Near the church door is a large, traditional, font in which babies are baptised.

There are two stained glass windows, one is a gift from the architect and the other was given by Sir Theodore H L Brinckman Bart.

St. Paul's is shared by the Serbian Orthodox Church, being named St. Nicholas by them.

The most prominent feature of the church interior is an iconostasis covered with icons.

The West Wycombe Revels, a large village fete, used to be held in the grounds around the church each summer.
