Be Church (Barking Elim Church) is on Axe Street, and seen by Streetview in 2024. It presumably replaced or is on the site of a chapel labelled as Independent Chapel on a map of 1873, and on the 1897 25" map as Meeting Room. Mid-20th century maps don't show it as a place of worship. Link.

Older O.S. maps show a Friends' Meeting House on North Street and Queen's Road, at TQ 4402 8438. An old photo of it can be seen here. It survives as Singh Sabha London East Gurdwara. Facebook.

There used to be a Congregational Chapel on Broadway, at TQ 4417 8394. It may be shown on a map of 1873 - it isn't labelled as a place of worship, but it had definitely been built before 1897. It didn't survive in active use to the middle of the last century. Its site lies mostly beneath the smaller building seen in a Streetview from 2025.

St. Erkenwald (2024 Streetview) stands on Levett Road, at TQ 4534 8481. Pevsner, which dates it to 1954-5, says that its predecessor now serves as the church hall, and dates that to 1934. The only available map to show it as a church is the 25" map of 1946, which puts it behind the present church. It isn't visible to Streetview, but there is signage at the side of the present church (2024 Streetview) to the Oasis Centre, which is probably the re-purposed earlier church. Assuming this to be correct, its interior can be seen here.

St. Mary and St. Ethelburga (R.C.) on George Street and Linton Road, as seen by Streetview in 2022. Pevsner dates it to 1979. TQ 4418 8431. Link.
