In 1872 sanitary districts were established, giving public health and local government responsibilities for rural areas to the existing boards of guardians of poor law unions.

The Milton Keynes Development Corporation was established to oversee construction of the new town, and Newport Pagnell Rural District Council lost its town planning responsibilities in that area to the development corporation.

In 1926 the council bought a large house at 7 Station Road in Newport Pagnell for £1,000, converting it to become its offices and meeting place.

Newport Pagnell Rural District was abolished under the Local Government Act 1972, with the area becoming part of the non-metropolitan district of Milton Keynes under Buckinghamshire County Council on 1 April 1974.

(The district subsequently gained Borough status, became an independent unitary authority and – in 2022 – became the City of Milton Keynes.)
