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.

Broadband market volume growth resumed its downward trend in the September quarter after a blip in the previous quarter that was likely caused by a wholesale transfer distorting the figures. Revenue growth, however, perked up to 1.9% from 1.7% in the previous quarter, an encouraging recovery especially given that it was not primarily driven by the timing of a price increase

ARPU growth improved across all four of the major operators, countering recent trends, with a focus on higher value offerings a common theme. High speed broadband adoption accelerated in the quarter across most operators, encouraged by Openreach’s volume discount offer, although this was partially driven by keener high speed pricing

Revenue growth at Virgin Media, Sky and TalkTalk converged at around 3%, with BT Consumer lagging at -1%. However, excluding the effect of BT’s shrinking telephony-only base and smoothing the sporadic boost of its 9-monthly price rise, BT Consumer’s revenue is in the middle of the pack at 3.0% 

TalkTalk had very solid Q2 and H1 results, with broadband net adds staying positive, high speed net adds accelerating, revenue growth above 3% and EBITDA rebounding back to growth

This was helped at the revenue line by a price increase in the quarter and in EBITDA terms by steep Openreach price reductions, with strong revenue growth and any EBITDA growth hard to replicate once these effects have annualised out

The company has nonetheless stabilised its subscriber base, revenue and profitability after some erratic years, with cost-cutting providing some potential for growth going forward

UK mobile market service revenue grew by 1.7% in Q2, up from 1.3% in the previous quarter, a disappointing result in the context of boosts from both IFRS 15 accounting and the annual price rises in the quarter

O2 was the star performer this quarter, with its service revenue growth leaping ahead to claim the top spot. BT/EE’s service revenue growth declined on an underlying basis, with weak contract net adds over the last six months catching up with it, and H3G and Vodafone were slightly improved and steady respectively excluding some one-off effects

Next quarter, the impact from the EU roaming cuts will annualise out, providing a substantial fillip to all operators. Ceteris paribus, this would put market growth in the vicinity of 4%, a figure not reached for years
