One in Three UK Start-ups Now Registered After Working Hours

More than 55,000 businesses were registered outside traditional working hours last year, as growing numbers of Britons turned evenings, nights and lunch breaks into opportunities to build companies alongside their day jobs.

New analysis of 173,979 company registrations between 2023 and 2025 by 1st Formations found that nearly a third (31.6%) of all new businesses were incorporated between 5pm and 9am, highlighting the rise of what researchers describe as “after-hours entrepreneurship”.

The figures offer a snapshot of a changing workforce, where side hustles are increasingly viewed not as passion projects but as a practical way to improve financial security amid ongoing economic pressures.

Research from Scottish Widows and Monzo points to the scale of the shift. Nearly one in five UK adults now runs a side hustle, rising to one in four among Generation Z. Among those with additional income streams, 39% say they do so to improve their financial situation, with the average side hustle generating £470 a month.

The registration data suggests many aspiring entrepreneurs are fitting business-building around full-time employment rather than leaving established careers to launch startups. Weekday activity peaks between noon and 2pm, indicating that thousands of workers are using lunch breaks to complete company registrations and take their first formal step into business ownership.

The trend is particularly pronounced during the middle of the week, with Tuesday and Wednesday emerging as the most popular days for incorporations. While weekend registrations remain lower overall, Sunday saw almost as many after-hours registrations as those made during conventional working hours, suggesting the distinction between work and entrepreneurship is becoming increasingly blurred for many founders.

Graeme Donnelly, founder and CEO at 1st Formations, said: “We’re seeing a generation of founders who aren’t taking a reckless leap into the unknown; they’re building a business while the rest of the world sleeps.

“AI is letting founders launch faster and more cheaply, without leaving their day jobs or committing to expensive office space, and from wherever and whenever suits them. It has completely transformed the barrier to entry. Coding, copy, admin – it handles more than ever before. You can be a CEO by sunrise.”

The findings point to the growing role of technology in lowering the barriers to entrepreneurship. From website creation and marketing to administration and customer support, AI tools are enabling founders to launch businesses with fewer resources and less upfront investment than previous generations required.

For many, the process begins not with a dramatic resignation or a major funding round, but with a spare hour in the evening or a quick task completed between meetings.

The lunchtime registration peak identified in the data suggests a distinct cohort of “lunch break founders” has emerged, using short windows during the working day to move business ideas from concept to reality.

Donnelly believes the trend reflects a broader transformation in how businesses are being built.

“2026 is the year of the specialised, agile startup. Whether it’s a Gen Z founder registering a tech startup at 2am or a mid-career professional incorporating a consultancy after the kids are in bed, the pattern is consistent – the UK’s entrepreneurial spirit doesn’t punch a clock.”
