All industries in Belfast

Together, property developers, restaurants and eating places and general business services make up the top three industries in Belfast, accounting for 13% of the city's commercial activity. The oldest company we can find in Belfast is Intact Insurance Ireland Designated Activity Company, founded in 1710, with Linen Hall Library not far behind. They're still here, along with hundreds of thousands of others.

The shipyard that built the Titanic still towers over Belfast, where linen and shipbuilding have given way to film studios, cybersecurity firms and a lively hospitality trade. All of them are in our data. Search Belfast businesses in the live tool below, get the full list delivered as an Excel file, or pull the records straight into your own systems through our API.
