London Adult Party Club, or LAPC, has organised adult parties for twenty-five years by its own account, and runs them in East London.

Its stated point of difference is who it lets in: unlike many swingers' parties, it welcomes single men, single women and couples to all of its events. Parties are advertised a few at a time on its own dates page, with the hostesses attending named there, and entry is described as a contribution rather than a ticket price — single men pay the most, couples considerably less, and single women come free.
