A major new study by UCL researchers has revealed the challenges faced by London’s 1.3m night workers, including pay inequality, health problems, transport difficulties, safety concerns and a lack of workplace dignity.
Night workers, those who typically work between 6pm and 6am, make up around a quarter of London’s 5.3m workforce and 16% of the UK’s night workforce.* They include nurses, bus drivers, security guards, waiters, performers, cleaners and delivery riders and drivers. More than 220,000* commute from outside the capital, and are disproportionately from ethnic minority groups, and/or not born in the UK. Many are women and LGBTQ+.
The Data after Dark project, led by the UCL Social Data Institute and UCL Urban Laboratory, is the most comprehensive study of its kind. Supported by the Mayor of London, the study combines innovative spatial analysis using mobile phone data, surveys of workers and employers, interviews, and in-depth documented conversations with night workers across sectors, to better understand their experiences and working conditions, and to map night-worker activities across the city.
As part of the study, researchers also set out a series of policy recommendations, several of which are relevant to the Employment Rights Bill which is due to make sweeping reforms to UK employment law. The researchers emphasise that the Bill’s success depends on whether it addresses the specific and often overlooked challenges faced by night workers.
Key Findings
Policy Recommendations Summary**
Researchers propose:
Lead researcher, Professor James Cheshire (UCL Social Data Institute) said: “Up to now relatively little data has been gathered on the experiences of night workers because the statistical infrastructure in the UK largely assumes a consistent 9 to 5 working pattern, missing many who work outside those hours.
“Night workers make up a diverse but fragmented workforce that spans multiple sectors, both public and private. This includes most commonly hospitality, food delivery, cleaning, maintenance and security work.”
He added: “London is a vibrant and complex 24-hour metropolis, that relies on those who clean offices, stock shelves and keep deliveries moving while most of us sleep.
“This study highlights the stark differences in their working and economic conditions, that impacts their safety, health and wellbeing. Our series of policy recommendations would go some way to addressing these disparities.”
Professor Ben Campkin and Dr Alessio Kolioulis (UCL Urban Laboratory) led the Data after Dark’s, Voices of Night Workers report, capturing personal stories to inform policy.
“There’s urgency here,” said Professor Campkin. “The Employment Rights Bill going through Parliament proposes landmark reforms to UK employment law — including protections against exploitative contracts, day-one rights to unfair dismissal claims, and improved sick pay. However, if the Bill is to truly be effective, we must understand and act on the lived experiences of night workers, otherwise the legislation may fall short of its promise to ‘Make Work Pay’ for all.”
Matthew Hopkinson, Honorary Professor of Practice and Co-Founder of Didobi, added:
“This research provides the evidence needed to support an often unseen group of workers and businesses.”
Deputy Mayor for Culture and Creative Industries, Justine Simons, said: “Throughout the night 1.3 million Londoners are working hard to keep our city running. Night workers make a crucial contribution across all aspects of London’s culture, hospitality and our wider economy. For too long our knowledge of their experiences has been very limited, so this report is an important step forward, and it shines a light on both the challenges and the opportunities. Working with our partners across the capital we will continue to do all we can to support those working at night, as we build a fairer and better London for everyone.”
Though this project focused on London, the researchers say it offers insights for other cities in the UK and globally.
The project was supported by the Mayor of London and brings together researchers from the UCL Social Data Institute, the UCL Urban Laboratory in The Bartlett Faculty of the Built Environment, the Geographic Data Service and Didobi Limited.

Quotes from night worker interviews (names of night workers have been changed)
Value of night work:
“ I think night workers have huge challenges, and we often undermine [ourselves] because we have our circumstances, like to fulfil our family needs, our financial circumstances, or maybe some other kind of situations we are in, and we compromise our health. We compromise our well-being. We compromise the sense of security and all these things. And I think it needs to come out, it needs to be debated, discussed, so that there should be some policy decisions which are based on evidence.” Ravi, age 35-44, Male, Asian Indian, Retail, 3-5 years in night work.
“We are needed, but we are invisible at the same time.” Amina, 45-54, Female, Black African, Security, 1-2 years in night work.
“The biological clock and the demands of the work do not synchronise […] I suffered because of the 24/7 idea.” Hassan, age 65+, Male, Somali, Hostel for the Homeless, 10+ years in night work.
Financial precarity:
“Our work is rewarding, but not financially. We put ourselves through so much physically, emotionally and mentally, and the pay just doesn’t match up. I love making someone’s night, but I also need to pay my bills.” Leila, age 35-44, Female, White and Asian, Hospitality, more than 10 years in night work.
“No one appreciates the hard work or struggle I do to keep myself afloat during the cost-of-living crises.” Imran, age 35-44, Male, Asian Bangladeshi, Food delivery, 1-2 years in night work.
Safety:
“I’ve been harassed while at work, being a woman and being a woman of colour.” Leila, age 35-44, Female, White and Asian, Hospitality, more than 10 years in night work.
“I think the security of the night workers right now is kind of like optional to the people, to the managers of the company.” Priya, age 25-34, Female, Asian Indian, Customer Service, 6 months-1 year in night work.
