Openreach Upgrades The Shard as Copper Switch-Off Approaches

Why It Matters

The imminent PSTN switch‑off forces UK businesses to adopt full‑fibre, impacting continuity, security and operational costs, while Openreach’s pricing strategy creates a strong financial incentive to act now.

Key Takeaways

• 3,000 London buildings risk losing services after switch‑off.
• PSTN shutdown set for January 2027, ten months away.
• Legacy line prices rise 20% now, 40% later.
• Openreach uses The Shard upgrade as migration showcase.
• Digital Voice rollout delayed by telecare concerns, now resolved.

Pulse Analysis

The United Kingdom’s public switched telephone network (PSTN) is slated for permanent shutdown at the end of January 2027, giving operators less than ten months to migrate remaining users to all‑digital services. After an initial deadline of 2025 was extended by 13 months to protect vulnerable telecare customers, regulators have now cleared the path for a full fibre transition. Roughly 2.8 million PSTN lines remain active, half of them serving businesses, and the loss of copper could interrupt phone lines, alarm systems and remote monitoring if not replaced in time.

Openreach is leveraging high‑profile upgrades such as the recent conversion of The Shard to showcase a swift, disruption‑free migration. Engineers added full‑fibre infrastructure to the skyscraper’s existing secure Ethernet in a few hours, demonstrating that similar multi‑tenant buildings can be upgraded without tenant impact. At the same time, the telco has introduced steep price hikes for legacy copper services—20 % in April, an additional 40 % in July, and a final 40 % increase in October—effectively doubling the cost of outdated lines and pressuring reluctant customers to act.

The aggressive timeline and pricing signal a broader industry shift toward smart‑building connectivity and cloud‑based communications. Service providers that fail to guide their enterprise clients through the transition risk losing revenue and facing regulatory scrutiny over business‑continuity failures. For landlords and corporate tenants, the upgrade offers more than just voice replacement; it enables IoT sensors, enhanced security, and higher‑capacity broadband essential for post‑pandemic work models. As the switch‑off approaches, firms that proactively adopt full‑fibre will secure operational resilience and position themselves competitively in a digitised market.
