Network operator nexfibre, which shares some parentage with ISP partners Virgin Media (O2) and giffgaff, has published their latest quarterly Q3 2025 build update and confirmed that their new 10Gbps capable Fibre-to-the-Premises (FTTP) broadband network now covers 2.44 million UK premises. But future deployments beyond 2025 remain uncertain.

Just to recap. Back in 2022 Telefónica, Liberty Global and InfraVia Capital Partners setup nexfibre as a new £4.5bn joint venture (here), which aimed to deploy an open access (wholesale) full fibre network to reach “up to” 7m UK homes (starting with 5m by 2026) in areas NOT served by Virgin Media’s own network of 16m+ premises. The funding reflects £3.3bn of fully underwritten financing and up to £1.4bn in equity commitments.

NOTE: Virgin Media and giffgaff are currently the only big retail providers on nexfibre’s network.

However, as existing readers will already know, nexfibre’s roll-out plan recently suffered a significant blow after Telefonica launched a Strategic Review of their global business (here and here). The decision has since resulted in nexfibre scaling back their planned roll-out – now aiming to reach just 2.5m premises in 2025 (down from c.3m).

The latest Q3 2025 build update from nexfibre continues to reflect this change and confirms that their full fibre network has now reached 2.44 million premises as ready for service (up from 2.3m in Q2). In addition, this week’s publication of Telefónica’s Strategic Plan for the future (here) suggests that we may soon get a better idea of what approach nexfibre will be taking for 2026 and beyond.

Rajiv Datta, CEO of nexfibre, said:

“nexfibre continues to make strides in expanding full-fibre broadband to communities across the UK that have historically been underserved. With our network now reaching over 2.4 million premises, we’re proud to be one of the largest alternative fibre providers in the country.

Our optimised rollout strategy is progressing as planned, powered by the dedication and agility of our exceptional team and trusted partners. Together, we’re building a technologically-advanced, XGS-PON-only network designed to meet the needs of future generations.

With the backing of committed investors and robust financial support, we remain focused on developing a wholesale fibre platform that will be instrumental in driving market consolidation and unlocking the full potential of the UK’s digital infrastructure.”
