CityFibre Top 1 Million Customers on UK Full Fibre Broadband Network

The UK’s biggest alternative 10Gbps capable Fibre-to-the-Premises (FTTP) broadband operator, CityFibre, has this morning revealed that over one million households and businesses are now making the most of their national network (up from 848,000 at the end of 2025 – here). A good chunk of their recent growth has been driven by last year’s addition of Sky Broadband to the platform.

The company’s full fibre (FTTP – XGS-PON) network currently covers over 4.7 million UK premises (4.5m Ready for Service) and they still aspire to reach 8 million in the future. In addition, the operator also holds nine Project Gigabit contracts, although these were significantly scaled-back last week (here).

Alongside its full fibre broadband services, CityFibre is also a provider of Critical National Infrastructure (CNI) to mobile operators, enterprises and local authorities, which now connects almost 16,000 sites including schools, hospitals and GP surgeries across the UK.

The operator has today also announced its new digital literacy initiative, with plans to reach over one million primary-aged learners with an “expertly designed toolkit that will build confidence, curiosity and foundational digital skills“. Working in partnership with education experts, 8billionideas, the initiative will rollout ‘The Tech Toolkit’, a creative, classroom ready resource, to around 5,000 schools each year and one million primary school children by 2030.

Simon Holden, CEO of CityFibre, said:

“We have built a nationwide, full fibre network to be proud of and, today, CityFibre is trusted by millions to power their digital lives. The UK shifted up a gear with the arrival of the altnets and CityFibre continues to challenge the incumbents and deliver the benefits of competition to households, businesses and partners right across the country.”

Liz Lloyd, UK Telecoms Minister, said:

“This milestone shows the difference government’s pro-investment environment is making, helping bring fast, reliable broadband to homes and businesses in some of the UK’s hardest-to-reach communities.

Our investment in broadband infrastructure, including through Project Gigabit, is helping companies like CityFibre reach more communities, faster. We’ll continue to remove barriers to rollout and back the investment needed to deliver the digital infrastructure people rely on every day — whether that’s working, learning, running a business or staying connected with friends and family.”

Sadly today’s announcement didn’t include any updated details on their latest premises passed (coverage) figures, which would have been good to know.
