Being south of the Tees, Holwick lies within the historic boundaries of the North Riding of Yorkshire, but along with the rest of the former Startforth Rural District it was transferred to County Durham for administrative and ceremonial purposes on 1 April 1974, under the provisions of the Local Government Act 1972. In May 2013, the newly registered flag of the North Riding was first unveiled at the village, owed to it being one of the most northerly settlements in Yorkshire.
