UK Midsize Law Firms Prioritise Technology but Risk Leaving Growth on the Table, New Report Warns

Actionstep, the leading law firm management platform for midsize firms, today released its 2026 UK Midsize Law Firm Priorities Report, offering a detailed analysis of the investment priorities, operational pressures, and competitive dynamics shaping the UK mid-market legal sector this year.

Conducted in partnership with specialist legal publication LPM, the research gathered insights from 52 law firm leaders, including managing partners, CEOs, COOs, finance directors, and heads of IT, risk, and people functions, across firms with between 20 and 300 employees.

The findings reveal a market in confident growth mode, with digital transformation (66%) and talent investment (70%) firmly at the top of the agenda. However, the report identifies a critical strategic blind spot: despite cross-selling and client retention being cited as a primary growth driver by 57% of respondents, only 30% say improving client satisfaction is a top priority for driving revenue growth.

Growth ambition is strong, but alignment is missing

UK midsize law firms enter 2026 with clear ambitions. Forty percent are targeting growth in markets where they already have a presence, 26% plan to increase rates, and 57% are evolving their pricing models. Yet the research suggests that the operational and client experience foundations required to sustain that growth are not fully in place.

Just 2% of firms describe their digital environment as fully “optimised,” and only 27% say their systems are genuinely integrated. Meanwhile, 45% report limited client feedback mechanisms, a figure that jumped 10% in a single year, and half identify inconsistencies across client touchpoints.

“Midsize firms have a genuine competitive advantage: closer relationships, clearer points of contact, and stronger continuity,” said Oliver Tromp, Regional VP, UK at Actionstep. “But relationship-led service alone is no longer sufficient to meet rising client expectations around speed, transparency, and accessibility. The firms outperforming their competition underpin their personal service strengths with connected, automated workflows, turning individual relationships into scalable, consistent service delivery.”

Automation is moving from convenience to competitive necessity

The report finds that automation is rapidly becoming essential to protecting profitability at scale. More than three-fifths (63%) of leaders are implementing or actively considering automation, with 58% citing the elimination of manual administrative work as their primary technology investment motivator. A further 38% say increased automation in business management is “essential” within the next 12 months.

Current automation maturity is strongest in AML checks (36%) and document generation (34%), but the report highlights significant untapped opportunity in higher-impact financial workflows. Only 30% of leaders are actively focused on reducing revenue leakage across billing and collection cycles, a gap Actionstep identifies as a direct threat to cashflow and margin.

“Client lifecycle management, from onboarding through to final invoice, is where profitability is won or lost,” said Tromp. “Automation in billing, time capture, and collections isn’t just an operational improvement; it is revenue protection. Midsize firms that focus automation on these high-impact workflows will protect margin while scaling revenue, without simply adding headcount or overhead.”

AI adoption is accelerating, but integration lags behind experimentation

AI adoption among UK midsize firms has tripled year on year. In 2025, just 8% of firms reported active use of legal-specific AI tools. In 2026, that figure has risen to 26%. General generative AI use has also grown sharply, with the proportion of firms actively using AI in parts of their business rising from 13% to 24%.

However, the research reveals that adoption remains largely fragmented. Nearly two-thirds (64%) of leaders say AI use is discretionary to individual staff members rather than embedded into firm-wide workflows. Only 4% report AI being widely integrated across their systems and processes.

Critically, 36% of leaders say they do not know how their clients feel about AI being used in service delivery, which is a transparency gap that carries both reputational and commercial risk.

“AI will not replace legal expertise, but it will redefine how efficiently lawyers reach judgement and how quickly that expertise is delivered to clients,” said Triona Buckley, CPO, Actionstep. “The opportunity now is to move from experimentation to integration. That includes embedding AI into repeatable workflows, pairing adoption with clear governance, and opening honest conversations with clients about how AI supports speed, accuracy, and cost predictability. Transparency builds trust, not the opposite.”

The roadmap gap: confidence in vision, uncertainty in execution

Despite 65% of leaders saying they have a clear vision for becoming a digitally optimised firm, more than half (52%) identify building a firm-wide technology roadmap as a major challenge. Barriers include cost (47%), lack of strategic clarity (39%), and cultural resistance to change (36%).

The report also notes a growing tension between tool proliferation and system cohesion. In 2025, 38% of firms said they wanted more digital tools. In 2026, 52% believe they already have the right number and 19% feel they have too many. The priority for midsize firms is making existing systems work together more effectively.

“The firms we see succeeding are not necessarily the ones with the most tools, they are the ones with the best-connected systems,” said Tromp. “A single source of truth across matter management, document collaboration, billing, and client communications creates the kind of operational visibility that supports both growth and service quality.”

Key statistics at a glance:

• 66% of leaders cite digital transformation as a top 2026 priority, up from 46% in 2025
• Only 30% prioritise improving client satisfaction as a revenue growth driver
• 63% are implementing or considering automation
• 26% are actively using legal-specific AI, triple the 2025 figure
• 64% say AI use remains individual rather than integrated into workflows
• 55% report friction in compliant client onboarding; 43% in financial and cashflow management
• 45% have limited client feedback mechanisms, up 10 percentage points year on year
