SIRO was launched in 2015 as a joint venture between ESB and Vodafone with the aim of delivering the first 100% fibre-to-the-building broadband across regional Ireland and revolutionising the broadband market in Ireland.

Fibre to the Home (FTTH) is an access network method that delivers the highest possible speed of Internet connection by using optical fibre that runs directly into the home, building or office. FTTH is unique, because it removes all the bottlenecks that slow the performance of other types of network. The SIRO Network is built using the ESB’s overhead and underground infrastructure, ensuring a fast, reliable and sustainable network.
SIRO is an open access, wholesale network. This means we are available to authorised broadband providers in the country so you can choose your preferred provider.
There is up to 60% lower energy usage and 80% lower maintenance required for fibre-to-the-building versus copper networks. Plus as a company, we have signed up to the United Nations Global Compact.
Because we’re still building the network, our Gigabit Hub initiative gives people across regional Ireland the opportunity to experience the SIRO 100% fibre network first hand.

When you purchase SIRO from a broadband provider, an engineer will visit your home at a time agreed by you to complete the fibre installation. SIRO will be brought into your home either overhead or underground and into the ESB meter box. An external connector box which houses the SIRO fibre will be positioned close to the ESB meter box.
The engineer will agree with you where to install our internal connector box. Some minor drilling is involved and some cabling depending on where you would like your modem. The engineer will ensure and prove that your home is receiving the fibre speed based on the package purchased.
For SME and Enterprise customers, an engineer will work with the business to determine the entry point. Where applicable the existing communications space will be utilised.
Reliability: SIRO’s 100% fibre-to-the-premise network is delivered using ESB existing infrastructure, with no copper connection at any point in the network. For example, the signal on a copper wire drops massively over just two kilometres, whereas fibre-optic cable over the same distance is extremely reliable.
Gigabit Speed: SIRO’s 100% fibre broadband offers speeds of 1 Gigabit per second, while a copper-based network generally delivers speeds of up to 100 Megabits per second. A 25GB HD movie would take 3 minutes to download on a FTTH 1Gbps connection, but more than 30 minutes on a FTTC 100Mbps connection.
Multiple Devices: Our homes are full of devices as we continue to work remotely – multiple laptops, tablets, consoles and mobiles are usually connected to the internet at once. With SIRO 100% fibre broadband, you can connect as many devices to your broadband as you like and not slow down your connection.
Future Proof: Unlike copper network, fibre-optic cables are extremely resilient to heat, humidity and extreme weather conditions, making this the last broadband connection you’ll ever need. Our Gigabit network is capable of supporting much faster speeds in the future, enabling homes and businesses to cater to evolving technologies and meet future data needs.
SIRO’s footprint already spans across 26 counties and extends to over 515,000 homes and businesses. We now plan to extend our network to cover 154 towns bringing our total coverage to 770,000 premises. While a full list of our new towns is not yet available, we recommend signing up for our monthly updates at siro.ie/register-your-interest to be kept up to date with our rollout plans.
