The Act imposed a fine on any person who attended a conventicle (any religious assembly other than the Church of England) of five shillings for the first offence and ten shillings for a second offence. Any preacher or person who allowed their house to be used as a meeting house for such an assembly could be fined 20 shillings and 40 shillings for a second offence.
