BT: The altnet threat starts to recede


10 February 2026

BT had a solid Q3 in financial terms, with various oneoffs hitting headline growth rates but underlying trends very much robust.

The highlight was reduced broadband line losses for Openreach, both in the quarter and in prospect, with retail altnets slowing faster than CityFibre improves.

Recent developments put the pace of altnet consolidation in doubt, but we expect reduced pressure on BT Consumer and Openreach in 2026 regardless.
