Broadband in Belfast: what reaches your door, and what you should pay

Check your address first

Direct answer: Most Belfast homes will have three or more gigabit networks to pick from by 2029, on Ofcom’s figures, and none of those networks covers every street or every block. The answer that counts is the one your own address gives.

The rest of this page explains what that check will show you and why. Whether your house or your block is on Openreach’s fibre, Virgin Media’s network or both decides which of the sections below describe your home and which describe the house across the road.

North, South, East and West: the four seats

Direct answer: In January 2026, full fibre reached 94.7% of homes in the Belfast council area, according to Ofcom, and the four seats that carry the city’s name ran from 96.2% in Belfast North to 93.5% in Belfast South and Mid Down. Gigabit-capable coverage, which adds Virgin Media’s cable, was at least 97% in all four.

Ofcom’s Spring 2026 update, published on 13 May 2026, gives a January 2026 figure for every council and every Westminster seat in the UK. These are counts of homes rather than businesses, on the same footing as Northern Ireland’s 95.5% and the UK’s 81.8%. Two of Ofcom’s definitions matter here. Full fibre is “An access network structure in which an optical fibre runs all the way from customers’ premises to the local exchange or access node.” Gigabit-capable is “A network connection to a customer’s premises capable of delivering download speeds of 1 Gbit/s or more.” Virgin Media’s cable passes the second test without passing the first, and in Belfast the distance between the two is 3.2 points: the homes where a gigabit line arrives by cable and not yet by fibre.

Read the compass and the spread is narrow. Belfast North leads at 96.2%, Belfast East and Belfast West sit within a point of it, and Belfast South and Mid Down, the one seat whose name reaches out of the city into the farms and villages of Mid Down, is lowest at 93.5%. The council area itself, at 94.7%, comes in below three of the four seats, which sounds odd until you look at the edges: the 38,421 homes the seats take in from neighbouring councils are better served than the city’s own, at 97.5%. Across Northern Ireland the council area is eighth of 11 for full fibre and second for gigabit, and across the UK’s 361 councils it is 27th and 11th.

Ofcom publishes a row for every Westminster seat on the 2024 boundaries, and four of them carry Belfast’s name; the “which part” column is our rough guide, not a boundary. Between them the four seats count 199,354 homes against the council area’s 160,933, because they reach over the city boundary into Lisburn and Castlereagh, Antrim and Newtownabbey and Mid Down. The full fibre and gigabit columns are the share of homes (residential premises) able to get each, from Ofcom’s January 2026 data published 13 May 2026. Tap a column heading to sort.Swipe sideways for the homes column.

Two things to keep in mind as you find your row. Each seat holds forty-five to fifty-five thousand homes, and the streets inside one seat differ far more than the four seats differ from each other. And a home that can get full fibre is not one that has it, which is the subject of the next section and the most useful number on this page.

Built but not bought: Belfast’s take-up gap

Direct answer: In January 2026, 47% of the Belfast premises that could get full fibre had a full fibre line, Ofcom says: the lowest of Northern Ireland’s 11 councils, 15 points behind the next lowest, Mid Ulster at 62%. Across the UK the figure is 47% of all premises with access to full fibre, so Belfast is level with the UK as a whole and well behind the rest of Northern Ireland.

The regulator and the biggest builder tell the same story from different ends. Ofcom counts every network and puts Belfast at 47% of covered premises switched, against 64.8% for Northern Ireland on our weighting of the 11 council rows. Openreach counts only its own wires, and said of the whole of Northern Ireland on 16 May 2025 that “Full Fibre broadband is already being used by over 64% of end customers on the Openreach network in Northern Ireland”. Its acting director for the region added that “The rollout of this technology is helping to level the playing field between urban centres and rural areas”. In Belfast, where the fibre arrived early and the uptake has been slowest, that field is already level: the fibre is in the street, and the step left is the order.

Ards and North Down leads Northern Ireland at 75%; every other council is at 62% or more. Ofcom gives the figures without the reasons, and this page will not make one up, but two facts further down fit the picture. Belfast is the council where the most households rent, 46.8% of them, and a tenant can need a landlord’s say before an engineer drills a wall. And Virgin Media switched its whole Northern Ireland cable network to gigabit speeds in November 2020, so a Belfast household on that cable has had a fast line for years and little reason to look again. Neither is a reason to wait; both are reasons to check what the better line now costs.

There is a deadline too, and Belfast met the first part of it early. When three quarters of the homes on an exchange can get full fibre, Openreach stops selling copper broadband there, and on 31 January 2027 the old analogue phone network closes for everyone. Thirteen exchanges with a Belfast location passed the first mark in 2021, in the very first rounds in the UK, which is why the switch-off has a section of its own below.

The networks behind Belfast’s broadband

Direct answer: Openreach, whose fibre carries most of the big brands, and Virgin Media, which is rebuilding its own Belfast network as full fibre, are the two you will meet at most addresses. Fibrus, the Northern Ireland builder, has public contracts across the rural north; its own site would not let us read what it says about Belfast. YouFibre, nexfibre, Hyperoptic and CityFibre name nowhere in the city.

Every broadband bill has two names behind it: the brand that sends it and the network it runs on. In Belfast the network is almost always Openreach or Virgin Media, and you can often choose between them at the same address. Below is what each network says in its own words, from its own site, with the date it said it. Old dates stay in on purpose, because the age of a claim is part of the claim.

Openreach, under the brands most people know

BT, Sky, TalkTalk, Vodafone, EE, Plusnet and most smaller brands sell over Openreach. Its Northern Ireland figures are for the whole region and not the city. On 16 May 2025 it said “Openreach Northern Ireland has announced that it has successfully reached 90 per cent coverage in its rollout of Full Fibre broadband, becoming the first region within the Openreach UK network to hit this milestone”. That was part of a build to “more than 830,000 homes and businesses across the region”, and it added that “Openreach’s plans remain on track to reach 97% coverage of Northern Ireland”. Its deputy chief executive called it the moment that “This milestone firmly establishes Northern Ireland as the UK’s leader in Full Fibre deployment”. We found no Openreach figure for Belfast itself, so the city numbers on this page are Ofcom’s, which count every network: Ofcom’s 95.5% for Northern Ireland covers all of them, where Openreach’s 90% covers its own. Openreach’s Northern Ireland page now says simply: “Over 90% of Northern Ireland is Full Fibre ready.”

Virgin Media, rebuilding its own network

Virgin Media sells only on its own network, and it is the one company that puts a Belfast number on the record. Its article of 18 August 2025 is headed “94,867 homes in Belfast can now get Virgin Media Full Fibre broadband”. The body says “A total of 94,867 homes* in Belfast can now benefit from Virgin Media full-fibre gigabit broadband”, with the footnote “*Number of homes added to our full-fibre network in Belfast in 2025 as of June.” In other words, it counts the Belfast homes added to Virgin’s full fibre network in the first half of 2025, not the size of its whole Belfast network. The same article says “our full-fibre broadband comes with the option to get symmetrical download and upload speeds of up to 2Gbps”. It adds that “We invest £2 billion a year in our networks and services and are also in the process of upgrading our entire fixed network”. Its advice for checking is short: “If you’re unsure what’s available where you are, just stick your postcode into our broadband checker”. Five years earlier, in November 2020, it switched its whole Northern Ireland network to gigabit speeds, “nearly 400,000 homes across the region”, and said: “This includes homes in Belfast, Ballymena, Carrickfergus, Craigavon, Derry, Lisburn, Newtownabbey, Portadown and other towns.” It also “won a Government-backed Local Full Fibre Network (LFFN) contract in Belfast”, with “more than 200 Belfast City Council locations connected to its ultrafast network”.

One thing Belfast does not have is nexfibre, the builder whose fibre Virgin sells in parts of Britain. Its coverage report to the end of December 2025 names no place in Northern Ireland; its foreword talks instead of “more than 2 million Virgin Media O2 premises, which will be upgraded by nexfibre”. In Belfast, on Virgin’s own account, the full fibre is Virgin’s.

Fibrus, the Northern Ireland builder

Fibrus is the company the Department for the Economy chose for Northern Ireland’s two big public broadband contracts. Of the first, the department says “Project Stratum extended Next Generation Access (NGA) broadband infrastructure to over 81,000 premises across Northern Ireland that could not access NGA broadband services of 30Mbps.” It adds that “Fibrus Networks was appointed as the contractor for Project Stratum in November 2020, and the Project was finished in June 2025.”, and the total funding came to £200m. Of the second, announced on 16 December 2025: “The £34.6m contract, funded by the UK government, begins immediately and will bring gigabit-capable broadband to over 9,000 rural premises across Northern Ireland.” Fibrus’s chief executive, Dominic Kearns, said in the same release: “Delivering for rural communities is at the heart of what we do at Fibrus and this contract allows us to continue to provide more homes and businesses with the opportunities proper connectivity brings.” Both contracts are for rural homes, which is why neither reaches into the city.

What Fibrus sells in Belfast itself we cannot tell you in its own words. On 20 October 2026 its website showed our browser a “Verify you are human” check and went no further, and we do not quote a company second-hand. Ofcom’s plans file does not name builders either, but it expects 86.1% of Belfast homes to have three or more gigabit networks by 2029, which means at least three networks to choose between at most Belfast addresses. If Fibrus is one of them in your street, the postcode check will show it.

The names you will not see in Belfast, yet

YouFibre, the brand on Netomnia’s network, lists one place in Northern Ireland: “YouFibre delivers 100% full-fibre broadband to Londonderry”, and nowhere in Belfast. Hyperoptic, which wires blocks of flats, has no Belfast page (the address answered “Sorry, we cannot find that page” on 20 October 2026). CityFibre’s coverage page names no place in Northern Ireland, and nor does nexfibre’s report. Ofcom’s file puts the number of gigabit operators expected in the council area by 2029 at 1 to 5, which fits a city served by two big networks and a third arriving.

What is coming by 2029

Direct answer: Almost every home, and a choice of three for most. Ofcom’s planned deployments file puts Belfast at 99.8% of homes with full fibre by January 2029 and 86.1% with three or more gigabit networks, the highest share of Northern Ireland’s 11 councils; Antrim and Newtownabbey is next at 74.0%.

Each year Ofcom asks every builder where it plans to be in three years and adds the answers up by council. Belfast’s January 2029 line reads 99.8% full fibre and 99.9% gigabit-capable, and the gigabit figure holds at 98.3% when only the plans Ofcom rates ‘High Confidence’ are kept, the ones that “have reached both the low-level design stage and for which funding has been committed”. On the same plans 97.8% of homes will have two or more gigabit networks and 86.1% three or more. Northern Ireland as a whole moves from 95.5% to 99.3% for full fibre; Antrim and Newtownabbey, Lisburn and Castlereagh and Ards and North Down all finish in the high nineties too.

The figure to look for if your street has been missed is Ofcom’s count of Belfast postcodes that no builder plans to reach with gigabit by January 2029: seven, in a city of 149,208 households. Ofcom’s Belfast row shows four planned new lines paid for from public funds, because the public money in Northern Ireland goes to the countryside. Of the homes Project Stratum reached, the department says “These predominantly rural premises had previously had download speeds below 30Mbps available.” The new Project Gigabit contract is for rural homes too. If your home is one of the few left out, the department’s release says “This includes a premises checker to enable homeowners and businesses to check if their premises will benefit from Project Gigabit.”

Your exchange and the end of the old phone line

Direct answer: Thirteen exchanges with a Belfast location stopped selling copper in 2021, in the first rounds anywhere in the UK, and four of them were among the thirteen that went first of all, on 29 June 2021. On 15 October 2026 Openreach said “around 35,000 customers across Northern Ireland still need to migrate from the old copper network”, ahead of the old network closing on 31 January 2027.

Two changes tend to get mixed up here. The first is the switch-off of the old analogue phone network, which happens on one date everywhere: “On 31 January 2027, all traditional phone lines will be going digital - so it’s important to switch now.”, in Openreach’s words. The second is copper “stop sell”, which comes exchange by exchange and changes only what can be sold, not what is already working. Openreach’s trigger is that “Stop Sell is triggered when a majority (75%) of premises connected to a particular exchange can get ultrafast Full Fibre”. After that, anyone moving in, switching or upgrading in that exchange area is sold a digital line over fibre. Belfast reached that point before almost anywhere else.

The record is BT Wholesale’s list, “Product stop sells and FTTP exchange upgrades”, which runs to “1,747 exchanges moving to FTTP” and notes that “a UK wide WLR Stop Sell commenced on 5 September 2023”. It explains the start like this: “Due to delays caused by the coronavirus pandemic the first tranche of upgrades was split in two. As a result, 13 stop sells went live on 29 June 2021 as part of Tranche 1a. The rest went live on 13 October 2021”. In its November 2025 edition, thirteen rows carry a Belfast location. Four of them, Belfast Cregagh, Belfast Knock, Ballysillan and Belfast Fortwilliam, are in Tranche 1a on 29 June 2021; the other nine, including Belfast City, Malone, Ormeau and Stormont, are in Tranche 1b on 13 October 2021. Lisburn, Holywood and Glengormley followed on 29 April 2022 and Castlereagh on 19 August 2025. No Belfast exchange appears in Openreach’s 2026 rounds, because there was none left to add. Openreach’s September 2026 league table of cities moving to digital phones covered ten cities in Great Britain and not Belfast, so the Northern Ireland count of 35,000 is the one to go on.

BT Wholesale names exchanges by building, not by the streets they serve, so the name is a clue and not an answer: the exchange behind your line is the one Openreach’s checker returns. Stop sell changes what can be sold at the exchange, not what you have now. The list is BT Wholesale’s of November 2025, read on 20 October 2026; Openreach’s stop sells page always has the newest round.

For most homes the change is no more than the phone plugging into the router instead of the wall. Openreach’s Northern Ireland director, Lauren McGaughey, put it this way: “For many people, this change will simply mean moving their phone service from an old analogue connection to a modern digital one. But the important thing is to check what else might be connected to that line.” Its release is blunt about what else might be on that line: “It’s not just phones that can be connected to these lines.” It also has the reassurance most people want to hear: “The good news is that landline services are not disappearing.” If anything other than a phone depends on your line, a care alarm above all, go through the five steps in the drawing above in that order, and read our care alarm guide before the engineer comes. Our landline switch-off checker works for Belfast lines as it does anywhere else.

Terraces, flats and rented homes: who says yes

Direct answer: More than a third of Belfast households live in a terraced house and one in five in a flat, the highest shares in Northern Ireland on the 2021 census. Nearly half rent: 26.3% from the Housing Executive or a housing association and 20.5% from a private landlord. In a house you own, the only yes needed is yours; in a rented home or a block, someone else has to agree first.

NISRA’s census counts 149,208 households in Belfast. 36.8% live in a terrace against 22.4% across Northern Ireland, and 19.7% in a flat of some kind against 10.0%. Only 50.1% own their home, outright or with a mortgage, where the figure for Northern Ireland is 64.4%, and the Housing Executive alone is landlord to 25,254 Belfast households. Those three facts shape how a new line gets in more than any network map does.

The terrace is the simple case. Openreach usually brings fibre to the house from a pole in the street and Virgin Media from a chamber under the pavement. Either way, the engineer fits a small box on the outside wall and another low on the wall inside, and the router plugs into that. If you own the house, nobody else needs to be asked, and the visit is usually an hour or two.

The block of flats needs a signature first. A network can reach the front door of a building and serve nobody inside until the owner gives written permission for the cable to come in, called a wayleave. In a Housing Executive or housing association block that is one landlord deciding for every flat; in a privately owned block it is the freeholder or the managing agent. Our wayleave guide explains what is being asked and why the building loses nothing by agreeing.

The rented house needs a quick yes from the landlord before anyone drills a wall, whether that landlord is the Housing Executive, a housing association or a private owner. It is usually a small request, and a tenant’s rights to full fibre covers what to do if the answer is slow in coming. Changing provider on a line that is already there is your decision alone, as switching in a rented property explains, and students in halls near Queen’s or Ulster University have their own set-up, covered on our student halls page.

Cheaper broadband if you receive certain benefits

Direct answer: If you get Universal Credit, Pension Credit or certain other benefits, at least three of the providers that sell in Belfast offer a social tariff, the cheapest at £12.50 a month, and every one of them follows the same rule: “It costs nothing to leave. You won't pay a fee to leave the tariff before the end of your contract.”

The cheapest one for you depends on which network reaches your home. On Virgin Media’s network, Essential Broadband is £12.50 a month on a rolling 30-day contract. On an Openreach line, BT Home Essentials is £16.50 a month and Vodafone Essentials is £20 a month for up to 80 Mbps on a 12 months contract. Sky’s tariff is only for existing customers: “Our Sky Broadband Basics offer is only available if you already have Sky Broadband with us”. Our social tariffs guide lists every tariff on Ofcom’s register with who qualifies, checked by hand. If you rent from the Housing Executive or a housing association and live in a block, ask which networks are already in the building first: a cheap tariff is only cheap if its network reaches your flat.

For the seven Belfast postcodes no builder plans to reach with gigabit by 2029, help in Northern Ireland comes through the Department for the Economy rather than through you. Project Gigabit here is the department’s contract with Fibrus, and its release points to a premises checker on its Project Gigabit page. For everyone else, the cheapest route is the one at the top of this page: see what already reaches your address and what it costs.

Look up your seat

Direct answer: Choose one of the four Belfast seats to see its Ofcom figures and how it compares. The lookup runs on your own device and sends nothing anywhere.

What this page used to say

Direct answer: Five corrections: a coverage figure that was too high and a Northern Ireland lead Belfast does not have, an unsourced Virgin Media figure, a YouFibre neighbourhood list YouFibre does not publish, the wrong details of Northern Ireland’s public broadband contract, and an average speed from tests nobody can check.

If you read the earlier version of this page, some of it was wrong, and you should know which parts. It ran to nearly nine thousand words, recommended providers by postcode district, quoted typical prices, and gave figures for coverage and speed that we cannot trace to any source. Where a figure could not be traced, it has been taken out rather than softened, and where a company’s own words disagree with ours, the company’s words now stand. The “best provider for BT7” style of advice has gone too, because nobody can know what reaches a house without its address, and the check at the top of the page is where that answer is.

In short

1. Northern Ireland leads the UK for full fibre, at 95.5% of homes against 81.8%, and Belfast’s council area is at 94.7%, eighth of the 11 councils, with 97.9% able to get a gigabit-capable service.
2. The four seats that carry the city’s name run from 96.2% in Belfast North to 93.5% in Belfast South and Mid Down. The street matters more than the seat.
3. Take-up is the story: 47% of the Belfast homes that could get full fibre had taken it, the lowest in Northern Ireland, where the weighted figure is 64.8%.
4. More than a third of households live in a terrace and nearly half rent, the highest shares in Northern Ireland, so the owner’s yes is often the first step.
5. Virgin Media says it added 94,867 Belfast homes to its full fibre network in the first half of 2025. Openreach gives Northern Ireland figures only. Fibrus’s public contracts are rural, and YouFibre, nexfibre, Hyperoptic and CityFibre name nowhere in the city.
6. By January 2029, on the builders’ plans, 99.8% of homes will be able to get full fibre and 86.1% will have three or more gigabit networks, the highest share in Northern Ireland.
7. Thirteen Belfast exchanges stopped selling copper in 2021, four of them in the UK’s very first round, and the old phone network closes on 31 January 2027.
8. Only your postcode tells you which of these networks reach your home and what they cost there.

Each point carries its own date and stands on its own. We re-read this page at least once a quarter, most recently on 20 October 2026.
