what businesses ask about the switch-off

The nationwide deadline is 31 January 2027, when the UK’s PSTN and ISDN networks are formally retired. The rollout is phased, though, so individual exchanges are being switched over much earlier. The safe assumption is that your line could be affected any time in the months leading up to the deadline.
No. Your existing numbers port across to the new cloud system, so what your customers dial doesn’t change. Landlines, geographic, non-geographic and freephone are all supported. Most porting completes in around 10 to 15 working days and we handle the paperwork end to end.
Your lines stop working the day your local exchange is switched off. Phones go silent, inbound calls fail, and anything that piggybacks on the line, alarms, payment terminals, lift phones, door entry, stops working too. Moving now avoids the last-minute rush as the deadline approaches.
For most small and mid-sized teams, the new system is live within a week of saying yes. Number porting from the old provider then runs in parallel, usually completing in 10 to 15 working days. Larger or multi-site businesses take a little longer and we plan the rollout in stages.
It shouldn’t be. We provision and test the new platform alongside your existing lines, ship any handsets pre-configured, and only flip the switch when everything is ready. Your team keeps taking calls on the old system right up until cut-over, so there’s no quiet day in between.
