Universal superfast coverage at 99.2% is remarkable across this Guildford zone. Only one postcode in the entire district falls short of the 30 Mbps superfast threshold.

GU12 broadband FAQs
Why does GU12 have 99.2% superfast but only 90% gigabit?
The 9.2% gap consists of postcodes capped at 30-299 Mbps, likely older cable or ADSL stretches where gigabit infrastructure hasn't yet been deployed.
Are there any postcodes in GU12 with inadequate broadband?
No. Zero postcodes fall below the USO minimum, making this district exceptional for coverage uniformity.
What share of GU12 can handle multiple 4K video streams simultaneously?
About 90%, matching the gigabit figure. Postcodes with 30-300 Mbps can manage one high-quality 4K stream but not multiple simultaneous feeds.
Is GU12 suitable for a remote office with cloud-based workflows?
Highly so. Nine in ten postcodes reach gigabit, and the remainder still exceed 30 Mbps, providing adequate bandwidth for video calls and collaborative tools.
