The Decision Economy
THE MID-MARKET HEAVYWEIGHT
The UK mid-market, those with 50–499 employees, form the backbone of the UK economy. Collectively, they generate just over one fifth of private-sector Gross Value Added (“GVA”) and employ over 5.26 million people, despite representing only a small fraction of the companies. Over the past five years, the mid-market has expanded steadily, creating 315,000 jobs and achieving productivity growth ahead of both SMEs and large corporates. This broadly under-recognised group of businesses has proven its skills in agility and innovation, often outpacing the wider economy on key metrics. Research shows that the mid-market faces significant structural challenges. They often lack a unified voice in policy debates and support from lenders or Government initiatives. As these companies grow in scale and complexity, many experience strain on leadership capability and management processes, making it harder to navigate new markets or disruptions. A bespoke 2026 survey of 601 mid-market leaders reveals that nearly 70% experience frequent delays in major decisions, caused by factors like data
paralysis, complex internal approvals, and caution around uncertainties. These decision-making bottlenecks mean mid-tier firms often respond too slowly to crises or fast-moving opportunities. Crucially, the opportunity cost of slow decision- making is stark. Only 30% of mid-market leaders feel they make decisions as fast as they should – the rest admit to 1–2 week delays on average. In fact, our survey found that 77% of executives believe acting sooner on their last major decision would have improved the outcome, and over 40% say they missed out on a double-digit boost in revenue or savings by waiting too long. By quantifying these effects, we find that accelerating decision-making across the UK mid-market could unlock up to £13.7 billion in additional GVA annually. This equates to a productivity uplift of approximately 2.4% of the mid-tier’s current contribution to the economy, or around 0.6% of UK GVA. The gains would be distributed across all regions and industries but especially concentrated in knowledge-intensive sectors (like technology
and business services) and the larger businesses (those closer to 500 employees) which have the most at stake. For mid-market leaders and their advisers, these findings carry a clear message - speed matters. In today’s environment of inflation, labour shortages, and rapid technological change, the ability to decide and execute quickly is becoming a key competitive differentiator. Firms that consistently move earlier on big decisions build a performance edge that compounds over time. Fortunately, these businesses are inherently agile and entrepreneurial. With the right support and focus on a few critical levers including better data analytics and clearer government policy signals, they can overcome the “decision drag” and realise their growth potential. This report explores the mid-tier’s economic weight, recent performance, decision-making challenges, and the size of the opportunity if these companies can seize opportunities faster.
