Mid-market businesses positive about AI investment returns

28th April 2026

Mid-market businesses are feeling overwhelmingly optimistic when it comes to their near-term investment in artificial intelligence (AI), according to new research from BDO, the accountancy and business advisory firm.

The bi-monthly survey of 500 mid-market businesses revealed that the majority (97%) said they expect to see a return on their investment in AI within the next one to four years.

BDO’s survey indicates that this cohort are confident about AI and its benefits, with more than one in five (22%) having invested between £1.01m and £5m in AI tools to date. Nearly half of those polled (44%) said they had already invested between £500.01k and £1m, with around a third investing between £100k and £500k.

Despite comprising less than one per cent of British businesses, the mid-market has an outsized role in the UK economy, accounting for one in three private sector jobs and with revenues equivalent to more than half the value of UK GDP.

Catherine Wilks, Partner at BDO said “Mid-market businesses are often hugely innovative and ambitious. It is positive to see that many have already embarked on their own AI journey and are confident that they will get a return on their investment in the short to medium term.

“A lot of companies are likely prioritising internal use cases such as personal productivity tools and back-office automation but there are potentially many more options to explore in areas such as generative AI, chatbots, speeding up financial reporting processes and fixing fragmented workflows, these could offer even greater efficiencies and higher ROI.

“One significant barrier to taking advantage of AI tools can be a lack of skills, capability or capacity. In many organisations, particularly those at the smaller end of the mid-market, there is often no dedicated in-house expertise to lead AI initiatives, which means businesses need external support to get started. We also know businesses are facing major challenges around access to talent and there will be huge competition to attract people with skills in these areas.

“We are also seeing a varying pace of adoption between sectors. While professional services and retailers are among the industries really ramping up AI use both for internal and client facing processes, other sectors risk being left behind.”
