The rollout of the NBI™ Network is divided up into 227 Deployment Areas, with multiple Deployment Areas in each county.
So, while you might be in one deployment area, your Neighbour might in another.

Each deployment area spans about 25km.

Together they will provide high-speed fibre broadband to over 544 thousand premises in Ireland, no matter how remote or rural. The rollout of the fibre network is designed to reach as many people in all counties as fairly as possible.
With the route as efficient and effective as we can make it.

Each Deployment Area connects to at least one of 33 Regional Exchanges with the network joining them together in rings.
We build the NBI™ Network like this to ensure reliability and resilience against network outages.

So, in the event of one Deployment Area being disrupted, the rest of the NBI™ network will continue to perform as it should. Keeping as many people as possible connected, night and day. Check your premises HERE

Phase 1: Surveying – Physical surveys of townlands is required to examine the existing pole and duct network for inclusion in the design,

Phase 2: Design – NBI’s Detailed Design process confirms infrastructure, power & footprint required, drawings, openeir works, Local Authority requirements, and revised cost analysis. The NBP Unit in DECC reviews & approves NBI designs including any cost variance from original high-level estimates.

Phase 3: Build – After the designs have been approved, pre-works then main works start on the ground: readying existing infrastructure (openeir), upgrading & adding poles and ducts, laying fibre, preparing backhaul facilities, fulfilling Local Authority requirements, tree trimming.

Phase 4: Build Complete – NBI “pass” the premises with fibre. Consumer orders can be submitted to Retail Service Providers

Phase 5: Consumer Orders received – Retail Service Providers will receive orders from customers

Phase 6: Consumers Connected – Consumers are connected to High Speed Fibre Broadband by Retail Service Providers.

All dates provided are estimated based on our current view, but are likely to change in the future.

For example, your premises may be re-assigned to another Deployment Area with a different rollout timescale. This Deployment Area reassignment can happen at any stage up until build is complete in the area. Other unforeseen changes outside the control of NBI can also impact the estimated date over the course of the rollout.

Because of the scale of this project, NBI high-speed fibre broadband will become available in different areas at different times. You can check your premises HERE to see if your address is in the intervention area.

We started surveying premises in the Intervention Area in Jan 2020. When surveys are completed in each deployment area, this will enable low level designs for fibre rollout there. First premises in Carrigaline was successfully connected by National Broadband Ireland to new high-speed fibre network achieving minimum speeds of 500Mbps in January 2021.

The NBI™ Network rollout for the National Broadband Plan is divided up into 227 ‘Deployment Areas’ – known as DAs – up and down the country, taking in every county. These are typically an area of approximately 25km in radius and in total, all 227 deployment areas will cover 96% of Ireland’s landmass. Find out more HERE

We will have completed the NBI™ Network build within 5-7 years. NBI are currently in discussions with the Government around expediting the project programme. We will continue to add to and upgrade the network, and connect new homes or premises built in the roll-out area, over the next 25 years.

Key information on the rollout and progress made to date can be found on our rollout page at /rollout-plan/ but for detailed information about the progress in your area you can sign up for updates at /eoi/

The rollout of the NBI™ Network is divided up into 227 Deployment Areas, with multiple Deployment Areas in each county.

NBI’s priority is to keep operations on track, despite the challenging environment caused by COVID-19. The progress made to-date and the recovery strategies planned, give confidence that future milestones will be achieved.

NBI is exploring the feasibility of accelerating aspects of the planned roll-out to establish the possibility of bringing forward premises which are currently scheduled in years six and seven of the plan to an earlier date. These discussions are ongoing.

We have commenced works in 26 counties across the country with the first homes getting connected. People can check when they can various phases are happening in their area by visiting

The date range on our network map is the date range that NBI are working towards. NBI remain committed to rolling out the National Broadband Plan ahead of time, and our regular discussions with the DEEC include exploring how that might be expedited quicker.

If your premises isn’t included in the roll out of the National Broadband Plan, but you cannot receive internet speeds of 30Mb or more from any commercial broadband provider, the following steps should be taken;

  1. Contact your broadband service provider to investigate the issue and to determine the reason why your broadband speeds are slow or that the service cannot be provided. 
  2. Following the service provider investigation, if you are unable to receive over 30Mbps from any broadband service provider, then you can apply to the Department of the Environment, Climate and Communications (DECC) who will undertake an investigation on your behalf. 
  3. The investigation will determine if high-speed broadband could be provided to you by a commercial broadband provider in a timely manner or and if this is not the case, then DECC will determine if your premises could be included in the National Broadband Plan fibre rollout.

Contact for further details

If your premises has not yet been built, it will not be currently included in the Intervention Area. However, NBI is committed to deliver high-speed fibre broadband to all new premises built within the Intervention Area. If you have reviewed the High-Speed broadband map ( and believe your new build house qualifies to be included within the Intervention Area, please email the Department of the Environment, Climate and Communications at

NBI is responsible for rolling out the Government’s National Broadband Plan, which is a state-subsidised project to provide high-speed fibre broadband to all parts of the country where commercial operators do not currently offer high-speed connectivity or have indicated that they do not have plans to do so. As a private company, Eir operates a purely commercial network that is not part of the National Broadband Plan and does not receive Government subsidy.

To check if your premises is covered under the EIR program, we suggest getting in touch with EIR. Their broadband maps might be a good place to start and can be found at

If you are in the Intervention (Rollout) area you will get service. There may be timing gaps between connecting roads between different roll out deployment areas; however everyone will get service as part of our 100% commitment.

Getting Connected

Yes! NBI and Internet Service Providers will be conducting advertising in all areas as the NBI™ Network is rolled out so potential customers will be aware of when services are available in their area. Another way to keep up to date is to sign up for updates on the NBI website. Simply log onto and enter your email address and Eircode for this.

No. NBI is a wholesaler. This means that we do not sell directly to the public. To connect to a plan you need to speak to your service provider.

DECC carried out a mapping exercise for the Intervention Area and collated data from commercial internet service providers who reported that they can provide download speeds of 30MB or higher in your area. This Comreg link may assist: or else other broadband cost comparative websites may list other local providers in your area. If, for some reason a service of 30MB download is not available to you, you can request to be included in the Intervention Area by emailing

Once high-speed fibre broadband is available in your area, you can check the list of all broadband service providers available on the NBI website. here.
You can also sign up to a regular newsletter HERE that will notify you when we are working in your area and who you can purchase services from. Once you’ve chosen a broadband service provider, you will place your order directly with them.
Note, NBI does not sell broadband services to customers. We operate a wholesale service where we partner with broadband service providers throughout Ireland who in turn deliver a service to your door.

In some cases, customers will require additional poles to be erected on their property. This is to facilitate delivery of fibre optic cables into your home, farm or business. If there are existing poles already on, or feeding your property, then these will be reused with no requirements for new poles.

In the vast majority of cases, NBI will reuse pre-existing poles and ducting meaning there will be no need for any grounds work when installing fibre broadband. In a small number of cases where there is a blockage within an existing duct or in the event a customer requested duct where no ducting exists, this may necessitate civil works on the customer’s premises.

Installation of new underground ducting on a home or business premises information can be found on – installation page HERE

Fibre Facts

Fibre broadband is a type of high-speed broadband. It uses fibre optic cables from your local broadband exchange right to your home or business. These particular cables are far more efficient at transferring data than standard copper cables or wireless services.
Fibre Broadband gives you the power to do all the things you need to do on the internet, but faster and more reliably. For example, downloading large files, streaming your favorite films in ultra-high definition, online calls/meetings and backing up your work and personal databases on cloud software.

NBI fibre broadband uses a network of fibre optic cables to deliver high-speed data over long distances, the length and breadth of Ireland. This data travels down the cables at the speed of light, right into your home or business.

Unlike standard broadband, which relies on older copper based network technologies, the NBI fibre broadband network consists of a full fibre solution that supplies right to your door, which ensures reliability of speed and service.

Broadband download speeds ranging from 500Mb up to 1Gbp will be offered from the outset. You will choose your speed from a broadband service provider and not NBI, who are the new fibre network wholesaler. Upload speeds will range from 50Mb for the 500Mb product and 100Mb for 1Gb product. Once an area has been connected and is ‘live’ the NBI website will have a link to all the retail service providers offering broadband/packages.

NBI do not sell broadband directly to homes or businesses. Instead, we partner with a range of trusted service providers who will provide you with the fast broadband products and customer service you need. These services and ‘bundle packages’ must be comparable with those currently being offered in rural areas.

Fibre is future proofed. We are building a network to support the needs of customers in rural Ireland for generations to come. Wireless networks may be able to support some current needs but will not support the forecasted growth in internet usage. It should also be noted that we are building an open wholesale network that can be utilised by any retail service provider. This enables both local and large international broadband providers to deliver a full range of services.

You’ll need to speak to your preferred service provider about the choice of plans, that best suit your needs.

An ISP is an Internet Service Provider and an RSP is an Retail Service Provider. They are the companies who sell broadband and these are usually bundled with TV, mobile and home phone. NBI will partner with trusted Service Providers to deliver fibre broadband services to people in the Intervention Area.

Download & Upload speeds will vary depending on the packages offered by the Retail Service Provider but all will offer NBI’s minimum service.

Broadband Connection Points

Broadband Connection Points (BCPs) are places such as community halls, libraries, sports facilities, enterprise hubs, tourist locations and other public spaces in each county where everyone can enjoy access to high-speed broadband. These will include a number of connections to islands such as Inis Mein and Cape Clear. We can deliver this free broadband access service to the public thanks to funding from the Department of Rural and Community Development (DRCD). Locations have been identified by the county councils with support from the broadband officers and other local community groups. Locations are subject to change. Click here for more information on the BCPs

Locations have been identified by the county councils with support from the broadband officers and other local community groups.

Each BCP will have up to 150Mb high-speed broadband, with indoor and outdoor Wi-Fi access for the local community. This will enable people living in the area, visitors or tourists to go to their local BCP for any kind of personal or business use from work to study or social activity.
