Free landline number for UK businesses

A free landline number from Silux Call is a UK geographic number (a virtual landline) delivered over the internet at £0 during the 14-day trial — it behaves like a traditional landline but needs no phone line, line rental or hardware. Free for 14 days (1 user, 30 outbound minutes). Heavier outbound calling moves you to Pay-as-you-go at £0.02/min or a paid plan — still with no line rental.

One free UK landline-style geographic number (e.g. 020, 0161, 0121); Works on your existing phone, laptop or desk phone; Survives the 2027 PSTN switch-off (it is already VoIP); Free voicemail-to-email and call divert; No line rental, no copper line, no install.

No. You can start the Silux Call free trial and free trials without a card. You only add payment details if you choose to upgrade to a paid plan.

Yes. Silux Call runs entirely over IP, so it is unaffected by the 31 January 2027 PSTN switch-off — and every account includes a free WLR2 migration audit.
