Nexfibre

What Nexfibre does

Nexfibre Networks Limited is a UK wholesale-only full-fibre (FTTH) broadband network operator incorporated in July 2022 as a joint venture between InfraVia Capital Partners, Liberty Global and Telefónica, with £4.5 billion of equity and debt financing committed at formation. The company builds and operates passive optical network infrastructure that delivers high-speed internet to homes and businesses, selling wholesale capacity exclusively to internet service providers (ISPs) and B2B resellers. Virgin Media O2 is the anchor tenant and build partner, providing managed services including construction and committing wholesale traffic on 4.6 million premises; giffgaff became the second wholesale ISP customer on the network in September 2025.

The network is built exclusively on XGS-PON architecture, capable of symmetrical upload and download speeds of up to 10 Gbps — Nexfibre is the only fibre provider of significant scale deploying this technology exclusively. The infrastructure uses a passive optical network design with a weighted average 50m drop-cable connection to premises and is delivered with a high-build-density model targeting 70–75% postcode coverage within deployment areas (averaging 80% in conjunction with VMO2). An in-house audit team personally inspects every build as part of service acceptance, and the company is developing its own API to streamline ISP integration.

The business model generates recurring revenue through wholesale network access fees charged to ISPs per premises served. Nexfibre had passed 2.6 million premises and reached ready-for-service status as of 31 December 2025, growing from 500,000 premises in September 2023 — the fastest build pace of any UK fibre operator. The company is investing toward 5 million premises by 2026, and the £2 billion acquisition of Substantial Group (Netomnia) announced in February 2026 is expected to bring the combined platform to approximately 8 million premises by end of 2027, with a combined nexfibre/VMO2 footprint of up to 20 million premises nationally.

Revenue model

1. Wholesale Network Access Fees: Nexfibre generates revenue by charging ISPs wholesale fees for access to its full-fibre network. Virgin Media O2 is the anchor tenant paying wholesale fibre access fees, and additional ISPs (such as giffgaff) also pay for network access. The company also earns fees from VMO2 on customers within overlapping Virgin Media O2 HFC homes.
2. Wholesale Traffic Commitment Fees: Virgin Media O2 commits wholesale traffic across 4.6 million premises in exchange for cash and a stake in nexfibre, generating ongoing wholesale access fees as services become available on upgraded fibre premises.

Core offering

Nexfibre is a wholesale-only full-fibre (FTTH) broadband network provider deploying XGS-PON architecture capable of symmetrical speeds up to 10 Gbps. The company sells wholesale network access to ISPs and B2B resellers (anchor tenant Virgin Media O2 and second wholesale customer giffgaff) rather than selling broadband directly to consumers. It had passed more than 2.6 million premises by December 2025, with a target of 5 million by 2026 and approximately 8 million by end of 2027 following the Netomnia/Substantial Group acquisition.

Product overview

nexfibre is a wholesale-only, next-generation full-fibre broadband network platform that deploys XGS-PON architecture capable of symmetrical speeds up to 10 Gbps. The core offering is the nexfibre Full Fibre Network, which serves as infrastructure for retail internet service providers. Virgin Media O2 operates as the anchor wholesale tenant providing services up to 2Gbps, while giffgaff broadband launched on the network in September 2025 as a second wholesale customer. Following the February 2026 acquisition of Substantial Group (Netomnia), the combined platform will reach approximately 8 million premises by end of 2027, creating a national-scale challenger to BT Openreach alongside Virgin Media O2's growing footprint.

Partnerships

Four partnerships are on record, tiered supporting and core.

• giffgaffsupportingChannel Partner/ Reseller/ Distributor · 30 April 2025giffgaff launched full fibre broadband on nexfibre's network as the second wholesale customer. Developed with over 500 trialists, giffgaff broadband offers three simple monthly rolling plans from £34 with speeds from 200Mbps to 900Mbps, including One Touch Switch and Amazon's eero technology for whole-home Wi-Fi. giffgaff aims to expand across nexfibre's network and the upgraded VMO2 footprint.
• UK YouthsupportingStrategic or Co-development Partner · 11 September 2024nexfibre partnered with UK Youth, a leading charity reaching more than 4 million young people across the UK, to tackle digital poverty. Nexfibre offers up to 1,000 youth centres full-fibre broadband (up to 2Gbps) free of charge for 2 years, delivered via Virgin Media O2. The initiative supports nearly 570,000 young people who lack access to learning devices and reliable internet. Following the Netomnia acquisition announcement, an additional 456 youth centres across the country became eligible for the offer.
• PIA Coalition (AllPoints Fibre, Community Fibre, Gigaclear, Netomnia and Brsk)supportingStrategic or Co-development Partner · 2 August 2024Nexfibre initiated and co-founded the Physical Infrastructure Access (PIA) Coalition together with AllPoints Fibre, Community Fibre, Gigaclear, and newly-merged Netomnia and Brsk. The coalition represents over 5 million premises RFS and calls on Ofcom to ensure a level playing field for PIA access to Openreach's ducts and poles. Economic analysis (by SPC Network) identified material pricing disparities where altnets pay significantly more to access infrastructure compared to Openreach's internal costs.
• Virgin Media O2coreStrategic or Co-development PartnerVirgin Media O2 is nexfibre's anchor wholesale tenant and build partner. VMO2 provides broadband services up to 2Gbps across the nexfibre network and provides full suite of managed services including construction. As part of the Netomnia deal, VMO2 receives £1.1 billion in cash and a 15% indirect stake in nexfibre in exchange for wholesale traffic commitments on 4.6 million premises. VMO2 acquires YouFibre and Brsk retail brands for £150 million. Together, nexfibre and VMO2 intend to wholesale their combined networks (reaching up to 20-23 million premises) to other ISPs.

Others

• Virgin Media O2: Nexfibre's anchor wholesale tenant and build partner, co-owned by Liberty Global and Telefónica. While both companies operate complementary fibre networks and wholesale together to ISPs, VMO2 is Nexfibre's largest customer.
• Sky Broadband: Major UK ISP retailing broadband, currently primarily over BT Openreach infrastructure. Potential future wholesale ISP customer for Nexfibre's network as it expands beyond VMO2 and giffgaff.

Direct peers

• Community Fibre: London-focused altnet deploying FTTH wholesale infrastructure, one of the UK's largest altnets. Direct competitor in wholesale fibre to ISPs and co-member of PIA Coalition with Nexfibre.
• Hyperoptic: UK altnet deploying full-fibre to residential and business customers, primarily in urban MDU and suburban areas. Direct competitor in wholesale and retail full-fibre broadband markets.
• Gigaclear: UK rural-focused altnet delivering FTTH broadband to underserved communities. Direct competitor targeting ISP wholesale partnerships; co-member of PIA Coalition with Nexfibre.
• Netomnia: UK's fourth-largest FTTH altnet (now being acquired by Nexfibre). Once integrated, will form part of the combined wholesale platform — also a wholesale competitor in the interim to completion.
• CityFibre: UK's largest alternative fibre platform (altnet) deploying FTTH wholesale infrastructure to ISPs. Direct competitor to Nexfibre in the wholesale full-fibre market, also targeting multi-ISP partnerships.
• AllPoints Fibre: UK altnet group providing full-fibre wholesale and retail broadband services. Direct competitor in the UK altnet landscape and co-member of PIA Coalition with Nexfibre.

Regional players

• Deutsche Glasfaser: Germany's largest alternative FTTH wholesale operator, comparable European altnet with similar XGS-PON deployment and wholesale-to-ISP business model. Relevant international comp for UK fibre infrastructure investing.

Broad incumbents

• BT Openreach: Dominant UK wholesale fibre and copper infrastructure provider, serving all major ISPs. Nexfibre's primary strategic target as a national-scale wholesale challenger to Openreach's monopolistic position.
