TLDR: A recent LexisNexis study reveals a significant increase in generative AI adoption among UK lawyers, with 61% now using these tools in their professional practice, up from 46% in January 2025. While AI is boosting productivity, billable hours, and work-life balance, two-thirds of legal professionals warn that slow organizational cultures are hindering full integration. The report, titled ‘The AI Culture Clash,’ highlights a growing divide between rapid adoption and strategic embedding of AI within firms, posing potential talent retention risks for those lagging in investment.
London, UK – September 3, 2025 – The legal landscape in the United Kingdom is undergoing a rapid transformation, with a new study from LexisNexis Legal & Professional revealing a substantial surge in the adoption of generative artificial intelligence (AI) tools among lawyers. The report indicates that 61% of UK lawyers are now leveraging generative AI in their daily work, a sharp increase from 46% recorded in a similar study conducted in January 2025.
The comprehensive survey, which gathered responses from over 700 UK lawyers in August, underscores the growing integration of AI into legal practice. Furthermore, the proportion of legal professionals with no plans to adopt AI has significantly dropped from 15% to just 6% over the same period, signaling a widespread acceptance and recognition of AI’s potential.
While adoption rates are soaring, the study, aptly titled ‘The AI Culture Clash,’ also highlights a critical challenge: organizational culture. Two-thirds of respondents expressed concerns that slow or outdated organizational cultures risk stalling AI-driven progress. Only 17% of legal professionals believe AI is fully embedded into their firm’s strategy and operations, with a majority reporting that their firm’s AI culture remains either slow-moving or non-existent.
Stuart Greenhill, senior director of segment management at LexisNexis U.K., emphasized the tangible benefits lawyers are experiencing. ‘They’re using it to increase billable hours, rethink pricing models and deliver more value to clients,’ Greenhill stated. He added, ‘Firms that treat AI as a strategic investment, not just an efficiency tool, will gain a decisive edge in profitability and client satisfaction.’
Lawyers are utilizing AI for a variety of tasks, with just over half (51%) opting for tools specifically designed for legal work, such as Lexis+ AI. Among these, 27% use legal AI tools exclusively, while 24% combine them with general AI tools. Confidence in AI output is notably higher when grounded in trusted legal sources, with 88% of exclusive legal AI users reporting greater assurance.
The impact on productivity and well-being is also evident. Over half (56%) of private practice lawyers reported using the time saved by AI to increase billable work, while 53% leveraged the extra time for a better work-life balance. Priorities vary by firm size and role; larger firms tend to focus on commercial gains, whereas smaller firms place a higher value on well-being. Associates across all firm sizes are prioritizing increased billable hours.
AI is also poised to reshape billing models, with almost half (47%) of lawyers agreeing that AI will transform how firms bill for legal services, an increase from 40% earlier this year. Law firm leaders (55%) and general counsel (49%) are particularly attuned to this impending shift.
The report also flags a significant talent retention risk for firms that fail to adequately invest in AI. Nearly one in five (18%) private practice lawyers and in-house counsel (19%) would consider leaving their organization if it lagged in AI investment, a figure that rises to 26% among those at large law firms.
Beyond generative AI, broader AI integration is also on the rise. A separate report from Clio in July 2025 indicated that 96% of UK law firms integrate AI into their operations, with 62% of solicitors planning to expand AI use in the coming year. Key applications include document drafting and automation (36%), contract review and analysis (29%), and legal research (17%). The Solicitors Regulation Authority even authorized Garfield.Law in May 2025, the first fully AI-driven firm in England & Wales, highlighting the regulatory landscape’s adaptation to this technological evolution.
