Student broadband in Ireland is usually a renter problem, not a speed-test problem. You need something that works this week, that you can take to the next house, and that does not leave an early-termination bill when the lease ends. That is why this ranking starts with Three 5G home — no engineer, self-install router, portable — then Imagine on a rolling monthly plan, then Starlink as a last resort for rural student houses fibre and 5G cannot reach.
Fibre still wins a year-long let with landlord permission. Sky’s 500 Mb is regularly the cheapest fibre intro at €27.99/month (thereafter about €50). Pure’s 100 Mb from €30 is the no-hike fibre floor. Virgin’s €30 intro is only a bargain on a Virgin street, and only in year one. Do not order an Open Eir or NBI install into a house you might leave in May unless the landlord has said yes in writing.
Prices below are advertised plans from our August 2026 dataset, not lab Mbps. Check the Eircode, then read the contract length against the lease. Moving house and rolling plans: broadband when you move and no-contract broadband.
Why 5G comes first for most students
A fibre order is an appointment. A 5G home order is a router in a box. For a shared house in September, a new-build waiting on OpenPort, or a room you might not keep past Christmas, that difference matters more than whether the ad says 500 Mb.
- No engineer. Three (and Imagine 5G) skip the Open Eir / NBI / Virgin install calendar. Plug in, wait for the cell, done.
- Portable. Take the router to the next let. Fibre stays in the wall; you start again at the new Eircode.
- No landlord drill. FTTH often needs access, a box on the gable, and someone home for the engineer. A 5G router sits on a windowsill.
- Cheapest number on the board. Three’s promotional unlimited 5G is €25/month for 24 months (advertised 500 Mb, thereafter €40). That undercuts every fibre intro we track — with the usual 5G caveats.
| Retailer | What students actually buy | Intro / mo | Contract | Thereafter |
|---|---|---|---|---|
| Three | Unlimited 5G home, self-install (advertised 500 Mb) | €25 promo | 24 months | €40 |
| Three | Unlimited 5G, 12-month tariff | €44.99 | 12 months | €50 |
| Imagine | 5G Home Basic (650 GB cap, advertised 300 Mb) | €40 | Monthly | €40 |
| Imagine | 5G Home Unlimited | €50 | Monthly | €50 |
| Starlink | Residential 100 Mb (rolling) | €35 | Monthly | €35 |
| Sky | 500 Mb fibre — year-long let + landlord yes | €27.99 | 12 months | €50 |
The trap in that table is Three’s promo. €25 for 24 months is the cheapest intro in our dataset, but a 24-month mobile-broadband contract outlasts most academic years. If you will move in June, model the early termination fee or take Imagine’s leave-anytime 5G instead. The 12-month Three tariff at €44.99 is not cheap compared with Sky 500 fibre.
5G is not fibre. Advertised 500 Mb on Three is a mast ceiling, not a line-speed guarantee. Evening cell congestion, upload and latency lose to FTTH/SIRO. Use it because you need internet this week and you might move — not because it “beats Sky”. Full Three broadband review.
Renters, deposits, landlord permission
Irish student lets are short, shared, and allergic to holes in walls. Rank the product by what the lease actually allows, not by the comparison-site sort.
- Landlord permission for fibre. Open Eir FTTH, SIRO, NBI and Virgin all need a premises install. Ask in writing before you order. A “yes, the last tenants had Sky” is not the same as a new NBI drop. If the answer is no, stop shopping fibre.
- Deposits and kit. The fibre intros we track list €0 setup. Starlink hardware terms change — kit included vs a deposit — confirm at checkout, not from a screenshot. Three and Imagine ship a router; do not lose it at the end of term.
- Whose name is on the bill. One housemate signing a 12- or 24-month contract is how people inherit an ETF when the WhatsApp group dissolves in May. Prefer monthly (Imagine, Starlink) or be explicit about who stays for the term.
- Cooling-off. Retailers in our dataset quote 14 days. That is for distance contracts, not a free exit in month eight.
If the house already has a live line, switching retailer is usually easier than a new connection — ComReg switching is provider-led. A new drop into a rental is a different job. Walkthrough: how to switch broadband and moving house.
| Situation | Default buy | Avoid |
|---|---|---|
| 9-month academic let, no drill allowed | Three 5G or Imagine rolling 5G | 12-/24-month fibre; NBI engineer |
| 12-month house share, landlord signs off | Sky 500 Mb fibre (€27.99 intro) | Virgin thereafter (~€70) if you will stay into year two |
| Rural student house, no mast, no fibre date | Starlink residential 100 Mb (€35 rolling) | Treating the dish as “fibre” |
| Moving at Christmas or between lets | 5G you can pack; see moving-house guide | Locking a new FTTH order into the old Eircode |
Moving house and short contracts
Students move. Broadband mostly does not. Fibre is tied to the Eircode; 5G and satellite are tied to a kit. If the lease is shorter than the minimum term, the honest product is a rolling plan — or a 5G promo you are sure you can finish. Longer guide: broadband when you move house. Rolling tariffs: no-contract broadband.
| Plan type | Takes with you? | Leave-anytime? | Student fit |
|---|---|---|---|
| Three 5G (24-month promo) | Yes — pack the router | No (ETF if you leave early) | Cheap if you will keep it 24 months; risky for one academic year |
| Three 5G (12-month) | Yes | No during the term | Dearer (€44.99). Align with a 12-month lease |
| Imagine 5G / fibre starter | 5G yes; fibre no | Yes on 5G home (leave-anytime pledge) | Best “I might leave in March” wired-alternative |
| Starlink residential | Yes — pack the dish | Yes (rolling monthly) | Rural last resort; thereafter equals intro (€35 on 100 Mb) |
| Sky / Pure / Vodafone / Eir / Digiweb fibre | No — new order at the next house | No during the 12-month intro (Eir 1 Gb is 24 months) | Year-long lets with landlord permission only |
| Virgin cable | No — and only on a Virgin street | No during the 12-month intro | Urban year-long let on the footprint |
Imagine’s selected plans advertise a price freeze until December 2030; on the three tariffs we track, thereafter equals intro (€40 / €50 / €55). Confirm the freeze is on the tariff you join. Fibre Starter 500 at €55 monthly is a renter-friendly fibre contract where they have wholesale access — it is still an install, so landlord rules still apply.
When fibre wins: year-long lets
If you have a 12-month lease, written permission, and a checker that says FTTH, SIRO, NBI or Virgin at the door, stop buying 5G out of habit. Wired is calmer for four laptops, a TV and evening congestion. Rank fibre by intro, then look at thereafter before you sign.
| Fibre / cable (advertised) | Intro / mo | Thereafter / mo | Contract | Down / up |
|---|---|---|---|---|
| Sky 500 Mb Ultrafast Plus | €27.99 | €50 | 12 months | 500 / 100 Mb |
| Pure Telecom 100 Mb | €30 | €40 | 12 months | 100 / 100 Mb |
| Virgin Media 500 Mb | €30 | €70 | 12 months | 500 / 50 Mb |
| Virgin Media 1 Gb | €30 | €72 | 12 months | 1000 / 50 Mb |
| Pure Broadband + phone 500 Mb | €35 | €45 | 12 months | 500 / 100 Mb |
| Eir 500 Mb | €34.99 | €75.99 | 12 months | 500 / 100 Mb |
| Digiweb SIRO Gigabit | €37.95 | €50 | 12 months | 1000 / 1000 Mb |
| Vodafone 500 Mb or 1 Gb | €40 | €55 | 12 months | 500/500 or 1000/1000 Mb |
Sky is the fibre teaser most student houses should beat on price. Pure 100 Mb is enough for a quiet two-person flat and the thereafter step is only €10. Virgin’s €30 1 Gb is the same intro as 500 Mb — take the gig on a Virgin street — but year two is ~€70–€72. Vodafone often prices 500 Mb and 1 Gb the same (€40); take the gig on SIRO if the Eircode has it. Eir’s coverage is the product; the thereafter (~€76) is why students should not “just stay with Eir”.
Availability is local. Open Eir retailers cannot use Virgin’s network. Check broadband by Eircode before anyone in the house pays a deposit on a brand.
How we ranked student broadband
This is not the cheapest-fibre table and it is not the overall best broadband in Ireland order. The cards above follow a renter decision tree:
- Three 5G first — no engineer, portable, cheapest intro we track (€25 promo).
- Imagine second — rolling monthly, leave-anytime on 5G, freeze on selected plans, thereafter = intro on the tariffs we list.
- Starlink third — last-resort satellite for houses with no fibre and no usable mast. Rolling monthly. Not fibre.
- Then fibre / cable — Sky’s cheapest 500 Mb intro first, then the other retailers by typical intro (Pure, Virgin, Eir, Digiweb, Vodafone) for year-long lets with landlord permission.
FROM / THEREAFTER / CONTRACT / SPEED on each card are the cheapest tariff we list for that retailer in August 2026. SPEED is advertised download on that tariff, not a lab test. Affiliate links never change the order.
Our student picks in brief
Three — default for most renters
€25 a month for 24 months on promotional unlimited 5G, advertised 500 Mb, thereafter €40. Self-install, no landline, take it with you. Watch the 24-month term against a 9-month lease. Three review.
Imagine — rolling plan if you might leave
5G Home Basic €40 (650 GB cap), Unlimited €50, Fibre Starter 500 €55 — thereafter equals intro, monthly. Leave-anytime on 5G; freeze to December 2030 on selected plans. Imagine review.
Starlink — rural last resort, not a campus toy
Residential 100 Mb €35 rolling. Buy it when fibre and 5G are a no. Kit terms (deposit vs included) change. Starlink review.
Sky — cheapest fibre intro for a 12-month house
€27.99 for 12 months on 500 Mb Ultrafast Plus, Open Eir / SIRO / NBI, thereafter about €50. Landlord permission first. Sky review.
Pure is the no-hike fibre stay (100 Mb from €30). Virgin is urban download on its own streets. Digiweb is the NBI / regional SIRO name. Vodafone is SIRO symmetry if the house will actually sit still. Eir reaches addresses others miss — then the April rise. More on short contracts: no-contract broadband.
