Wireless is absent. Below-USO presence is nil. The alignment of gigabit and ultrafast rates suggests infrastructure where intermediate steps are rare. The 24.9% conventional-superfast segment is material and represents older network infrastructure or postcodes awaiting upgrade. Provider competition exists at the gigabit tier. Households on conventional superfast can expect 30-99 Mbps service. The distribution indicates staggered fibre investment waves across the outcode, with gigabit deployment still incomplete. No premises fall entirely without service.
