Market revenue growth fell in Q3 to below 1%, and may drop below zero next quarter as existing customer pricing comes under more pressure

New customer pricing is however rising, and average pricing should rise much further as ultrafast increases in availability and popularity 

Political enthusiasm for full fibre should be welcomed, although some specific plans are likely to do more harm than good if implemented literally
 

The UK mobile market suffered its worst performance in six years this quarter as competition heated up and regulation continued to bite

Vodafone’s unlimited tariffs have proven popular, reaching 5% of its contract base in one quarter, helping to drive its outperformance

Some reprieve is in prospect next quarter, before the impact of out-of-contract notifications and automatic discounts from February, although there is the possibility of pre-emptive moves bringing some of the effects forward 
 

Mobile sector returns are low, particularly for smaller-scale operators, with H3G earning less than its cost of capital. Regulatory initiatives, spectrum auctions and 5G look set to worsen this picture as H3G strives to gain viable scale

The UK mobile market posted its slowest growth in more than two years this quarter; just 0.5% service revenue growth although net adds were strong and churn was down

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
