Broadband speeds in DN18
Share of DN18 premises by the fastest download speed available, averaged across all 362 postcodes in the district.
Nearly nine in ten postcodes access cable gigabit networks across DN18's 362-postcode footprint. Superfast (30-300 Mbps) serves just 2.8% of postcodes, with 3.6% sitting below 10 Mbps. Below-USO postcodes account for 0.7%. Fixed wireless overlays 24.6%, complementing cable and copper as a secondary technology. DN18 shows a binary split between gigabit cable and low-speed areas, leaving minimal superfast middle ground. This binary distribution reflects infrastructure clustering. Small postcode count means within-postcode variation matters significantly. A household's speed depends as much on specific premises location as postcode average figures.

DN18 broadband FAQs
Why is fixed wireless coverage so high (24.6%) in DN18?
It supplements cable and copper, covering premises where hard-wired networks are absent or expensive to extend.
If my postcode is in the 3.6% below 10 Mbps, what are my options?
Check government scheme eligibility. You may qualify for Universal Service Obligation funding.
Is the 89.5% gigabit figure reliable for individual premises?
As a postcode average, yes. But within-postcode variation is real; 3.6% of postcodes go unserved. Verify your specific address.
Why is superfast so rare (2.8%) in DN18?
Binary infrastructure: gigabit cable where available, gaps where it isn't. Little middle ground.
