What BT does

BT Group plc is the UK's largest telecommunications operator and designated critical national infrastructure provider, headquartered in London and listed on the London Stock Exchange (LON:BT.A). The group serves more than 46 million mobile customers and 12 million fixed-line customers through its BT, EE, and Plusnet consumer brands, and supplies wholesale passive and active network access to over 600 communications providers via its Openreach infrastructure division, which passes 23 million-plus premises with full-fibre (FTTP). Enterprise and public-sector customers are served through BT Business, with a portfolio that includes the new BT Sovereign Platform (Sovereign Voice, Sovereign Cloud, and Sovereign AI) targeting regulated industries, alongside legacy IT, networking, and managed-service contracts such as the multi-year deals with BAE Systems, NIE Networks, and UK Power Networks.

The underlying technology stack combines a national fibre and 5G standalone network, a Tier-1 internet backbone, and a growing AI compute layer delivered in partnership with Nscale (50MW at Loughton). Revenue is generated through a mix of recurring consumer subscriptions (broadband, mobile, pay-TV), enterprise multi-year managed-service contracts, wholesale line rental and passive access charges from Openreach, and emerging sovereign-AI and cybersecurity services — the latter built on BT's own telemetry from blocking roughly 4 million cyber attacks per day. The economics are capital-intensive: BT is committed to approximately £40bn of network investment from 2020 to 2030 with a further £15bn signalled, financed through a combination of operating cash flow, asset sales, and equity (notably a 24.5% stake acquired by Bharti Enterprises).

The business model is currently being re-engineered under a restructuring programme targeting £3.7bn of cost savings and a workforce reduction from roughly 130,000 to around 75,000 by 2030, with AI and automation expected to absorb a significant share of the displaced roles. Strategic positioning is shifting away from declining legacy fixed voice and low-margin wholesale towards sovereign enterprise technology, cybersecurity, and AI infrastructure — supported by partnerships with Anthropic (Project Glasswing), NVIDIA, Ericsson, and Samsung, and a 6G AI-RAN coalition. Reported FY26 adjusted revenue is approximately £19.7bn, with FY27 guided to £19.0–19.5bn, indicating a top-line that is contracting in legacy segments while margins and free cash flow are being expanded through restructuring.

Scale indicators13 records

Recent moves9 records

Expansion highlights7 records

Direct peers

• CityFibre: UK wholesale fibre challenger building alternative full-fibre networks; competes directly with Openreach at the wholesale layer and is a key driver of BT's recent broadband losses.
• Vodafone Group: UK's other major converged fixed-mobile operator with overlapping broadband, mobile and enterprise offerings. Most directly comparable peer across consumer, business and wholesale network layers in the UK market.
• Virgin Media O2: Joint venture between Liberty Global and Telefonica, combining Virgin Media's cable/fibre footprint with O2's mobile network. Directly competes with BT/EE in UK broadband, mobile and pay-TV.
• Sky (Comcast): Major UK broadband, pay-TV and streaming provider now under Comcast ownership. Competes head-on with BT Consumer in broadband bundles and TV, and increasingly in mobile via Sky Mobile.
• TalkTalk Telecom Group: UK-focused value broadband and TV provider selling over Openreach's wholesale network. Closely comparable on consumer broadband pricing and customer-segment dynamics.
• Three UK (CK Hutchison): UK mobile network operator and direct competitor to EE in 5G/4G services. Compares on mobile ARPU, coverage rollout and enterprise mobile propositions.

Emerging players

• Hyperoptic: UK altnet focused on gigabit fibre to multi-dwelling units and select urban areas. Emerging competitor cherry-picking high-ARPU urban footprints away from Openreach.
• Community Fibre: London-focused altnet rapidly expanding full-fibre footprint; emblematic of the altnet cohort pressuring BT's broadband share and ARPU in urban markets.
• Nexfibre: Wholesale fibre joint venture between Liberty Global, Telefonica and InfraVia, currently pursuing a CMA-reviewed merger with Netomnia that would create Openreach's largest wholesale fibre rival in the UK.

Broad incumbents

• Deutsche Telekom: European telecom incumbent owning T-Mobile and operating integrated fixed-mobile businesses across Europe. Comparable on converged portfolio, fibre+5G capex programme, and sovereign infrastructure positioning at scale.
