There are many variations in culture and language in the different parts of the United Kingdom. This is seen in differences in architecture, in some local customs, in types of food, and especially in language. The English language has many accents and dialects. These are a clear indication of regional differences in the UK. Well-known dialects in England are Geordie (Tyneside), Scouse (Liverpool) and Cockney (London). Many other languages in addition to English are spoken in the UK, especially in multicultural cities.

In Wales, Scotland and Northern Ireland, people speak different varieties and dialects of English. In Wales, too, an increasing number of people speak Welsh, which is taught in schools and universities. In Scotland Gaelic is spoken in some parts of the Highlands and Islands and in Northern Ireland a few people speak Irish Gaelic. Some of the dialects of English spoken in Scotland show the influence of the old Scottish language, Scots. One of the dialects spoken in Northern Ireland is called Ulster Scots.
