Revenue model

1. Wholesale Network Access: SIRO operates as a wholesale open-access fibre network provider, generating revenue by providing network access to retail internet service providers (ISPs) who then serve residential and business end customers. SIRO does not sell directly to consumers but enables multiple retailers to offer services over its fibre infrastructure.
2. Developer/New Development Services: SIRO works with property developers to pre-install fibre broadband infrastructure in new home developments, integrating connectivity into new construction projects.

Core offering

SIRO is a wholesale open-access fibre-to-the-home (FTTH) broadband network operator that builds and operates a 100% fibre network using XGS-PON technology on ESB electricity infrastructure. The company sells wholesale network access to retail ISPs who serve end customers, and directly engages property developers for fibre pre-installation in new home developments.

Product overview

SIRO Ireland is a wholesale open-access 100% fibre-to-the-home (FTTH) broadband network operator jointly owned by ESB and Vodafone, founded in 2015. The company's product portfolio centres on its full-fibre network infrastructure, which delivers broadband speeds up to 5Gbps (with capacity for up to 25Gbps) to over 700,000 homes and businesses across more than 150 Irish towns and cities in every county. SIRO operates exclusively as a wholesale provider — selling network access to retail ISP partners rather than directly to consumers — and its offering spans three core segments: residential broadband (up to 2Gbps for consumers), business broadband (small, medium, and large enterprise connectivity), and wholesale access for retail partners. Supplementary offerings include the SIRO-Vodafone GigabitHub Initiative for digital enterprise hubs, and pre-connection services for new home developers via the SIRO for Home Developers programme. The network is built on ESB electrical infrastructure using fibre-to-the-building architecture with no copper at any point.

Direct peers

• Open Fiber: Italy's wholesale-only FTTH operator, directly comparable to SIRO as a national open-access fibre network selling capacity to retail ISPs. Previous co-winner of the same European fibre award SIRO won in 2025.
• CityFibre: UK wholesale FTTH network operator with an open-access model serving multiple ISPs (Vodafone, TalkTalk, etc.). Closest functional analogue to SIRO's wholesale-only architecture in a comparable market.
• Community Fibre: UK FTTH provider building full-fibre networks primarily in London and serving both retail and wholesale customers. Comparable XGS-PON deployment and multi-gigabit positioning to SIRO.
• Hyperoptic: UK-based full-fibre broadband operator offering multi-gigabit services to residential and business customers, with a mix of direct and partner sales — comparable technology and customer segments to SIRO.
• Deutsche Glasfaser: Germany's largest alternative FTTH operator, deploying fibre in rural and suburban areas via partnerships with municipalities and utilities. Comparable in scale and open-access deployment model.
• National Broadband Ireland: Irish state-subsidised wholesale FTTH operator rolling out fibre in Ireland's intervention areas. Direct competitor in the same Irish market, complementing SIRO in non-overlapping regions.

Broad incumbents

• Eir (eircom): Ireland's incumbent telecoms operator with legacy copper/fibre network and own retail ISP. Competes with SIRO as both infrastructure rival and a potential wholesale/retail channel overlap.
• Virgin Media Ireland: Irish quad-play operator and SIRO's largest ISP partner; transitioning from DOCSIS cable to XGS-PON fibre. Acts as both customer and increasingly as direct fibre competitor.

Others

• Vodafone Ireland: SIRO's JV parent and telecom operator; partners with SIRO on the Gigabit Hub Initiative while also offering competing broadband services. Strategic alignment makes it both shareholder and ecosystem participant.
• ESB Networks: SIRO's JV parent and infrastructure enabler; ESB's electricity network is the physical foundation of SIRO's FTTH rollout. Comparable utility-telecom convergence model enables SIRO's cost advantage.
