Instinctively I thought of the Whitechapel Bell Foundry[1] who made Big Ben and America’s Liberty Bell but I'm not sure if they are still trading. EDIT: They are! (kinda) The London Bell Foundry are fighting to save the original site and keep it running[4]. There's a few old surviving family businesses in the UK though[2]. If you want really old and still operating I would look at the Livery Companies of the City of London. They're not family businesses obviously but the oldest, Worshipful Company of Mercers[3] got its royal charter in 1394 but existed for long before that. How long ago? No body knows for sure but at least 12th century. - 1. https://en.wikipedia.org/wiki/Whitechapel_Bell_Foundry https://en.wikipedia.org/wiki/Whitechapel_Bell_Foundry 2. https://realbusiness.co.uk/the-oldest-family-businesses-in-britain https://realbusiness.co.uk/the-oldest-family-businesses-in-b... 3. https://en.wikipedia.org/wiki/Worshipful_Company_of_Mercers https://en.wikipedia.org/wiki/Worshipful_Company_of_Mercers 4. https://www.thelondonbellfoundry.co.uk/ https://www.thelondonbellfoundry.co.uk/
