What Is SoGEA Broadband & How Does It Work?

If your business broadband is bundled with a traditional phone line, change is coming. Openreach is retiring the old analogue telephone network across the UK, and SoGEA is the standard replacement for businesses that aren't yet ready to move to full fibre. Here's what SoGEA actually is, how it works, and what it means for your business.

What Does SoGEA Stand For?

SoGEA stands for Single Order Generic Ethernet Access. In plain terms, it's a broadband-only connection delivered over the same Openreach network used for standard fibre-to-the-cabinet (FTTC) broadband, but without the traditional analogue phone line running underneath it.

Historically, every UK broadband connection needed an active phone line; even businesses that never used it for calls still paid line rental for it. SoGEA removes that requirement, so you order and pay for broadband alone.

How Does SoGEA Broadband Work?

SoGEA uses the same physical infrastructure as FTTC broadband:

• A fibre optic cable runs from the local telephone exchange to your nearest street cabinet.
• A copper cable then carries the connection from that cabinet to your premises.
  
  

The difference is what travels over that copper: with FTTC, part of the line is reserved for the old analogue voice circuit; with SoGEA, the entire line is used for broadband data. There's no dial tone and no analogue phone signal; the connection is data-only from end to end.

Because calls are no longer carried over the old analogue circuit, businesses on SoGEA make and receive calls using VoIP (Voice over Internet Protocol) or Digital Voice, essentially, phone calls that run over the broadband connection itself rather than a separate wire. Any equipment still relying on the old line, such as older alarm systems, fax machines or card payment terminals, typically needs to move to an IP-based alternative as part of the switch.

Why SoGEA Matters Now: The PSTN Switch-Off

The reason SoGEA is growing in demand is the UK's PSTN (Public Switched Telephone Network) switch-off. Openreach has confirmed that the old analogue and ISDN phone network will be fully retired by 31 January 2027, after which any service still running over it, including phone lines and broadband bundled with them, will stop working.

The UK's broadband infrastructure is well down this path already. According to Ofcom's Spring 2026 Connected Nations update, full fibre broadband was available to 24.9 million UK homes, 82% of the UK's residential premises, as of January 2026, up from 78% just six months earlier, and gigabit-capable broadband (which includes full fibre and cable) reached 89% of homes. That's a rapid shift in a short space of time, and it's part of the same infrastructure transition driving the PSTN switch-off.

For business premises where full fibre isn't available yet, or where a full-fibre upgrade isn't immediately practical, SoGEA is the best product available. It's ready for the switch-off today, using infrastructure that's already in place almost everywhere FTTC is available.

What Speeds Can You Expect on SoGEA?

SoGEA runs over the same copper-to-cabinet infrastructure as standard FTTC, so speeds are comparable, typically up to 80Mbps download and 20Mbps upload, depending on the length and quality of the copper run from your cabinet. Actual speeds will vary by location.

Ofcom's regulatory framework treats this 80/20Mbps tier as the current standard regulated product on this network, replacing the older 40Mbps tier from April 2026, which reflects how far standard copper-based broadband speeds have moved on in recent years.

This is comfortably enough for day-to-day business use, cloud software, video calls, email and card payments, though businesses with heavier bandwidth needs (large file transfers, many simultaneous video calls, data-heavy applications) will generally get a better long-term return from full fibre where it's available.

What Does SoGEA Cost?

SoGEA itself isn't a separate technology with its own pricing tier so much as it is FTTC without the line rental. In practice, that means the broadband element is priced similarly to FTTC, but you no longer pay a separate monthly charge for the phone line running alongside it. For a business that has already moved calls to VoIP or mobile, that line rental was effectively being paid for a service that wasn't being used; SoGEA removes that cost.

Exact pricing depends on your provider and contract, so it's worth checking your current bill for a standalone line rental charge if you're on FTTC today; that's the cost SoGEA is designed to remove.

How Do You Switch to SoGEA?

Because SoGEA runs on the same network as FTTC, moving from an existing FTTC connection is usually straightforward:

• Your provider checks that your line is SoGEA-enabled at the exchange and cabinet.
• Where you're migrating from an existing FTTC line, the change can often be completed remotely, without an engineer visit.
• A new installation, rather than a migration, typically involves a single engineer visit and is usually completed within a working week or two, depending on the provider and location.
• You'll need a VoIP or Digital Voice solution in place for calls, and any line-dependent equipment (alarms, payment terminals) should be checked for IP compatibility before the switch.

Is SoGEA Right for Your Business?

SoGEA is best suited to businesses that need their broadband switch-off-ready now but don't yet have full fibre available, or aren't ready to commit to a full-fibre upgrade. If full fibre is available at your premises, it's generally the stronger long-term choice for speed and reliability – but where it isn't, SoGEA is a proven, low-disruption way to stay connected past January 2027 without paying for a phone line you no longer need.
