Is Your Business PSTN Switch-Off Ready?
PSTN — the UK's traditional copper-wire phone network — is being switched off permanently on 31st January 2027. If your business still uses analogue lines, ISDN, or any services that run over a traditional phone line, you need to act before that date.
The good news: if you act now, the migration is straightforward. The risk is in waiting too long, as 2027 approaches, demand for migration support will increase and your options will narrow.
Many think this only applies to their phones or won't affect their other services — but this switch-off impacts more than you think.
Business phone lines and handsets
ISDN lines and Featurelines
Broadband connections running over copper lines
Fax machines and lift emergency lines
Card payment machines (EPOS)
Door entry and intercom systems
Alarm and security systems

Frequently Asked Questions
On 31 January 2027, Openreach permanently retires the UK's analogue PSTN and ISDN network. Any service that runs over a traditional copper phone line, including business phones, ISDN lines, and some broadband connections — will stop working if it hasn't been migrated to a digital alternative. You need to act before this date.
Your number itself is not lost automatically, but if your line stops working and you haven't ported your number to a digital provider, you could lose it. TTNC handles number porting end-to-end as part of Switch-Off Ready. Your number comes with you.
You port your number to a digital provider before the switch-off. TTNC manages the porting process for you, it's part of the Switch-Off Ready migration. In most cases, porting takes a few working days and your service stays live throughout.
Switch-Off Ready is TTNC's comprehensive PSTN migration package. It includes number porting, a dedicated engineer to manage your migration, free installation (first 100 customers), and a 24-month price lock. It's designed for UK businesses that want their migration handled properly.
For most small businesses, the full migration takes 2–4 weeks from initial audit to going live. Businesses with more complex setups, multiple sites, legacy systems, or third-party integrations, may take longer. We'll give you an accurate timeline after the free assessment.
We'd still recommend booking your free assessment now. Your migration can be planned and ready to execute as soon as your contract allows, and in many cases we can migrate you at a fixed point that avoids any overlap in costs. The worst outcome is leaving it too late.
Not necessarily. Many modern IP desk phones work with VoIP (digital phone) systems without replacement. We'll check your existing equipment during the audit and tell you exactly what, if anything, needs changing. We won't recommend hardware you don't need.
Yes. TTNC is Ofcom regulated and ISO 9001 accredited. We're also a member of the Comms Council UK and publish a Code of Practice. Our network runs on BT Wholesale and PXC direct interconnects.
