Is Your Business Ready for the BT Switch Off?
The Clock Has Already Run Out on Waiting
We're now in 2026 — less than a year from the deadline. The businesses that act now will migrate smoothly and on their terms. Everyone else will face a scramble.
Your Costs Are Already Rising — Just to Stand Still
Maintaining legacy PSTN and ISDN lines is becoming dramatically more expensive as the network ages and BT reduces investment in it. Many businesses are seeing their line rental and maintenance costs double — a 100%+ increase — just to keep systems running as they are today. You're paying more for an infrastructure that is guaranteed to switch off.
Capacity Crunch Is Here Now
With millions of businesses still needing to migrate, engineers, hardware, and installation slots are already being booked up. Reputable providers are filling their calendars fast — and as demand outstrips supply, prices for late movers will only increase further.
The Network Is Already Failing
BT reported a 45% increase in significant PSTN incidents in 2024 alone. Sticking with legacy lines in 2026 means accepting growing unreliability — more outages, more downtime, and more disruption to your business operations.
Hidden Dependencies Take Months to Uncover
Most businesses don't realise how many systems rely on copper lines until they do a proper audit. Identifying everything, planning the migration, testing, and going live takes time. Starting now gives you control. Leaving it until Q4 2026 means rushing — and rushed migrations cause downtime.
A Last-Minute Switch Means Real Business Risk
A rushed migration with no testing window risks days of lost connectivity, failed card payments, offline alarms, and missed calls. For many SMEs, even a single day of downtime has lasting commercial and reputational consequences.
