What BT Wholesale does

BT Wholesale is the wholesale division of BT Group plc, operating as the UK's largest network provider of wholesale telecommunications services to Communication Providers (CPs), channel partners, and resellers. The company does not sell directly to end customers; instead, partners resell, bundle, or white-label BT Wholesale services under their own brands, supported by the tiered Partner Plus programme with marketing development funds and dedicated account management. Its service territory is the United Kingdom, with no disclosed international footprint.

The product portfolio spans five categories: data connectivity (broadband, Ethernet, optical, SoGEA, Direct Internet Access, colocation, mobile backhaul); voice services (legacy PSTN/ISDN still in migration, plus IP Exchange, Wholesale Calls, Carrier Pre-Selection); hosted communications (Wholesale Hosted Communications, Hosted Centrex, Hosted SIP Trunking, Operator Connect for Microsoft Teams, Cisco Webex, WHC Express, Complete Switch); machine-to-machine (BT Control Centre IoT platform, Managed Dual Path, Rapid Deployable Network); and mobile solutions (Complete Mobile MVNO, Teams Phone Mobile, Multi-access Edge Compute, Wholesale Messaging). The portfolio is underpinned by BT Wholesale's own network backbone and Openreach last-mile infrastructure, with partner-facing self-service via My BT Wholesale portal, Business Zone, and The Hub.

Revenue is generated on a recurring subscription wholesale basis: CPs and resellers pay for connectivity, voice, hosted communications, mobile, and IoT services that they in turn monetize with their own end customers. Pricing is not publicly disclosed and is available to registered partners through the Service Provider and Carrier Price Lists. The business model is being actively repositioned around the January 2027 UK PSTN/ISDN switch-off, with All-IP products, Operator Connect, and UCaaS platforms serving as the principal growth vectors as partners migrate customers off legacy infrastructure. AI is embedded in specific features (conversational IVR, intelligent call routing, real-time analytics) but is not the central architectural differentiator.
