With Big Ben’s bell an everpresent reminder of the family firm’s contributions, London’s Whitechapel Bell Foundry, established in 1420, was the oldest family business in Great Britain when it closed in 2017.

Even without its iconic bellmaker, London remains a wellspring for family enterprises, accounting for 34 per cent of the UK’s business population and around 1 million of Great Britain’s 5.5 million private sector businesses. Family-owned firms make up most private sector businesses in the UK, contributing nearly $800 billion to Great Britain’s GDP and employing over 14 million. And London’s GDP is over $600 billion alone.

Here are the Top 10 Largest Family-Owned Businesses in London by revenue:
