Broadband speeds in B4
Share of B4 premises by the fastest download speed available, averaged across all 158 postcodes in the district.
B4's connectivity lags the city average considerably. Superfast reaches 79.5% of postcodes, but gigabit falls to 72.7%. The 6.8-point gap signals a district where fibre deployment remains incomplete, leaving around 11 postcodes on improved copper or legacy cable. Speed split shows 70.5% at 300 Mbps+, 9% in the superfast range, and none below. Despite lower fibre penetration, B4 avoids postcodes below superfast, suggesting universal broadband has been achieved but gigabit density remains sparse. The infrastructure profile suggests a mix of modern fibre in some pockets and older copper networks elsewhere. Residents cannot assume gigabit access even if a postcode reaches superfast speeds.
