St John’s Church Sidcup was first built in 1844, but as the local population grew, the church was altered and enlarged in various stages, until it was almost totally rebuilt between 1899 and 1902 under the direction of the celebrated church architect George Fellows-Prynne. St John’s is big in scale. Some think it slightly ugly judging by its exterior appearance, but inside its height, and the sense of space generated, makes it an impressive building. The eye is drawn through the statues of saints either side of the chancel screen on to the high altar, and one is taken into a new dimension.

St. John’s, situated just off Sidcup High Street, serves a busy parish. As well as its regular Sunday services, some large community events take place annually, such as the St George’s Day Parade for district scouts and guides, the town’s Remembrance Sunday commemoration, and the Civic Carol Service for this part of the Borough of Bexley. Easily seating 600 people, St. John’s is the largest meeting place in the town, and is used for concerts and other gatherings which require a big venue.

The relighting and rewiring of the church, sensitively carried out by Complete Electrical services in 2008/9, was long overdue, and has transformed the setting for worship and other events.
