Consultation: Promoting competition and investment in fibre networks: Telecoms Access Review 2026-31

This document sets out Ofcom’s proposals for our regulation of the fixed telecoms markets that underpin broadband, mobile and business connections, for the period from April 2026 to March 2031. Our proposals are designed to promote competition and investment in high quality gigabit-capable networks – bringing faster, better broadband to people and businesses across the UK.

Since the conclusion of our last review in 2021 (the WFTMR), we have seen significant build by Openreach and a wide range of other companies, putting the UK on course to deliver wide availability of gigabit-capable networks. Gigabit-capable broadband is now available to more than 25 million homes (83% of the UK), and more than 20 million homes (69%) can access full-fibre broadband. Build by rival networks has also led to a significant increase in the number of premises with a choice of network.

We recognise the huge strides made by the industry in rolling out full-fibre networks. But there is more to do. Further investment is needed to deliver high-quality services to all parts of the UK. We also want to see network competition continue to develop where this is sustainable and where it delivers benefits to consumers.

We are proposing that BT has significant market power (SMP) in a number of markets, and so are proposing a regulatory framework to address the competition concerns that arise as a result. Our proposed remedies are the same as in our last review, except where recent or prospective market developments indicate an update is necessary to provide regulatory stability and maintain incentives for investment and network competition.
