The Non-Billable Podcast

PwC’s latest law firm survey points to a growing divide in the UK legal market. The largest firms are pulling ahead, specialist players are finding profitable niches and parts of the mid-market are coming under increasing pressure.
Mark Anderson, who leads PwC’s professional business services sector, joins the podcast to explain why more law firm mergers are inevitable and how firms caught in the “squeezed middle” can respond.
We also discuss why widespread AI adoption has yet to translate into financial returns, how the technology could reshape pricing, whether external capital has a role in Big Law and why cyber risk is back at the top of the agenda.

King & Spalding is in growth mode in London. The office increased revenue by 48% last year, has expanded its footprint at 8 Bishopsgate and recently hired a major international arbitration and litigation team from WilmerHale.
London managing partner Tom Sprange explains why the office has become central to the US firm’s international strategy. It is now King & Spalding’s fourth-largest office, its biggest outside the US and a hub connecting the firm’s practices across Europe, the Middle East and Asia.
The ambition is not to become a conventional full-service firm. Sprange describes a more selective model built around elite disputes, finance, private capital, investigations and regulatory work. He also explains why collaboration matters more than individual books of business, and why King & Spalding looks for practice builders rather than lawyers who simply claim to bring clients with them.
The conversation also explores the changing economics of international arbitration, the rise of the highly paid superstar partner and how firms can stop their best lawyers being poached. Sprange closes by setting out where King & Spalding could expand next and why the firm’s trainee pipeline remains important to its London plans.

Walker Morris has nearly doubled in size over the past seven years while holding on to a model that looks increasingly distinctive: one office in Leeds and no international network of its own. Revenue reached a record £90.2m last year, leaving the firm within reach of its £100m Ambition 27 target.
Managing partner Jeanette Burgess explains why she believes the single-site model still works. The bigger question is what happens beyond £100m. Burgess says Walker Morris can continue scaling from Leeds for now, although the firm is reviewing its options as it develops its post-2027 strategy. She also discusses why the firm is attracting lawyers looking for greater autonomy than they may find at larger City and national firms.
In relation to AI, Burgess expects firms may need “fewer, better people” in some areas and anticipates a gradual move away from hourly rates for routine work. But she rejects private equity as an answer to the investment challenge, arguing that surrendering control would cut against Walker Morris’ partnership model.

Charles Russell Speechlys has expanded rapidly under managing partner Simon Ridpath, opening in Milan and Singapore before making a defining move into the US this year.
The strategy is built around the firm’s ambition to become the world’s leading adviser to private capital – following wealthy individuals, families and entrepreneurs as their lives and investments become increasingly mobile globally.
In this episode, Simon explains why the US had become an unavoidable gap in the firm’s network, what he learnt during two-and-a-half years studying the market and why CRS resisted the temptation to accelerate its launch simply by “opening a chequebook”.
We also go inside the 2014 merger that created Charles Russell Speechlys. Simon reflects on the unusual challenge of combining two genuinely equal firms, why he prefers to talk about behaviours rather than culture and why mergers pursued principally for scale should make law firm leaders nervous.
Finally, we explore one of the biggest questions facing the profession: how partnerships will fund international expansion, AI and the increasingly complicated business of running a law firm. Simon explains why private equity ownership remains difficult for Big Law, where external investment could work on a project basis and how technology may force firms to overhaul traditional pay and reward structures.

Christian Bartsch is the CEO of Bird & Bird, the international law firm built around technology, IP and regulation. He joined the firm in 2007, became CEO in 2022 and was recently re-elected for a second term.
In this episode, Bartsch explains how he followed a leader who had run the firm for 26 years and why he involved the wider partnership in shaping Bird & Bird’s first five-year strategy.
He discusses the firm’s target of reaching €1bn in revenue by 2029, its recent expansion into Tokyo, Riyadh and Lisbon, and why India remains a market he watches closely. He also addresses law firm consolidation, external capital and the circumstances in which Bird & Bird might consider a merger.
The conversation then turns to AI, why Bartsch believes generic firms are vulnerable, how the traditional law firm pyramid may change and why training partners matters just as much as giving associates new tools.
