Broadband speeds in SA39
Share of SA39 premises by the fastest download speed available, averaged across all 116 postcodes in the district.
Superfast reaches 67% of postcodes, significantly below the UK norm of 97%, indicating widespread distance from fibre-enabled exchanges. Gigabit coverage trails at 30.1%, with three-quarters of postcodes delivering speeds in the 30-300 Mbps range or below. The weak tail is notable: 21.4% of postcodes deliver below 10 Mbps, a concentration that points to geographic isolation or infrastructure gaps. Speeds between 30 and 300 Mbps cover 36.9% of postcodes, suggesting that many households sit in the middle tier without access to modern fibre. The distribution patterns reveal a district shaped more by settlement patterns than infrastructure investment, where distance from exchange points plays a determinative role in outcomes.
