AI is changing how accountants and lawyers do their jobs in the UK, but it won’t take their place. By 2026, automation will handle routine tasks like bookkeeping and document review, yet human expertise in advisory, complex decision-making and client interaction remains irreplaceable. Instead of replacing people, the future will likely see professionals working alongside machines.
Current State of AI in UK Accounting and Legal Sectors
The UK’s professional services sector is a major pillar of the economy, employing roughly 350,000 accountants and about 200,000 practising solicitors as of early 2025. AI adoption has accelerated sharply in recent years, yet the technology is primarily seen as a way to augment human work rather than replace it outright. In accounting, software platforms like Xero, QuickBooks, and FreeAgent now embed AI features that automate routine tasks including bookkeeping, bank reconciliation, receipt scanning, and basic tax return processing. These tools use machine learning algorithms to reduce errors and speed up processes that once took hours.
On the legal side, AI-powered applications such as Harvey AI are increasingly common in larger firms. They assist with document review, contract analysis, due diligence, and legal research, enabling lawyers to sift through vast amounts of text quickly and focus on higher-level tasks. Some mid-sized firms are also experimenting with AI for case prediction and client intake automation, though uptake varies widely.
Even with these advances, humans still play a key role, especially where empathy, creativity, and judgement matter most. Complex tax planning, compliance advice, client relationship management, court advocacy, negotiation, and bespoke legal counsel continue to rely heavily on professional expertise.
A July 2025 survey by Accounting Today found that 72% of UK accountants are comfortable using AI tools for traditional tasks, and 53% report that AI already makes them more effective. However, only 36% say AI makes their jobs more enjoyable, reflecting ambivalence about how the technology changes their daily work.
Similarly, a 2024 report from the Law Society of England and Wales showed that while 67% of solicitors use AI tools for research or document review, 81% believe that AI can't replace the human skills required in client negotiations or courtroom strategy. These figures underline a cautious but pragmatic view of AI as a helpful partner rather than a threat.
Key Developments Driving Change
The Big Four accounting firms—Deloitte, PwC, EY, and KPMG—are at the forefront of AI investment in the UK. They collectively have poured over £500 million into AI-driven platforms and training programmes since 2022. Their approach focuses on using AI to boost capacity and efficiency rather than cut headcount.
For example, they deploy AI to automate routine data entry, bank reconciliations, and error checking, which frees senior accountants to concentrate on strategic advisory roles and client relationship building.
Legal firms in the Magic Circle, such as Clifford Chance and Allen & Overy (now known as A&O Shearman), lead AI adoption within the legal sector. Allen & Overy was the first UK firm to implement Harvey AI in 2023, harnessing it to accelerate document review and contract analysis during complex mergers and acquisitions. This cut due diligence times by up to 40%, according to internal reports. Clifford Chance has similarly integrated AI-powered tools for predictive analytics and risk assessment in litigation.
Still, these firms stress that AI is there to support, not replace, their work. AI can flag key clauses or inconsistencies, but it can't replace the nuanced judgement and advocacy skills required in court or intricate negotiations. Senior partners have repeatedly stated that AI frees up lawyers to focus on value-adding tasks rather than routine work.
On the policy front, the UK government unveiled the National AI Strategy in September 2021, committing £1 billion in funding to AI research and adoption across sectors, including professional services. The government’s Office for Artificial Intelligence collaborates with the LawTech Delivery Panel and the Institute of Chartered Accountants in England and Wales (ICAEW) to promote responsible AI use. New regulations introduced in 2024 require transparency about AI use in client services, ensuring ethical standards are maintained.
Meanwhile, the Financial Conduct Authority (FCA) published guidelines in early 2025 on AI risk management in financial and professional services, highlighting the need for human oversight and accountability. Professional bodies have increased training programmes on AI literacy, with ICAEW reporting over 15,000 members attended AI-related workshops between 2023 and 2025.
Industry Impacts and Changing Roles
AI is changing what jobs look like instead of cutting them out completely. In accounting, junior roles focused on data entry and manual reconciliations are declining. Instead, there’s a growing demand for accountants skilled in data analysis, AI oversight, and strategic advisory. According to a 2025 recruitment survey by Robert Walters, vacancies for accountants with AI proficiency increased by 35% year-on-year in the UK.
Law firms report similar trends. Paralegals spend less time on document review, which AI can perform faster, and more time on client communication and case strategy. The Law Society’s 2024 workforce report notes a 28% rise in demand for lawyers with technology skills, including AI management and cybersecurity awareness.
Some smaller firms and sole practitioners face challenges adopting AI due to costs and technical expertise gaps. However, cloud-based AI solutions with subscription pricing have lowered barriers. FreeAgent, for example, offers affordable AI features tailored for small accounting firms and freelancers, with prices starting at £15 per month.
Clients benefit too. Faster turnaround times, improved accuracy, and more insightful advice are driving demand for AI-enabled services.
Yet clients still value the personal touch and trust built through human relationships, which AI can't replicate.
Expert Views on AI’s Future in Professional Services
Experts broadly agree that AI will transform but not replace accountants and lawyers. Dr Sarah Mills, a technology policy analyst at the University of Edinburgh, says, "AI excels at automating repetitive tasks but struggles with context and ethics, which are vital in law and accounting." She adds that "future professionals will need a hybrid skill set—technical proficiency and emotional intelligence."
John Templeton, partner at PwC UK, notes, "Our investment in AI is about empowering our people, not cutting jobs. It’s about making our professionals more efficient and allowing them to focus on complex client problems." He predicts that by 2026, AI will handle up to 50% of routine accounting tasks but will only complement human judgement in legal practice.
Meanwhile, the Law Society’s chief executive, Christina Blacklaws, warns against overhyping AI. "AI is a tool, not a panacea. Regulation and ethical considerations must keep pace with technological advances to protect clients and maintain professional standards," she said in a 2025 interview.
What’s Next for AI in UK Accounting and Legal Fields?
Looking ahead to 2026 and beyond, AI adoption is set to deepen and diversify. Firms plan to expand AI use beyond routine tasks into areas like fraud detection, predictive analytics, and personalised client insights. The National AI Strategy aims to position the UK as a global leader in trustworthy AI, with a focus on transparency, ethics, and human-centred design.
Training and education will be crucial. Universities and professional bodies are updating curricula to include AI literacy and data ethics. The ICAEW aims to have 80% of its members trained in AI-related skills by the end of 2026.
However, challenges remain. Smaller firms must overcome cost and expertise barriers to compete. Ethical questions about AI bias, data privacy, and accountability will require ongoing attention. Regulators will continue to monitor AI’s impact to ensure public trust.
Still, one thing is clear: AI won’t make accountants or lawyers obsolete in the UK. Instead, it will change how they work—automating the mundane, sharpening the focus on human insight, and opening new possibilities for professional growth and client service.
AI isn't the end of accountants and lawyers in the UK. Instead, it’s a force reshaping their roles—automating the mundane while spotlighting the human skills that machines can’t replicate. By 2026, expect routine tasks to be mostly handled by AI, but the nuanced, complex, and deeply human aspects of these professions will remain firmly in human hands.
