Solomonic launches the UK’s first data-driven recognition of Commercial Litigation excellence
Using six years of court data, providing a clear, evidence-based view, based on activity in the Commercial Court, Business and Financial List.
There has always been an appetite, particularly among in-house teams, for credible data on heavyweight legal expertise.
Traditionally, the market has relied on a mixture of anecdote, reputation and relationships.
That gap is what Solomonic’s new Powerhouse methodology is designed to address.
Solomonic CEO, Edward Bird, commented: “Solomonic’s belief is that data brings considerable value to litigation decision making. This is the first time heavyweight litigation capability has been validated with data.
The law firms in this list stand out not simply because they have, over a six year period, consistently been instructed to act in a high volume of high-stakes disputes, but because they have achieved strong results for their clients, and shown a mastery of the process, including running complex cases all the way through to trial.”
The methodology
Our model is designed to move beyond a narrow, single-year or single-metric view of litigation performance. Instead, it evaluates law firm activity across multiple, weighted dimensions over a sustained period (2020–2025), capturing not just volume, but quality, complexity and consistency.
The algorithm incorporates:
Claim volume and scope, reflecting range of activity on both claimant and defendant sides
Claim value, capturing exposure to high-stakes litigation
Success rates, measuring outcomes rather than just participation
Days in court, indicating experience in running matters through contested hearings and trial
Year-on-year consistency, rewarding firms that perform strongly across multiple cycles, not just once
Each factor is weighted separately, allowing the model to balance scale, quality, experience and durability.
All of these firms have maintained volume and standards through market cycles, economic shocks and changing litigation trends. The data identifies these firms as established and trusted powerhouses, and we congratulate them on their inclusion in this year’s list.
Firms listed in alphabetical order.
From an in-house perspective, this answers a fundamental strategic question: when you need proven litigation expertise, who does the market turn to time and again?
“We believe this empirical view of law firm capability will, in time, inform panel selection. Our methodology considers a wide range of performance criteria and places particular weight on consistency, ensuring that recognition reflects sustained performance in terms of activity, impact and outcomes,“ added Solomonic’s CRO, Peter Nussey.
This ranking does not replace qualitative judgment or sector-specific expertise. Instead, it provides something the legal market has lacked until now – a rigorous, transparent, data-supported benchmark for sustained litigation excellence.
