The speeds made possible by full fibre build are unnecessary for most users in the short term, giving limited commercial advantage to those that can offer them, but are likely to prove essential in the medium/long term.

The economics of full-scale, independent alternative networks look very challenging in our view – especially without the support of Sky – although there are some limited arbitrage/cherry-picking opportunities.

The Openreach full fibre model makes economic sense under Ofcom’s proposed regulatory framework, provided it retains the lion’s share of the market, although considerable risks remain.

UK residential communications market revenue growth fell again to 1.2%, with weakening ARPU growth the main driver. New customer pricing remains flat to down, and existing customers are being increasingly discounted, fuelling the ARPU weakness

High speed broadband adoption is proceeding apace, but the high speed premium is fairly thin, muting the impact on ARPU. Regulated wholesale price cuts from Openreach finalised today and due in April 2018 will not help

Looking forward, the March quarter will benefit from price timing effects at BT and Virgin Media, but we fear that the rest of 2018 will follow the current downward trend and the operators will need to adjust to an ex-growth environment
