The counties and areas for the purposes of the lieutenancies, also referred to as the lieutenancy areas of England and informally known as ceremonial counties, are areas of England to which lords-lieutenant are appointed. Legally, the areas in England, as well as in Wales and Scotland, are defined by the Lieutenancies Act 1997 as "counties and areas for the purposes of the lieutenancies in Great Britain", in contrast to the areas used for local government. They are also informally known as "geographic counties", to distinguish them from other types of counties of England.
The City of Milton Keynes is a unitary authority area with both borough and city status, in Buckinghamshire. It is the northernmost district of the South East England Region. The borough abuts Bedfordshire, Northamptonshire and the remainder of Buckinghamshire.

It was created in 1974 as a district of the non-metropolitan county of Cheshire, and became a unitary authority area on 1 April 1998 under Halton Borough Council. Since 2014 it has been a member of the Liverpool City Region Combined Authority. The borough consists of the towns of Runcorn and Widnes and the civil parishes of Daresbury, Hale, Halebank, Moore, Preston Brook, and Sandymoor. The district borders Merseyside, the Borough of Warrington and Cheshire West and Chester.

Eden is a local government district in Cumbria, England, based at Penrith Town Hall in Penrith. It is named after the River Eden, which flows north through the district toward Carlisle. Its population of 49,777 at the 2001 census, increased to 52,564 at the 2011 Census. A 2019 estimate was 53,253. In July 2021 it was announced that in April 2023, Cumbria will divide into two unitary authorities. Eden District Council will cease and its functions pass to a new authority, Westmorland and Furness, covering the current districts of Barrow-in-Furness, Eden and South Lakeland.
The Borough of Fylde is a local government district with borough status in Lancashire, England. It covers part of the Fylde plain, after which it is named. The council's headquarters are in St Annes. Some council departments, including Planning and an office of the Registrar, were previously located in Wesham, but in 2007 these offices were transferred to the ownership of the NHS North Lancashire Primary Care Trust and have since been replaced by a new housing development. The population of the non-metropolitan district at the 2011 census was 75,757.
Wyre is a local government district with borough status in Lancashire, England. The population of the non-metropolitan district at the 2011 census was 107,749. The district borders the unitary authority area of Blackpool as well as the districts of Lancaster, Ribble Valley, Fylde and Preston. The council is based in Poulton-le-Fylde. The district is named after the River Wyre, which runs through the district.
The Daventry District was from 1974 to 2021 a local government district in western Northamptonshire, England. The district was named after its main town of Daventry where the council was based.
The Borough of Harrogate is a local government district with borough status in North Yorkshire, England. Its population at the census of 2011 was 157,869. Its council is based in the town of Harrogate, but it also includes surrounding towns and villages.

The unitary authorities of England are those local authorities which are responsible for the provision of all local government services within a district. They are constituted under the Local Government Act 1992, which amended the Local Government Act 1972 to allow the existence of counties that do not have multiple districts. They typically allow large towns to have separate local authorities from the less urbanised parts of their counties and originally provided a single authority for small counties where division into districts would be impractical. However, the UK government has more recently proposed the formation of much larger unitary authorities, including a single authority for North Yorkshire, the largest non-metropolitan county in England, at present divided into seven districts.
West Northamptonshire is a unitary authority area covering part of the ceremonial county of Northamptonshire, England, created in 2021. By far the largest settlement in West Northamptonshire is the county town of Northampton. Its other significant towns are Daventry, Brackley and Towcester; the rest of the area is predominantly agricultural villages though it has many lakes and small woodlands and is passed through by the West Coast Main Line and the M1 and M40 motorways, thus hosting a relatively high number of hospitality attractions as well as distribution centres as these are key English transport routes. Close to these is the leisure-use Grand Union Canal.
Structural changes to local government in England have taken place between 2019 and 2021, and will potentially continue in 2023. Some of these changes continue the trend of new unitary authorities being created from other types of local government districts, which was a policy of Communities Secretary Robert Jenrick from 2019. Ceremonial counties will not see any changes to their boundaries, as the Lieutenancies Act 1997 will be amended to reflect the new local government areas that comprise them.
