Ofcom allows Openreach copper network retirement price hikes by 2029

The regulatory shift accelerates the transition to full-fibre by making legacy copper maintenance economically unattractive for providers. For the streaming industry, this migration ensures a more stable technical foundation for high-bitrate 4K and 8K content delivery as copper-related dropouts and latency issues are phased out. By lowering the threshold for price adjustments from 100% to 90% coverage, Ofcom is effectively forcing the hand of retail ISPs to migrate their remaining legacy subscriber bases. Watch for Openreach to increase its decommissioning pace in urban exchange areas as the 2029 deadline approaches to maximize wholesale revenue efficiency.

Openreach's full-fibre buildout has accelerated sharply in recent months, with the company reaching 10 million premises passed by its FTTP network in early 2025. Openreach confirmed it had passed 10 million UK premises with full fibre in January 2025, a milestone that put it ahead of its own internal targets and intensified pressure on rival alt-nets such as CityFibre and Virgin Media O2 to match coverage in competitive exchange areas. The 90% ultrafast coverage threshold that Ofcom has now formalized for price adjustments aligns with Openreach's stated goal of reaching 25 million premises by December 2026, meaning a large number of exchange areas will qualify for copper price changes well before the April 2029 start date.

The regulatory framework around copper retirement has been evolving across multiple jurisdictions, giving Ofcom's decision broader international context. Ofcom published its Wholesale Fixed Telecoms Market Review in March 2025, setting out the conditions under which Openreach can withdraw legacy products and adjust pricing in areas deemed competitively served by fibre. Meanwhile, BT Group announced in February 2025 that it would bring forward its copper switch-off target to January 2027, compressing the timeline for ISPs to complete their migration planning. The price adjustment mechanism approved this week gives Openreach a commercial lever to push remaining copper customers toward fibre before the physical network is decommissioned.

For streaming platforms and content delivery networks, the copper-to-fibre transition carries measurable implications for network performance. Ofcom's Connected Nations 2025 report found that full-fibre connections delivered average download speeds of 910 Mbps, compared to 67 Mbps on legacy copper-based VDSL connections, a gap that directly affects the reliability of 4K HDR streams requiring sustained throughput above 25 Mbps. Netflix's ISP Speed Index for the UK showed that fibre-connected ISPs consistently ranked above 4.5 Mbps for streaming performance, while copper-dependent providers lagged below 3.5 Mbps during peak hours. The price signals Ofcom has now authorized should accelerate subscriber migration in the exchange areas where streaming demand is highest, reducing the addressable base of copper-connected households that experience buffering and quality degradation.
