Working from home is where Irish broadband ads fall apart. A 1 Gb download looks heroic on the box; a video call, a VPN into the office and a cloud backup all live or die on upload. Cable and 5G can look fast on a speed-test site and still freeze your camera when two people join a Teams call. Full fibre — especially SIRO, which is often symmetrical — is the product that actually matches the job.
Vodafone leads this ranking because it co-owns SIRO with ESB and routinely sells 500 Mb and 1 Gb full fibre with matching upload, often at the same €40 intro (August 2026). Digiweb and Pure Telecom sell the same class of line on SIRO and NBI. Virgin Media is usually the wrong WFH pick even when it is the fastest download in the estate: advertised upload on the 1 Gb plan is 50 Mb. Three 5G, Imagine wireless and Starlink are honest stopgaps when no fibre is at the Eircode.
Nothing in this list is national. Check the address first — find broadband by Eircode — then pick the retailer on the network you actually have. We rank on published prices, contract terms and advertised upload. We do not invent lab Mbps.
Why upload (and symmetry) matter more than the gigabit badge
A download-heavy speed test is a poor proxy for a working day. Zoom, Teams and Google Meet send your camera, microphone and screen-share upstream. iCloud, OneDrive and Git pushes do the same. If two people in the house are on calls, or you are uploading a deck while a partner streams 4K, a 50 Mb cable upload fills up fast — even if the download still shows 900 Mb.
Symmetrical means the advertised upload matches the download (500/500, 1 Gb/1 Gb). That is the usual SIRO shape, and it is what NBI full fibre often looks like too. Open Eir FTTH is frequently asymmetric at the popular 500 Mb tier (Sky’s quoted 500 Mb plan is 500 down / 100 up). That 100 Mb is still enough for most WFH — it is just not the same product as SIRO 500/500.
Rule of thumb: one HD video call wants roughly 3–8 Mb up. Two concurrent calls plus cloud backup want headroom, not the minimum. 50 Mb up (typical Virgin 1 Gb cable) is workable for a quiet house and tight for a busy one. 100 Mb+ up is the comfortable WFH floor. Symmetrical 500 Mb or 1 Gb is what you want if you send large files, run a NAS, or share the line with another remote worker.
SIRO vs cable vs 5G: the WFH version
Irish “fibre” is four different physical networks plus wireless. For working from home they are not interchangeable.
| Technology | Typical advertised upload | WFH fit |
|---|---|---|
| SIRO FTTH | Often symmetrical (500/500, 1 Gb/1 Gb, 2 Gb/2 Gb) | Best default where the ESB poles reach — Vodafone, Digiweb, Pure, Sky |
| Open Eir / NBI FTTH | 100–1,000 Mb up depending on the tier (NBI often symmetrical) | Excellent once it is actually at the door; confirm FTTH not FTTC |
| Open Eir FTTC | Copper last mile, often ~20–30 Mb up on a “100 Mb fibre” plan | Light WFH only — this is not full fibre |
| Virgin cable | 50 Mb up on 500 Mb and 1 Gb; 100 Mb up on 2 Gb (August 2026 quotes) | Fine for one quiet desk; the wrong buy if upload is the job |
| 5G home (Three, some Vodafone / Imagine) | Not a wired guarantee — follows the mast | Renters and “need it this week”; latency and evening cells hurt calls |
| Starlink | Quoted 15–30 Mb up on residential tiers | When fibre and 5G are no; monthly, leave when NBI arrives |
The full wholesale map is on Open Eir vs SIRO vs NBI vs Virgin. Cable is not “bad internet” — it is a different shape of internet. Buy it for download in a Virgin street; do not buy it because a comparison site sorted on headline Mb.
How much speed does a WFH household actually need?
Most Irish desks do not need 2 Gb. They need stable upload, low enough latency for calls, and enough leftover download that a teenager’s Netflix does not wreck the stand-up.
| Household | Download | Upload to aim for |
|---|---|---|
| One person, HD calls, email, browser | 100 Mb is enough | 20–50 Mb |
| One remote worker + evening streaming | 500 Mb is the Irish default | 100 Mb (or SIRO 500/500 if you can get it) |
| Two WFH desks, 4K TV, cloud backup | 500 Mb–1 Gb | Symmetrical 500 Mb or 1 Gb |
| Creators, NAS, constant large uploads | 1–2 Gb | Match the download — SIRO / NBI gigabit |
If you are still choosing a tier rather than a brand, use what speed do I need?. The short version for WFH: take SIRO or NBI gigabit when it costs the same as 500 Mb (Vodafone often does this), and do not pay Virgin 2 Gb rates just to claw back 100 Mb of upload.
How we ranked them for working from home
Order on this page is not the same as the overall best broadband in Ireland hub. We sort live retailers by maximum advertised upload on the plans we quote, then reliability rating, then overall score — and we keep fibre and cable above 5G, wireless and satellite. That is why Virgin, despite a 9.5 speed sub-score, sits below SIRO retailers: 100 Mb is its best quoted upload. Three sits near the bottom because 5G home does not quote a wired upload at all.
- Advertised upload and symmetry. Taken from the plan rows in our dataset — not a lab. Vodafone and Digiweb quote 2 Gb/2 Gb; Pure quotes 1 Gb/1 Gb; Sky’s popular 500 Mb is 500/100.
- Reliability and contract. A jittery cell or a year-two bill of €76 is a WFH problem too. Pure’s lack of a built-in annual hike matters if you will stay.
- Coverage honesty. SIRO is towns and suburbs. Virgin is a closed urban footprint. NBI is rural once passed. 5G and Starlink exist so we can say “use these when the pole is empty” without pretending they are fibre.
We still do not invent lab Mbps. Line-level tests will be added as we instrument homes. Affiliate commissions never buy a higher place.
Our top WFH picks
Vodafone — best SIRO desk
The ranking leader for a reason: 500 Mb and 1 Gb full fibre are often the same €40, both quoted as symmetrical, and Vodafone co-owns SIRO. If both tiers are at the Eircode, take the gig. Thereafter is typically €55, and in-contract increases exist — model year two. The Vodafone broadband review has the contract detail.
Digiweb — best rural / NBI WFH
When the house is on the National Broadband Plan rather than a town SIRO cabinet, Digiweb is the specialist to compare: NBI 500/500 and 1 Gb/1 Gb, plus SIRO gigabit in regional towns. It will not beat Sky on a cheap urban 500 intro, and it should not have to. See the Digiweb review.
Pure Telecom — fairest stay-put contract
Same wholesale Open Eir / SIRO / NBI lines as the big brands, with a 100/100 starter and symmetrical 500 and 1 Gb tiers. The point is the contract: Pure is one of the retailers ComReg Compare flags for plans without a built-in annual increase. Pay more than Sky’s teaser, keep more in year two. Pure Telecom review.
Sky remains the cheapest 500 Mb intro we regularly see (500/100) — fine for one quiet desk if SIRO symmetry is not at the pole. Virgin is the fastest urban download; it is not the WFH upload pick. Three 5G is what you buy for a rental this week, not for two daily stand-ups on a busy cell. When NBI is still a date on a map, read best rural broadband.
