The Priory Church of St Bartholomew the Great in West Smithfield accepted £3,500 for its role in a T-Mobile advert in which royal family and Archbishop of Canterbury lookalikes dance down the aisle to the song House Of Love by East 17.
The church's rector, the Rev Martin Dudley, said the advert - which became a YouTube sensation - was "part of the celebration of the wedding".
Now it has emerged that the church, which has featured in several films including Four Weddings And A Funeral, charges visitors £4 to enter and £1 to take a photograph. Those wishing to pray can use a side chapel free.
