What Brsk does

Brsk was a UK-based alt-net full fibre broadband provider founded in 2020, delivering residential and business broadband services primarily in Manchester and Leeds & Bradford. The company operated as part of Substantial Group alongside Netomnia, the underlying fibre network platform covering approximately 3 million UK premises, and YouFibre, a sibling retail broadband brand. Brsk's service quality was independently validated by Opensignal, which ranked it among the top performers in fixed broadband metrics for its operating regions. The company served individual households requiring high-speed internet for streaming, gaming, and remote work, as well as small and medium businesses needing reliable commercial connectivity.

Brsk's revenue model was built on recurring monthly subscription fees for residential and business broadband packages, sold directly to consumers through its website channel. The company operated a direct-to-consumer go-to-market motion with no named enterprise anchor customers and no disclosed enterprise segment. Network infrastructure was shared with the broader Substantial Group, providing cost-per-bit advantages versus resellers and copper-based competitors.

In February 2026, Brsk's parent Substantial Group was acquired by nexfibre, a joint venture between Telefonica SA and Liberty Global Corp., for £2 billion, marking the first major consolidation in the UK alt-net broadband market. Virgin Media O2 subsequently acquired the Brsk and YouFibre retail brands for £150 million, positioning it as the UK's second-largest fibre operator after BT's Openreach. Following this transaction, the Brsk brand was officially merged into YouFibre, unifying the two retail brands under a single broadband provider to enable greater investment in network, customer service, and future products. The transaction unlocked £3.5 billion in committed fibre network expansion investment, with InfraVia Capital Partners, Liberty Global, and Telefonica contributing £1 billion in new funding.

Direct peers

• YouFibre: YouFibre is Brsk's sister brand within Substantial Group, offering the same full-fiber residential broadband product in adjacent UK regions. The two brands have been merged into one entity following the nexfibre/VMO2 acquisition, making YouFibre the most direct functional peer.
• Netomnia: Netomnia is the wholesale fiber network platform within Substantial Group that Brsk's services run over. As the underlying infrastructure operator covering ~3 million homes, Netomnia is directly comparable as an alt-net fiber builder and the asset Brsk most directly sits on top of.
• CityFibre: CityFibre is the UK's largest independent full-fiber platform, building wholesale FTTP in many of the same towns and cities Brsk operates in. It is the closest direct competitor to Brsk/Netomnia in the UK alt-net segment and shares the same wholesale-plus-retail business model.
• Community Fibre: Community Fibre is a UK alt-net focused on full-fiber broadband, primarily in London. It targets the same residential and small business customer segments as Brsk with a similar gigabit-capable FTTP proposition and subscription pricing model.
• Hyperoptic: Hyperoptic is a UK alt-net ISP deploying full-fiber broadband to residential and business customers in urban areas. It directly competes with Brsk on speed tiers, customer segments, and subscription pricing in overlapping UK city footprints.
• Gigaclear: Gigaclear is a UK rural-focused alt-net building full-fiber networks to underserved communities. It pursues a similar alt-net FTTP proposition to Brsk, albeit with a more rural geographic focus, making it a comparable business-model peer.
• Trooli: Trooli is a UK alt-net building full-fiber networks in the South East and Kent. It targets residential and business customers with a similar subscription broadband model to Brsk, making it a comparable regional alt-net peer.

Broad incumbents

• Virgin Media O2: Virgin Media O2 is now the owner of the Brsk/YouFibre retail brands and operates a national cable and fiber broadband network. It is the broader incumbent that has absorbed Brsk and is directly comparable as a UK quad-play broadband provider.
• BT (Openreach): BT, through its Openreach division, operates the UK's largest fixed-line network and is the dominant wholesale fiber access provider. As the largest incumbent and Brsk's primary wholesale access competitor, BT is the canonical broad-incumbent peer for any UK alt-net.
• Sky Broadband: Sky Broadband is one of the UK's largest retail ISPs, leveraging Openreach's network to sell residential broadband subscriptions. It competes with Brsk for residential subscribers across the UK and is a broad-incumbent reference point for go-to-market scale.
