Broadband speeds in GU3
Share of GU3 premises by the fastest download speed available, averaged across all 400 postcodes in the district.
Superfast penetration at 90.5% leaves 38 postcodes without 30 Mbps baseline across this Guildford zone. Gigabit availability sits at 57.6%, with high-speed marginally higher at 58.7%, a 1.1% gap suggesting pockets of 300 Mbps high-speed without full gigabit capacity. Approximately 230 postcodes achieve gigabit speeds through available cable infrastructure. The middle tier claims 31.8% of postcodes, roughly one third or 127 premises with speeds between 30 and 300 Mbps. This substantial presence indicates considerable older infrastructure or uneven cable modernisation. Critically, 3.5% fall below 10 Mbps, affecting roughly 14 postcodes using legacy systems, and zero miss the USO floor. GU3 ranks mid-tier for Guildford overall. Superfast coverage is broad, yet gigabit penetration at 57.6% trails well-connected neighbours like GU12.
