WD23 broadband and area guide

WD23 splits between ultrafast capable premises and a smaller segment needing alternative approaches. Around 91.1% of postcodes report 300 Mbps availability. The remaining 8.9% divides into two groups: 7.4% get 30 to 300 Mbps, and 0.2% fall short of 10 Mbps. This distribution reflects a mature gigabit network reaching most of Harrow, with some postcodes still dependent on earlier generation infrastructure for their primary connectivity. Cable networks and fibre deployments have rolled out in phases across the borough. The resulting patchwork means core urban Harrow shows near-total gigabit saturation, while edge postcodes often rely on prior generation services.

Most households here can plan around gigabit capable services. Those in the 30 to 300 Mbps segment, primarily supporting streaming, video calls, and standard remote work, need only to verify their provider's coverage at point of house purchase. The very small below-10 Mbps tail represents postcodes where additional investigation or alternative services may be needed.
