What is the difference between the UK, Great Britain and England?
Short answer
The UK is the sovereign state, made up of England, Scotland, Wales and Northern Ireland. Great Britain is the island containing the first three — it excludes Northern Ireland. England is a single nation within both. The British Isles is a geographic term that also includes the Republic of Ireland.

The full name of the state is the United Kingdom of Great Britain and Northern Ireland, which is itself the explanation: Great Britain plus Northern Ireland.
Great Britain is a landmass — the largest island in Europe — containing England, Scotland and Wales. When a law or a statistic refers to 'Great Britain' rather than 'the UK', it is deliberately excluding Northern Ireland, which happens more often than people expect because Northern Ireland has separate legislation on many matters.
England is one nation within the UK and by far the largest, with about 84 per cent of the population. Using 'England' to mean the UK is both a social error and frequently a factual one, because health, education, housing and much of justice are devolved and English rules often do not apply elsewhere.
The British Isles is a geographic archipelago that includes Great Britain, the island of Ireland and thousands of smaller islands. It therefore includes the Republic of Ireland, an entirely separate sovereign state, which is why the term is contested in Ireland. 'Britain and Ireland' is the neutral alternative.
Two further categories confuse things. The Isle of Man and the Channel Islands are Crown Dependencies — self-governing, with their own laws and tax systems, and not part of the UK. The fourteen British Overseas Territories, from Gibraltar to the Falklands, are also not part of the UK.
