What Stream Networks does

Stream Networks is an independent UK business telecommunications and managed services provider, headquartered in Newbury, Berkshire, founded in 2007 and operating as a privately held limited company. The company delivers managed connectivity (FTTC/FTTP broadband, Fibre Ethernet leased lines from 100Mbps to 10Gbps, SD-WAN, MPLS/VPLS, Dark Fibre and 4G/5G mobile broadband), cloud services (ISO27001/PCI-DSS accredited private cloud, the vNebula self-service virtual data centre, Office 365 resale, and Veeam-backed cloud backup), unified communications (VoiceLogic cloud PBX, hosted telephony, Microsoft Teams Direct Routing, SIP trunks, 3CX and RingCentral), IoT connectivity (multi-network SIMs across EE/Vodafone/O2/Three, LPWAN/LoRaWAN, NB-IoT and CAT-M), and cybersecurity (CyberShield, DDoS scrubbing, managed firewalls, penetration testing). Its infrastructure is built on a purpose-built Juniper Software Defined fibre network with multi-homed transit, peering, and aggregation across Openreach, CityFibre, Virgin Media and ITS, with all managed services delivered through the proprietary Cascade customer portal and supported 24x7x365 from a UK-based Network Operations Centre.

The revenue model is overwhelmingly subscription-based and recurring: monthly broadband contracts (£22.99–£66.50), multi-year leased lines (£167–£995+), per-user cloud telephony (£15–£20), tiered IoT SIM pricing (£0.35–£2.50 plus usage), and per-seat Office 365 subscriptions. Managed infrastructure and business energy procurement provide additional managed-services and fee-based revenue. Go-to-market is sales-led, combining a UK direct sales team for enterprise and mid-market deals, the Cascade portal for SMB self-service and quoting, a wholesale portal (stream.net.uk) for ISP partners, and a formal channel partner program for resellers and integrators. Customer verticals include public sector, education (schools, academies, universities), legal, financial services, charities, and software developers, with named logos spanning Somerset NHS Foundation Trust, Gardner Leader Solicitors, Newbury Academy Trust, Bremont Watches, Tchibo Coffee, Roland Mouret, Queen Margaret University, and Kensington and Chelsea Council.

The company is independently owned, with no parent company, no disclosed external funding rounds, and no public listing. Recent strategic activity includes the 2025 acquisition of LCC Communications, partnerships with CityFibre and Juniper Networks, expansion of SD-WAN and IoT product lines, and a dedicated PSTN switch-off migration practice ahead of the January 2027 UK deadline. Certifications include ISO27001, ISO9001, ISO14001, BS25999, PCI-DSS, G-Cloud, and IGGSOC, providing eligibility for public sector and regulated workloads.
