In the boundary changes in 1918, the constituency was refashioned as the northern part of the Metropolitan Borough of Paddington. The Borough had incorporated an area formerly included in a detached part of Chelsea parish at Kensal Town, and further population expansion made the north of the Borough even more densely packed, so a shift of the boundary was required. In the end, it was decided to include the whole of the Harrow Road, Queen's Park and Maida Vale wards of Paddington, together with part of the Church ward north of the Harrow Road and Little Venice canal basin.
