Broadband speeds in N21
Share of N21 premises by the fastest download speed available, averaged across all 533 postcodes in the district.
Full fibre and gigabit both reach 91.1% of 533 postcodes, indicating tight alignment and fibre-centric architecture. Only 6.1% settle into the 30-300 Mbps band, and no postcodes fall below. Superfast (97.3%) is effectively universal. N21 demonstrates complete network saturation where one operator's fibre footprint drives all speed tiers. Speed distribution is remarkably narrow: postcodes sit firmly in either gigabit or superfast bands with minimal variation. No legacy copper tails or cable alternatives complicate the picture. This uniformity across more than 500 postcodes reflects systematic modern fibre deployment completed borough-wide.
