What Openreach Ltd does

Openreach Ltd is the UK's primary wholesale fixed-line telecommunications infrastructure provider, operating the access network that connects UK homes and businesses to retail broadband, voice, and data services. A wholly owned subsidiary of BT Group plc (LSE: BT.L), Openreach was established as a legally separate entity to provide equivalent access to all communications providers on regulated, non-discriminatory terms. Its network spans 192+ million kilometres of cable and reaches approximately 96.59% of UK premises, currently serving 19 million connected premises with a stated target of 25 million Full Fibre (FTTP) premises by the end of 2026.

The company operates a wholesale-only business model: Openreach does not sell broadband or voice directly to end users. Instead, it provides regulated access products — including copper (WLR/PSTN), fibre-to-the-cabinet (FTTC/VDSL), and gigabit-capable Full Fibre (FTTP, currently up to 1,600 Mbps) — to more than 650 communications providers, who in turn retail services to consumers and businesses. Key customer segments include the major UK ISPs (BT Consumer, Sky, TalkTalk, Vodafone, EE, Plusnet, Virgin Media O2) and a long tail of altnets, B2B resellers, and MVNO-fibre bundles. Over £17 billion has been invested in the network over the past decade, and the company employs more than 25,000 engineers supported by a 27,000+ vehicle fleet. The legacy PSTN network is being retired in favour of All IP by January 2027, representing the largest service-migration programme in the company's history.

Revenue is not separately disclosed by BT Group, but the segment's scale, headcount, and premise footprint imply multi-billion-pound annual external revenue, regulated under Ofcom's Wholesale Fixed Telecoms Market Review. Pricing, product roadmap, and capital deployment are consequently shaped by regulatory determinations and stakeholder consultation as much as by competitive dynamics. The competitive landscape is evolving: alternative fibre operators (CityFibre, nexfibre, Hyperoptic, Community Fibre) are overbuilding in select urban areas, but Openreach remains the only operator with a national, near-universal footprint, preserving its position as the default wholesale on-ramp for UK fixed connectivity.

Scale indicators8 records

Recent moves7 records

Expansion highlights4 records

Direct peers

• CityFibre: UK wholesale FTTP operator building competing full-fibre networks and selling to ISPs on a similar wholesale model, making it Openreach's closest head-to-head rival for communications provider customers.
• Colt Technology Services: Pan-European fibre operator providing Ethernet, wavelengths and on-demand connectivity to enterprises and carriers; comparable on enterprise-grade Ethernet products and network backbone services.
• Virgin Media O2: UK cable and fibre network operator providing broadband infrastructure to millions of premises; competes directly with Openreach's footprint at the wholesale and retail level, and is also a customer via PIA.

Others

• TalkTalk: Major UK communications provider that buys wholesale access from Openreach but also operates its own FTTP build; represents the customer side of Openreach's wholesale model while increasingly becoming a competitor.
• Cellnex Telecom: European telecom infrastructure operator owning passive mobile and fibre assets; comparable as an infrastructure-only wholesale model with regulatory-driven open access, similar to Openreach's BT Undertakings framework.
• Sky Broadband (Sky UK): One of Openreach's largest communications provider customers; comparable as a major UK retail broadband provider whose network strategy depends on Openreach wholesale inputs.

Emerging players

• Hyperoptic: UK altnet focused on FTTP rollouts in MDUs and dense urban areas; competes for the same communications provider channels and uses Openreach's PIA ducts to extend its own footprint.

Regional players

• Community Fibre: London-focused FTTP altnet building full-fibre to residential premises and selling wholesale to CPs; a regional peer that demonstrates the altnet competitive threat to Openreach's urban footprint.

Broad incumbents

• Zayo Group: Large-scale fibre infrastructure operator providing wholesale wavelengths, dark fibre and Ethernet across Europe and North America; comparable on long-haul fibre and enterprise Ethernet services.
• Lumen Technologies: Global enterprise fibre and network services provider with significant UK and European backbone assets; comparable on Ethernet, optical spectrum and wholesale enterprise connectivity offerings.
