Storvreta belongs to Ärentuna Parish in the Church of Sweden. The 14th-century Ärentuna Church is located some 5 km to the west of Storvreta, and there is also a chapel in the village itself. In addition, there is an ecumenical church, Lyckebokyrkan, which belongs to the Uniting Church in Sweden (formerly the Mission Covenant Church of Sweden and the Baptist Union of Sweden), and which was built in 1982. When Lyckebokyrkan had been built, the old Mission Covenant Church, commissioned to be built by J E Blomqvist in 1908, was torn down. The old Baptist chapel from 1895 was also levelled at this time.
