CityFibre is the UK’s largest independent full fibre infrastructure platform, providing carrier-neutral digital infrastructure to its wholesale customers and enabling ultra-fast, reliable and futureproof broadband, Ethernet and 5G services to homes and businesses as well as schools, hospitals and GP surgeries. CityFibre is rolling out its full fibre network to reach at least a third of the UK market: more than 8 million premises.
As the UK’s most intelligent fibre network, CityFibre is trusted by major Internet Service Providers and mobile operators including TalkTalk, Three, Vodafone and Zen as well as a new generation of smaller regional ISPs dedicated to delivering full fibre broadband. In August 2024, Sky and CityFibre announced a long-term partnership that will see Sky launch broadband services on the CityFibre network.
CityFibre is based in London and is owned by funds managed by Antin Infrastructure Partners, Goldman Sachs Asset Management, Mubadala Investment Company, Interogo Holding and Newlight Partners.
