Broadband speeds in LL23
Share of LL23 premises by the fastest download speed available, averaged across all 199 postcodes in the district.
LL23's small footprint masks considerable internal variation. Gigabit at 73.8% is decent, but the mini-postcode shows a 12% below-10 Mbps rate, suggesting pockets of severe underservice relative to postcode-level figures. Superfast is 83.7%, respectable but below larger neighbors. 4G/5G is entirely absent (0%), pointing to cable or copper dependence only. Below-USO shortfalls at 2.8% are material. Speed distribution shows 73.8% above 300 Mbps, 9.9% in the 30-300 band, and 12% below 10 Mbps. For a 199-postcode area, this spread is pronounced, likely indicating a hamlet or scattered cluster where cable serves core zones and the rest rely on older copper.
