SE3 broadband and area guide

Full fibre infrastructure in SE3 covers 71.2 per cent of the 757 postcodes, below even the reduced UK average for fibre-passed premises. The speed distribution highlights this: 71.6 per cent access 300 Mbps or higher, whilst 26.9 per cent remain in the 30 to 300 Mbps range. Superfast availability at 98.5 per cent is solid, but the gap between superfast and gigabit suggests that fibre hasn't penetrated as deeply as in neighbouring districts. SE3 reflects Greenwich's patchier infrastructure market, where cable and fibre deployment have been less complete than in inner London. The postcode's large population of 757 postcodes means variation between individual postcodes can be substantial. Areas closer to town centres may have better fibre access than peripheral zones. Households in the 27 per cent without gigabit typically reach 50 to 100 Mbps, adequate for everyday work but constrained for large uploads.

Greenwich's SE3 area reflects older or lower-priority investment zones where copper and limited cable deployment still dominate. Households here should validate their specific postcode before assuming fibre availability, as the district average masks postcode-level variation.
