More than three-quarters of business owners are losing sleep worrying about their company.
The poll also revealed that six in 10 found 2023 as one of their most stressful years yet.
A study of 500 adults who run a firm found generating new business tops the list of the biggest challenges they face.
This was followed by rising operational costs and balancing work with their personal lives.
And 39% are regularly working beyond normal working hours while 34% are sacrificing their weekends taking work calls.
It also emerged that despite 89% believing it’s important to have strong pitching and presenting skills, 59% admit they feel nervous when doing so.
While 55% feel their business would have benefitted if they’d been taught public speaking as a child.
James Holian, head of business banking at NatWest, which commissioned the research, said: “We know that helping business leaders succeed, not just through traditional banking services but with full wraparound business support, is crucial if we want a strong small business sector.
“While it’s never easy running a business, with the right support, we can assist businesses in overcoming challenges and help to drive their business forward.”
The study also found 45% have contended with the rising cost of living, with one in three struggling with the ever-increasing price of goods and services within their company.

James Holian, from NatWest, which has helped 35,000 individuals and businesses through schemes like its Entrepreneur Hub, added:
“Whatever the size of your business, if you’re just starting out, already growing fast or even thinking about scaling, support could help you get there, and help you overcome those challenges, faster.”
