Altnets in the UK: Waiting for the music to stop

In the next fixed line regulatory review—TAR 2026—Ofcom is likely to maintain light regulation on Openreach’s pricing levels, while also maintaining strict restrictions on its pricing structures, which both help altnets. 

On other matters, none of the interested parties (Openreach/altnets/ISPs) look like getting exactly what they want, but by and large the industry will likely get what it needs—regulatory stability with a broadly pro-investment slant.

The next TAR in 2031 is likely to be more dramatic, but by our estimates, even a full return to cost-based charging will not result in significant wholesale price cuts, which is likely to be a relief to longer term investors in BT and the altnets alike.

CityFibre has announced a deal to supply the second largest UK ISP Sky with wholesale broadband services, doubling its addressable target market at a stroke, in a blow to Openreach.

This may be just a foot in the door for CityFibre, but it is a critical one, and puts it firmly in the driving seat for altnet consolidation. There are also positives for VMO2 and other altnets hopeful of an eventual wholesale deal with Sky, and for retail ISPs now that the altnet sector is pitching towards wholesale away from retail.

While this is obviously bad news for Openreach, we see it more as an absence of a potential positive than something that might actually worsen current trends, and there are mitigating positives for the wider BT Group.

The Netomnia/Brsk merger will create the third largest UK altnet with 1.5 million homes passed in much the most significant altnet merger to date, combining two fast-growing, innovative challengers.

Both Netomnia and Brsk are burdened by eye-watering EBITDA losses; merger synergies alone are unlikely to solve this, with much more scale necessary, making further inorganic moves likely.

The merger creates an alternative prospect to the assumption that either CityFibre or VMO2/nexfibre will consolidate the market, but the combined group may prove more an enhanced target than an active acquirer.

While altnets continued their strong expansion in 2023, a slowdown in 2024 is looking very likely, with financing drying up due to tougher financial conditions and disappointing operating performances from some.

Consolidation is the obvious answer, and the altnets could consolidate into a pure wholesaler (via CityFibre), a retail/wholesale player, or could be absorbed into VMO2/nexfibre.

Which of these routes is taken, and how quickly, will have a profound impact on the structure of the industry, and all players should be careful what they wish for, with long-term outcomes hard to reliably predict in such a complex marketplace.

Project Gigabit, the process of awarding subsidies to cover the hardest-to-reach 10-15% of the UK with gigabit broadband, is well underway, with altnets having been awarded all of the contracts won so far, although these are only 5-10% of the prospective total.

While wholesale provision is mandatory under the contracts, logic and experience suggests that this option may prove impractical, leaving the national ISPs (such as BT, Sky and TalkTalk) at risk of losing up to 15% of the market, and consumers being denied hard-won choice.

Openreach would be well advised to build its own network in these areas using the ducts and poles of the subsidy winners (also mandated), to protect the prospects of its ISP customers and maintain consumer choice.

UK altnet full fibre rollouts are accelerating, with an aggregate build pace close to that of Openreach, but customer acquisition is not growing at the same pace, and overbuild in the most attractive areas is becoming a significant issue.

Altnet business models remain challenging and are getting worse as Openreach builds out, and (although there are some notable exceptions) most will need to rapidly achieve scale and turn around their performance to survive.

Consolidation is very likely, along with business failures, and while some market share loss for Openreach looks likely as serious scale players emerge, the downside is limited, and even more so for retail ISPs.
