Big Four to invest heavily in individuals whose reputations can elevate their legal practices.

Their size also offers additional advantages. Opportunities for international work and career transitions are more accessible. Competition for clients is less intense because the Big Four can draw on existing consultancy and accountancy relationships. These factors make the Big Four attractive destinations for lawyers seeking new challenges.

Competition for Clients

Big Four legal departments often serve existing clients, expanding their reach across service lines. Potential clients may also choose them because they offer integrated solutions across tech, consultancy and legal work. In a world where technical, financial and legal issues frequently intersect, this “end‑to‑end service” model is appealing.

Legal technology is another battleground. Once considered slow to evolve, legal tech has become central to performance strategies. Thomson Reuters reported in its Business Leaders Report that investment in legal tech is now the top priority for improving efficiency. Gartner predicted in 2021 that investment from in‑house legal departments will more than triple by 2025. Legal tech companies have grown rapidly, with some reaching valuations above $1 billion and several completing IPOs.

This surge in innovation has transformed the competitive landscape. Legal tech allows firms to cut costs and improve client experience. However, the playing field is uneven. The Big Four have vast financial resources and established connections with the tech sector, including their own legal tech incubators. This gives them a significant advantage as firms race to modernise their operations.

Conclusion

In the short to medium term, top law firms are unlikely to be displaced by the Big Four. Clients still value deep expertise and specialisation. EY’s recent structural changes have also created uncertainty around the future of its legal division. However, the integration of tech and legal services is accelerating, and the Big Four are well positioned to benefit.

While elite firms will continue to rely on their reputations, small and mid‑level firms may face greater pressure. The Big Four’s growing presence in the legal sector is no longer a distant threat. It is an active force reshaping the market.
