The UK has one of the largest economies in the world, usually placed around sixth by output. Its shape is unusual among big economies: overwhelmingly services, lightly industrial, and concentrated on a single city to a degree that has become a political problem.
What Britain actually does
Roughly 80% of output is services — the highest share of any G7 economy. That covers:
- Financial and professional services — banking, insurance, law, accountancy, consultancy. The City of London is one of the two largest financial centres in the world.
- Creative industries — television, film, music, advertising, video games, publishing. A genuine British strength and a substantial export earner.
- Higher education — international students are one of the country’s largest single exports.
- Retail, hospitality and tourism.
Manufacturing is around 9% of output — small by share, though the absolute figures are still significant in aerospace, pharmaceuticals and cars. Agriculture is under 1%.
The London problem
London and the South East generate a wildly disproportionate share of national output, and the gap between the richest and poorest parts of the UK is the widest in any large European economy. Parts of London have output per head several times that of parts of Wales, the North East or Cornwall.
This is not new. It is the long tail of deindustrialisation: the regions built on coal, steel, shipbuilding and textiles lost those industries between the 1960s and 1980s and were never given a replacement of comparable scale.
Successive governments have promised to fix it — the Northern Powerhouse, the Midlands Engine, “levelling up” — and the gap has not meaningfully narrowed.
The recent record
Britain’s central economic problem since 2008 has been productivity. Output per hour worked has grown far more slowly than in the decades before the financial crisis, and more slowly than in comparable economies. Because wages ultimately track productivity, this is why real pay stagnated for well over a decade — an experience without precedent in modern British history.
The financial crisis, a decade of austerity, Brexit, the pandemic and the 2022 energy shock have all been blamed, in proportions that depend entirely on the politics of whoever is doing the blaming.
How it is run
The Chancellor of the Exchequer sets tax and spending, announced in an annual Budget — traditionally with the Chancellor photographed outside Number 11 holding a red despatch box.
The Bank of England has been independent since 1997 and sets interest rates through its Monetary Policy Committee, with a target of 2% inflation. The Office for Budget Responsibility, created in 2010, produces the independent forecasts against which the Chancellor’s plans are judged — a body whose importance was demonstrated in 2022, when a mini-budget delivered without an OBR forecast triggered a bond market crisis and brought down a prime minister in seven weeks.
The debt
Public debt is around the size of annual national output, a level not seen since the early 1960s, having risen sharply through the financial crisis and again through the pandemic. Whether this matters, and what should be done about it, is the central dividing line in British economic politics.
