Ofcom has proposed blocking a new Openreach commercial offer after finding that the full-fibre discount could damage competition and lead to higher prices over the longer term.
The telecoms regulator said the proposed Incremental New to Openreach Offer was not fair and reasonable because it targeted customers central to the growth of rival fibre networks. The offer would have given internet service providers monthly discounts for bringing new full-fibre customers onto Openreach’s network above their normal sign-up levels.
Discounts could have reached up to £9.50 per customer for as long as 30 months. Ofcom said the customers targeted by the proposal were especially valuable to alternative network operators, as they represent the new demand needed to support investment in competing full-fibre infrastructure.
The regulator has not objected to every commercial offer notified by Openreach. Two other proposals can proceed, including a one-off £50 incentive in areas where Openreach overlaps with Virgin Media O2 and a cap on average monthly rental charges for new high-speed connections. The proposed block is aimed at a specific pricing structure rather than a general refusal to allow Openreach to compete on price.
Ofcom has opened a consultation until 27 August 2026 before making a final decision. The intervention reflects the tension inside the UK’s fibre rollout: lower wholesale prices can benefit broadband providers and households in the near term, while targeted discounts from the dominant network may weaken the investment case for newer infrastructure competitors.
Openreach remains central to the UK broadband market. It supplies wholesale access used by providers including BT’s retail arm, Sky, TalkTalk, Vodafone, and others. Its scale gives it considerable commercial reach, while regulation seeks to preserve conditions in which smaller full-fibre networks can attract customers and build sufficient scale.
Digital infrastructure is entering a more difficult phase. Full-fibre deployment requires heavy capital expenditure, long payback periods, high connection volumes, and confidence that rivals will not be undercut before they can mature. Alternative networks have already been affected by rising financing costs, consolidation pressure, and slower customer migration than some early rollout assumptions suggested.
The consumer-facing argument is more complex than a simple dispute over cheaper broadband. Discounts can lower costs for providers and potentially households, but they can also concentrate market power if they make it harder for new networks to win the customers needed to survive. Ofcom’s task is to judge whether a commercial offer reflects healthy competition or uses scale to prevent others becoming viable competitors.
The decision also affects business connectivity. Companies increasingly depend on stable, high-capacity broadband for cloud systems, video communication, payments, customer service, remote work, and software-led operations. A competitive fibre market can support better service, coverage, and resilience, although fragmented or financially weak infrastructure providers can also create uncertainty.
Regulation in this market has to balance price, investment, coverage, and competition. Blocking a discount may look counterintuitive when households and small businesses are sensitive to costs, but Ofcom’s position is that lower prices today should not come at the expense of weaker network competition tomorrow.
Investors in telecoms infrastructure will watch the decision closely. The UK’s broadband market has drawn significant private capital, but the investment case depends on predictable regulation and credible routes to customer acquisition. If incumbents can selectively discount against challenger networks, funding conditions for alternative fibre build-outs may become harder.
Ofcom’s final decision will set an important marker for how commercial flexibility and market power are treated as fibre adoption turns increasingly towards customer capture. The next phase of the market is less about whether fibre can be built and more about who wins the connections that make those networks commercially sustainable.
