Broadband speeds in SO51
Share of SO51 premises by the fastest download speed available, averaged across all 850 postcodes in the district.
This postcode sits in the middle tier of New Forest coverage. Gigabit access is 59%, adequate but not premium. Superfast is 89.6%, meaning most postcodes clear the baseline tier. The tail matters. 3.7% fall below 10 Mbps, and 0.6% sit outside the USO. Just over three in ten postcodes occupy the 30 to 300 Mbps range at 30.6%, a high share for this middling bracket. This suggests broader reliance on superfast FTTP without gigabit cable or fibre. The speed distribution skews toward the middle rather than the top, typical of mixed infrastructure areas.
