Best NBI broadband provider in Ireland

Once the NBI map says Passed, the decision is not “which broadband”. It is “which bill”. Every retailer on this page sells the exact same thing: National Broadband Ireland’s fibre to your wall, the same white ONT box, the same NBI engineer doing the drop, the same 500/50, 1000/100 or 2000/200 profile. What changes is the intro price, what you pay from month 13, the activation fee, the April rise and who answers the phone.

Our pick is Vodafone — 500 Mb at €25 for six months, then €40 on 24 months, and €40 is the standing price, not a teaser. Pure Telecom is the fairest 12-month contract (€35 → €50, no built-in hike). Sky has the cheapest two-year bill if you take the 24-month plan at a flat €35, but lands on €67.50 afterwards. Digiweb is the NBI specialist, and its HyperPulse 1000 at €44.95 is better value than its own 500. Eir sells NBI too, with the dearest thereafter on the glass. Imagine is the rolling, no-contract way in.

We rank by our editorial score (contract fairness, year-two cost, service, reliability) — not by who is cheapest in month one. The 24-month cost tables below let you overrule us with a calculator. If you still need the network explained, read NBI explained; if the map does not say Passed yet, read when is NBI coming instead. This page is for the day the pole is live.

Who actually sells NBI broadband?

NBI does not sell to homes. Its “Who can I buy from?” page lists 58 retail service providers in August 2026 — far more than the five or six names most people recognise. The big consumer brands on that list are Digiweb, Eir, Imagine, Pure Telecom, Sky, Three, Virgin Media and Vodafone. The rest are regional and wireless-heritage operators: Westnet, Airwire, Viatel, Magnet, Blacknight, Kerry Broadband, Net1, Rural Wifi, Regional Broadband, Fastcom, Premier Broadband, Tipp Broadband, Carnsore Broadband, Clare WiFi Networks and other local ISPs, plus business-only names like IMS, Elio and eir Business.

We rank the six retailers whose NBI plans we track and can stand over. Virgin Media became an NBI retailer in June 2024 but its public tiles are still built around its own cable footprint — ask for an NBI quote. Three is on the list but sells 5G home, not NBI fibre, to consumers. The regional ISPs are often excellent on support, but their tariffs change without notice and we will not print a price we cannot verify.

What is identical on every NBI retailer

Sales pages dress this up, so here is the plain list. On NBI these things do not change with the logo:

• The fibre. It is NBI’s glass from the pole (or duct) to an optical box on your wall. No retailer has a “better” NBI line.
• The ONT. A small NBI network box is fitted on or just inside the house. It belongs to the network, not the retailer. Keep it if you switch.
• The speed profiles. NBI wholesales 500 Mb down / 50 Mb up, 1 Gb / 100 Mb and 2 Gb / 200 Mb. Not symmetrical. A retailer quoting “500/500” on NBI is quoting its SIRO product by mistake — ask which network the quote is for.
• The install. NBI arranges the appointment and an NBI engineer (or its contractor) runs the drop — aerial from the nearest pole in most cases, underground where there is a duct. The visit is one hour to two days depending on the site.
• The connection charge. For a standard residential connection there is no NBI connection fee: the network build is state-funded. NBI only asks for a customer contribution where the design needs “significantly more works than usual” — very long private lanes, new poles, new ducting. The figure widely reported for that threshold is a connection costing NBI more than about €5,000. The retailer tells you before any work starts.
• Cooling-off. 14 days on a distance sale, every retailer, under Irish consumer law.

So when a retailer charges an activation fee — Digiweb’s €49.95 on NBI 500, for instance — that is a retailer fee, not an NBI fee. It pays for the router and the admin, not the engineer.

What differs: the six things that change the bill

Two things the table cannot show. Router: Vodafone, Sky and Eir ship their own Wi-Fi 6 hubs; Digiweb sends a “best in class WiFi 6 modem”; Pure and Imagine a standard ISP router. All plug into the ONT and all can be swapped for your own. Support: Digiweb and Pure are the names that come up for getting a person on the phone; Vodafone and Sky are app-first; Eir’s reputation is the weakest of the six. On NBI the retailer cannot fix the line — it logs a ticket with NBI — so what you are buying is how fast that ticket gets raised.

NBI 500 Mb: what two years really costs

Intro prices are six- or twelve-month teasers. Two years is the honest yardstick, because that is how long most people stay before they bother switching. Figures below are published prices in August 2026, assuming you stay on the same plan and let the thereafter price land. They exclude in-contract April rises — noted separately — and assume a standard NBI connection (no contribution).

Read it honestly. Sky’s 24-month plan is the cheapest two-year bill on NBI 500 — if you never want to leave, because month 25 is €67.50. Vodafone is €30 dearer, rises €3.50 each April, and still takes our top slot because €40 is where it stays. Pure’s €1,020 is the best 12-month contract by a distance. Digiweb’s two-step 500 is dearer than its own 1 Gb. Eir’s €1,331.76 is the price of not ringing anyone in month 12.

NBI 1 Gb: the two-year table

NBI 1000 is a 1 Gb / 100 Mb profile. For a family house with a couple of people on video calls it is the tier to have, and on NBI it is often barely dearer than 500 once you look past month six.

The surprise is Eir: €39.99 flat for 24 months is the cheapest 1 Gb two-year bill on NBI, and its 1 Gb tile is the same price on Open Eir and NBI. The catch is everything after: €85.99 thereafter, a €4 April rise from 2027, and the 12-month version of the same plan carries a €149.99 install. Confirm the NBI quote at your Eircode before you assume the tile applies. Vodafone’s 1 Gb at €35 → €50 is the one we would actually sign, and it is only €10 a month more than its 500. Digiweb’s HyperPulse 1000 with free install beats its own NBI 500 by €20 over two years — if 1 Gb is at your Eircode, take it. Sky and Pure are identical at 1 Gb; Pure has no April rise. Speed-need check: what speed do I need?

Order to install: what happens and how long it takes

This is the same with every retailer because NBI runs it. What differs is how well the retailer keeps you informed in between.

1. Check the Eircode twice — on the NBI map (Passed or Connected) and on the retailer’s own checker. Some retailers lag the NBI map by days; Vodafone’s checker in particular sometimes shows only Open Eir at an address NBI has just passed. Ring them.
2. Order from the retailer. NBI will not take your order. The retailer places a wholesale order and NBI schedules the appointment “on behalf of your provider”. You get an AM, PM or all-day slot.
3. Lead time. Retailers quote “around two weeks” for a standard drop, and that is about right when the pole is outside the gate — most boards.ie reports land between two and four weeks from order to light. Long private lanes, a wayleave across a neighbour’s field, or a new duct push it to six to eight weeks. Pre-orders convert to orders automatically when the area goes live.
4. The visit. One hour to two days. Aerial drop from the pole, ONT fixed on the wall, a short internal cable if you want it in a room rather than the porch — tell the engineer on the day, not afterwards.
5. Activation. The retailer lights the line, usually the same day or the next. Plug its router into the ONT.

The old line. NBI is a new, separate connection. It does not use the Eir copper or the wireless dish, and nobody cancels those for you. If you are coming off Open Eir FTTC or a fixed-wireless plan, give notice the day the NBI line is live — not before, and not a month after. If you are on a 24-month 5G or wireless contract that is not up, check early termination fees: the fee is usually the remaining months, and it is still often cheaper than paying both for a year. The only thing to keep is a landline number you care about; port it to the new retailer before cancelling the old one, or it dies with the copper. Do I need a landline?

Our six NBI retailers, ranked

1. Vodafone — best NBI provider overall

Score 9.3. 500 Mb at €25 for six months then €40 on 24 months (€35 for six months then €40 on 12); 1 Gb at €35 → €50. Those thereafters are the standing prices — no €67.50 surprise, no haggling call in month 12. The €3.50 April rise is built in and applies inside the contract, which is the honest reason it is not cheaper than Sky over two years. €10 a month off with a Vodafone mobile plan. Also sells GigaCube 5G, so one account can bridge a house from “passed” to “connected”. Upload on NBI is 50 Mb (500) or 100 Mb (1 Gb), whatever the SIRO-style “500/500” tile says — ask. Vodafone review.

2. Pure Telecom — fairest 12-month NBI contract

Score 9.1. Irish-owned, Pure Fibre 500 at €35 → €50, Pure Fibre 1000 at €40 → €70, free install, 12 months, and ComReg Compare flags it as a retailer without a built-in annual rise. €1,020 over two years on 500 Mb. Human on the phone. If you do not want a 24-month tie and you do not want to set a reminder to haggle, this is the one. Pure Telecom review.

3. Sky — cheapest two-year bill, harshest landing

Score 8.8. 500 Mb at €30 for 12 months or €35 flat for 24 — the latter is the cheapest NBI 500 two-year total on this page at €840. The problem is the €67.50 standard price you land on, which Sky raised by €3.50 in April 2026. Take the 24-month plan if you will stay put and you want Sky TV anyway; take the 12-month one only with a calendar alert for month 11. Sky review.

4. Digiweb — the NBI specialist, buy the 1000 not the 500

Score 8.7. Irish-owned, Switcher.ie 2026 Best Alternative Network, and the retailer that has been on NBI since the first poles. HyperPulse NBI 1000 is €44.95 → €54.95 with free install; NBI Fibre 500 is a two-step €34.95 for six months, €49.95 for months 7–12, then €54.95, plus a €49.95 activation — which makes it €20 dearer over two years than the faster plan. NBI 2 Gb is €59.95 → €69.95. “No CPI Increase” on every NBI tier. Best support reputation of the six. Digiweb review.

5. Eir — yes it sells NBI; no, it is not the cheapest way to have it

Score 8.3. Eir retails NBI through eir.ie/nbi alongside Open Eir fibre and 5G (it does not sell SIRO). 500 Mb at €34.99 then €75.99; 1 Gb at €39.99 flat for 24 months then €85.99, with a €149.99 install on the 12-month version; and a flat €4 April rise from 2027. The 1 Gb 24-month plan is a genuinely cheap two years if you will leave on time. Most people do not. Our dataset has no NBI-specific Eir tier, so confirm the NBI quote and upload speed before signing. Eir review.

6. Imagine — rolling NBI with no contract

Score 8.1. Fibre Starter 500 at €45 for six months then €55, no contract, leave anytime, price freeze to December 2030 on selected plans. Dearest of the five fixed-price 500 plans over two years (€1,260) but the only one you can walk away from in month seven. Makes sense for a rental, a holiday home, or a house you will sell. Imagine review.

How we ranked the NBI retailers

Order is by our published score from the national dataset, because the product is identical and the score already weights the things that differ: contract fairness, year-two cost, built-in rises, service and reliability. We then check each retailer’s NBI-specific plan and ladder, and show the 24-month maths so you can disagree with us.

• Thereafter beats intro. A €30 month-one price that becomes €67.50 is not a €30 plan.
• Built-in rises count. Vodafone’s €3.50 and Eir’s €4 Aprils apply inside the contract. Pure, Digiweb and Imagine have no such clause.
• Activation is a retailer fee. NBI’s standard connection is free; we count Digiweb’s €49.95 against it on the 500 plan.
• Contract length is neutral unless the longer term is genuinely cheaper — Sky’s 24-month €35 and Eir’s 24-month €39.99 are, and we say so.
• We do not invent Mbps. NBI’s profiles are the speeds; no retailer delivers faster glass.
