Most productive places in the UK: Londoners do the most for the British economy, says ONS data

Workers in the capital reportedly add the greatest value to the British economy

London is the most productive place in the country

The most productive people in country work in London, according to new data from the Office of National Statistics.

In a study of the UK's 37 subregions, workers in Inner London were found to have provided the most gross-value-added (GVA) to the country's economy — performing almost 50 per cent better than the UK average.

Within London, it's those based in the city's west that have the highest productivity level.

North Eastern Scotland, centred around the business city Aberdeen, is the most productive subregion outside of the south of England, where 8 of the top 10 performing territories are located.

Cornwall and the Isles of Scilly provides nearly 30 per cent less GVA than the UK average, and is 8 points behind West Wales and The Valleys, the next least productive subregion.

The lowest performing NUTS3 region (smaller than the 37 explored before) is Powys in Wales.

As a banking hub and destination of international business, London's place atop the GVA rankings makes sense, as do the large sums of money traded in Aberdeen explain its success.

The BBC has said the high productivity reported in Derby and Swindon is likely driven by their lucrative car manufacturing business — Toyota and Rolls Royce in the former, Honda in the latter.

Regions more dependent on agriculture of tourism are unlikely to have performed well in ONS' GVA measurement, as are those that haven't seen investment for many years.
