The UK communications regulator, Ofcom, has introduced a new five-year regulatory framework designed to accelerate the nationwide transition to full fibre broadband. The measures specifically target Openreach, the infrastructure division of BT, by tightening rules on its pricing and service standards to encourage greater consumer uptake of faster internet services as the physical network build nears completion.
Full fibre availability in the UK has expanded dramatically, now reaching 78 percent of premises, a significant increase from just six percent in 2018. Coverage is projected to extend to 29 million properties by 2027. However, adoption rates have not kept pace with this infrastructure rollout; more than half of premises that can access full fibre have not yet upgraded. Ofcom argues that higher connection rates are essential to unlock national productivity gains and support data-intensive future technologies, including artificial intelligence and 5G networks, which rely on dense fibre backhaul.
Key Regulatory Changes
The new regulatory package extends wholesale price caps to broadband products with speeds up to 80Mbit/s. It also imposes stricter oversight on Openreach’s discounting practices to prevent potentially anti-competitive behaviour. In areas with less competition, Ofcom is introducing tougher minimum service standards for Openreach.
A significant shift in policy is the reduced regulatory focus on the legacy copper telephone network. This change gives Openreach more flexibility to migrate customers from copper-based services to new fibre optic connections. Ofcom stated that the overall package aims to balance the need for continued private investment in networks with ensuring fair competition as the market matures.
Market Context and Future Review
While approximately 75 percent of UK premises are now served by at least two competing broadband networks, Ofcom acknowledges that Openreach retains significant market power due to its extensive existing infrastructure. Competitors will retain regulated access to Openreach’s physical network assets, such as its ducts and telegraph poles, to build their own networks.
Natalie Black, Ofcom’s Group Director for Infrastructure and Connectivity, described the new framework as “a major milestone on the road to a better connected, more productive Britain.” The regulator has signalled that future deregulation is possible if sustainable, widespread competition emerges in the fibre broadband market.
Ofcom plans to conduct a formal reassessment of the market in 2031. Based on the competitive landscape at that time, the regulator may choose to either ease or tighten its controls on Openreach and the wider sector.
With the large-scale construction of fibre networks nearing its final stages, the regulatory and industry focus is now shifting toward ensuring a smooth migration of customers, fostering service innovation, and developing competitive offerings at the retail level. The success of this push for adoption will be critical for the UK’s long-term digital infrastructure goals.
