Staying the course: Ofcom’s Telecoms Access Review 2026-31

Matthew Howett, Chief Executive of Assembly Research comments:

“The largely indiscernible reaction from Openreach and the altnets to Ofcom’s conclusion of its Telecoms Access Review suggests the regulator has probably struck the right balance at the midway point on a 10-year journey. The bigger issue of consolidation and how that leaves the market will fall to the CMA, with Ofcom right to only say it will provide input.”

In summary:

  • As we said at the consultation stage in March 2025, “Ofcom is right to stay the course halfway through what was always sold as a 10-year pro-investment framework” and that “we expect only limited change between now and the March 2026 statement”. Today’s statement confirms that, recognising that now is not the time to radically depart from what was outlined in 2021. The early reaction from Openreach, CityFibre and others is similar enough in tone, suggesting the regulator has probably struck the right balance.

  • At the consultation stage, Openreach had hoped for more on copper retirement and arguably that has been set in motion. While Ofcom has not fully defined the environment for copper deregulation, it is consulting on pricing flexibility for copper retirement, with the suggestion that charge controls could be removed where 90% of premises have access to fibre. In this scenario, you could envisage Openreach being able to increase prices for its legacy copper services.

  • Altnets raised PIA as one of the bigger concerns and we’ve seen some movement here from Ofcom, although not going as far as some would have liked by introducing alternative pricing structures for rural deployments. Instead, some prices will come down (lead-in charges and single bores), but no average pricing impact has been given due to the varying product mix that will be chosen by fibre builders. Ofcom’s commitment to PIA as a foundational remedy beyond 2031 will be reassuring for the many altnets that have made use of it.

  • Ofcom’s greatest challenge has been the need to balance the longer term need to invest with the uncertainty of how the market will develop over the next five years. Together with the CMA, the collection of regulators should have sufficient tools to respond, flex and adapt as required, and we’re not expecting them to revisit the market in any meaningful way before 2031.

  • On the specifics of consolidation, as you’d rightly expect, Ofcom was fairly tight lipped given it’s predominantly a matter for the CMA. The regulator has correctly focused on the principle of preserving competition over protecting specific competitors. While acknowledging the fragmented nature of the market, it was never Ofcom’s role to protect any one operator or business model – instead it was to give altnets an opportunity, but not a guarantee, to succeed. The next phase of the market will depend on how the CMA considers the level of sustainable network investment and footprint overlap in the consolidation of Netomnia. Our thoughts on that proposed transaction (and others) are available to clients here.

Economic Benefits of Digital Migration for Critical National Infrastructure Customers

About the study

BT asked Assembly for some economic modelling to illustrate the net benefits for digital migration (both fixed and mobile) for Critical National Infrastructure (CNI) customers, taking into account the costs of migration and the potential costs of inaction, particularly given rising fault rates on the PSTN. 

For the first time, we've lifted the lid on legacy network migration and worked to understand the scope and scale of how key UK industries are still relying on aging fixed and mobile networks. Our research found that while the energy and water sectors are already well into their migrations, it’s vital that others follow to avoid growing costs and missed efficiencies.

We were able to determine a series of net economic benefits of fixed and mobile migrations for the five sectors we studied which incorporated an honest accounting of the costs faced by firms making the switch.

What did we do?

To understand the progress to date in migrating away from the PSTN, 2G and 3G networks and evaluate the economic impact of adopting newer technologies, we: 

  • Identified and benchmarked the range of remaining legacy devices still in use in the CNI sectors, from phone lines and telecare systems to lift lines and sewage overflow monitors;

  • Estimated the likely cost of replacing these devices, considering possible savings from simplifying infrastructure;

  • Projected how the resilience of these legacy networks will continue to degrade and calculated the cost of inaction for firms that delay migration and experience longer and more frequent losses of service; and

  • Developed a series of economic models to predict the possible efficiencies of adopting digital connectivity, from reducing the electricity consumption of the water sector to cutting down on the number of false fire alarms each year.
