Getting Broadband Without a Phone Line: SOGEA and FTTP Explained

Broadband without the old phone line

For many years broadband in the UK was sold on top of an analogue phone line, and customers paid line rental whether or not they made calls. That arrangement is being unwound. Openreach now offers products that deliver broadband without an active analogue voice line, which is why line rental as a separate charge is disappearing from most packages. The two products at the centre of this change are SOGEA and FTTP, and understanding the difference helps explain what you gain and what you give up.

The shift is being driven by the retirement of the legacy telephone network. According to Openreach's published timeline, the analogue PSTN is being switched off through the all-IP migration completing in 2027, so there is less reason to keep selling broadband as an add-on to a copper voice line. Instead, the broadband connection becomes the primary service, and any telephone calling rides on top of it digitally. This reverses the old relationship between line and broadband. Under the old model the voice line was the foundation and broadband was the overlay; under SOGEA and FTTP the broadband is the foundation and voice, if it is wanted at all, becomes a software service carried as data over that connection.

What SOGEA is and how it works

SOGEA stands for Single Order Generic Ethernet Access. It uses the same physical connection that carried older broadband, often the copper from the cabinet to the home combined with fibre back to the exchange, but it removes the active analogue telephone service. The result is a single broadband product ordered on its own, without a voice line and without separate line rental. Speeds are broadly similar to the fibre-to-the-cabinet broadband it replaces, because the underlying physical path is the same. The difference is administrative as much as physical: where the old arrangement required a voice line order and a broadband order stacked together, SOGEA is a single order for broadband alone, which is exactly why there is no separate line rental line for it to carry.

For most households the practical change with SOGEA is simply that the bill no longer carries a line rental line item, and there is no analogue dial tone on the socket. If you still want a home phone, your provider supplies it as a digital voice service over the broadband connection. SOGEA is often the stepping-stone product in areas that do not yet have full fibre, keeping the existing wiring while ending the old voice-line dependency. Because it reuses the copper from the cabinet to the home, SOGEA can be provisioned without the civil engineering work that pulling new fibre to the property requires, which is why it has been the practical route to ending line rental in places where the full-fibre build has not yet arrived. When fibre to the premises does reach the street later, a SOGEA household can usually be upgraded to FTTP.

Broadband without phone line options

The table below compares the main ways to take broadband without a traditional analogue phone line. It focuses on the line, the calling option and what happens to an existing number.

What FTTP changes and the end of line rental

FTTP, fibre to the premises, runs a full-fibre connection all the way to the home rather than stopping at a street cabinet. Because it is a fibre service from end to end, it carries no traditional analogue phone line and never did. Any telephone calling on an FTTP connection is digital voice delivered over the fibre. FTTP generally supports higher and more consistent speeds than the copper-based services it replaces, which is the main reason it is being rolled out across the country. A fibre strand is not subject to the distance-related signal loss that limits copper, so the speed an FTTP household receives is far less dependent on how far the property sits from the cabinet or exchange, which removes one of the main causes of variable performance on the older copper services.

Both SOGEA and FTTP mark the end of separate line rental for most customers. Where the old model bundled an analogue line you were obliged to pay for, these products price broadband as the core service. If you do not need a home phone, you simply take the broadband and pay nothing for a voice line. If you do want a home phone, you add a digital voice service, but it is now an option on top of broadband rather than the foundation underneath it. The installation differs between the two: SOGEA typically reuses the wiring already present, whereas FTTP usually involves an engineer bringing a new fibre into the property and fitting an optical termination point on the wall, into which the router connects. That one-off installation step is the visible sign that the copper era has ended for that address.

What you lose and how to keep a phone number

The main thing you lose by taking broadband only is the home telephone itself. Without an analogue line and without a digital voice add-on, the broadband connection does not provide a dial tone or a number. For households that have moved entirely to mobiles this is no loss at all. For those who still want a home phone, the answer is a VoIP or digital voice service, which delivers calling over the broadband connection. The handset experience is largely unchanged: an ordinary phone plugs into the router or an adapter, and dialling works as before, with the call converted into data and carried over the internet rather than down a copper voice path.

Keeping an existing phone number is usually possible by porting it to the new digital voice or VoIP service when you switch, rather than letting it lapse. It is worth arranging the port as part of the order so the number carries across cleanly. Remember that digital voice depends on mains power, so a battery backup or alternative is needed for power-cut resilience, and Ofcom requires providers to support emergency calling for vulnerable customers during an outage. Ofcom's guidance on moving landlines to digital technology sets out the protections providers must offer, particularly for customers who rely on their landline for safety or who have poor mobile coverage, and anyone in that position should flag it to their provider before the switch so that a suitable resilience solution is fitted.

Resilience, telecare and who should plan ahead

The dependence on mains power is the single most important practical difference between the old analogue line and a digital voice service, and it deserves attention beyond a passing mention. The legacy copper line was powered from the exchange, so a basic corded phone kept working in a power cut even when the rest of the house went dark. A router-based digital voice service stops if the electricity stops, unless a backup power source keeps the router and any necessary equipment running. For most households this is a minor inconvenience covered by a mobile phone, but for some it is a genuine safety issue.

The households that most need to plan ahead are those that use the landline for telecare or personal alarm systems, those with no reliable mobile signal, and those who depend on a working phone for medical reasons. Many telecare alarm units were designed for the analogue network, and some need checking or replacing to work correctly over digital voice, so it is sensible to confirm compatibility with the alarm provider before migrating. Ofcom expects communications providers to identify customers who may be at risk and to offer a solution, such as a battery backup unit that supports calls to the emergency services for a period during an outage. Raising these needs early, rather than discovering a problem during a power cut, is the dependable approach, and it is the one piece of homework that broadband-only and digital voice customers should not skip.

Frequently Asked Questions

Can I get broadband without a phone line?

Yes. Products such as SOGEA and FTTP deliver broadband without an active analogue phone line, and most providers now sell broadband without separate line rental. If you want a home phone you add a digital voice or VoIP service over the broadband, but it is optional rather than required, and a household happy to rely on mobiles can take broadband alone.

What is SOGEA?

SOGEA stands for Single Order Generic Ethernet Access. It is an Openreach product that provides broadband over the existing copper-and-fibre path without an active analogue telephone line, removing the old line rental charge. Speeds are similar to the fibre-to-the-cabinet broadband it replaces, and any phone calling is delivered digitally over the connection.

Do I still pay line rental with FTTP?

No. FTTP is a full-fibre service with no traditional analogue phone line, so there is no separate line rental to pay. You pay for the broadband, and if you want a home phone you add a digital voice service. This reflects the wider end of standalone line rental as the analogue network is retired through the all-IP migration.

Can I keep my phone number with broadband-only?

You can usually keep your number by porting it to a digital voice or VoIP service at the time you switch. A pure broadband-only connection with no voice service does not carry a number on its own. Arranging the port as part of the order helps the number transfer across without a gap, so it should be raised when the order is placed rather than afterwards.

What is the difference between SOGEA and FTTP?

SOGEA uses the existing copper-and-fibre path to the cabinet and removes the analogue voice line, while FTTP runs full fibre all the way to the premises. FTTP generally offers higher and more consistent speeds because fibre does not suffer the distance-related signal loss of copper. Both end separate line rental and deliver any phone calling digitally over the broadband rather than over the legacy network.
