Opening in 1865 to the design of Architect George Barnes and serving the Bickley Park estate then being developed by George Wythes, St George's was an imposing structure in a high Gothic style that reflected the confidence of the building going on around it.

The spire was found to be unsafe about 1904 and was rebuilt by Ernest Newton, an architect then very much in vogue, in a plainer style.

The church suffered a huge fire in 1989 during preparations for its 125th anniversary, but was subsequently rebuilt in the original style.
