In 1889, the area of the Metropolitan Board was reconstituted as the County of London, and Bermondsey was transferred to the new county. In 1900, the County of London was divided into twenty-eight metropolitan boroughs. The parish became the core part of the Metropolitan Borough of Bermondsey, which also covered the parish of Rotherhithe, and the area of the St Olave's District Board of Works (consisting of the two parishes of Southwark St John Horsleydown and Southwark St Olave and St Thomas). A borough council replaced the vestries and board, and in 1904, all four parishes in the borough were merged as the single civil parish of Bermondsey.
