CFO AI Optimism Hits 73% - But Consulting's Billable Problem Remains Unsolved

The numbers from Deloitte's latest quarterly read on UK corporate sentiment are hard to argue with. Conducted between 1 and 13 July 2026 across 58 CFOs, including the finance directors of 10 FTSE 100 companies and 21 FTSE 250 firms, the survey found that 73% are now optimistic that AI will materially improve their business performance. That compares to 59% at the end of 2025 and just 39% in Q3 2024. Nearly double in roughly two years. The trajectory is steeper than almost anything else Deloitte tracks in its quarterly pulse.

The investment intentions are equally stark. Nearly all respondents, 96%, expect digital technology spending to rise across UK businesses over the next five years, with 93% forecasting that uptick within the next 12 months alone. Half already expect productivity gains before the end of the year. And 78% link their technology investment directly to expectations of improved business performance.

So the demand side of the consulting market has rarely looked more favourable on paper.

The gap between sentiment and signed mandates

Here is where it gets uncomfortable. CFO optimism about AI is not the same thing as consulting revenue. The Deloitte data itself hints at the friction: while 96% expect more digital investment broadly, only 50% expect productivity gains over the next 12 months. That 46-point gap measures how many finance chiefs believe in AI's long-run potential while remaining cautious about near-term delivery.

The Management Consultancies Association found that 77% of UK consulting firms have already integrated AI into their own systems, with 76% deploying it for research tasks and 68% increasing automation. Firms are using the tools. The question is whether clients are paying consulting day-rates for work that AI is increasingly compressing into hours. Pricing models built on billable time face a structural problem that CFO optimism does not resolve.

Source Global Research's 2026 survey found UK consulting buyers are roughly three times more likely to say they are determined to use generative AI than they were 12 months earlier. Determined to use it themselves, not necessarily to pay someone else to do it for them. That distinction is where advisory pipelines get thin.

Formation data tells its own story

AI Business Dispatch analysis of Companies House data shows 3,247 new SIC 70.22 (management consultancy) companies registered in Q3 2026, a drop of 74.6% on the prior period. On the brand side, UK Class 35 trademark filings tracked by the IPO came in at 3,526 in the same quarter, down 67.4% period-on-period. Both cohorts tend to lead economic activity by six to twelve months. A supply contraction of that scale, arriving just as CFO demand sentiment is peaking, is either a healthy shakeout of undercapitalised entrants or a warning that the people closest to the market are reading the economics differently from the CFOs. Probably both.

The trademark figure carries a separate signal. As of July 2026, 98.2% of active SIC 70.22 companies hold no Class 35 trademark. Nine in ten of the UK's management consultancies are operating without registered brand protection in the primary class for business services. In a market where AI tools are commoditising the deliverable and making it easier than ever to replicate a proposition, that is an exposure most firms are not pricing.

Recruitment's parallel compliance crunch

For the recruitment and HR advisory sector sitting adjacent to consulting, a separate pressure is arriving from the regulatory direction. The ICO's 'Recruitment Rewired' project, which ran between March 2025 and January 2026 and engaged over 30 employers, found that most organisations using AI to screen and rank candidates did not believe they were engaged in automated decision-making at all. The ICO concluded several of them were wrong about that.

Final ADM guidance from the ICO is expected this summer, following a consultation that closed in May. Once published, it will carry weight in any enforcement action. The Data (Use and Access) Act 2025, which came into force on 5 February 2026, replaced the near-total prohibition on significant automated decisions with a permissive but safeguard-heavy regime. Recruitment agencies and HR consulting firms deploying AI screening tools need their Data Protection Impact Assessments in order before the guidance lands, not after.

Over 70% of organisations anticipate increasing their use of AI and automation in hiring over the next five years, per ICO research. That is a large and growing compliance surface for the HR advisory sector.

What the CFO data actually commissions

Back to the Deloitte survey. Cost reduction remains the top CFO priority, even as the mood has shifted: 53% cited it in Q2, down from 68% at the start of the year, but still the single biggest agenda item. The number hoping to expand into new products or markets jumped 12 points to 37%. That is an acquisition and growth mandate, not just an efficiency mandate.

For consulting firms, that combination, cost pressure easing slightly and growth ambitions rising, is traditionally good for advisory mandates: strategy work, M&A support, new-market entry. The problem is that "traditionally" is doing a lot of work in that sentence. AI is compressing the research and analysis layers that junior teams used to bill. What remains is judgment, relationship, and accountability. Firms that have restructured around those three things will convert the CFO optimism wave. The ones still selling time will find the numbers do not add up.
