The AI Efficiency Paradox: Revenue at Risk or Margin Opportunity?
Thomson Reuters projects UK lawyers could unlock £2.4bn in productivity gains by 2026, saving roughly 140 hours per lawyer annually — rising to 370 hours over five years.

Thomson Reuters projects UK lawyers could unlock £2.4bn in productivity gains by 2026, saving roughly 140 hours per lawyer annually — rising to 370 hours over five years. At prevailing billing rates, 140 hours of a senior associate's time represents £30,000–£70,000 in annual billing capacity per lawyer that either disappears from the invoice or gets redeployed. Wolters Kluwer's 2026 Future Ready Lawyer survey found 67% of corporate legal departments expect AI to impact billing, yet only 40% of law firms anticipate reducing bills despite efficiency gains. The LawVision survey found 35% of firms have no AI use and 73% haven't experienced meaningful AI productivity improvements — AI-driven revenue compression remains largely theoretical at most firms. Firms billing "AI review" as a line item at 12 minutes are, in effect, creating a hidden client subsidy.
