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.

Market revenue growth in the UK residential communications sector dipped down to 4.5% in Q3, from 5.4% in the previous quarter, but underlying revenue growth actually rose a touch by our estimates. In an intensely competitive quarter, BT lost ground relatively in broadband, with its net adds dropping compared to growth at the others, but BT still had the highest net adds in absolute terms, and continued to lead the way in revenue growth

With BT’s mooted bid for a mobile operator and quad play moves being highlighted by several operators, in this report we re-examine the evidence for consumer demand for quad play and find it still wanting. In the UK since 2001 there have been eight attempts at cross-selling between fixed and mobile, with five outright failures (three of which were from BT), two attempts that lost market share after an acquisition but are now growing modestly, and one attempt which has successfully gained modest share

The UK fixed business has better growth and far better margins than the mobile business. BT alone makes more cashflow in the UK than the entire mobile industry put together – the grass may always seem greener on the other side, but in this case it definitely is greener in fixed. The fixed operators have far more to lose than to gain, and for this reason alone they should perhaps be wary in their approach to quad play

TalkTalk had a solid quarter for net adds, helped by churn being held well under control, with broadband perking up, TV dipping down as pre-warned, and fibre and mobile both significantly accelerating

Revenue and ARPU growth accelerated, although not by as much as might have been expected given the timing of price rises, with the lower priced SimplyBroadband product likely still driving significant ARPU dilution

The company disappointed the financial markets with a warning of higher SACs in H2, and its medium term EBITDA margin target remains challenging, but continued revenue growth and margin expansion are nonetheless likely

Market revenue growth in the UK residential communications sector continued to be robust in Q2 2014 at 5.4%, a slight increase on the previous quarter, with continued volume growth and firm pricing countering weak call volumes and the negative impact of a VAT legislation change hitting Virgin Media and TalkTalk

BT was the fastest growing out of the ‘big four’ in revenue terms in Q2 even after the direct revenue impact of BT Sport is excluded, a remarkable turnaround after being in last place a year ago, driven by both volume and ARPU growth continuing to accelerate, with fibre helping both

Since the end of Q2, promotional activity has already intensified, particularly from BT and Sky around the start of the new football season, and churn is likely to be under more pressure at all of the operators, although the disruption is likely to be less severe than that experienced around the launch of BT Sport last year, and we expect all of the major players to continue to grow in net terms
