What is SIRO?

SIRO is a joint venture between Vodafone and the ESB. The aim of the project is to develop an extensive, high-speed, fibre-to-the-home broadband network around Ireland. Fibre-to-the-home is often called pure fibre as it doesn't rely on old telephone copper wires for any of the network. 

How fast is SIRO?

Currently the fastest broadband speeds top out at around 500Mbps, but many households achieve far lower speeds. However SIRO will be able to provide speeds of up to 1,000Mbps or 1Gbps, which is significantly faster.

As Ireland’s largest fibre-to-the-home operator, SIRO promises to deliver speed, reliability and gold standard broadband to homes and businesses across Ireland. 

How could it benefit me?

As we already explored in our guide to fibre broadband, fibre-powered broadband is more stable than ADSL connections and does not suffer from drops in speed as a result of multiple users. 1Gbps speeds mean a whole world of possibilities for consumers both at home and at work. Read on to see how you could benefit.

At home:

A superfast and reliable connection means that working and studying from home is now more possible than ever. The stability that a pure fibre connection offers means that you and your household can use many devices without the loss of much speed making it possible for everyone to benefit at the same time.

This is great news for households where families are often put head-to-head fighting over the bandwidth – now you can stream a movie in one room, play X-box in another and download large files all at the same time.  

At work:

If there’s one place that fast and reliable internet is essential it’s the workplace. In a nutshell, a 1Gbps connection, in addition to the benefits mentioned above, offers business a more seamless collaborative experience.

As SIRO itself puts it; "All over Ireland, sole traders, SMEs, start-ups and regional businesses can now collaborate, expand and grow without facing technological barriers."

To put these speeds into context; a 1Gbps connection means a fast and reliable cloud service, crystal clear video conferencing and lightning-quick file sharing capabilities among other things. SIRO is aiming to transform regional Ireland by creating attractive locations for business investment.   

Is it available to me?

SIRO-powered broadband is available to almost 500,000 homes and businesses in Ireland, in regions such as Cavan, Dundalk, Westport, Castlebar, Sligo, Carrigaline, Tralee, Navan, Letterkenny, Wexford and parts of Dublin.

SIRO is a wholesale broadband provider which is sold to households by retailers such as Vodafone, Sky and Digiweb, as well as regional providers such as Westnet, Carnsore, Rocket Broadband, Airwave and Kerry Broadband.

What kind of prices am I looking at?

Each provider's prices vary. Generally the entry-level price for SIRO with a top speed of 150Mbps starts at around €20 to €25 per month. However, if you want to benefit from a full 1Gbps connection, you are generally looking at around €50-€80 per month.
