Broadband speeds in NN18
Share of NN18 premises by the fastest download speed available, averaged across all 648 postcodes in the district.
NN18 distinguishes itself for one key metric: despite 90.9% gigabit, real-world download averages 324.9 Mbps (second-highest in the batch), whilst uploads drop to 57.7 Mbps (the lowest). Superfast reaches 98.6%; 93.3% get 300+ Mbps, 6.2% get 30-300 Mbps. No postcodes fall below 10 Mbps or miss USO. Across 648 postcodes, high downloads with weak uploads show heavy cable use prioritising streaming over symmetric fibre. This suits streaming and downloads but struggles with uploads. The asymmetry reflects the prevalence of cable and VDSL technologies in the area, which excel at downstream throughput but lag on upstream performance. Relocating to NN18 for download-heavy work thrives; requiring balanced uploads means NN15 is better. House prices are 363,080 pounds.

NN18 broadband FAQs
Why are downloads so high (324.9 Mbps) but uploads so low (57.7 Mbps)?
Asymmetric network contention or prevalent cable/VDSL services. Simultaneous heavy usage may throttle uploads while maintaining download throughput.
Is NN18 good for streaming but risky for uploads?
Yes. 324.9 Mbps excels at video streaming, but 57.7 Mbps upload is weak for video conferencing or large-file server backups.
How does gigabit availability differ from real-world speed?
90.9% have gigabit infrastructure available, but actual throughput at 324.9 Mbps suggests service constraints or older last-mile technology at some addresses.
Should I prioritise NN18?
Only if your work is download-heavy and uploads are minimal. NN15 (322.4 Mbps down, 137.1 Mbps up) offers better balance.
