Yes, SIRO’s network is compliant with all relevant building requirements. We provide an open access enabled network, available for all operators to use. This ensures that additional networks are not required.
ESB is our parent company. However, SIRO is a fully commercial entity, independent from ESB. While we roll out our fibre network the ESB electricity network, we have no responsibility for the ESB connection to your New Development.
SIRO’s objective is to bring our full fibre broadband to every new development. We work with hundreds of developers across Ireland – big and small, private and social and affordable. These include developers such as Glenveagh, Homeland Group, Quintain, Park, O’Flynn Group, the Land Development Agency, housing bodies and local authorities.
SIRO is available in all cities and large towns across the country – over 135 towns and cities in every county in Ireland. We currently have 200,000 active customers Our full fibre network is built to last for the next 50 years. Once we complete our build on a new development, we continue to maintain and upgrade that network as required.

SIRO 100% Fibre Broadband network offers speeds of up to 10 Gigabits per second.
Fibre to the Home (FTTH) is an access network method that delivers superior speeds of internet connection by using optical fibre that runs directly into the home, building or office. The SIRO network is built using the ESB’s overhead and underground infrastructure, ensuring a fast, reliable and sustainable network. Fibre-to-the-Cabinet (FTTC) versus Fibre-to-the-Home (FTTH). In an FTTC connection, copper is used for the last piece of the connection (from tens to hundreds of meters) connecting the telephone exchange cabinet on the street and the router in your house. All the speed-of-light goodness of fibre optics is lost during this last stretch, and that’s why FTTC delivers speeds of no more that 100Mbps. On the other hand, SIRO FTTH network connects 100% fibre optic cables all the way to your home, delivering speeds up to 2000Mbps (2Gb). Fibre is faster, more reliable, and superior to copper in many ways, as it removes all the bottlenecks commonly seen in a copper network. You can connect as many devices as you like, play HD games, watch Netflix and download movies without slowing down your connection.
