The new rules will apply to all adult entertainment industry jobs involving physical contact, including sauna workers, escorts and massage parlor workers, to make sure that if physical contact is required it is not of a sexual nature.
Employers providing illegal services will have their access to the website withdrawn and will be reported to the police.
"While we have a duty to advertise all legal vacancies, we must ensure that Jobcentre Plus is not used as a gateway to illegal activities," Secretary of State for Work and Pensions Peter Hain Hain said. "The crackdown I'm announcing today will ensure that unscrupulous employers cannot dupe our customers. It's time we nailed those that are intent on playing the system."
Jobcentre Plus is part of the government's Department for Work and Pensions, offering employment and benefit services for people based on "Work for those who can, support for those who cannot."
Jobcentre Plus works with more than 275,000 employers to place 17,000 people into work every week. Each week more than 400,000 vacancies are listed and more than 4 million job search requests are received.
Currently, employers are required to provide a full job description, and job openings can be labeled as unsuitable for applicants under 18. Under the new rules, employers will be required to sign a statement confirming that the jobs advertised do not involve any illegal sexual services before the job can be offered.
