Camden and the City of London add more to the national economy than almost anywhere else in the UK, according to new research.

The study, carried out by global financial technology group Plus500, used Office for National Statistics (ONS) data collected between 2004 and 2021.

It calculated the Gross Value Added (GVA) per hour worked in different regions, measuring regional contributions to the economy.

Tower Hamlets was ranked as the most economically valuable area in the UK, closely followed by Camden and the City of London in second place, with North Hampshire coming in third.

The study calculated that Camden and the City of London produce £65.9 of GVA per hour worked.

This is likely down to the fact that Camden is home to more than 34,000 registered businesses, although the majority of these are classified as micro businesses with nine or fewer employees.

The highest business counts in Camden were for management consultancies and barristers, while the City of London contributes to the economy with its high-earning businesses, maintaining its reputation as a financial hub for the UK.

In firs place, Tower Hamlets achieved a GVA of £71.9 per hour thanks to its 19,000 registered businesses, most of which are in the professional, scientific and technical sectors.

Tower Hamlets' large number of management consultancies, architectural and engineering firms, and information, communication, wholesale, and retail businesses further add to its solid economic performance.

Other areas in London that reached the top ten were Westminster in fourth place, Hounslow and Richmond Upon Thames coming in joint fifth, Croydon securing seventh, and Lambeth tenth place.

Westminster's success is credited to its 52,000 businesses and industry focused on professional, scientific and technical activities.

Hounslow and Richmond Upon Thames, which jointly ranked fifth, owe their position to their "affluent" area with high property prices and high-revenue businesses, creating a GVA of £57.2 per hour worked.

Croydon's financial, insurance, engineering, digital, tech, and government sectors contribute to its GVA per hour of £52.20.

The area is also considered one of the largest financial centres in the southeast -home to more than 14,000 businesses

Finally, Lambeth's GVA per hour of £47.8 is due to its sectors of creative and digital industries, professional and financial services, life sciences and healthcare and hospitality and tourism.

Other areas in the UK that were among the most economically valuable included Berkshire, placing sixth, West Surrey in the eighth spot, and Swindon coming in at number 9.
