Space companies in London

London’s space sector combines satellite infrastructure with one of the world’s deepest pools of specialist capital and commercial expertise. Eutelsat OneWeb and Inmarsat anchor a long-established communications industry, while newer companies are building in Earth observation, propulsion, space surveillance and in-orbit manufacturing. What distinguishes London is the surrounding ecosystem: space-focused investors such as Seraphim Space sit alongside the City’s finance and insurance markets, national policymaking, defence customers and a dense base of AI talent.
