Broadband speeds in GU4
Share of GU4 premises by the fastest download speed available, averaged across all 484 postcodes in the district.
Guildford town centre and suburbs (GU4) have attracted dual cable-fibre investment, visible in the gigabit reach of 77.3%. Some 79.2% of postcodes support 300-plus Mbps, driven by overlapping network footprints. Superfast reaches 96.4%, nearly complete. The 17.2% in the 30-300 band are mostly older properties or pockets still awaiting gigabit fibre completion. Only 1% fall below 10 Mbps, a negligible tail suggesting no structural unserved pockets. Zero postcodes sit below universal service thresholds. This pattern reflects a town centre that has benefited from competitive network investment, attracting both cable duopoly upgrades and publicly-backed fibre schemes.
