Sharp increase in ‘zombie’ companies in UK mid-market
The number of UK mid-sized businesses at risk of becoming a ‘zombie’ company has risen, as rising costs and challenging economic conditions leave little breathing room for growth, according to new research from accountancy and business advisory firm BDO.
In the last 12 months, one in six mid-sized businesses (15.9%) have been deemed to be at risk of being so-called ‘zombie’ companies – an increase of 3.5 percentage points versus the previous year’s figures.
Zombie companies are those that generate just enough cash to continue operating and service their debt but not to invest in growth.
The BDO tracker, which analysed more than 20,000 businesses with a turnover between £10m and £500m, found that very few sectors have been able to buck the trend, with all but two showing a notable increase in the number of ‘at risk’ businesses.
Real estate has the highest number of ‘at risk’ companies this year, with a quarter of the sector (25.1%) exhibiting signs of a zombie business. This is an increase of 10.1 percentage points versus the prior year, highlighting the ongoing impact that relatively high interest rates, , economic uncertainty and supply chain disruptions are having on the sector.
Leisure & hospitality has dropped one place to second, with 23.4% of businesses ‘at risk’. While mining and quarrying is the biggest riser in third, with the percentage of ‘at risk’ businesses in the sector increasing by 11.9 percentage points to 20.7% due to rising energy and input costs and weakening global demand for raw materials.
Ben Peterson, partner at BDO LLP, said: “In light of the challenging economic conditions over the past 18 months, it’s no surprise that the number of mid-market businesses at risk of becoming zombie companies is on the rise.
“Although many have managed to navigate a difficult post-Covid environment, rising borrowing costs and inflationary pressures have significantly impacted their financial stability. Some of these companies cannot afford to wait for market conditions to improve, particularly in light of upcoming increases to employers’ national insurance contributions, the national minimum wage and the national living wage, all of which will have a direct impact on profitability.”
Geographically, Greater London, the North East and the South East have the highest proportion of businesses at risk. Of the 12 regions, 10 have between 13%-18% of ‘at risk’ businesses. Greater London has the highest concentration (17.8% and up from 13.3% in 2024), followed by the North East (17.6%).
Ross McWhir, director at BDO, added: “In general, mid-sized businesses have been hugely resilient in the face of geopolitical tensions, Covid-19 and Brexit. Over the last decade, these businesses have significantly contributed to UK GDP and overall employment numbers.
“However, while resilient they are not invincible. There is now a proportion of businesses that will require more transformational action to ensure they can prime themselves to survive the coming economic turbulence – whether that’s short-term actions such as challenging the cost base and undertaking a rapid assessment of the business’ pricing strategy, to more medium-term actions, including rightsizing the organisational structure or divesting underperforming areas of the business. Addressing these issues now will be fundamental to the business’ longer-term health and protect shareholder value.”
BDO’s tracker defines businesses as at risk if they had a five-year annual compound turnover growth rate of less than 5% and an interest cover ratio in their latest financial year of less than two times. The data analysed was sourced from the latest publicly available financial data per Companies House.
