Broadband speeds in GU1
Share of GU1 premises by the fastest download speed available, averaged across all 906 postcodes in the district.
Gigabit at 84.1% and superfast at 97.8% reveal a primarily cable-served urban area across 906 postcodes. The 13.7% superfast-only band (30 to 300 Mbps) is minimal, and only 0.1% fall below 10 Mbps, a negligible tail reflecting Guildford's urban density and infrastructure maturity. Cable networks dominate, concentrated in urban clusters and main access routes. Urban density justifies intensive cable investment uneconomical in dispersed areas. Most Guildford residents either have gigabit or solid superfast backup, creating reliable modern connectivity. No full fibre deployment is recorded, meaning cable remains the sole ultrafast delivery vehicle. The tight distribution ensures postcode-to-postcode variation is minimal; properties can assume gigabit or solid superfast baseline availability.
