Broadband speeds in LL16
Share of LL16 premises by the fastest download speed available, averaged across all 644 postcodes in the district.
70.7% gigabit availability masks underlying strain. 4G/5G reaches only 37%, forcing reliance on cable and copper for most premises. Superfast is 81.2%, notably lower than LL18 or LL29 in the same region, suggesting substantial older copper infrastructure persists. Critically, 8.6% fall below 10 Mbps (double the rate in stronger nearby codes), and 1.9% miss the USO floor entirely. The 10.5% ceiling for 30-300 Mbps, though numerically small, contrasts with the 70.7% gigabit claim, suggesting that gigabit availability overstates lived experience for many households. This postcode area has islands of modern coverage separated by older infrastructure corridors.

LL16 broadband FAQs
Why does LL16 show gigabit yet 8.6% are below 10 Mbps?
Gigabit at 70.7% refers to available infrastructure; actual takeup varies. The below-10 Mbps cohort occupies postcodes where copper is the only option or 4G/5G signal is weak.
Should I get a speed test before moving to LL16?
Yes. With 8.6% below 10 Mbps and only 81.2% superfast, neighbourhood-level variation is high. Your exact street may be poorly served.
Will 4G/5G coverage expand in LL16?
Currently at 37%, it could expand. If mobile operators see demand, further coverage might lift speed minimums for outlier postcodes.
What speeds are typical in Conwy's LL16?
70.7% can theoretically reach gigabit, but 10.5% are capped around 30-300 Mbps and 8.6% face sub-10 Mbps reality, a wide spread.
