UK Regulator Says Nexfibre's Netomnia Deal Could Hurt Competition, and the Remedies Are the Real Fight

Nexfibre Netomnia CMA: what the regulator found

Britain's Competition and Markets Authority provisionally found that Nexfibre's acquisition of fibre broadband operator Netomnia could substantially reduce competition in the wholesale supply of fixed broadband services. The finding, reported in early October 2026, is provisional, which means it is a warning shot, not a final verdict, but it is a serious one.

The deal itself is large. Nexfibre, a joint venture backed by Liberty Global, Telefonica, and InfraVia, agreed in February to buy the owner of Netomnia, the country's second-largest alternative fibre network, for 2 billion pounds. The combined business would add more than 3.4 million fibre premises and over 500,000 customers, reaching 8 million premises with full fibre by the end of 2027. That scale would make it a serious challenger to BT's national Openreach network.

Nexfibre pushed back. The company said the CMA's findings did not reflect the reality of Britain's fibre market, arguing that the deal prioritises the fibre investment the country needs and creates a scaled, sustainable challenger to Openreach. The buyers had until October 16 to submit remedies addressing the CMA's concerns before the regulator takes a final decision.

Why wholesale broadband competition matters

Most people never think about wholesale broadband. You buy internet from a retailer, and that retailer buys wholesale access to a physical network. If wholesale competition shrinks, retailers have fewer networks to choose from, prices rise, and investment in new areas slows. The CMA's job is to protect that upstream competition before consumers feel the downstream effects.

That is why this case matters beyond Britain. Regulators everywhere are wrestling with the same question: when does consolidation in infrastructure help, by creating a challenger big enough to compete, and when does it hurt, by removing a competitor? Nexfibre's argument is the first case: scale creates a challenger. The CMA's provisional finding is the second: removing Netomnia as an independent network reduces choice for wholesale buyers.

The tension is real, and there is no clean answer. A market with one giant incumbent and a dozen tiny challengers is not competitive either. The CMA has to judge whether this particular merger moves the market toward a healthier duopoly or toward a cosier one.

What happens next

Three paths are open. First, Nexfibre offers remedies, such as guaranteed wholesale access terms or divestments, that satisfy the CMA, and the deal proceeds with conditions. Second, the CMA rejects the remedies and blocks the deal, leaving Netomnia independent. Third, the parties walk away, which happens more often than people think when remedies get too expensive.

Watch the remedies closely, because they are where the real negotiation happens. A remedy that guarantees wholesale access on fair terms for a set period can preserve competition while allowing the scale benefits. A remedy that is vague or short-lived does neither. The details, not the headline, will decide whether this deal helps British broadband or hurts it.

The wider regulatory climate

The Nexfibre case lands in a busy regulatory season. The US Federal Trade Commission imposed neutrality conditions on Publicis's acquisition of LiveRamp, requiring five years of neutral access and firewalls around customer data. The European Union charged KKR over misleading regulators in the Telecom Italia deal. Regulators on both sides of the Atlantic are clearly willing to attach strings to deals, and equally willing to block them if the strings do not hold.

For telecoms and broadband specifically, the stakes are higher than in most sectors because the infrastructure lasts decades. A bad merger decision in broadband is not easily undone. Networks get built, customers get migrated, and reversing a merger years later is practically impossible. That is why the CMA is moving carefully, and why a provisional finding deserves attention even before it becomes final.

What this means for broadband customers

In the short term, nothing changes. Your broadband keeps working, and the merger is not complete. In the medium term, the outcome shapes how much choice your retailer has, which shapes prices and speeds. If the deal proceeds with strong wholesale remedies, customers could get a stronger challenger to Openreach and better competition. If it proceeds without them, or if the CMA blocks it and investment stalls, the outcome is worse.

The honest answer is that nobody knows yet, and the CMA's final decision is the thing to watch. Provisional findings are designed to force a serious conversation about remedies. That conversation is happening now, and its result will shape British broadband for years.
