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 residential communications revenue growth bounced up in Q3 as we had predicted, on the back of continuing solid volume growth and improved ARPU growth driven by a series of price increases impacting in the quarter

The overall revenue growth of 6% was supported by some one-off factors, such as overlapping price increases and the launch of BT Sport Europe, but we believe that growth at this level will be sustained for the next two quarters at least

Looking forward, the impact of TalkTalk’s cyber-attack is uncertain in the detail, but it will clearly slow TalkTalk, benefit some of the others and may temporarily impact market volumes. Another area of competitive uncertainty is the impact of Virgin Media’s network extension as it gathers momentum into 2016, with all of the others likely to lose significant share in Virgin’s expanded areas

TalkTalk’s results revealed a challenging market environment, with it struggling to maintain its broadband subscriber base given the onslaught from larger and more differentiated competitors

Revenue growth was still a healthy 6%, but this was helped by acquisitions, price adjustments and low margin mobile, with its EBITDA falling despite the drop in broadband customer growth and associated costs

Its cost savings programme and marked price increases are likely to allow it to grow EBITDA this year and next, with the impact of the cyber-attack being significant but short-lived, but its declining retail customer base is a longer term concern

While volume growth remained robust in Q2, UK residential communications revenue growth did dip again during the quarter, to 3.6% from 4.5% in the previous quarter and 5%-6% for much of 2014

However, this largely related to the timing of price increases, with there being a host of headline and effective increases due before the end of the year. The combined effect of those announced so far is sufficient to push market growth back up to the 5%-6% range for both of the next two quarters

Looking ahead, the actual launch of BT Sport Europe in Q3 may have further impact, but a modest pre-launch effect suggests that this will not be dramatic. BT will be hoping that it at least drives an acceleration of growth in its TV base, given that it is still free for these users
