On 3 June 2025, Enders Analysis co-hosted the annual Media and Telecoms 2025 & Beyond Conference with Deloitte, sponsored by Adobe, Barclays, Salesforce, Financial Times and SAS.

With over 700 attendees and more than 50 speakers from the TMT sector, including leading executives and industry experts, the conference focused on how new technologies, regulation, and infrastructure will impact the future of the industry.

This is the edited transcript of Session Three, covering: Vodafone’s strategy; BT’s strategy; the future of fibre; and challenges and opportunities for telcos.

The slowdown in telecoms traffic volume growth post-pandemic has persisted for far longer than a simple hangover effect would imply, and has spread from fixed broadband to mobile in many markets

The eventual emergence of the metaverse and/or AI-generated traffic may mitigate this trend, but it is hard to see growth ever returning to a sustained 30%+ per annum level, with around 10-15% likely to prove the new normal

While far from disastrous for telcos, it does have important implications, such as the need to structure pricing more carefully, focus on network quality over capacity, and be more wary of the threat (or opportunity) from MVNOs, FWA and satellite

Most regulations within the TAR26 condoc were continuations of the previous pro-investment regulations, albeit with little progress made on copper withdrawal, no extra help for the struggling altnets and a number of unexpected twists at the margin. 

Within the detail, the most significant hit is the return of cost-based price controls to some leased line charges, and across all of the proposed changes, Openreach has on balance fared worse than retail ISPs, albeit at a scale that is manageable within the BT Group.

Ofcom showed no inclination to offer any extra help to the struggling altnet industry, regarding its inefficiencies as being its own (and its investors’) problem, with consolidation the only sensible path forward for most.

The ‘big 4’ ISPs’ combined revenue remained in decline in Q4 2024 at -0.4%, partly due to a BT accounting quirk but mainly due to altnets gaining share

ARPU growth of 2% is roughly compensating for subscriber declines of 2%, but this ARPU growth is likely to weaken in 2025 as various boosts drop out

A recovery will come as the altnets slow in H2 2025 (if not before) due to their restrained expansion, which cannot come soon enough for the big ISPs

VMO2 had another mixed quarter to end a difficult 2024, with revenue growth improving but EBITDA growth falling, and other metrics mixed at best.

The company hopes to put this behind it with guidance for both revenue and EBITDA growth in 2025, a tough ask given current momentum.

Ultimately achieving or exceeding this may depend on altnet pressure receding, which we expect it to do, but perhaps more towards the end of the year than the beginning.

CityFibre has reported positive EBITDA in 2024, albeit at a slim 4% margin, and still needs further scale—and to successfully onboard its new wholesale customer Sky—to drive decent investment returns.

CityFibre’s organic build rate is dropping sharply as it (sensibly) looks set to rely on consolidation to achieve the required scale, with its organic build focused on Project Gigabit areas.

CityFibre remains well-positioned for consolidation, but this may take some time yet, with the altnet sector set to slow organic progress anyway in the interim.

The mid-sized UK altnets Zzoomm and FullFibre have agreed to merge, in what looks like an all-share merger of (nearly) equals, both of whom have been struggling to raise finance.

Why did they pick each other rather than the larger CityFibre/Netomnia/nexfibre options? Valuation may have been the key factor, but it has left them still vulnerably low scale with further consolidation necessary.

Much more consolidation is required for the sector to be sustainable in our view, and further financial distress may be required for realistic valuations to emerge.

UK mobile service revenue growth improved in Q3 to -0.8% from -1.7% in the previous quarter, a welcome turnaround after three quarters of declining growth. Pricing remains firm, data volume growth remains robust, and some of the one-off factors affecting the previous quarter have dropped out

Sky Mobile soft-launched at the end of 2016, and it is taking an aggressive approach with a very deep MVNO technical model with substantial fixed costs, a high advertising budget and ambitious internal subscriber targets. To date the fixed MVNOs have not had a substantial impact on the MNOs, targeting a customer base that is non-core, but with SIM-only on the rise this may change

Looking at recently released network performance statistics, the impact of spectrum disparities is clear, with EE both able to offer faster speeds nationwide due to its large blocks of 4G spectrum, and offer much faster speeds in London. EE also has a lead in geographic coverage, and is planning to push its coverage much further, creating a challenge for the other operators to keep up

TalkTalk’s broadband subscriber decline has re-accelerated, with retail weaker than wholesale, and its consumer revenue is declining at 6%. This is partly due to price change timings, partly due to last year’s cyber-attack, but also partly due to underlying weak retail broadband subscriber growth

EBITDA did grow strongly, although this was in part due to less subscriber growth. The new pricing plans will likely drive more short term revenue weakness, but could potentially drive lower churn in the medium term, and they have renewed TalkTalk’s price competitiveness, particularly on high speed products

Longer term, we still think that the company will find it challenging to stabilise its retail broadband base in the face of a slowing market and Virgin Media’s network extension, at least without significantly upping its marketing spend and sacrificing some margin

UK residential communications market revenue growth accelerated to 5.8% in Q3, from 5.0% in the previous quarter, helped by an overlapping price rise at BT, and supported by firm pricing and accelerating high speed adoption elsewhere

In contrast, volume growth in the core three products continues to slow, with little sign that this will ever re-accelerate. In the longer term we cannot see ARPU growth acceleration continuing to fully compensate, and market revenue growth might also have peaked

With Virgin Media’s continuing network extension and improving pay TV service putting pressure on the other operators, Sky and TalkTalk are protecting themselves by aggressively marketing high speed broadband. Correspondingly, this quarter marks the first time that Openreach’s high speed net adds were mostly derived outside of BT’s retail divisions
