SoGEA Broadband: Business Internet Without a Phone Line
SoGEA delivers broadband over a single line with no phone service attached — removing £10–£15/month of line rental you no longer need. With the PSTN switch-off landing on 31 January 2027 and around 2.4 million UK businesses still on analogue lines, SoGEA is how FTTC-area businesses get switch-off ready.
Quick answer: what is SoGEA?
SoGEA (Single Order Generic Ethernet Access) is broadband delivered over the Openreach network without an underlying phone line — the same up-to-80/20 Mbps speeds as FTTC, minus the £10–£15/month line rental for a phone service the PSTN switch-off is retiring anyway. Over a 36-month term that's £360–£540 saved. Voice moves to hosted VoIP (typically £5.95–£20 per user/month), which is the point: after 31 January 2027, analogue lines stop working.
Check availability for your postcodeWhy does SoGEA exist?
Historically, broadband over copper required an active phone line underneath it — you paid line rental whether or not anyone used the phone. SoGEA breaks that link: one order, one line, broadband only. The timing matters because the analogue phone network it replaced is being retired: the PSTN and ISDN switch-off completes on 31 January 2027, and roughly 2.4 million UK businesses are still on analogue services (with around a third of large corporations still running some analogue lines — Aircall, 2025). Everyone on FTTC-with-phone-line eventually needs to make this move.
What speeds does SoGEA deliver?
SoGEA uses the same fibre-to-the-cabinet infrastructure as FTTC: up to 80Mbps down and 20Mbps up, with real-world speeds depending on your distance from the cabinet. It's the right product where full fibre hasn't arrived yet — where FTTP is available (100Mbps–1Gbps+), FTTP is almost always the better order for the same reasons at similar money.
What happens to your phone numbers?
Voice moves to hosted VoIP running over the broadband — typically £5.95–£20 per user/month, with your existing numbers ported across (allow 5–15 working days for porting). Done properly, the combined SoGEA + VoIP bill is usually lower than the old broadband + line rental + phone system stack, and the phones gain mobile apps, Teams integration and call routing the analogue line never had. See business VoIP for how AMVIA runs the voice side.
The bottom line for the 2027 switch-off
Don't wait for the deadline: engineer availability tightens as it approaches, and a rushed migration is how numbers get lost. The sequence that works: check what your postcode supports (SoGEA or FTTP), order the data line, port the numbers to VoIP, then cease the analogue services. AMVIA manages that sequence end to end — see the full PSTN switch-off guide for the timeline and planning detail.
Why Businesses Move to SoGEA
Line Rental Gone
Removes £10–£15/month of phone line rental — £360–£540 over a 36-month term — for a service the switch-off retires anyway.
Switch-Off Ready
The PSTN and ISDN switch off on 31 January 2027. SoGEA plus hosted VoIP is the standard migration path for FTTC-area businesses.
Better Phones, Not Just Cheaper
Hosted VoIP (typically £5.95–£20/user/month) adds mobile apps, Teams integration and call routing analogue lines never had.
Numbers Move With You
Existing numbers port to VoIP in 5–15 working days — planned properly, callers never notice the change.
Your SoGEA Migration Checklist
The sequence that gets you off analogue without losing numbers or service.
Check FTTP first
If full fibre is available at your postcode, order that instead — same migration, faster product.
Audit every analogue service
Phone lines, alarms, door entry, card terminals, fax — anything on a phone line needs a switch-off plan, not just the phones.
Choose the VoIP platform before ceasing lines
Port numbers to the new platform while the old lines still work — never cease first.
Allow for porting time
Number porting takes 5–15 working days. Sequence the cutover so there's no gap.
Right-size the connection
SoGEA's 80/20 suits smaller teams; heavy VoIP and cloud use may justify FTTP or a leased line with guaranteed bandwidth.
SoGEA FAQs
Single Order Generic Ethernet Access — broadband delivered over the Openreach network with no phone service attached. One order, one line, data only. You get the same up-to-80/20 Mbps speeds as FTTC without paying £10–£15/month line rental for an analogue phone service.
Removing the line rental typically saves £10–£15 per month — £360–£540 over a standard 36-month term. Voice moves to hosted VoIP at £5.95–£20 per user/month, and the combined bill is usually lower than the old broadband-plus-line-rental-plus-phone-system stack.
Your numbers port to a hosted VoIP service running over the broadband — allow 5–15 working days for porting. The critical rule: port the numbers before ceasing the old lines, never after, so there's no gap and no lost numbers.
Yes — the PSTN and ISDN networks switch off on 31 January 2027, and roughly 2.4 million UK businesses are still on analogue services. Anything running on an analogue line (phones, alarms, card terminals) stops working after the switch-off. Migrating early avoids the engineer bottleneck as the deadline approaches.
If FTTP is available at your address, order FTTP — full fibre at 100Mbps–1Gbps+ beats SoGEA's up-to-80Mbps copper-assisted speeds for similar money. SoGEA is the right answer where full fibre hasn't arrived yet. Either way the phone-line migration is the same.
