Broadband speeds in SE17
Share of SE17 premises by the fastest download speed available, averaged across all 649 postcodes in the district.
Southwark SE17 sits at the edge of central London's gigabit plateau. 88.9% of premises reach full fibre; gigabit matches exactly. Superfast is universal at 98.1%. The speed composition skews heavily gigabit: 88.9% at 300+ Mbps, 9.2% between 30-300. The 9.2% middle tier and complete absence of below-superfast postcodes confirm SE17's mixed character (mostly residential and small commercial), all on modern networks. Only individual anomalies fall short of gigabit. Upload symmetry across fibre premises suits professional and personal use equally. The uniformity of SE17's fibre deployment shows that Southwark's infrastructure is fibre-first throughout.
