British businesspeople investment in ai coins gears mixed outcomes

UK enterprises spend GBP £320 billion on AI but half fail to deliver

Tue, 18th Nov 2025

Britain's largest enterprises have increased their annual spending on artificial intelligence to more than GBP £320 billion, with over GBP £66.1 billion of that channelled to external consultants. Recent research suggests that half of these AI projects are failing to meet expectations, reflecting ongoing concerns over effectiveness and return on investment for businesses.

AI budgets grow

A survey of 1,000 senior decision makers at organisations with annual technology expenditure over GBP £20 million revealed that 90% had raised their AI budgets in the past year, with the majority upping their spend by between 21% and 50%. The average UK enterprise in this bracket now spends GBP £39.2 million on AI annually, with GBP £8.4 million dedicated to consultancy fees.

The collective spend across the UK's 8,335 large enterprises amounts to an estimated GBP £326.8 billion, demonstrating the scale of commitment to AI. Of this, more than GBP £66.1 billion is allocated to external consultancy services for AI initiatives.

Mixed project outcomes

Despite rising investment, most organisations are struggling to realise full value from their AI outlays. The survey data shows that half of all AI projects do not deliver as expected. Only 45% of these initiatives have clear success metrics defined at the outset, leading to challenges in measuring impact or achievement.

One third of AI projects reportedly take more than six months to begin delivering substantive results. Over-emphasis on technological solutions at the expense of business outcomes was identified as the most common reason for failure, cited by 30% of respondents.

Consultancy spend dynamics

The research highlights a heavy reliance on consultancy for AI deployment, yet firms cite limited returns for these outlays. For enterprises spending over GBP £100 million on technology, the average annual investment in AI alone reached GBP £53.08 million, with consultancy bills averaging GBP £11.30 million per company.

By comparison, more than one third-31%-of enterprises spend less on all other technology combined than these top-tier firms commit just to consultants for AI projects each year.

New consultancy launches

Against this backdrop, Valliance, an AI-focused consultancy, has announced its launch with private equity funding of USD $15 million and three signed contracts with global brands. The company intends to offer a model based on value delivered, charging fees only when projects achieve specified business outcomes, diverging from traditional billable hours practices prevalent in the sector.

Valliance's founding team comprises Tarek Nseir, Anita Rajdev, and Rad Parvin, all of whom have backgrounds in digital transformation, commercial leadership, and global data strategy, respectively. The consultancy has assembled a 15-person team with expertise spanning system architecture, product design, and data analytics.

"The world is in an AI arms race. Leaders who want to ensure success for the next decade must derive value from the technology now or be left behind - and they need the right advice and guidance to cut through hype and achieve this goal. But the legacy consulting model is broken. The big firms rely on outdated practices that drive up business AI spend and create waste, rather than value. Billions are being spent on science projects and initiatives that will never work in production, and that's costing enterprises and the economy. Valliance is made for this moment. We've drawn from the very best in consulting, tech, data, design and industry to create something entirely new," said Tarek Nseir, Chief Executive Officer, Valliance.
