Business phone systems in Grantham
Silux Call provides hosted VoIP, a cloud PBX and an AI receptionist to businesses across Grantham and the wider Lincolnshire. A south-Lincolnshire food and logistics economy, and local firms get 01476 area-code numbers, 24/7 UK support, and a clear path to the 31 January 2027 PSTN switch-off — Openreach has already started stop-sell across Grantham-area exchanges. Pricing is GBP-only, from a 14-day free trial to Pay-as-you-go at £0.02/min, with no long-term contract. Grantham’s food production, logistics, engineering employers are the typical customer.

FAQs — Grantham
Can I keep my Grantham phone number?
Yes. We port Lincolnshire landline numbers free on every plan. Send us a recent bill and a signed letter of authority; your existing 01476 number moves across without losing a call, and your old line keeps working until it completes.
When does the PSTN switch off for Grantham?
BT Openreach is retiring the UK PSTN (WLR2) nationally on 31 January 2027. Many Openreach exchanges serving Grantham are already on stop-sell, so analogue lines can no longer be ordered there — migrating early avoids a rushed cut-over.
Is Silux Call regulated in the UK?
Silux Call is operated by Silux Control UK Ltd T/A Silux Call, registered in England & Wales, and UK business telephony is regulated by Ofcom. That framework is what sets your right to keep your number when you switch, the rules on emergency 999/112 access, and the complaints route we publish in our Complaints Code of Practice. Silux Call follows Ofcom's General Conditions of Entitlement for Grantham customers as for every other UK location.
Can I call 999 from a VoIP phone in Grantham?
Yes. Emergency calls to 999 and 112 work from Silux Call, and we hold the Grantham service address you register so emergency operators receive a location. Because a VoIP line depends on power and broadband, Ofcom expects providers to be clear about that: keep a charged mobile as a backup for a power cut, exactly as you would with any internet-based phone service.
What does business VoIP cost in Grantham?
Silux Call has a 14-day free trial, Pay-as-you-go at £0.02/min UK landline, and paid plans from £4.75/user/month, all billed in GBP with no contract. There is no premium for Grantham or any other UK location.
Do I need new phones for my Grantham office?
No. Silux Call runs on the mobile, desktop and web softphone, so existing computers and smartphones work immediately. IP desk phones are optional and provisioned automatically if you want them.
Can Grantham businesses get a local 01476 number?
Yes. New 01476 area-code DDIs are provisioned in seconds, or you can port your existing Grantham number for free on Plus and above.
Can I get a free phone number in Grantham?
Yes. Silux Call's 14-day free trial includes one free UK number — a local 01476 Grantham number or an 03 number — with free voicemail-to-email and call divert, no card required. You get 30 outbound minutes a month free; add more numbers from £1/month.
