London is home to a strong mix of professional services, agencies, and SME head offices across every sector, and like the rest of the UK, every business here is on the clock for the 2027 PSTN switch-off. Here's what business VoIP looks like specifically for London.
Why London businesses are switching to VoIP
London businesses have no shortage of VoIP providers to choose from — the difference with VoIPninjas is straightforward pricing, no long contracts, and support from a team that answers the phone rather than a ticketing queue.
Local relevance: the PSTN switch-off in Greater London
Openreach is retiring the traditional analogue phone network by January 2027, exchange by exchange. Businesses around London still relying on ISDN or PSTN lines — including alarm systems, payment terminals and fax machines tied to the old network — need a migration plan before their local exchange stops-sell date. See Openreach's PSTN switch-off timeline for the current schedule.
What VoIPninjas offers London businesses
Cloud VoIP means no on-site hardware to maintain and no dependency on the ageing copper network. number porting keeps your existing local number, and setup is typically live within a week of signing up.
Multi-site and remote-first London businesses
Many London SMEs run distributed or hybrid teams. See our guides to VoIP for multi-site businesses and VoIP for remote workers for the specific setup considerations.
