The adoption of AI could unlock £105bn of revenue for UK medium-sized companies by 2030, HSBC research finds.

Artificial intelligence could generate more than £105 billion in extra revenue for UK medium-sized companies by the end of the decade, according to a new economic model that highlights how AI is rapidly reshaping the country’s business landscape.

The study, carried out by the Center for Economics and Business Research (Cebr) on behalf of HSBC UK, suggests that businesses embedding AI across their operations are beginning to outpace competitors who are slow to adopt the technology.

Alongside this report, HSBC UK launched a £5 billion AI & Productivity Financing Initiative which aims to help businesses invest in the technology, skills and systems needed to use AI at scale.

The analysis focuses on Britain’s medium-sized businesses, companies with an annual turnover of between £15 million and £300 million, which are often described as the “engine room” of the UK economy due to their ability to combine the agility of small firms with the investment power of large organisations.

Around 35,000 such companies operate across the UK. By 2025 they produced 23 percent more per worker than the wider economy, highlighting their growing importance as a driver of productivity and growth.

Research shows that AI is increasingly becoming the dividing line between fast-moving firms and those that risk falling behind.

Two years ago, only about 35 percent of mid-sized companies were using AI in some way. By the end of 2025 that number had increased significantly to 55 percent, reflecting the widespread adoption of large modeling languages, advanced analytics and workflow automation tools across many industries.

However, the report notes that a clear distinction exists between businesses that are exploring AI and those that are deeply embedded within core business operations.

About 24 percent of mid-sized companies are now considered “productivity adopters”, organizations that integrate AI into critical processes such as forecasting, supply chain management, reporting, customer engagement and operational decision-making.

These companies are seeing measurable improvements in both productivity and revenue.

According to research, firms that integrate AI into their operations experience an average increase of four percent in revenue per employee.

For a typical medium-sized business, this can translate to £4.5 million more in revenue and around £1.3 million more economic value over four years compared to companies that haven’t adopted the technology.

If adoption continues at its current pace, the cumulative impact could be significant. Modeling suggests that AI-driven productivity gains across the mid-market could add £105 billion in additional revenue and £31 billion in economic impact to the UK economy by 2030.

Looking ahead, research estimates that the adoption of AI among medium-sized firms could generate more than £500 billion in additional revenue by 2050, although gains are expected to slow as the technology becomes more widely embedded across industries.

James Cundy, managing director and head of corporate finance and profitability at HSBC UK, said the findings highlight the growing importance of AI investment for business competitiveness.

“Medium-sized businesses play a key role in the UK’s growth,” he said. “Our findings suggest that the adoption of AI can strengthen one of the key engines of economic growth.

“The opportunity is significant, but it takes confidence to invest. We are focused on supporting businesses as they invest in the technology, skills and innovation that will shape the UK’s next phase of growth.”

With the new funding programme, HSBC aims to offer businesses access to funding on commercial terms to support AI investment in all areas including digital infrastructure, data systems, workforce training and automation.

Cundy emphasized that the biggest benefits come from companies that go beyond testing and integrate AI into their decision-making and operational processes.

“The difference between testing and integration is important,” he said. “Businesses that use AI in operations, human resources processes and strategic decisions see measurable improvements in productivity and revenue.”

Economists say the research underlines the growing role of technology in shaping productivity outcomes in the UK economy as a whole.

Nina Skero, chief executive of the Center for Economics and Business Research, said the results suggest the mid-market still has a lot of room to benefit from AI-driven productivity improvements.

“Our research shows that AI is already starting to impact productivity outcomes among mid-sized firms in a meaningful way,” he said.

“However, the manufacturing adopters remain a minority within the middle market. That shows there is still a significant basis for growth. If more companies move from early adoption to deep integration, the combined impact on UK manufacturing and national output could be significant by the end of the decade.”

The report concludes that the speed with which companies move from exploration to full integration will ultimately determine how much of the potential $105 billion opportunity is realized.
