Borough status is granted by royal charter to local government districts in England, Wales and Northern Ireland. The status is purely honorary, and does not give any additional powers to the council or inhabitants of the district. In Scotland, similarly chartered communities were known as royal burghs, although the status is no longer granted.

In the Middle Ages, boroughs were settlements in England that were granted some self-government; burghs were the Scottish equivalent. In medieval England, boroughs were also entitled to elect members of parliament.

Metropolitan boroughs are a subdivision of a metropolitan county. These are similar to unitary authorities, as the metropolitan county councils were abolished in 1986. Most of the powers of the county councils were devolved to the districts but some services are run by joint boards and organisations.
