List of urban areas in the United Kingdom
The detailed methodology of the process used by ONS in 2011 is set out in 2011 Built-up Areas - Methodology and Guidance, published in June 2013. In reporting the results of the 2011 UK census, ONS use the term "built-up area" rather than the term "urban area" used for previous censuses. However, they state that the criteria used to define "built-up area" are the same as those used previously, as follows:
"..the definition follows a ‘bricks and mortar’ approach, with areas defined as built-up land with a minimum area of 20 hectares (200,000 m2), while settlements within 200 metres of each other are linked. Built-up area sub-divisions are also identified to provide greater detail in the data, especially in the larger conurbations."
In reporting the 2001 census, ONS gave a clearer definition of the term "built-up" as follows:
"This comprises permanent structures and the land on which they are situated, including land enclosed by or closely associated with such structures; transportation corridors such as roads, railways and canals which have built up land on one or both sides, or which link built-up sites which are less than 200 metres apart; transportation features such as airports and operational airfields, railway yards, motorway service areas and car parks; mine buildings, excluding mineral workings and quarries; and any area completely surrounded by builtup sites. Areas such as playing fields and golf courses are excluded unless completely surrounded by builtup sites..."
A conurbation is formed when cities and towns expand sufficiently that their urban areas join up with each other. This process has happened many times in the United Kingdom. In many cases, there are differences of interpretation as to the limits of a conurbation - where it begins and ends. For the purposes of consistency, the list on this page uses the Office for National Statistics definition of built-up areas (previously defined as urban areas).

There is a spectrum that can be drawn between the conurbations that have a clear 'head' (such as Bristol and Leicester) to those that do not, known as multi-centred conurbations (such as Bournemouth/Poole and Teesside), via ones that are more borderline (West Midlands). In the case of the West Midlands, for example, the largest city, Birmingham did expand massively and is now considered to include areas that were formerly independent towns, such as Sutton Coldfield. However, here it stopped, with the Black Country and Wolverhampton retaining strong identities.
There are also various places where whilst not actually running into each other, the amount of development in a large area is substantial. Heavily built up areas of this type include :
- West Yorkshire and South Yorkshire, which are all heavily built up but not entirely devoid of countryside (both are metropolitan counties).
- The area consisting of Greater Manchester, Merseyside and parts of Cheshire (mainly Halton (borough) and Warrington) is heavily built up and considered by some to be a conurbation
- The London Commuter Belt consisting of Greater London and large densely populated parts of the home counties is heavily built up and is considered one of the world's largest cities.
- Cardiff/Newport, consisting of the cities of Cardiff and Newport, Cwmbran, much of the eastern South Wales Valleys with towns such as Risca, Pontypool and Caerphilly and part of the Vale of Glamorgan including Penarth and Barry.
- The Nottingham-Derby Metropolitan area which mainly consists of three large conurbations, the Nottingham Urban Area, the Derby Urban Area and the Mansfield Urban Area.
