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

On Wednesday Orange announced a simple new single tariff range for all its new contract users. Although there are some benefits to both consumers and Orange of tariff simplification, the main impact appears to be to increase the price of calls for off-peak users, which is a sensible strategy for Orange and consistent with other tariff increases we have seen recently. Orange may lose customers because of this, but it has helpfully given four weeks warning of the change to the other operators, who may react with changes of their own.

Weak economic growth is usually blamed, but we believe that other forms of communication are substituting for fixed voice calls. Substitution of fixed line calls by calls from mobile phones is increasingly less important. By contrast, our conclusion is that Internet-based communication (email and instant messaging) has recently become a far more important source of competition to fixed line voice calls.
