Broadband speeds in GU18
Share of GU18 premises by the fastest download speed available, averaged across all 143 postcodes in the district.
Superfast penetration is solid at 96.8%, ensuring just five postcodes lack 30 Mbps baseline across this Surrey Heath zone. Yet gigabit availability drops to 66.4%, a notable contrast revealing infrastructure unevenness in the district. Approximately 95 postcodes achieve 300 Mbps or faster gigabit performance through cable deployment. Nearly one third of postcodes, 30.4% representing roughly 43 addresses, are confined to 30-300 Mbps speeds, a meaningful middle tier suggesting legacy systems or uneven cable modernisation. The absence of sub-10 Mbps postcodes indicates legacy speeds haven't taken hold here, but the gigabit lag signals incomplete cable upgrade or limited fibre deployment. Compared to nearby well-connected Surrey zones, GU18's gigabit gap is notable enough for households to verify their specific postcode before committing to moves or business plans.
