Broadband speeds in LL17
Share of LL17 premises by the fastest download speed available, averaged across all 233 postcodes in the district.
74.2% gigabit availability sits above immediate neighbours, but the small footprint (233 postcodes) introduces statistical volatility. 4G/5G is the standout: 55.3% coverage indicates deliberate wireless infrastructure investment in this area. Superfast reaches 83.4%, respectable but still below larger urban postcodes. Below-USO shortfalls of 1.7% and 7.4% below 10 Mbps remain notable. The tight postcode count suggests LL17 may be a concentrated rural cluster served by one or two 4G/5G transmitters. Speed distribution shows 9.2% in the 30-300 Mbps zone, underscoring the split between gigabit-served and copper-dependent premises.

LL17 broadband FAQs
Why is fixed wireless so prevalent in LL17 (55.3%)?
The small geographic area (233 postcodes) may be served by a single fixed wireless tower or cluster, explaining the high penetration relative to nearby postcodes.
What about the 7.4% below 10 Mbps in LL17?
Even in fixed wireless-rich areas, terrain, distance from the transmitter or building obstruction can leave pockets underserved. These postcodes likely sit on the fringe.
Is LL17 worth considering despite the slow tail?
If you're located near the fixed wireless tower, yes. Latency and speed should be good. If further away, expect sub-10 Mbps. Check your specific address.
How small is LL17 compared to other outward codes?
233 postcodes is tiny, perhaps a single village or cluster of hamlets, versus 1,000+ in typical urban districts, so infrastructure investment per capita can be high.
