Broadband speeds in CT15
Share of CT15 premises by the fastest download speed available, averaged across all 587 postcodes in the district.
CT15 is Dover's outlier and represents genuine underinvestment. Superfast coverage at 69.7% is the lowest outside CT4, and gigabit reaches only 22.5%, a stark drop reflecting rural or neglected infrastructure. Most premises (47.3%) sit in the 30 to 300 Mbps band, neither reaching superfast-fast nor gigabit capability. The below 10 Mbps tail is significant at 9.6%, and 0.4% fall outside the universal service obligation entirely. Fixed wireless is available to 42.7% but insufficient to cover all gaps. Speed distribution is 22.5% ultrafast, 47.3% superfast-midrange, 9.6% below 10 Mbps, and 0.4% unserved. This is not a district for households where broadband reliability is essential.

CT15 broadband FAQs
Is CT15 suitable for demanding broadband use?
No. Gigabit reaches only 22.5%, over half the district can access no better than 30 to 300 Mbps, and 9.6% lack 10 Mbps.
What should I do if my CT15 postcode lacks fast broadband?
Fixed wireless is available to 42.7% of the district; check if your address qualifies. Otherwise, Ofcom's universal service obligation may provide entitlement.
Why is CT15 so poorly connected compared to neighbouring Dover codes?
Likely rural geography or lower infrastructure investment. CT15's 22.5% gigabit suggests this outcode has received less cable or fibre deployment than other Dover zones.
Is moving to CT15 a risk for broadband?
Yes. Nearly one in ten premises report below 10 Mbps speeds. Verify your individual postcode before committing.
