Highlights
- UK legal market growth is polarising, with Regulatory and Labour & Employment surging while other practice areas soften.
- Corporate legal departments now outpace law firms in GenAI adoption, exposing a widening technology and accountability gap.
- Clients increasingly judge firms on outcomes and commercial acumen, pushing hourly rates aside as the primary value measure.
The UK legal market has rarely faced a more consequential moment. Growth is normalising, clients have become more commercially demanding, and, critically, corporate legal departments are now more technologically advanced than many of the firms they instruct.
The State of the UK Legal Market 2026 report is clear: the firms that thrive will not be those with the deepest technical bench, but those capable of becoming genuine strategic partners.

Growth is concentrating, not disappearing
Net spend anticipation (NSA), a forward-looking measure of buyer spending intentions, stands at +5 percentage points in 2026, a return to the stable pre-pandemic baseline. But the aggregate masks a sharp divergence across practice areas:
- Regulatory: +28 pts, the clear demand leader
- Labour & Employment: +14 pts
- Corporate Law: +4 pts
- Insurance: –8 pts | IP: –5 pts | Disputes: –5 pts
Finance sector clients are even more bullish, with Regulatory hitting +38 pts. Internationally, 82% of UK buyers have cross-border legal needs spanning an average of 30 countries, and 44% plan to increase international spend in the next 12 months, outpacing the US (40%) and the global average (38%).
For law firms, this polarisation demands real strategic choices about where to invest and where to pull back.
What GCs actually want, and how it’s changing
General counsel are managing three competing priorities simultaneously, all of which are intensifying:
- Technology & automation: 43% of GCs now cite this as their primary efficiency lever, up sharply from 25% last year. Cost control no longer dominates; transformation does.
- Protection: 32% of GCs prioritise risk management and compliance, up from 19% the previous year. Yet only 41% consider external counsel briefings a valuable source of risk information, a gap that represents a significant opportunity.
- Enablement: Supporting business growth has more than doubled its share of mentions, from 11% to 27%. GCs are under pressure to demonstrate strategic value to the board, and they want advisers who help them do it.
Adding to the strain: 69% of in-house legal teams cite staffing and resource constraints as their primary barrier to delivering value. These teams are stretched thin and actively seeking external partners who can step in as genuine extensions of the legal function.
The AI gap: clients are pulling ahead
The most urgent finding in the report is the technology divide between corporate legal departments and the law firms serving them:
| Corporate legal teams | Law firms | |
|---|---|---|
| Organisation-wide GenAI adoption | 53% | 35% |
| Excited or hopeful about GenAI | 67% | 52% |
Where law firms are deploying AI, the focus is on back-office tasks:
- Legal research: 80%
- Document review: 74%
- Document summarisation: 68%
These are largely invisible to clients. And the accountability gap makes it worse: only 18% of UK law firms measure the ROI of their AI tools.
The days of charging hundreds of pounds an hour for junior lawyers to do tasks that AI can do more quickly and effectively is coming to an end.
Firms must move from positioning AI as a capability to demonstrating it as a source of tangible client value.
The new measure of value: outcomes, not hours
How clients evaluate law firms has fundamentally shifted. When asked what matters most in assessing external advisers:
- 39% cite quality and effectiveness
- 28% cite cost and financial measures
- 17% cite efficiency and time savings
The preoccupation with hourly rates is giving way to a more fundamental question: can this firm help us reach the right outcome? Clients are increasingly judging advisers on their ability to deliver measurable business results. The fastest-growing drivers of firm favourability reflect this:
- 37% cite business acumen
- 15% cite commerciality
As the report puts it: “Expertise is table stakes; commercial judgement is the differentiator.”
CoCounsel Legal UK: The practical path to closing the gap
Understanding the gap is one thing. Closing it at scale, with the speed clients now demand, is another. That is what CoCounsel Legal was built to address.
CoCounsel Legal UK is the only solution that combines advanced AI with Practical Law UK guidance and Westlaw UK authority, bringing research, drafting and analysis together in a single platform, with results that are structured, cited and fully verifiable.
That turns AI value from an internal talking point into an externally legible part of every engagement. Four capabilities put that principle into practice:
- Document review, contract analysis and regulatory research are handled with precision, freeing senior lawyers for the strategic advisory work clients value.
- Deep Research uses an agentic, multi-step approach to navigate large volumes of case law and regulatory change, structured legal reasoning at scale, not search.
- CoCounsel Legal UK integrates directly with Microsoft 365, document management systems and HighQ, meeting lawyers where they already work rather than adding another platform to manage.
- The HighQ and CoCounsel UK integration extends those capabilities directly into client-facing workflows. This accelerates document review, enabling self-service Q&A and delivering a demonstrably more responsive service.
The inflection point is here
The firms that recognise this moment and act will emerge stronger. Those that do not risk being left behind by clients who have already moved on. The path forward requires commercial courage and technology that delivers visible client value.
CoCounsel Legal UK provides that foundation. The firms that close the gap will not only retain their most important relationships — they will define what premium legal advice means for the decade ahead.
