SIRO broadband explained
SIRO is rolling out across Ireland. Learn about what SIRO is and how it brings superfast, reliable broadband to homes and businesses.
What is SIRO broadband?
SIRO is a joint venture between ESB and Vodafone that uses the existing electricity network to provide 100% fibre broadband in Ireland.
This type of Fibre-to-the-Home (FTTH) broadband is often referred to simply as full fibre.
SIRO at a glance
How does SIRO broadband work?
SIRO uses fibre optic cables that run alongside ESB’s electricity infrastructure and connect directly to your home.
Because the connection is fibre end-to-end, you avoid the speed drops and signal loss that can happen with older copper telephone lines.
SIRO full fibre vs regular fibre (FTTC/part-fibre)
| Feature | SIRO (FTTH full fibre) | Regular fibre (FTTC / part-fibre) | |
|---|---|---|---|
| How it’s delivered | Fibre straight to your home (no copper) | Fibre to the cabinet, then copper to your home | |
| Typical speeds | 500Mb–2Gb plans | Up to 1Gb, often lower at distance | |
| Reliability & latency | Very stable; low latency for streaming, gaming and calls | Varies by line quality, distance from cabinet | |
| Consistency at peak times | Strong; single fibre line to the home | Slow when many homes share the same cabinet | |
| Best for | Busy homes, remote workers, gamers | General browsing/streaming where full fibre isn’t available |

How fast is SIRO broadband?
Most SIRO broadband packages offer download speeds from 500Mb up to 2,000Mb (2Gb), depending on the provider.
The network is built to support even faster services as it expands.
Typical SIRO speeds
Compare typical speeds for each type of internet user. Actual speeds depend on your chosen SIRO provider, plan, and in-home setup (router, wiring, Wi-Fi).
| Plan speed (up to) | Great for | |
|---|---|---|
| 500Mb | Multiple HD streams, video calls, smart home devices | |
| 1Gb | 4K streaming, cloud backups, heavy WFH users | |
| 2Gb | Large households, gamers, creators, fastest downloads |
Is SIRO broadband any good?
Yes, SIRO broadband is widely regarded as one of the fastest and most reliable broadband networks in Ireland.
Because it’s built on a 100% fibre-to-the-home (FTTH) network, your connection doesn’t depend on old copper lines or shared street cabinets.
This means fewer slowdowns at peak times and consistently high speeds, even with multiple devices online.
Who provides SIRO broadband in Ireland?
You can’t buy directly from SIRO as it’s a wholesale-only network. Instead, you sign up through one of the broadband providers that use the SIRO network.

SIRO broadband FAQs
Who owns SIRO broadband?
SIRO is a joint venture between ESB (Electricity Supply Board) and Vodafone Ireland. The network uses ESB’s existing electricity infrastructure to deliver full fibre broadband to homes and businesses across the country. SIRO provides the network, while broadband plans are sold through authorised retail partners such as Vodafone, Digiweb, Sky, and Pure Telecom.
Does eir use the SIRO network?
No, eir operates its own fibre network, known as Open Eir. This is a separate full-fibre network from SIRO, although both offer similar speeds and technology. If SIRO isn’t available in your area, you may still be able to get a full-fibre connection through the Open Eir or NBI networks instead.
How do I check if SIRO broadband is available where I live?
You can check availability directly on the SIRO website, or by using Switcher.ie’s broadband checker.
Just enter your Eircode, and we’ll show you which SIRO providers and speeds are available in your area, along with the latest deals and prices.
What if SIRO broadband isn’t available in my area?
If SIRO hasn’t reached your area yet, you may still have access to other full-fibre networks such as Open Eir or National Broadband Ireland (NBI).
If full fibre isn’t yet live where you live, you can try part-fibre, cable (Virgin Media), or mobile and satellite broadband.
