Soho walk-up
A Soho walk-up is a flat in the Soho area of London used by a female sex worker for prostitution. These flats are usually on the upper floors of buildings above shops and are accessed by a staircase from a door on the street. They have been a distinctive part of Soho’s way of working since the 1960s. Soho has a long history of sex work, dating back to the 18th century, and the scene grew in different ways over the years. In the mid-2000s some walk-ups were bought and turned into other uses, and by 2014 gentrification reduced the number of flats used for prostitution to about 40; today there are roughly a dozen walk-ups left. The area is still known as a red-light district, and prostitution continues in walk-ups.
How a walk-up is set up
Most walk-ups are accessed from a street door and a common stairway, not by a lift. A potential client usually enters through an open street-door, goes up a flight of stairs, and rings a doorbell with a girl’s name on the second door. A sign at street level—often a hand-crafted or fluorescent “model” sign—helps indicate the entrance to the walk-ups. A building may have two or three different walk-ups, each run by one sex worker.
Who works there
Each walk-up typically houses one sex worker and a maid. The maid acts as receptionist, greeting clients, letting them wait, or telling them when the worker will be free. Walk-ups often run on a daily rota, with a different worker on duty each day.
How visits work
There is usually no appointment. A client simply rings the bell to see if the worker is available. Payment goes directly to the sex worker for the service, and a tip to the maid is common.
Is it legal?
The legal picture is complex. A de jure brothel is defined as a place used by more than one person to offer sexual services. A single worker in a walk-up does not by itself make a brothel, but a building with several walk-ups or a flat used by different workers at different times could be treated as part of a brothel. Street solicitation is illegal, and the law covers any public place, including premises open to the public. In practice, walk-ups rely on clients walking in on their own initiative, rather than street solicitation.
Enforcement and changes over time
For much of the late 20th century, police often avoided closing Soho walk-ups, which made enforcement difficult. There have been raids and prosecutions in some cases, especially where trafficking or pimping were alleged, leading to closures. Some closures were later overturned in court when it could not be shown that prostitutes were being controlled. As a result, authorities have sometimes used other tools, like closure orders for drugs or disruption, rather than prosecuting sex-work activities. Overall, the number of walk-ups has continued to shrink with changes in policing and the area’s development.
In sum, a Soho walk-up is a small, stair-accessed flat used by a single sex worker at a time, typically with a maid receptionist, operating in Soho’s historic red-light district. The legal situation is nuanced, and while enforcement has varied, walk-ups remain a recognizable part of the area.
