The following is a list of towns in England and Wales which formed urban districts under the Local Government Act 1894 in the years following its introduction. For districts formed when the act came into force see: Urban districts formed in England and Wales 1894–95.
Note for table: 'UD' stands for Urban District, 'RD' stands for Rural District, 'MB' stands for Municipal Borough and 'CB' stands for County Borough.

In the period 1896-99 sixty urban districts were formed and twenty-two abolished, a net increase of 38, bringing the total number of urban districts to 813.

In the 1900s forty-six urban districts were formed and forty-one abolished, a net increase of 5, bringing the total number of urban districts to an all-time high of 818.
