Market revenue growth turned (slightly) negative in Q1 2023, driven by weak demand and the waning of 2022 price boosts.

Next quarter will benefit from the high 2023 existing customer price increase, but this effect will wane across the year, and go into reverse next year due to lower inflation.

Other factors are mixed, with new-customer pricing tentatively rising, many smaller ISPs struggling, but altnet gains still likely to get worse before they get better.

Market revenue growth slowed to under 1% in Q4, driven by consumers economising in tough times through re-contracting and dropping add-ons.

Early 2023 is likely to be worse, with growth likely to turn negative again in Q1, again driven by ARPU with volumes more robust.

April price increases will give at least a temporary boost, but need to be managed very sensitively to avoid reputational damage and churn.

Market revenue growth continued to accelerate in Q2 to reach 3%, but broadband growth worryingly dipped as the lockdown boost waned.

Differing pricing dynamics (among other factors) led to very different outcomes for the main players, with BT’s growth surging to 7% while VMO2’s revenue stayed in decline.

Underlying trends of weakening broadband growth, keener pricing and customer bargain seeking point to slower growth ahead … until the next price increase.

UK altnet full fibre rollouts are accelerating, with an aggregate build pace close to that of Openreach, but customer acquisition is not growing at the same pace, and overbuild in the most attractive areas is becoming a significant issue.

Altnet business models remain challenging and are getting worse as Openreach builds out, and (although there are some notable exceptions) most will need to rapidly achieve scale and turn around their performance to survive.

Consolidation is very likely, along with business failures, and while some market share loss for Openreach looks likely as serious scale players emerge, the downside is limited, and even more so for retail ISPs.
