Broadband speeds in CF46
Share of CF46 premises by the fastest download speed available, averaged across all 347 postcodes in the district.
44.1% reach gigabit, 95.8% are superfast-capable. The 51.7% occupying the 30-300 Mbps bracket is the second-largest middle tier in the dataset. Only 1% fall below 10 Mbps. Wireless infrastructure is minimal (3.8%). This postcode shows a clear two-tier split: superfast-everywhere, gigabit-nowhere pattern. Most households are served reliably; those requiring gigabit will face limitations. CF46's profile suggests selective ultrafast deployment where gigabit was built in pockets rather than across the whole area. The 51.7% middle tier and 44.1% gigabit rate indicate roughly half the postcode was targeted for ultrafast investment, with the remainder left at superfast standard.
