There are a few hundred outsourced workers at Senate House and other University of London buildings in Bloomsbury, including the intercollegiate student halls. Most of the caterers are employed by Aramark; the cleaners, security guards and maintenance by Balfour Beatty Workplace, the services arm of the construction giant. Most are immigrants; from Asia, Africa, Eastern Europe and, overwhelmingly in the case of the cleaners, Latin America.
