Why a 25-year-old story still shapes your broadband
The line into your home today is the result of decisions made over more than 25 years: which cables were already in the ground, who was allowed to use them and where public money went. That history explains things that can seem odd. Why can so many companies sell broadband over the same cable? Why does moving to Virgin Media mean different equipment? Why did "fibre broadband" so often mean lines that are partly copper? And why is the old phone network closing by 31 January 2027?
Before 2000: dial-up over the phone line
Before broadband, getting online at home meant dial-up. A modem phoned your internet provider over the ordinary phone line, and while you were online that line was busy for calls.
How you paid changed too. ISPreview recalls that in 1995 many UK dial-up providers, AOL among them, used premium-rate numbers, then moved to local call rates and later to unmetered access (FRIACO): a set monthly fee instead of paying by the minute.
Speeds were measured in kilobits per second (Kbps), where 1,000Kbps makes 1Mbps. The V.90 dial-up standard, capable of 56Kbps, arrived in 1998, shortly before cable and ADSL broadband reached homes (ISPreview, 2025).
Dial-up lingered: about 600,000 AOL UK customers were still on it in 2006, ISPreview reported. The legal safety net lagged too: the universal service rules in place from 2003 only required a line capable of "functional internet access", which ISPreview notes dial-up could technically meet.
What it explains today: home internet started life on the phone line, which is why the retirement of the copper phone network (covered below) still affects how some homes get broadband.
2000: broadband arrives on two separate networks
Both cable and ADSL broadband were trialled in the UK in the one to two years before 2000. Then, according to Openreach, the first UK home broadband connection was installed in Basildon, Essex, in April 2000. BT's first commercial ADSL lines, running at 512Kbps, appeared the same year (ISPreview, June 2025).
So from the start there were two routes into UK homes:
- The copper phone network, owned at the time by BT and now run by Openreach. Broadband over it used ADSL, which stands for Asymmetric Digital Subscriber Line. "Asymmetric" means download speeds are much faster than upload speeds. A later version, ADSL2+, raised the maximum download connection speed from 8Mbps to 24Mbps (thinkbroadband). That 24Mbps is the technical ceiling of the standard; the "up to" figures Openreach quotes for its own copper service are lower (up to 20Mbps in 2010, up to 21Mbps today), and the speed you get also falls with distance from the exchange.
- The cable TV networks, built by cable companies such as NTL and Telewest, which carried broadband alongside TV. These later became Virgin Media.
What it explains today: the split between the Openreach network and Virgin Media's network is as old as UK broadband itself. Our guide to how Virgin Media's network differs from Openreach covers what that means inside your home, and our guide what ADSL is and what's happening to it covers the copper technology in more depth.
Opening BT's lines to rivals
Until Openreach was created, BT owned and managed the phone and broadband network itself. The regulator's answer was local loop unbundling (LLU). The "local loop" is the line between your local telephone exchange and your home; unbundling lets a rival operator run its own broadband service over that stretch instead of reselling BT's.
It took time. Reporting Ofcom in July 2004, ISPreview said early attempts at LLU between 1999 and 2001 had failed, held back by price and process problems. In May 2004 BT announced a 70% cut in what it charged other operators for unbundled lines, and Ofcom set out LLU as an important route to what it called second-generation broadband. The numbers then moved quickly: the Telecommunications Adjudicator reported 673,000 unbundled UK lines in July 2006, up from 250,000 in January 2006 (ISPreview, August 2006).
At the same time the network itself was put at arm's length. Openreach says it was created as a result of Ofcom's 2005 strategic review and opened for business in 2006, because Ofcom wanted every provider to have fair access to the network. Our Openreach guide covers what happened next, including how Openreach became a legally separate company, still wholly owned by BT, in 2017.
What it explains today: this is why so many brands sell broadband over the same Openreach line and differ mainly on price, terms, equipment and service. You can see the brands available in your area on our broadband providers page.
Cable becomes Virgin Media
On the cable side, the two big operators, NTL and Telewest, merged (ISPreview). In July 2006 the combined business, then called ntl:Telewest, completed its purchase of Virgin Mobile and said it would start marketing its broadband, TV, phone and mobile services under the single Virgin brand in early 2007 (ISPreview, 4 July 2006). That is the company we now know as Virgin Media.
In December 2008 Virgin Media launched an "up to" 50Mbps service using DOCSIS 3.0, a standard for carrying broadband over cable TV networks, with up to 1.5Mbps upload. Its cable network reached 12.6 million homes at the time. ISPreview noted that smaller fibre providers got there earlier, but Virgin was first on a national scale.
The cable network was upgraded, not replaced. Virgin Media describes it as hybrid fibre: fibre to its street cabinets, then coaxial cable ("coax") into the home, supporting more than a gigabit per second after a later DOCSIS 3.1 upgrade (Ofcom via ISPreview).
Ownership changed again on 1 June 2021, when Virgin Media O2 launched as a 50:50 joint venture of Liberty Global and Telefónica. It says it is on track to complete its full fibre upgrade by 2028, and ISPreview reports that this moves cable areas to XGS-PON full fibre, with an engineer visit needed to move a customer across. Our XGS-PON explainer covers that technology.
What it explains today: Virgin Media is a separate network, not another brand on the Openreach line, so moving to or from it can mean different equipment and an engineer visit. You can see Virgin's current offers on our Virgin Media broadband deals page.
Fibre to the cabinet: the part-fibre decade
While cable moved to 50Mbps, the phone network faced a problem: ADSL slows down the further you live from the exchange, because the whole route is copper. The fix BT and Openreach chose for most homes was FTTC (fibre to the cabinet). Fibre runs from the exchange to the green street cabinet, and the existing copper phone wire covers the last stretch to your home. The technology on that copper stretch is called VDSL2, and thinkbroadband notes Openreach caps its connection speed at 80Mbps.
The key dates, from Openreach and ISPreview:
- 2009: Openreach piloted FTTC in Muswell Hill (north London) and Whitchurch (South Glamorgan) at up to 40Mb.
- 25 January 2010: BT's Infinity "up to" 40Mbps FTTC packages were due to go live (ISPreview, 23 January 2010).
- 2010: at the start of the year more than 99% of people could get Openreach's first-generation broadband at up to 8Mbps, and by 31 March its ADSL2+ service reached 55% of the UK at up to 20Mbps.
- April 2012: Openreach doubled FTTC download speeds to up to 76Mbps.
Openreach says 5 million premises could order its fibre broadband in 2011, rising to 27.4 million in 2017. Openreach's timeline does not say how many of those premises were on FTTC and how many on full fibre, so "fibre" in those totals is not the same as full fibre.
What it explains today: for years "fibre broadband" usually meant part fibre. If an advert, an old contract or your provider's app says "fibre", it is worth checking whether that means FTTC or full fibre ("Work out which line you have", near the end of this guide, shows how). Our fibre broadband deals page lets you see what is on offer at your address.
Public money for the places the market skipped
Commercial roll-outs did not reach every home, especially in rural areas, so government has stepped in more than once.
The Superfast Broadband Programme (from 2012)
Building Digital UK's (BDUK) £2.53bn Superfast Broadband Programme extended superfast networks to 5,440,086 extra premises from 2012 (ISPreview, June 2022). It helped take superfast coverage (then 24Mbps or more; later contracts used 30Mbps) to 90% of UK premises in Phase 1 and 95% by the end of 2017 in Phase 2. Openreach says it won 19 BDUK bids in 2012 and connected the first BDUK customers in North Yorkshire in December 2012. Most of these builds used FTTC, and contracts from 2018 onwards increasingly used full fibre.
The broadband Universal Service Obligation (20 March 2020)
The broadband Universal Service Obligation (USO) went live on 20 March 2020. It gives eligible homes and businesses a legal right to request a connection of at least 10Mbps download and 1Mbps upload from BT, or from KCOM in the Hull area. It is not an automatic upgrade: you have to ask, and your address has to meet the eligibility rules (ISPreview). Our guide to the broadband Universal Service Obligation explains who qualifies today and how to apply. KCOM's own network in Hull is a story of its own, covered in our guide to KCOM's network.
Project Gigabit
The Superfast Broadband Programme has been superseded by Project Gigabit (described by ISPreview in June 2022 as a £5bn programme), which targets homes and businesses outside suppliers' own commercial plans. GOV.UK says the government expects 99% of premises to have gigabit-capable broadband by 2032. Our Project Gigabit guide explains how it reaches rural homes.
What it explains today: in remote areas the network at your address may have been built with public money, and who built it shapes your choice of providers.
Full fibre: from a new-build site in Kent to most UK homes
Full fibre, or FTTP (fibre to the premises), runs fibre all the way into your home. It arrived early but spread slowly:
- 2008: Openreach brought FTTP at up to 100Mb to a new-build site in Kent, then the fastest speed available to UK homes, it says.
- July 2012: Openreach launched a range of FTTP products.
- 2013: Openreach's first "fibre only" exchange went live in Deddington.
- 2015: Openreach planned faster speeds for 12 million addresses by the end of 2020, 10 million of them through G.fast (a faster technology for short copper lines) and 2 million through FTTP.
- 2019: KCOM says it completed the first stage of its FTTP network that year, describing Hull as "the UK's first full fibre city".
Today full fibre is built by Openreach, by Virgin Media and by a large group of independent networks often called altnets (alternative networks).
Where things stand now:
- Ofcom's Spring 2026 figures, based on January 2026 data and reported by ISPreview in May 2026, put full fibre within reach of 82% of UK homes, gigabit-capable broadband at 89% and superfast (30Mbps or more) at 98%.
- ISPreview reported on 20 October 2026 that Openreach's full fibre network covers about 24 million premises and is on track for 25 million by December 2026, with an ambition of up to 30 million by 2030.
Gigabit coverage is higher than full fibre coverage because Virgin Media's cable network reaches gigabit speeds too. To see how a typical connection compares with national figures, read our guide how your speed compares with UK figures, and for the basics of the technology see what full fibre broadband is.
The copper phone network's last chapter
The phone line that carried dial-up and then ADSL is now being retired. The milestones so far:
- 5 September 2023: Openreach's UK-wide stop sell of WLR (Wholesale Line Rental, the old analogue phone line product) took effect. Broadband provided over a WLR phone line, including classic ADSL and FTTC, can no longer be newly ordered in that form. See our Openreach stop sell guide.
- By 31 January 2027: GOV.UK says all users of the Openreach PSTN (the copper public switched telephone network) must be moved to new services, and Openreach's stop-sell page says WLR (and broadband that relies on it) is withdrawn on that date.
- After that: telephone exchanges will close over the next decade, starting with 108 by 2030. Deddington, the first fibre-only exchange in 2013, is one of the three pilot exchanges; see our guide to Openreach exchange closures.
Openreach also says today (checked October 2026) that copper (ADSL) broadband is no longer available to new customers in areas where its full fibre has been built.
In practice, landlines move to digital phone services that run over broadband. Our guide to copper retirement and what happens to part fibre covers what comes next.
What it explains today: if you are still on ADSL or a traditional phone line, change is coming either way, so it is a good moment to check what else your address can get.

What this history means for your choices today
Knowing where your home sits on this timeline helps you ask better questions and avoid paying for speed your line cannot deliver.
Work out which line you have
The four main types of fixed line are each a different chapter of the story. The speeds below are the maximums quoted by the network owners or reported by ISPreview, checked October 2026; what you get depends on your package and, for copper, your line.
Line type | How it reaches you | Quoted maximum download |
|---|---|---|
Copper (ADSL) | Copper phone line all the way from the exchange | Up to 21Mbps (Openreach) |
Part fibre (FTTC) | Fibre to the street cabinet, copper to the home | Up to 76Mbps (Openreach) |
Cable (Virgin Media) | Fibre to a Virgin cabinet, coax to the home | More than a gigabit per second (Virgin Media) |
Full fibre (FTTP) | Fibre all the way into the home | Up to 1.8Gbps on Openreach's network (ISPreview, October 2026) |
Our connection type guide goes through the checks you can make at home, and our broadband speed test shows what you are getting right now. Some Openreach lines use G.fast, and some homes skip a fixed line altogether: see our guides to whether 4G or 5G can replace fixed broadband and satellite broadband in the UK, or see what Starlink offers on our Starlink broadband deals page.
Know which network a deal uses
Many providers sell over Openreach; Virgin Media and the altnets run their own networks. The history no longer locks you in: since 12 September 2024 Ofcom's One Touch Switch process has worked between physically separate networks too (ISPreview), though Openreach says moving networks can involve extra steps such as an engineer visit. Our guides to which network your broadband is on and switching broadband providers cover the questions to ask before you sign and how a switch works.
Compare what is actually available at your postcode

UK broadband history FAQs
When did the UK get its first home broadband connection?
Openreach says the first UK home broadband connection was installed in Basildon, Essex, in April 2000. BT's first commercial ADSL lines, at 512Kbps, appeared later the same year, after one to two years of trials of both technologies.
Is 'fibre broadband' the same as full fibre?
Not necessarily. For years "fibre broadband" mostly meant FTTC, where fibre stops at the street cabinet and copper phone wire covers the last stretch; Openreach quotes up to 76Mbps for it. Full fibre (FTTP) runs fibre all the way into your home, and ISPreview reported in October 2026 that Openreach's full fibre network delivers up to 1.8Gbps (Openreach's consumer page quotes up to 1,600Mbps). Check the technology named in your contract summary.
Why can so many providers sell broadband over the same line?
Because of two changes in the 2000s. Local loop unbundling let rival operators run their own broadband over the line between your exchange and your home: unbundled lines rose from 250,000 in January 2006 to 673,000 in July 2006 (ISPreview). And Openreach, created after Ofcom's 2005 strategic review, opened for business in 2006 so every provider would have fair access to the network. That is why many brands sell over the same Openreach line and differ mainly on price, terms, equipment and service.
Why is Virgin Media a separate network from Openreach?
Because it grew from different cables. Cable broadband arrived in 2000 on the TV networks built by companies such as NTL and Telewest, which merged and said in July 2006 that they would market their services under the Virgin brand from early 2007. That network has been upgraded rather than replaced, and Virgin Media says it is on track to complete its full fibre upgrade by 2028, but it has never run over BT's phone lines. So moving to or from Virgin Media can mean different equipment and an engineer visit.
What happens to copper phone lines in January 2027?
GOV.UK says all users of the Openreach PSTN, the copper phone network, must be moved to new services by 31 January 2027, and Openreach's stop-sell page says its WLR phone line product is withdrawn on that date. Landlines move to digital services over broadband. Telephone exchanges will then close over the following decade, starting with 108 by 2030.
