Broadband speeds in W1K
Share of W1K premises by the fastest download speed available, averaged across all 821 postcodes in the district.
This substantial Westminster postcode of 821 codes reaches gigabit in 82%, supported by full fibre at the same proportion. Superfast covers 88% across the district. Speed distribution clusters at the fast end: 82% achieve 300 Mbps or faster, 6% occupy the 30-300 Mbps band, with just one postcode (0.2%) below the Universal Service Obligation baseline. The 18% without gigabit, roughly 147 postcodes, likely concentrate in areas with heritage constraints or older building stock where fibre retrofit has faced practical obstacles. Even these postcodes reach superfast speeds. This postcode reflects the practical challenges of universal gigabit deployment in dense central London where historic preservation and complex building ownership complicate infrastructure work.
