2019–2023 structural changes to local government in England in the context of "Westmorland and Furness"

Dorset is a unitary authority area within the larger ceremonial county of Dorset, South West England. It covers the entire ceremonial county with the exception of Bournemouth, Christchurch and Poole in the south-east. The largest settlement is Weymouth, and the administrative centre is Dorchester.

The unitary authority area was formed on 1 April 2019 during a local government restructure. Prior to this, Dorset was a non-metropolitan county containing six non-metropolitan districts, and was governed by a county council and six district councils. The unitary authority area was created by abolishing the county, districts, and their councils, and establishing a new non-metropolitan county and a new non-metropolitan district, each with the same area as the former districts of East Dorset, North Dorset, Purbeck, West Dorset, and Weymouth and Portland. The area of the sixth former district, Christchurch, was incorporated into the new unitary authority area of Bournemouth, Christchurch, and Poole. The new Dorset Council was constituted as a non-metropolitan district council with the responsibilities of a non-metropolitan county council. The first elections to the council took place on 2 May 2019.

North Yorkshire is a unitary authority area in the ceremonial county of North Yorkshire, England. It covers the majority of the North York Moors, the Vale of Mowbray and Vale of York, and the Yorkshire Dales. It does not include the north-east of the ceremonial county or the unitary authority area of York. The largest settlement is Harrogate, and the administrative centre is Northallerton. North Yorkshire is the largest local government area in England, with an area of 3,103 square miles (8,037 km).

The unitary authority area was formed on 1 April 2023 during a local government restructure. Prior to this, North Yorkshire was a non-metropolitan county containing seven non-metropolitan districts, and was governed by a county council and seven district councils. The creation of the unitary authority area was achieved by abolishing the seven districts and their councils, creating a new district covering the entire area of the non-metropolitan county, and giving North Yorkshire County Council the responsibilities of a district council in addition to its existing county council responsibilities. The county council chose to rename itself North Yorkshire Council as part of the restructure. The first elections to the reconstituted authority took place on 5 May 2022, and it took on district council responsibilities on 1 April 2023.

Cumberland is a unitary authority area in the ceremonial county of Cumbria, England. It covers the north-western part of Cumbria, including the west of the Lake District. The city of Carlisle is the largest settlement and the administrative centre. The unitary authority area covers the majority of the area of the historic county of Cumberland, from which it takes its name, but does not include the area around Penrith.

The unitary authority area was formed on 1 April 2023 during a local government restructuring which abolished the non-metropolitan county of Cumbria and its six districts. Cumberland has the same area as the former districts of Carlisle, Allerdale, and Copeland, being constituted as a non-metropolitan county and coterminous non-metropolitan district with the same area as the former districts. The three remaining districts of Cumbria were merged into Westmorland and Furness. It remains part of Cumbria for ceremonial purposes. Prior to the local government reforms of 1974, which created Cumbria, Carlisle was a county borough and the remainder of the area was within the administrative county of Cumberland.

West Northamptonshire is one of two unitary authority areas in the ceremonial county of Northamptonshire, England. It contains the county town of Northampton, as well as the towns of Daventry, Brackley and Towcester, and the large villages of Brixworth and Long Buckby; the rest of the area is predominantly agricultural villages though it has many lakes and small woodlands.

West Northamptonshire was created in 2021 as part of local government restructuring from the previous non-metropolitan districts of Northampton, Daventry and South Northamptonshire.
