Broadband speeds in LL27
Share of LL27 premises by the fastest download speed available, averaged across all 47 postcodes in the district.
LL27's 47 postcodes are among the smallest in this batch. Gigabit at 77.1% is strong, superfast reaches 84.4%, and below-USO shortfalls are 7.9%. However, 10.9% below 10 Mbps despite decent gigabit reach creates a puzzle. No wireless presence means cable is the only modern technology available. Speed distribution shows 77.1% above 300 Mbps, 7.3% in the 30-300 band, and 10.9% below 10 Mbps. The small footprint and sharp divide suggest a micro-cluster where cable-served zones serve 77.1% and the remainder are isolated postcodes beyond cable reach.

LL27 broadband FAQs
Why is LL27 so polarised, strong gigabit but 10.9% below 10 Mbps?
Cable infrastructure clusters; outlying 47 postcodes lose coverage entirely. Some addresses enjoy gigabit; others sit on the fringe with nothing.
Should I move to LL27?
Only after verifying your specific address. The 10.9% below-10 cohort is substantial enough to be a real risk.
Could infrastructure improvements help LL27?
4G/5G deployment (currently absent) would likely be the next step, filling gaps the cable network leaves uncovered.
How representative is LL27 of North Wales?
LL27's mixture of good gigabit and poor outliers is typical for Welsh postcodes, infrastructure reaches some clusters; others lag decades behind.
